It is quite possible that 5G eventually swallows a large portion of the IoT and automotive markets as well. Such a broad reach would encompass multiple standards from low sub 700 MHz frequencies through to mmWave frequencies, such as 28 GHz and 60 GHz.
For example, the recently announced Qualcomm Snapdragon X50 will initially support operation in millimeter-wave spectrum in the 28 GHz band. It also employs MIMO antenna technology with adaptive beamforming and beam tracking techniques, which facilitates robust and sustained mobile broadband communications in non-line-of-sight (NLOS) environments. Bandwidth support up to 800 MHz enables peak download speeds of up to 5 gigabits per second.
However, the modem also supports LTE as Qualcomm see Gigabit LTE as an essential pillar for 5G, as it can provide a wide coverage layer for nascent 5G networks. LTE is also one means to addressing the IoT and automotive markets.
Recently, Telstra and Cohda Wireless successfully trialled Vehicle-to-Infrastructure (V2I) technology over Telstra’s 4G network in South Australia, a pivotal first step in developing Vehicle-to-Everything (V2X) technology.
Telstra believes its 4G and future 5G networks can play a vital role in supporting the faster rollout of intelligent transport systems and V2X applications, making implementation of the technology cheaper and more efficient. Telstra’s Director of Technology Andrew Scott said that the successful V2I trial marked the first phase of Telstra’s plan to show how V2X technology can be supported via Telstra’s 4G network.
However this is only the first phase of the project with additional trials lined up for testing Vehicle-to-Vehicle and Vehicle-to-Vulnerable (bicycles and pedestrians).
