The UBX-P3 is a compact Wi-Fi chip that provides 802.11p functionality for V2X applications. It operates on both 5.9 GHz and 760 MHz frequency bands. This chip is fully compliant with IEEE WAVE, ETSI V2X, and ARIB T-109M requirements and enables concurrent reception on two 802.11p channels. The UBX-P3 provides an output power of -3 dBm with data rates of up to 27 Mbps (10 MHz channel) and 54 Mbps (20 MHz channel). It has a receiver sensitivity from -100.2 to -98 dBm. It also supports diversity in both transmit and receive directions, thus providing full coverage around the vehicles.
This UBX-P3 chip measures 9 x 11 x 1.04 mm and features an Ethernet host interface, which allows maximal flexibility in placing the chip in a vehicle, independent of the distance from the host processor. Its compact and robust design makes it an ideal solution for operation in harsh environments. The V2X module requires 3.3 V of supply and consumes less than 1W of power.
