Redpine Signals offers Wi-Fi SiP modules

A Redpine Signals product story

Edited by the Electronicstalk editorial team Oct 22, 2008

Redpine Signals announced that it has released to market a set of three Wi-Fi SiP modules based on its ultra low power Lite-Fi 802.11n technology.

The modules offer a unique set of small form-factor and low-cost solutions for current and next-generation battery constrained mobile handsets, digital still cameras, consumer electronics devices and industrial data communications.

The modules offer a complete 802.11n sub-system, integrating Redpine's Lite-Fi RS9110 802.11n SoC, a RF transceiver, power amplifier, EEPROM and external front-end components.

They connect directly to an antenna on the line side, and to a host processor through a choice of SDIO, SPI and EBI interfaces.

Working off a single 3.3V power supply and a flexible reference frequency, the modules present unprecedented ease of integration and enabling low system cost.

The modules are accompanied by device drivers for Windows CE, XP and Linux operating systems.

The Windows CE drivers comply with Microsoft Windows CE 5.0/6.0 Test Kit (CETK).

The modules include high-performance host interfaces, including a SDIO interface that permits data throughputs of more than 30Mbps.

In addition, with the internal processor handling not only the WLAN protocol functions but also offloading cycle intensive layer-3 functions from the host (including TCP checksum and layer-3 security functions, such as 3DES, AES, RNG and SHA-1), the modules enable the provision of WLAN functionality with very little extra load on the host processor.

The modules also provide mechanisms that carry out fast roaming from one AP to another - even while in a network with enterprise mode security - allowing the seamless handover of voice calls throughout a large office.
