WaveCombo Module

WaveCombo module is a multi-protocol wireless solution for the Connected Car (V2X) market. It integrates 802.11p, 802.11abgn, Bluetooth Classic, Bluetooth Low Energy and 802.154/ZigBee in a single module. The module can be used in either 802.11p mode or 802.11n/Bluetooth/802.15.4 mode with an application layer switching between the two modes. The module includes the MAC Layer, PHY Layer, 2.4/5 GHz RF transceiver and a power amplifier. It also includes an embedded processor with rich set of peripherals offering minimal load on the host processor. The module connects to the host processor through SDIO or USB interfaces. WaveCombo is a compact module (20mm x 23.9mm) and enables form-factor constrained applications.

WaveCombo module can be used for dedicated short range communications (DSRC) as well as non-DSRC applications while also featuring low power consumption ideal for use in bicycles, helmets, smart phones, and any such non-vehicular applications for rider as well as pedestrian safety. WaveCombo can be used in Road Side Units (RSUs) as well as On-Board Units (OBUs). Redpine provides a complete IEEE 1609 stack* and SAE J2735 that works with the WaveCombo module. Redpine also provides a software development kit (SDK) which enables the developers to test the module and develop their applications.
