Redpine enters M2M market with fully-featured Wi-Fi module

January 18, 2012 2 comments

Redpine Signals Inc. has entered the M2M (machine-to-machine) market with its first fully-featured Wi-Fi module. Let’s find out what the  Wi-Fi module is all about, and specifically, M2M!

According to Redpine, the M2M market is different from the traditional mobile and PC Wi-Fi market – in the sense that it requires ‘self-contained’ hardware and software. Traditional Wi-Fi implementations from other leading vendors who sell into PCs and mobile phones don’t meet this requirement since PCs and Mobile phones are equipped with strong host processors that do a bulk of the Wi-Fi processing.

Redpine is a pioneer in this market and was the first to announce a 802.11n Wi-Fi module, which was self-contained.  The ‘WiseConnect’ module builds upon its Connect-io-n product legacy and provides additional features like Wi-Fi Direct, enterprise security, SEP2.0 and embedded access point. Features supported and other capabilities include:

Self-contained: All hardware including antenna and crystal required for emissions certification (like FCC and IC) are integrated. All software required for Wi-Fi certification (like security supplicant) are included in the module. This makes the process of integrating the WiSeConnect module into an embedded system very easy.

Ultra-low power and high performance 802.11n: Single-stream 802.11n solution. Best-in-class transmit power of 18dBm and receiver sensitivity down to -98dBm, enabling excellent range. With shutdown power of less than 0.01mW, associated mode power of less than 3mW and active operational power of less than 30mW (UART 115K baud), the module enables ultra-low-power wireless battery operated applications.

Wi-Fi Direct: Wi-Fi Direct enables point to point link establishment without the necessity of connecting to an access point. With the prevalence of more and more smartphones and tablet PCs, it is desirable to directly interface the end-machines without going through the hassle of configuring and connecting to the AP (a.k.a bluetooth). Also, Wi-Fi Direct brings in a lot of power-save features that are desirable for the M2M sensor market.

SEP2.0: Integrating a high-energy home appliance or an in-home display or thermostat into the smart grid is made possible through the provision of SEP 2.0 communications in the WiSeConnect module.

Embedded AP: Provides an access-point functionality with limited number of stations (e.g., 8) for usage in embedded applications.

Host interfaces include SDIO, SPI, USB2.0 and Ethernet.

Commenting on the the future of Wi-Fi Direct, the Redpine spokesperson said that it is very bright. In addition, it is useful to note that all future Wi-Fi Alliance certifications like Wi-Fi Display have Wi-Fi Direct as a pre-requisite.

Finally, how is this solution going to benefit enterprises? He added that as an example, many hospitals have existing enterprise Wi-Fi networks used for intranet and Internet access. Wireless enablement of the medical devices has many advantages – for example it allows limited patient mobility while having all vitals streamed wirelessly to the monitors.

Secure streaming of data to and from a medical device to the servers and displays using enterprise security is enabled by embedding WiSeConnect modules into these devices. The advanced security features in WiSeConnect provides this and many other such benefits across multiple enterprises.
