Redpine Signals has introduced a multi-protocol wireless solution with ultra-low power and a low cost designed to drive the emergence of the connected car. Redpine’s new WaveCombo solution 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’s wireless technology integration enables several applications and usage model 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 is a compact module (20mm x 23.9mm) and enables form-factor constrained applications.
V2X communication is an evolving market which needs a close partnership between the 802.11p technology providers such as Redpine Signals and car OEM solution providers like Mitsumi. We are happy to be a partner of Redpine and have been working closely with them to integrate their solution. Their unique wireless combination coupled with higher performance and lower power is ideal for the applications driving the adoption of 802.11p in the market.—Joe Pullin, Vice President of Global Marketing at Mitsumi Electronics
Redpine’s WaveCombo solution includes chipset, modules, IEEE 1609 software stack, stand-alone OBU, OBDII based OBU as well as an RSU. It can operate either in 802.11p mode or 802.11n/Bluetooth/802.15.4 mode. The module provides an output power of +23 dBm with Class C mask at 64 QAM. It also supports an extended temperature range of -40C to +105C critical for several applications. WaveCombo supports 5 MHz, 10 MHz and 20 MHz operations. It has <1ms switching time between control and service channels with a single module. Redpine provides OBU and RSU for field trials and enables tier-1 suppliers to create infrastructure products based on Redpine technology.
The WaveCombo solution also includes a software development kit (SDK) that includes two hardware boards for end to end testing with OBU and RSU reference designs. It embeds IEEE 1609 stack and SAE J2745 messaging along with all the necessary APIs for developing the applications. A few sample applications such as Emergency Electronic Brake Light (EEBL) have also been provided to assist in the development activity.
The WaveCombo chipset, module and IEEE 1609 stack are available now. OBU and RSU solution will be available by Sep 2016.California-based Redpine Signals is a fabless semiconductor, IoT devices and wireless system solutions company focusing on innovative, ultra-low
power and high-performance products for next-generation wireless applications. Redpine was founded in 2001 and was the first in the industry to launch an ultra low power and low-cost single-stream 802.11n chipset in late 2007.
In 2009, Redpine pioneered the adoption of self-contained 802.11abgn modules into the then emerging IoT market. In 2013, Redpine introduced the first multiprotocol wireless chipset for the Internet of Things market—featuring dual band Wi-Fi, dual-mode BT 4.1, and ZigBee.
Redpine has created multiple products based on this chipset including n-Link (hosted), Connect-io-n (embedded), WiSeConnect (advanced embedded secure) and WiSeMCU (MCU and multi-protocol wireless) modules.
