Motorola had a minority equity investment in Orthogon through its venture capital arm, Motorola Ventures, and has distributed Orthogon's products through Motorola's Canopy business since 2004.
Terms of the transaction were not disclosed. The acquisition is expected to close in the first half of 2006.
Orthogon has expertise in intelligent OFDM-based, wireless IP, point-to-point transmission networks. Of particular interest are Orthogon's software-defined Ethernet bridges. Motorola said Orthogon's expertise in wireless Ethernet connectivity is highly strategic to its wireless broadband business.
Orthogon's systems are deployed around the world. Installations include the cities of Torrance, Calif. and Poughkeepsie, N.Y., and the 4 Seasons Cooperative in South Dakota.
The acquisition will expand Motorola's MOTOwi4 portfolio wireless broadband technologies, which include WiMAX, Mesh Solutions and Canopy products.
