Operators will need the best possible selectivity and sensitivity in urban and suburban areas, as well as rural areas. ClearSite systems provide a solution to your networks' bandwidth problems. By improving SIR and BER, the ClearSite system allows 2.5G and 3G networks including EDGE, CDMA, and W-CDMA to increase bandwidth and approach Shannon's limit, as shown in the graphic above. Coverage has become a key issue in rural and suburban areas, as a result of the significant reduction in handset transmit power as users move to ultra-small portable phones, and make the transition from analog to digital. As a result, dead zones and coverage holes are common problems except for those carriers who have added large quantities of costly, long lead-time cell sites.
Coverage is also an important issue in urban areas.
In addition to outdoor coverage holes, in-building coverage is a chronic problem, as users attempt to use mobile phones indoors. It is particularly difficult in urban areas to deploy network enhancements that may improve one aspect of the network while at the same time degrading others. The improved receiver sensitivity that the systems provide eliminates dead zones and coverage holes, reduces dropped calls, and expands in-building as well as outdoor coverage. Series or parallel configurations are supported for maximum flexibility. All ClearSite systems include an automatic RF bypass switch in both main and diversity paths.
