Business Opportunity

Wireless Operators are launching data services

Widespread deployment in 2005

Coverage shrinkage due to high demands of data applications High dropped call rates and access failure rates are not acceptable High mobile transmit power requirement reduces capacity and speed

Link Optimization

RF Link is the signal to and from the mobile to the base station.

ISCO optimizes the processing of that signal with products and services that

Improve signal reception and transmission Mitigate Interference

Recover cell site capacity and coverage; improve call quality with fewer dropped connections => build customer satisfaction

ISCO improves network performance
