How to Secure Wireless Communication Links for Public Safety? https://www.whwireless.com Estimated 8 minute to finish reading As the weather gets hotter, firefighting becomes a more important part of public safety. Because most fire departments cover large geographic areas and have growing populations, fire departments are responsible for large areas, including sparsely populated areas that lack cellular service. In order to respond to firefighting emergencies in a timely manner, fire departments need to enhance the signal of their wireless devices to ensure that reliable wireless connectivity is always available at the station and at the scene of an incident. In addition, they wanted to add failover capabilities to their mobile data coverage to maintain wireless connectivity at all times 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. Thanks to the antennas, which feature four ultra-wideband 5G LTE components, four WiFi 2.4/5.0GHz components and a high-performance GPS/GNSS antenna, HONGKEI provided them with 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, including 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 to support WiFi's MiMo/Split set operation, and an optional high-performance GPS/GNSS antenna with integrated 26dB gain LNA and high-quality filtering that delivers unmatched positioning accuracy. It can support the use of many terminals without the need for a metal grounding layer and maintains 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 engine, the fire department has ensured that any location in the area can have flexible wireless communications and seamless connectivity. They have also fed back that surrounding areas where connectivity was once not possible no longer have any issues and speeds are even higher than before across the district, which has greatly improved the efficiency and safety of the whole firefighting process. https://www.whwireless.com

Millimeter wave shielding test solution to help 5G millimeter wave communication https://www.whwireless.com Estimated 8 minute to finish reading The development of 5G technology has been extremely rapid in recent years, and it features high speed, low latency and large connectivity. The current 5G solutions are divided into millimeter wave and Sub-6GHz, except for Sub-6GHz which is now developing at a rapid pace, the progress of millimeter wave is also changing day by day. Millimeter wave, as the name suggests, is an electromagnetic wave with a wavelength between 1-10mm, and now it is no longer just at the research level, but is rapidly entering the commercial level and gradually covering the living periphery. With the popularity of 5G cell phones, we will find that the Sub6 crowded channel environment can no longer meet the user demand for high data volume and high speed, so the major cell phone manufacturers are gradually looking at millimeter wave. It can be said that millimeter wave is the direction of the next generation of cell phones, so as to meet the general public in the streaming media era for the increasingly high data transmission rate requirements. However, there are still some problems with the rapidly developing new 5G standard, millimeter wave is too "fragile" compared to Sub6, so it is easy to be blocked by the body, walls, clothes and even phone cases. Nowadays, there are more and more materials and styles of cell phone cases with the needs of the public, metal cases look beautiful, feel and heat dissipation, drop resistance, but easy to signal shielding problems, and with the widespread use of 5G, wireless charging and other new wireless transmission methods, this will become an urgent problem, the application of silicone, plastic, leather and other materials are gradually hot up. So how will these different material cases affect the phone's millimeter wave antenna? How to evaluate and select a suitable material for a 5G millimeter wave cell phone when it needs to be equipped with a cell phone case, which is an inevitable problem for cell phone design manufacturers, how to quickly and easily realize the barrier analysis of the material in the early stage, and how to efficiently and economically conduct sampling and verification in the production line? What means are available to analyze the millimeter wave blocking performance of various materials? The handheld millimeter-wave barrier test solution can complete the test of barrier materials anytime and anywhere, and can be adjusted according to demand, greatly reducing the time required for preliminary material testing, combined with the storage capacity of the device itself, only one test, one export, can directly realize the analysis and comparison of multiple materials, while ensuring the accuracy of the results can greatly save the engineer's time. It can save engineers' time while ensuring accurate results. In addition, it provides a modular millimeter wave barrier measur...

All-in-one antenna builds next-generation service network https://www.whwireless.com Estimated 8 minute to finish reading The new Emergency Services Network (ESN) is designed to improve public safety communications and is replacing the wireless voice broadcast services currently in use in the UK, with frontline users from police, fire and rescue, ambulance services as well as coastguard, local authority and utility services relying more heavily on access to the ESN. The primary purpose of ESN is to provide modern voice and data services nationwide, providing a reliable and secure mobile communications platform for all users.ESN will be implemented using the LTE cellular infrastructure owned and operated by EE, a major change from the currently privately owned 380-430 MHz TETRA network wireless service, which will initially provide resilient high-speed mobile broadband data and, in a later phase, plans to replace mission-critical voice functions with radio waves. As a result, there will be a period of time in the next few years when fleets across industries will require increasingly sophisticated antenna systems to ensure that reliable voice and data connectivity can be maintained during the transition phase of the wireless network, safeguarding efficiency while enabling the safety of personnel. ESN operates on EE's 4G network, which uses LTE technology in three frequency bands to provide mobile broadband bearers for data and mission-critical voice services. Widely used in public safety applications to provide voice and data communications, the GNSS series antennas provide efficient TETRA and high performance GPS/GNSS functionality in a compact housing and single-hole mount design. And to meet the need for additional connected devices in vehicles, the HK-GPSD Sharkee series antennas, which include GPS/GNSS, multi-band 2G/3G/4G/5G LTE cellular, dual-band WiFi, and external TETRA whips with a rugged single-hole mount shark fin housing design. MiMo is a key technology for delivering high-speed broadband, using multipath signal propagation to increase channel capacity. Typically 2x2 MiMo requires two antennas on the client side, but with the introduction of LTE Cat 18/20, a 4x4 MiMo antenna system with four antennas is required. MiMo systems require antennas with high isolation and low correlation coefficients, and all-in-one antenna solutions enable simple and effective antenna installation while meeting technical requirements. The antenna system is a key part of the ESN vehicle installation, providing a complete MiMo multifunctional antenna solution that is easy to install and provides predefined MiMo performance. In addition, a range of single transmit single receive (SiSo) multi-band cellular antennas are available as backup antennas to provide MiMo functionality alongside existing antennas when required. The new generation 5G antennas are capable of meeting ESN antenna specifications in all operating bands, using up to 5m of CS32 (LMR195 equivale...
