Aperto Networks in Alpha Trials

MILPITAS, Calif. -- Aperto Networks, a developer of second-generation fixed broadband wireless access systems, has announced its first alpha trial in a northern California carrier network. Aperto's system has been installed by a wireless Internet service provider using 5 GHz U-NII frequency system. Testing includes real-world conditions such as variable equipment configurations, line-of-sight (LOS), obstructed line-of-sight (OLOS) and non-line-of-sight (NLOS) locations, light-to-heavily loaded network traffic, symmetric voice, data and video transmissions, and veriable cell radii.

Aperto's system uses adaptive Time Division Duplexing (TDD), which is well suited for unlicensed band deployment because it provides the flexibility to operate in a single 6 MHz channel anywhere in the spectrum with data rates up to 20 Mbps. The companies multi-service solution uses Rapidburst TM, Aperto's next generation dynamic TDMA protocol, with embedded QoS and prioritization provisions, that enables the upstream and downstream bandwidth allocation to be dynamically adjusted to accommodate changes in traffic patterns. This leads to dramatically improved performace in a heavily loaded system.
