Navini Networks was a company that developed an Internet access system based on WiMAX, which was subsequently acquired by Cisco Systems in October, 2007.
In January 2000, Wu-Fu Chen and Guanghan Xu formed Navini Networks and developed a wireless Internet access system. The company was based in Richardson, Texas and was privately funded by several investment-funds.
In 2001 it was awarded the 'Start-Up of the Year' award by KPMG and in 2002 it won some national and regional prizes. Between the formation and early 2003 it attracted $66.5 million from private investors and employed 130 employees.
When it was sold in October 2007 for $330 million to Cisco Systems, Navini had 70 customers. A Navini customer would be an Internet service provider providing wireless Internet access, mainly in areas where there are only limited wired alternatives available (such as Docsis access via a cable-TV network or DSL via the telephone network).
Navini developed a WiMAX wireless internet-access infrastructure consisting of two main parts: the central headend system with the special antennas and the RipWave modems or customer premises equipment
The Navini products offered a non line-of-sight wireless access system. The popular Wi-Fi systems require an unobstructed view between the antenna of the transmitter and the receiver for a good reception of the signals: when the view is obstructed the signal strength decreases and the reach of the signal is very small. By using a technique called spot beaming, normally used in satellite communications, it was possible to use radio-signals on frequencies that would normally require an unobstructed path between the transmitter and receiver or high-power transmitters.
A Navini system consists of one management-system, one or more base-systems and the user-modems or customer premises equipment
