Industry Focus: Automotive
MHz frequency range, is primarily used by blue-light and military crews today owing to the high-voice quality and high secured transmission it offers. However, recent developments in wireless communication technologies have led to the increasing use of LTE450, which provides greater bandwidth while maintaining the same propagation characteristics essential for long-range communication.
The key to successful execution of critical operations is the use of both TETRA and LTE450, which necessitates the use of technologies capable of integrating both at the same time. Designed to be rugged and adaptable, and therefore perfect for mission-critical applications, new antennas like the SENCITY Road MULTI are now able to cover the 380-470 MHz frequency range, capable of providing a strong download link and a higher data rate. If additional capacity is required, modems can integrate an extra antenna connection. Through the connection of two antenna ports, greater performance and consistent communications can be achieved on the move, no matter the location or situation. Ideally, such installations will use antennas that provide multi elements within a single housing.
Enabling faster connections Key to future mobility concepts is the management of increasing traffic and the reduction of road incidents. This is where Cellular Vehicle-to-Everything (C-V2X) is playing a central role, connecting through cellular frequencies to improve overall road safety. To avoid collisions, low latency is key, and any information transmitted must relate to the location of vehicles that are moving within the same vicinity, in real time. The connectivity delivered through C-V2X can achieve this. 5G can underpin video surveillance and passenger information systems, increasing security and making roads safer for drivers. With the vast majority of current vehicles not
being equipped with modern 5G wireless systems, a major overhaul of existing infrastructure is required if C-V2X is to become a viable option. Solutions that can attach more antennas will be essential. Previously modems could typically utilise two
antennas for cellular connectivity, but the recent advancements now mean up to four need to be attached.
4X4 MIMO offers a number of major advantages to best support 5G network connectivity, producing a higher data rate for faster upload and download speeds, as well as redundancy. Antennas like the SENCITY Road MULTI have been designed
with these modems in mind and surpass consumer expectations where connectivity is concerned.
An evolving automotive landscape Advanced connectivity solutions hold the key to successful expansion and diversification within the automotive sector. The industry is experiencing rapid changes with the rise of diverse mobility, autonomous driving, electrification and connectivity, and all commercial vehicles can benefit from these trends so long as the right solutions are in place. Utilising one or a combination of the latest technologies in 5G, GNSS or Wi-Fi can not only vastly improve the connectivity available to vehicle users, but also general road safety, vehicle positioning, and many other transformative use cases. With the data exchange between vehicles, a truly connected system can be designed no matter if it is a bus, truck, agricultural vehicle, emergency vehicle, or a new form of commercial transportation coming to market.
