Redpine Signals announced the release of a self-contained, low-power Wi-Fi module for M2M markets. The WiSeConnect is said to be the first to implement advanced features like Wi-Fi Direct and Enterprise security required for 802.11n Wi-Fi based M2M connectivity. With all the hardware and software required for not only standards compliant Wi-Fi operation but also for regulatory certification, the module offers an easy path to integrating advanced wireless connectivity for the entire range of emerging M2M applications.
The new module includes an embedded processor along with Redpine’s ultra-low power 802.11n Wi-Fi subsystem, as well as an antenna and frequency reference to be fully contained. Apart from SDIO and SPI interfaces, the module provides Ethernet and USB interfaces for universal applicability. The module provides Wi-Fi Direct functionality – that allows other Wi-Fi Direct devices as well as standard clients to connect to it. It includes a full implementation of the SEP 2.0 software stack that enables emerging smart energy applications. In addition, it supports embedded AP functionality and in both client and access point modes, it offers WLAN enterprise security features.
Though self-contained, the module does not limit the achievable Wi-Fi throughput, thus enabling a larger range of applications. For example, users would connect printers or projectors wirelessly with their tablets or laptops – and the WiSeConnect module enables integration of Wi-Fi Direct capability into such devices with no additional load on its processor. As another example, integrating a high-energy home appliance or an in-home display or thermostat into the smart grid is made painless through the provision of SEP 2.0 communications in the module. For the industrial and medical arena, any kind of equipment can be easily connected to the corporate or hospital network with full enterprise level security using the new module.
The 35 x 22 mm device operates with a single 3,3 V supply and offers SDIO, SPI, USB and Ethernet interfaces. Variants include single-band 2,4 GHz and dual-band 2,4/5 GHz operation. The module is accompanied by small-footprint reference software running on the host system with examples that illustrate the simple-to-use wireless API. Evaluation boards are available.
