Build a Wireless LAN, Step by Step

    This tutorial will guide you through the process of planning, building, and testing a wireless home network. Although mainstream wireless networking has made amazing strides over the years, wireless technology and terminology remain a bit difficult for most of us to comprehend. This guide will help small business networkers, too!
You can build any typical wireless home network, a wireless LAN (WLAN), using this simple three-step approach:
1. Identify the WLAN design that’s best for your situation.2. Choose good wireless gear.3. Install gear and test the configured WLAN.
I’ll break down each of these steps in more detail.
This article assumes you’ve already made an informed decision to go wireless rather than build a traditional cabled network. Prices have dropped dramatically from a few years ago, when wireless gear was quite expensive, so networking hardware is much more affordable now, but wireless networks still aren’t for everyone (yet). If you’re unsure that wireless will really meet your needs be sure to research the different capabilities to decide what’s right for you.
Benefits of Wireless
Wireless offers tangible benefits over traditional wired networking. Ever tried to quickly look up a recipe on the Net while cooking in the kitchen? Do the kids need a networked computer in their bedroom for school projects?
Have you dreamed of sending email, instant messaging, or playing games while relaxing on your outdoor patio? These are just some of the things wireless can do for you:
Next Stop – Terminology
The field of computer networking once sat squarely in the domain of techies. Equipment manufacturers, service providers, and experts that study the field of networking tend to go quite heavy on technical jargon.
The wireless networking industry is gradually improving on this legacy, making products more consumer-friendly and easier to integrate into the home. But there is still much work for the industry to do. Let’s take a quick look at the common jargon of wireless home networking and what it all means.
When researching wireless equipment to buy, or talking about wireless networking with friends and family, you should have a solid understanding of this basic terminology.
We’ve already said that a WLAN is a typical wireless home network. That’s because a WLAN is a wireless LAN, and a LAN is a related group of networked computers situated in close physical proximity to each other. LANs can be found in many homes, schools, and businesses. Though it’s technically possible to have more than one LAN in your home, few do this in practice. In this tutorial, we explain how to build a single standard WLAN for your home.
Wi-Fi is an industry name used to market wireless networking products. You’ll find a black-and-white Wi-Fi logo or certification emblem on virtually any new wireless equipment you buy. Technically speaking, Wi-Fi signifies conformance to the 802.11 family of wireless communication standards (described below).
But because all mainstream wireless home network gear uses the 802.11 standards today, basically the term “Wi-Fi” merely distinguishes wireless equipment from other network gear.
What is 802.11a/802.11b/802.11g?
802.11a, 802.11b, and 802.11g represent three popular wireless communication standards. Wireless networks can be built using any of the three, but 802.11a is less compatible with the others and tends to be a more expensive option implemented only by larger businesses.
The security of wireless home and small business networks remains a concern for many. Just like we use radio or television receivers to tune into station broadcasts, it’s almost as easy to pick up signals from a nearby wireless home network.
Sure, credit card transactions on the Web may be secure, but imagine your neighbors spying on every email and instant message you send!
A few years ago, some techies popularized the practice of wardriving to raise awareness of this vulnerability in WLANs. With the help of cheap, home-made equipment, wardrivers walked or motored through neighborhoods snooping the wireless network traffic emanating from nearby homes. Some wardrivers even logged their computers onto unsuspecting people’s home WLANs, essentially stealing free computer resources and Internet access.
WEP was an important feature of wireless networks designed to improve their security. WEP scrambles (technically speaking, encrypts) network traffic mathematically so that other computers can understand it, but humans cannot read it. WEP technology became obsolete some years back and has been replaced with WPA and other security options. WPA helps protect your WLAN from wardrivers and nosy neighbors, and today, all popular wireless equipment supports it. Because WPA is a feature that can be turned on or off, you’ll simply need to ensure it is configured properly when setting up your network.
The five types of equipment found in wireless home networks are:
Some of this equipment is optional depending on your home network configuration. Let’s examine each piece in turn.
Wireless Network Adapters
Each device you wish to connect to a WLAN must possess a wireless network adapter. Wireless adapters are sometimes also called NICs, short for Network Interface Cards. Wireless adapters for desktop computers are often small PCI cards or sometimes card-like USB adapters. Wireless adapters for notebook computers resemble a thick credit card. Nowadays, though, an increasing number of wireless adapters are not cards but rather small chips embedded inside notebook or handheld computers.
Wireless network adapters contain a radio transmitter and receiver (transceiver). Wireless transceivers send and receive messages, translating, formatting, and generally organizing the flow of information between the computer and the network. Determining how many wireless network adapters you need to buy is the first critical step in building your home network. Check the technical specifications of your computers if you’re unsure whether they contain built-in wireless adapter chips.
A wireless access point serves as the central WLAN communication station. In fact, they are sometimes called base stations. Access points are thin, lightweight boxes with a series of LED lights on the face.
Access points join a wireless LAN to a pre-existing wired Ethernet network. Home networkers typically install an access point when they already own a broadband router and want to add wireless computers to their current setup. You must use either an access point or a wireless router (described below) to implement hybrid wired/wireless home networking.
Otherwise, you probably don’t need an access point.
A wireless router is a wireless access point with several other useful functions added. Like wired broadband routers, wireless routers also support Internet connection sharing and include firewall technology for improved network security. Wireless routers closely resemble access points.
A key benefit of both wireless routers and access points is scalability. Their strong built-in transceivers are designed to spread a wireless signal throughout the home. A home WLAN with a router or access point can better reach corner rooms and backyards, for example, than one without. Likewise, home wireless networks with a router or access point support many more computers than those without one. As we’ll explain in more detail later, if your wireless LAN design includes a router or access point, you must run all network adapters in so-called infrastructure mode; otherwise they must run in ad-hoc mode.
Wireless routers are a good choice for those building their first home network. See the following article for good examples of wireless router products for home networks:
Wireless network adapters, access points, and routers all utilize an antenna to assist in receiving signals on the WLAN. Some wireless antennas, like those on adapters, are internal to the unit. Other antennas, like those on many access points, are externally visible. The normal antennas shipped with wireless products provide sufficient reception in most cases, but you can also usually install an optional, add-on antenna to improve reception. You generally won’t know whether you’ll need this piece of equipment until after you finish your basic network setup.
Some manufacturers of wireless access points and routers also sell a small piece of equipment called a signal booster. Installed together with a wireless access point or router, a signal booster serves to increase the strength of the base station transmitter. It’s possible to use signal boosters and add-on antennas together, to improve both wireless network transmission and reception simultaneously.
Both antennas and signal boosters can be a useful addition to some home networks after the basics are in place. They can bring out-of-range computers back into range of the WLAN, and they can also improve network performance in some cases.
Now that you have a good understanding of the pieces of a wireless LAN, we’re ready to set them up according to your needs. Don’t worry if you haven’t settled on a configuration yet; we will cover all of them.
To maximize benefit from the directions below, have your answers ready for the following questions:
One wireless router supports one WLAN. Use a wireless router on your network if:
Try to install your wireless router in a central location within the home. The way Wi-Fi networking works, computers closer to the router (generally in the same room or in line of sight) realize better network speed than computers further away.
Connect the wireless router to a power outlet and optionally to a source of Internet connectivity. All wireless routers support broadband modems, and some support phone line connections to dial-up Internet service. If you need dial-up support, be sure to purchase a router having an RS-232 serial port. Finally, because wireless routers contain a built-in access point, you’re also free to connect a wired router, switch, or hub.
Next, choose your network name. In Wi-Fi networking, the network name is often called the SSID. Your router and all computers on the WLAN must share the same SSID. Although your router shipped with a default name set by the manufacturer, it’s best to change it for security reasons. Consult product documentation to find the network name for your particular wireless router, and follow this general advice for setting your SSID.
Last, follow the router documentation to enable WEP security, turn on firewall features, and set any other recommended parameters.
One wireless access point supports one WLAN. Use a wireless access point on your home network if:
Install your access point in a central location, if possible. Connect power and a dial-up Internet connection, if desired. Also cable the access point to your LAN router, switch or hub.
You won’t have a firewall to configure, of course, but you still must set a network name and enable WEP on your access point at this stage.
Configure your adapters after setting up the wireless router or access point (if you have one). Insert the adapters into your computers as explained in your product documentation. Wi-Fi adapters require TCP/IP be installed on the host computer.
Manufacturers each provide configuration utilities for their adapters. On the Windows operating system, for example, adapters generally have their own graphic user interface (GUI) accessible from the Start Menu or taskbar after the hardware is installed. Here’s where you set the network name (SSID) and turn on WEP. You can also set a few other parameters as described in the next section. Remember, all of your wireless adapters must use the same parameter settings for your WLAN to function properly.
Every Wi-Fi adapter requires you to choose between infrastructure mode (called access point mode in some configuration tools) and ad-hoc wireless (peer-to-peer) mode. When using a wireless access point or router, set every wireless adapter for infrastructure mode. In this mode, wireless adapters automatically detect and set their WLAN channel number to match the access point (router).
Alternatively, set all wireless adapters to use ad hoc mode. When you enable this mode, you’ll see a separate setting for channel number. All adapters on your ad hoc wireless LAN need matching channel numbers.
Ad-hoc home WLAN configurations work fine in homes with only a few computers situated fairly close to each other. You can also use this configuration as a fallback option if your access point or router breaks.
Configuring Software Internet Connection Sharing
As shown in the diagram, you can share an Internet connection across an ad hoc wireless network. To do this, designate one of your computers as the host (effectively a substitute for a router). That computer will keep the modem connection and must obviously be powered on whenever the network is in use. Microsoft Windows offers a feature called Internet Connection Sharing (ICS) that works with ad hoc WLANs.
Now let’s cover some of the finer points you need to know about home wireless networks.
When installing a Wi-Fi router (or access point), beware of signal interference from other home appliances. In particular, do not install the unit within 3-10 feet (about 1-3 m) from a microwave oven. Other common sources of wireless interference are 2.4 GHz cordless phones, baby monitors, garage door openers, and some home automation devices.
If you live in a home with brick or plaster walls, or one with metal framing, you’re may encounter difficulty maintaining a strong network signal between rooms. Wi-Fi is designed to support signal range up to 300 feet (about 100 m), but physical barriers reduce this range substantially. All 802.11 communications (802.11a and other 5 GHz radios more than 2.4 GHz) are affected by obstructions; keep this in mind when installing your devices.
Wireless Routers / Access Point Interference from Outside
In densely populated areas, it’s not uncommon for wireless signals from one person’s home network to penetrate a neighboring home and interfere with their network. This happens when both households set conflicting communication channels. Fortunately, when configuring a router (access point), you can (except in a few locales) change the channel number employed.
In the United States, for example, you may choose any Wi-Fi channel number between 1 and 11. If you encounter interference from neighbors, you should coordinate channel settings with them. Simply using different channel numbers won’t always solve the problem. However, if both parties use a different one of the channel numbers 1, 6 or 11, that will guarantee elimination of cross-network interference.
MAC Address Filtering
Newer wireless routers (access points) support a handy security feature called MAC address filtering. This feature allows you to register wireless adapters with your router (access point) and force the unit to reject communications from any wireless device that isn’t on your list. MAC address filtering combined with strong Wi-Fi encryption (ideally WPA2 or better) affords very good security protection.
Wireless Adapter Profiles
Many wireless adapters support a feature called profiles that allows you to set up and save multiple WLAN configurations. For example, you can create an ad hoc configuration for your home WLAN and an infrastructure mode configuration for your office, then switch between the two profiles as needed. I recommend setting up profiles on any computers you plan to move between your home network and some other WLAN; the time you spend now will save much more time and aggravation later.
Among the options you’ll see for activating wireless security on home networks, WPA2 is considered best. Some gear might not support this higher level of protection, though. Ordinary WPA works well on most networks and is a suitable fallback alternative to WPA2. Try to avoid using older WEP technologies whenever possible except as a last resort. WEP helps prevent casual people from logging into your network but offers minimal protection against attackers.
To set up wireless security, choose a method and assign a long code number called a key or passphrase to the router and all of your devices. Matching security settings must be configured on both the router and the client device for the wireless connection to work. Keep your passphrase secret, as others can easily join your network once they know the code.
If you’ve finished installing the components, but your home network isn’t functioning correctly, troubleshoot methodically:
Finally, don’t be surprised if your network’s performance doesn’t match numbers quoted by equipment manufacturers. For example, although 802.11g equipment technically supports 54 Mbps bandwidth, that is a theoretical maximum never achieved in practice. A significant amount of Wi-Fi network bandwidth is consumed by overhead that you cannot control. Expect to see more than about one-half the maximum bandwidth (about 20 Mbps at most for a 54 Mbps link) on your home network.

How to Make a Homemade WiFi Wlan Antenna

Before you start making your homemade WiFi Wlan Antenna, you need to prepare the required materials. The items you will need are a poultry netting or commonly known as chicken wire, a length of hollow pipe, a long thin piece of wood, wires, an USB cord, a thumb-sized USB Wi-Fi transceiver and an electric drill.

After preparing all the listed materials, you will need to ensure that your computer or laptop is not connected to any wireless connection. This will be helpful to set up a connection with the network later on. However if your computer has not been connected to any wireless connection before, you may skip this step.

The next procedure is to secure the pipe onto the center of the chicken wire. The pipe’s length should be tall enough to avoid obstructions from any trees, buildings or other structures. The length of the chicken wire should be about a meter long in order for your homemade Wi-Fi antenna to work effectively. You may choose to use a longer pipe to extend the signal detection.

By using a tie wire, the long piece of pipe is attached to the chicken wire. To perform this, the tie wire is slid under the pipe and being pulled up tight against the pipe. Several tie wires are placed diagonally around the pipe to make sure it is tightly fixed onto the chicken wire. The other length of tie wire is connected onto the long piece of wood attached crossways to the chicken wire. Having the tie wire will help support the chicken wire from slipping or bending in case there were strong winds.

Next two holes are drilled in the upper part of the long pipe and a few pieces of tie wires are being pierced through the holes. Once you are done, you will need to place the antenna in an open location to avoid any interference. Then pull through a USB cord inside the pipe and secure it to the pipe with tie wires. After that, the USB Wi-Fi transceiver should be attached to the USB connector. The USB transceiver is tied with tie wires to keep it firm.

When the transceiver is connected to the antenna, link the other end of the USB cord to your laptop or computer. The wireless connection will be automatically detected and it will display an icon of notification. Then your homemade Wi-Fi antenna is ready to be used.

Types of Wireless Router Antennas

Wireless routers are devices that you could connect your modem to and broadcast a signal which wireless devices could pick up. Wireless routers are used for laptops and sometimes utilized for home networks. You could take an antenna for every desktop computer (in laptops, it comes with 1 built in) and simply have one router to send the wireless signal to all of your computers immediately. That means you do not have to worry on extensive cords and wires all over your office or house.In particular, a wireless router antenna is used to get radio waves, which are produced by the router, and converts them back to electric pulses, which the PC could translate into data.

There are 2 types of this type of antenna. The first type the omni-directional antenna. This could boost signal a bit higher on all directions. This would be great if you are either setting up a business where in you provide free wifi or you just want to set up the router in the middle of your office or house. You can freely utilize your wireless devices all through your home. The second type of antenna is called the directional antenna. This antenna is used to broadcast a very strong signal in a direction. Assuming you wanted to set up a business and you only utilize wireless devices on a particular side of the building. Since omni-directional antennas are not as powerful like the directional antennas (the reason for this is because they have to distribute the signal equally in all directions), you can simply set up a directional antenna anywhere in your house and point it in that direction.

A range extender is a directional antenna. The advantage of this type of antenna from that of the first one mentioned is that it could be applied to both omni directional and directional antennas. This antenna as well operates with the antenna that you already have. The way it works is just like a mirror. You just have to plug in your router like the usual way of setting it up. However, this time, the signal it produces would bounce-off and the range extender shoots it back out on a higher frequency. Say for instance you have a restaurant and you don’t only want to offer your customers a free wifi access, but you as well want to offer the entire surrounding of your restaurant a free wifi (for whatever reason). You could easily do that because the range extender could generally pickup signals up to 1 to 3 miles.Our company mainly provides 4G WiFi Router Antenna,4G high gain indoor antenna,wifi outdoor mimo antenna,Long Range UHF RFID antenna and so on.

Dielectric Antenna Solves Tough Integration Problems

One nagging problem with microwave antennas in cell phones and other products is that the user’s presence seriously affects them. Bringing the antenna near the user detunes it. Also, a huge portion of the radiated or received energy is lost in the user’s hand, head, or body. The near-field energy produced by the antenna is literally sucked into any nearby object with a dielectric constant greater than one, which means just about everything else. Most of this energy is wasted, making transmission and reception considerably worse than desired.

Sarantel Ltd. has come up with a solution in its GeoHelix antenna. The antenna conductor is a helical loop made on a ceramic dielectric. This design confines the near field to a volume not much larger than the antenna itself. The twisted loop structure also reduces induced noise and serves as a superior filter. A built-in balun performs unbalanced to balanced conversion.

Because the antenna is a balanced loop, no ground plane is required in the cell phone or other device, which is usually the case. The resulting antenna is about the size of a pencil eraser, providing a 15% to 50% greater transmission range over antennas several times its size. The radiation pattern is omnidirectional and right-hand circular polarization (RHCP), which is compatible with GPS systems. It also receives either vertical or horizontal polarized signals equally well. A key benefit of the antenna is that it greatly reduces specific absorption rate (SAR), a measure of the amount of power radiated and absorbed into a unit mass of body tissue. The dielectric loading of the antenna core and the twisted conductors reduce the rear field to minimize the local absorption effects.

The multipatented GeoHelix antennas are now available for GPS service in GPS receivers and in cell phones that use GPS as the basis for implementing the E911 mandate. Versions for WCDMA 3G cell phones and Wi-Fi wireless local-area-network (WLAN) service are in development and will be available shortly.

Four Types of Omni Directional Antennas

Omni Directional Antennas are a class of Antennas that radiate uniform wave power in all directions in a plane. These devices can give out various frequencies of wave power such as 900 MHz Omni Directional Antenna, 900 MHz Omni Directional Antennas etc. The radiation pattern of such Antennas is usually termed as doughnut shaped as it covers all directions in a plane and the frequency starts decreasing with reducing elevation angle. This device of communication is mostly used in radio broadcasting Antennas, mobile devices and walkie-talkies.

Types

Omni directional Antennas are also used in various wireless network applications to transmit radiated signals and receive such signals simultaneously. Different applications require a variety of such Antennas. The types of Antennas commonly available are types of antennas:

Rubber Duck Antenna: This one as the name suggest, is a rubber dipole antenna used in most default access and wireless communications such as routers. The device includes a compact build along with a rubber or plastic sheath, which allows the antenna flexibility. New versions of this antenna include plastic sheathing that comprise of a gain between 2 and 2.2 decibel isotropic.

Spider Omni Directional Antenna: The Spider is a simple design among Omni Directional Antennas. This type of Antennas contain a standard N-type chassis mount connector along with short lengths of stiff wire fenced into each corner hole. This Antenna offers a gain up to 3 decibels isotropic.

Ceiling Mount Omni Directional Antennas: This design is mostly preferable for an indoor area with an aim of discreet frequency serving. Such antennas have the luxury of being mounted on the ceiling and look similar to lights. These Antennas are often uses as Wi-Fi hotspots where multiple devices can catch frequencies at once without any disturbance. These devices have a 3.5 decibel isotropic gain, meaning it can cover a greater floor space.

Outdoor Omni Directional Antennas: Also called as GP Antennas these Antennas can provide a 360 degree area coverage. These devices are also available in weatherproof and waterproof option meant for setting up in outdoor areas. Outdoor Antennas are bigger in width and height in comparison to other Antennas and can gain up to 12 decibel isotropic, meaning a coverage of a colony or society.

Omni Directional wave patterns are created with the help of simple and practical Antennas such as monopole and dipole Antennas that include only one or maximum two straight rods. All of the antenna products at Whwireless.com.

Outdoor Wireless Mesh antenna

Pros: This solution has significant power and capacity. Antennas are all integrated and there’s basically only one unit that would need to be installed on the exterior of the school. This is simple and clean.

Cons: The problem with the “outdoor-in” type of wireless design is that you can’t consistently shoot through buildings and expect the Wi-Fi to work. Buildings are constructed differently. What you end up with is several coverage holes inside the intended coverage area. The units are big and bulky, expensive for this type of deployment, and if you’ve got rows of mobile classrooms they can’t shoot far enough to guarantee coverage in the units behind the front rows.

When to use Outdoor Wireless Antenna Arrays: We don’t recommend this system for mobile classrooms. It will not perform consistently for this type of deployment.
Mobile Classroom Solution #4- Outdoor Wireless Mesh Router:

Outdoor wireless mesh routers were designed for well, outdoor use. They don’t function like an indoor campus WLAN. These are the type of systems that are used during the Olympics to provide large scale wireless for entire city blocks with backhaul for Surveillance Cameras to provide real time data feeds for police and fire departments in case of emergency. It’s kind of a hybrid of the first three solutions we’ve discussed. It’s like a fast wireless bridge in that it has good backhaul capability, but it also has features similar to an indoor WLAN in that you can do things like prioritize certain types of traffic.  But with a Wireless Mesh Router you can actually “hop” without losing the speed. When an indoor WLAN system is used to hop it can lose 50% of the throughput each hop, but with a good outdoor wireless mesh product- you’ll lose less than 10% of the throughput.

Outdoor Wireless Mesh antenna design

Outdoor wireless mesh routerPros:  These are hands down the most flexible solution because we’re using a system that was designed for outdoor use. They can be put up quickly in that the units have an internal antenna system so they have the wireless router, software, and antenna system built inside each unit. They are fast, extremely robust, have built in failover, and the most flexible of all of the outdoor wireless solutions.  Oh, and they’re powerful- they can create a wireless link up to 6 miles away.

Cons: More expensive than a wireless bridge (probably less expensive than option #2). This system operates independently from the campus WLAN. If you want to monitor both your campus WLAN and your connections to the mobile classrooms you’ll need wireless network management software that can view both systems from one interface.

When to use Wireless Mesh Routers: If you’ve got a larger school system that wants to standardize on wireless solution that can handle any of your mobile classroom needs whether you have one mobile unit or fifty, this is it. With Outdoor Mesh, you have no limits. Matter of fact you could also hit sports fields, press boxes, and all of those other areas you’ve been dying to light up. The world is yours to connect.

LTE Antennas apply to Indoor Distribution

With the rapid development of Internet users and more and more high-rise buildings in the city,the application of LTE network density, usage and coverage requirements is also rising.
The large scale Building have the high quality, it has the strong shielding effect for the the network signal,
In the low level of large buildings, underground mall, underground parking lot, commercial venues, sports venues, electronic factories, food factories, production work shop,supermarket,the LTE internet signal even more weaker.The internet cannot normally use mainly, it thus forming the blind area and shadow area of mobile network. The distribution of the indoor network can solve this type problem effectively.

LTE indoor distribution system is aim at indoor user group,to improve the signal Internet environment in building. It’s using the outdoor antennas to  receive and transmit the signal from the long distance base station and then use the indoor antenna distribution system to make the signal is uniformly distributed in every area, thereby to ensure there have the ideal signal coverage in the indoor area. LTE indoor signal distribution system is including of all kinds of LTE indoor antenna,LPDA antenna,Yagi antenna, LTE indoor ceiling mount antenna,wall mount antenna, Power Splitters passive components,RF cables assembly and Repeaters, etc.
