5G Automotive & Aerospace
RF & Microwave Filter and Duplexer for 5G Automotive and Aerospace - Temwell Temstron
5G technology provides the intensive data in high-speed to support autonomous driving cars (self-driving), also lead a disruptive change in aerospace (aircraft communication & aviation). Because 5G characteristics can reliably transmit huge amounts of data at ultra-fast and with low latency. That is crucial to support, for instance, direct instant communication between the vehicles of the future, and drone widespread.
Automated cars must be aware of their surroundings. They must use built-in cameras and sensors, such as radio detection and ranging (Radar) and light detection and ranging (Lidar) technology that enable them to sense and interact with the environments around them and build on the information available from maps and GPS. Another important future development aim for autonomous driving is Vehicles must communicate with each other and with roadside infrastructure, as referred direct vehicle-to-everything (V2X) communication. However it is complex to process the plenty of information required for safe driving and meanwhile to communicate with other vehicles and nearby objects, including pedestrians and traffic lights.
3.4-3.8 GHz, 5.8-5.9 GHz spectrum has been allocated for globally dedicated to V2X communications, a lower carrier frequencies, such as the 700 MHz band designated for V2V communication in Japan. The following two common standard approaches are adopting:
★Dedicated short-range communications (DSRC) in United States, and Intelligent Transport System G5 (ITS-G5) in Europe are based on Wi-Fi protocol 802.11p.
★Cellular V2X technology (C-V2X) is a protocol that allows direct communication (not using mobile infrastructure). It is based on LTE now, but in the near future, it will be based on 5G standards.
With the help of 5G, Drone can operate through low level airspace. It can be piloted from any central location and by 5G internet connecting with aircraft sensors system in real time, which to support delivering multimedia input. In the future, Drone could be used to provide many services e.g. civil surveillance, deliver packages from distribution center to the client, and provide personal mobility services. The most commonly used frequencies for controlling drones (from ground to air) are the license-free radio bands: 433 MHz, 868 MHz, 915 MHz, 1.3 GHz, 2.4 GHz, 5.4-5.7 GHz and 5.7-5.8 GHz.
In order to realize air-based and ground-based 5G networks, aircraft communication and aviation devices (e.g. radar, detector, transceiver, ground stations) must be renew/upgrade and re-deployed where in airplane, airport, control tower, also involving telecom provider for 5G internet service (e.g. Wi-Fi). Aviation application primary band at VHF (72-88 MHz, 108-121 MHz, 128 MHz, 136-137 MHz, 156-157 MHz), UHF (328-353 MHz, 406 MHz, 960-1164 MHz, 1300-1350 MHz, 1435-1525 MHz, 1535-1660 MHz), SHF ( 2360-2395 MHz, 2700-2900 MHz, 4200-4400 MHz, 5000-5010 MHz, 5091-5250 MHz, 5350-5470 MHz, 8-9 GHz, 13 GHz, 15 GHz), EHF (32-33 GHz); Aircraft application band focus on VHF (121-123 MHz, 156 MHz, 161-162 MHz, 849-851 MHz, 894-896 MHz), UHF (1 GHz, 1.5 GHz, 1.6 GHz, 2.2 GHz, 2.3 GHz, 2.4 GHz), SHF (4200-4400 MHz, 4400-4940 MHz, 4825-4835 MHz, 5091-5150 MHz, 5150-5250 MHz, 5925-6700 MHz, 14 GHz) etc in United States, Canada, Mexico, Australia, South Africa and some countries in Europe.
