WaveCombo™ Solutions

WaveCombo in an integrated, multi-protocol wireless solution with ultra- low power and a low cost designed to drive the emergence of the connected car. It combines 802.11p. 802.11abgn, Bluetooth 4.0 Dual mode (classic and low energy) and 802.15.4/ZigBee into a single solution. It enables 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 is a complete end to end V2X solution including the following:

  • Chipset with 802.11p, 802.11abgn, Bluetooth 4.0 Dual Mode, 802.15.4
  • Integrated module with all front end components and power amplifier
  • IEEE 1609 Stack, ETSI ITS-G5 Stack*
  • On-Board Unit *(OBU) for test deployments
  • Road Side Unit* (RSU) for test deployments
  • Software Development Kit for developing DSRC and non-DSRC applications (sample applications are provided with the kit)

WaveCombo’s unique wireless technology integration enables several applications and usage models such as emergency vehicle approaching warning (using 802.11p and BT), roadside alert (using 802.11p and BT), smart cone for worker safety (using 802.11p and 802.15.4) and passenger hot spot (802.11p in motion and 802.11n when parked) without the need for adding additional wireless modules.

WaveCombo Chipset and Module

WaveCombo chipset (WCMBA1) provides a unique combination of 802.11p, 802.11abgn, Bluetooth 4.0 dual mode and 802.15.4 which reduces the time to market and cost of connected car applications. It also includes an embedded processor with rich set of peripherals offering minimal load on the host processor. Redpine also offers a module, WCMBA1-NBZ-D0P based on this chipset. The module includes the MAC Layer, PHY Layer, 2.4/5 GHz RF transceiver and a power amplifier. It 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 has a compact form factor (20mm x 23.9mm) and enables form-factor constrained applications. It can be used for Road Side Unit (RSU) as well On Board Unit (OBU).

Here are some salient features of the module:

  • Operates in 802.11p or 802.11abgn/Bluetooth/802.15.4 modes of operation
  • Supports SDIO and USB host interfaces
  • Supports two antennae for antenna diversity
  • Provides < 1ms switching time between Control Channels (CCH) and Service Channels (SCH)
  • Configured to be used in RSU or OBU
  • Output power of +23 dBm (+/-1 dBm) at 64 QAM with Class C Mask
