    How to secure wireless communication links in public safety? https://www.whwireless.com Estimated 5 minute to finish reading     As the weather gets hotter, fire rescue becomes a more important part of public safety. Since most fire departments cover large geographic areas and have growing populations, fire departments are responsible for large areas, including sparsely populated areas that lack cell phone service.     In order to respond to fire emergencies in a timely manner, fire departments need to enhance their wireless equipment signals to ensure reliable wireless connectivity at stations and incident sites at all times. In addition, they wanted to add failover capabilities to their mobile data coverage to always maintain wireless connectivity and be able to keep service uninterrupted in the event of an outage or network failure. The Solution The fire department installed two antennas on each fire truck with corresponding routers. Since the antennas feature four ultra-broadband 5G LTE components, four WiFi 2.4/5.0GHz components and a high-performance GPS/GNSS antenna, Hologic gave them the robust and reliable wireless connectivity they needed.     Designed for the latest generation of LTE Cat 18/20 routers and devices, this rugged low-profile antenna consists of up to 11 components and contains four isolated high-performance antenna components covering 617-960/1710-6000MHz, up to six optional dual-band components covering 2.4 and 5.0/7.2GHz with WiFi support for MiMo/Split set operation, and an optional high performance GPS/GNSS antenna with integrated 26dB gain LNA and high quality filtering, capable of providing unparalleled positioning accuracy.     It can support many terminal uses without the need for a metal grounding layer, maintaining a high level of performance even when mounted on non-metallic surfaces. And is designed to be suitable for operation in the harshest conditions.     By installing two antennas on each fire truck, the fire department ensures that any location in the area can have flexible wireless communications and seamless connectivity. They also gave feedback that some of the surrounding areas where connectivity was once impossible no longer have any problems, and the speed is even higher than it was before for the entire district, which greatly improves the efficiency and safety of the entire firefighting process.

    High-performance antennas enable stable connectivity in remote areas 2023-02-21
    High-performance antennas enable stable connectivity in remote areas https://www.whwireless.com/ Estimated 5minutes to finish reading Background and Challenges South Wales Police is the largest police force in Wales, serving 1.3 million people in an area of over 2,000 square kilometers, or 42% of the Welsh population, yet there was a huge challenge in their work, the 4G cellular solution they deployed could not achieve the connectivity they needed, and it was important to be able to work in a wide and varied area without having to return to the station. They needed a high-performance antenna to help them achieve connectivity in even the most remote areas, one that would not only help the devices connect, but also provide Wi-Fi hotspots around the vehicle. The Solution The 5G MiMo antenna has up to 11 independently fed antennas in a single dome housing with four isolated high performance antenna units that can cover 617-960/1710-6000MHz, while up to six optional dual-band elements cover 2.4 and 5.0/7.2GHz and support MiMo/diversity operation for Wi-Fi. And one of the optional high-performance GPS/GNSS antennas has an integrated 26dB gain low-noise amplifier and high-quality filtering to provide high-precision positioning. Available in black or white, the 5G MiMo antenna features multiple antenna functions in one housing, along with a standard front-connector antenna connector, and a logo for connecting cables for easy cable identification and installation. The single-hole mount design reduces vehicle damage, installation time and cost, and can be mounted on metal or non-metallic panel surfaces for FirstNet (US) and SN (UK) public safety networks. The 5G MiMo antenna is small and versatile, measuring 81mm in height, 180mm in width and weighing only 0.9kg, and can be used in police and law enforcement, EMS and firefighting, public transportation buses and coaches, and utility vehicles. Application Outlook The 5G MiMo antenna can be used as part of a router to help solve connectivity issues and can provide signal coverage in remote areas. For the South Wales Police, this can help to dramatically reduce working hours and improve efficiency, as well as upload and update information outside the vehicle, enabling communication with the system outside the vehicle and providing much needed connectivity while on the job. The stable connectivity brought by the 5G MiMo antenna will not only enable more efficient work for public safety and transportation, but will also open up greater possibilities for the future application of technologies such as facial recognition. https://www.whwireless.com/

  • How to ensure the stability of private networks through antennas?
    How to ensure the stability of private networks through antennas? 2023-01-12
    How to ensure the stability of private networks through antennas? https://www.whwireless.com/ Estimated 5minutes to finish reading Private Networks Whether it's retail, office, restaurant or warehouse, different departments and applications in an enterprise private network require a stable wireless connection. Traditional landlines are often used for communication, but in some cases wireless connectivity is a simpler and easier option that is reliable and cost-effective, and can be deployed quickly and easily in a variety of environments. As cellular network technology evolves and 4G/5G LTE is increasingly used in different regions and applications, enterprise private wireless networks are also advancing to avoid any connectivity outages due to failures. As the usage of enterprise networks continues to grow, so does the need for antenna solutions to meet different applications. While many routers are equipped with low-cost paddle cell antennas, in many cases, these antennas are not sufficient to allow users to obtain the required data speeds, thus requiring more sophisticated products to improve the wireless connectivity usage experience.   Depending on the actual application scenario and requirements, built-in or external antennas, wall or panel mount, SiSo or 2x2/4x4 MiMo, or even a combined solution with GPS/GNSS and WiFi may be required to ensure a more reliable, stable and fast connection.

  • What is CBRS in the wireless world?
    What is CBRS in the wireless world? 2022-12-08
    What is CBRS in the wireless world? Citizens Broadband Radio Service is shared wireless spectrum in the 3.5 GHz band, which could have significant landscape implications for building dedicated LTE networks as well as expanding public 4G and 5G services. First, CBRS is an acronym for Citzens Broadband Radio Service, and for IT professionals, the result is that it enables enterprises to every build their own private 4G/5G networks and improve service providers' 4G/5G offerings. Here's a primer on CBRS - because you'll want to know this. CB, just like in the history of B radio? Pi, good buddy, this has nothing to do with the Citizens' Band radio service used by truckers for voice communications, which is located in the 27MH slow band in the U.S. CBRS is located in the 3.5GHz band. So what is CBRS? CBRS is a radio spectrum band from 3.5GHz to 3.7GHz, which the FCC has designated as shared between three tiers of users See Available Months households, preferred licensees, and general licenses, which are lightly licensed. The incumbents are those who have historically held exclusive rights to the band, namely satellite earth stations and the U.S. Navy. Last year, priority licenses were auctioned off to allow licenses or under - specific counties to use the band as long as they do not interfere with the existing band and tolerate possible interference in the existing band. (Internet service providers such as Verizon and Comcast (Comcast) spent most of the money paid in the auction.) In general, authorized access allows users to use the bands as long as they do not interfere with the other two categories of users. Who will prevent interference? Sensor networks - environmental sensing capabilities (ESC) - detect CBRS use. Devices that want to use the CBRS bands first request a cloud-based spectrum access system (SAS) to reserve unused channels in a specific geographic area. If the channel is free, the SAS can grant the request. When a device that has been granted access to a channel has finished using it, the channel is put back into the pool from which the SAS can draw to grant further requests. How did the 3.5 GHz band become available? The release of the 3550-3700 MHz band stems from the FCC's release of the 2010 National Broadband Plan, which was intended to provide an additional 50MHz of spectrum for new mobile uses. the FCC targeted the 3.5 GHz band (referred to as the ""innovation band"") in rules released in April 2015 and reaffirmed those rules about a year later. rules. However, some details on implementation remain up in the air as operators disagree among themselves on some technical details - some smaller operators want the opportunity to expand their 5G coverage without purchasing fully licensed spectrum and therefore advocate allowing higher power access to points within CBRS, while larger The FCC has expressed interest in hearing full comments from both sides. Who will use this spectrum? Operators look to use it to expand the coverage and c...
