Technology Description

The innovation is a multi-radio single-core/dual-core radio chip device for 3G-4G wireless markets with applications for Femtocells. The Femtocells are the micro base stations targeted for small-medium enterprises, residences and hotspots in 2011 and beyond time frame.

The architecture of the radio chip allows for LTE, WiFi, or both (WiLTE) radios to be combined on a single chip, allowing for core code re-use and a reduction in silicon. WiLTE allows both radios to be managed and switched without dropping a call. Using Femtocells with LTE and WiFi communications will allow hand held devices to use WiFi for the 'last mile' connectivity. This can boost their cellular signal, or provide a signal where none currently exists, such as in rural or other remote areas. The device also allows for multiple callers within the home (or local area) to connect through one Femtocell connection.

Potential Benefits

The greatest benefit of this technology is the innovation of its architecture. Placing both LTE and WiFi soft cores on a single chip saves switching overhead and power, and reduces the amount of silicon necessary to manufacture the chip. Manufacturers can choose LTE, WiFi, or WiLTE depending on the purpose of the device the chip will be used for.

The footprint is small and performance is greatly enhanced. Because LTE and WiFi are both IP based signals, the combo chip design is preferred and will allow for 30% or more core module re-use. In addition to switching efficiencies, this will also provide the flexibility necessary to continue innovating new features, more intelligent network switching and routing, etc. which could mean additional patent filings. Cellular traffic can be offloaded to the WiFi network, reducing the amount of bandwidth necessary."
