Improving Grade of Service (GOS) While Reducing RF Channels Wireless service providers are adopting new deployment strategies to reduce network costs and improve quality of service. In one urban market, a major national wireless service provider has improved network traffic loading and significantly boosted network RF performance by centralizing radio equipment and deploying digital RF transport technology. The digital RF transport systems operate in simulcast mode and reproduce the signal at radiating points throughout the network. The new network architecture has produced trunking and channel re-use performance gains that enable the service provider to deliver greater GOS while reducing the number of RF channels | New Network Architecture Digivance Simulcast Networks Reduce Network Costs and Improve Quality of Service Digivance Simulcast Networks New Network Architecture Reduce Network Costs and Improve Quality of Service Improving Grade of Service GOS While Reducing RF Channels Wireless service providers are adopting new deployment strategies to reduce network costs and improve quality of service. In one urban market a major national wireless service provider has improved network traffic loading and significantly boosted network RF performance by centralizing radio equipment and deploying digital RF transport technology. The digital RF transport systems operate in simulcast mode and reproduce the signal at radiating points throughout the network. The new network architecture has produced trunking and channel re-use performance gains that enable the service provider to deliver greater GOS while reducing the number of RF channels. To achieve greater capacity with fewer RF channels network designers used two or more ADC Digivance digital RF transport systems operating in simulcast mode at radiating points throughout the network. This white paper describes that simulcast network architecture network traffic loading improvements and how the team determined the number of RF channels needed to achieve the desired GOS. New Network Architecture What is Simulcast A wireless simulcast communications system is defined as a signal or group of signals that is transmitted from a central transceiver and identically reproduced to several radiating points with all received signals from these radiating points sent for recovery at the central transceiver s receive circuitry. In the case of Digivance technology the central transceiver is the Base Transceiver System BTS Digivance host location and the several radiating points are multiple Digivance remote units as shown in this example of a Long-Range Coverage Solution LRCS simulcast deployment diagram ADC s patented Digivance digital RF .
