Recognizing G2 Microsystems unique offering and its alignment with the customers of Roving Networks,
Roving acquired G2 in April 2010.

G2's silicon is configured into three distinct domains. As expected there is an RF domain used when actual Wi-Fi related communication is required, next to that is the digital domain comprising of a 32 bit RISC microcontroller and true 802.11 b/g MAC*. Finally, the silicon offers a third domain controlled/monitored by a programmable state machine. This third domain can remain awake while the rest of the system sleeps. This domain can be programmed to wake the other regions depending on certain conditions that may occur on any of its 10 I/O, 8 ADC's (14 bit), RFID reader, MAG reader or timers.

The G2 silicon is supported by Roving's in house API called 'WiFly'. WiFly allows access to many of the features available in the G2 silicon without the need for customers to manipulate registers within the chip. The API provides a very simple interface for the customer, functions that may call on many register updates can be called in a simple command; example 'scan'. The Scan command automatically checks for any access points available on the available W-Fi channels, more information on the WiFly API can be found in the WiFly user guide.

*(Note: Often Wi-Fi vendors will claim a `b` rate radio to be `b/g` compatible, but this is not true and data rates can only reach a maximum of 11Mbit/s restricting the network, G2's solution offers up to true `G` rates without hindering network speeds)

Wi-Fi Protected Setup enables typical users who possess little understanding of traditional Wi-Fi configuration and security settings to automatically configure new wireless networks, add new devices and enable security.

Users of home and small office networks need access to the highest available security mechanisms, and they need to be able to make simple additions and changes to the connected equipment without access to a technical support group. Wi-Fi CERTIFIED Wi-Fi Protected Setup™ offers users incomparable ease of use in setting up small Wi-Fi networks that operate at the highest levels of security available in equipment today - with a simple, almost totally automated setup process that can require as little interaction as the push of a button.

Wi-Fi Protected Setup provides an industry-wide mechanism to set up and configure networks for home and small office (SOHO) environments. Wi-Fi Protected Setup enables typical users who possess little understanding of traditional Wi-Fi configuration and security settings to easily configure new wireless networks, to add new devices and to enable security. Products that are Wi-Fi CERTIFIED™ for Wi-Fi Protected Setup have been on the market since 2007.

The Wi-Fi Alliance has enhanced the Wi-Fi Protected Setup program with new features that improve usability and lead systems to the highest level of security protection available in the equipment in use.
