Less interference in 5.8 GHz band – When calculating the link budget, 2.4 GHz has 7.7 dB advantage compared to 5.8 GHz. This means that 2.4 GHz signal can propagate >2 times distance than 5.8 GHz signal under same conditions. However, the reality is that too many devices are working in 2.4 GHz band and interfering with each other, which dramatically reduces the range.
High-velocity tolerance – Consumer drones will cross the 100 km/h barrier soon, which will certainly introduce challenges to the communication system. 802.11p product can perfectly solve this issue, since it is designed to support high-speed vehicles. The solution from NXP has been proven to sustain with relative speeds up 500 km/h.
Affordable solution – Most development costs of V2X system for drones have already been addressed by the automotive industry, such as developing a new standard and a chipset, field tests. Moreover, the cost will drop down further with the V2X market growth.
The NXP 802.11p solution is cost-effective and meets all key requirements of drone video transmission. It outperforms Wi-Fi in several key specifications and provides the state-of-the-art performance.
