Unique Value in DAS deployment
•
Central processing facility contains standard IT equipment
– Servers, routers, ethernet
– Reduced CAPEX, reduced maintenance
•
Signal is converter from digital to RF once, at the radiating point
– No translation loss, reduced cooling requirements
•
Network between processing and Radiating Points
– Allows carriers and frequencies to be dynamically assigned
– Improved capacity and frequency management
•
Multiple standard support
– Additional standards are software upgrades to the servers.
– Only need new hardware in two cases:
• If new spectrum is licensed, a new RF head for the band is required
• Additional capacity is obtained through adding servers

Open Interface Management
•
Advantages
•
Web based
•
Easy to use
•
Enables ongoing
optimization of network
•
SNMP Compliant

Software Radio OPEX Savings
•
Site Rental and Utilities
•
Maintenance / Upgrades
•
Backhaul
Note: CAPEX savings 5%-25% depending upon configuration
(i.e. number of TRX’s, power per carrier)

Summary
•
Software Radio Infrastructure is here today
– FCC approved
– Live GSM/GPRS operation with Mid-Tex cellular; roaming with Cingular
– Additional standards under development
– Demonstrated in Military Applications
•
Deployments
– Initial deployment benefit carriers in traditional deployments
– Enable evolution to more spectrally efficient architectures (DAS)
•
Long Term
– Once infrastructure is in place, carriers can leverage flexible spectrum
