How can carriers in sparsely-populated countries plan and implement a nationwide deployment of broadband IP and new mobile services?
The integration of newer data-hungry packet-switched services, which increase bandwidth demand significantly, poses a special problem for such countries which until now have depended on legacy SDH/SONET and PDH infrastructure.
In cities, such new services can be delivered over increasingly popular Metropolitan Area Networks (MANs). From there they have to be transported over great distances to peripheral and rural areas. Beyond the reach of fiber, carriers prefer to use existing PDH or SDH/SONET networks to avoid the high cost of deploying Next Generation alternatives. The challenge is in delivering new services even beyond the reach of those PDH/SDH/SONET lines. One solution is to backhaul them over WiMAX and CDMA (EVDO).
A highly effective way to provide this connectivity is by deploying Ethernet access solutions from RAD Data Communications.
The RAD solution begins with its Egate-100 Gigabit Ethernet over TDM aggregation gateway, which hands off traffic from the Metro Ethernet cloud to the SDH/SONET network. From there the traffic is transmitted to WiMAX antennas using a RICi-16 Ethernet over bonded PDH network termination unit (NTU) or a RICi Ethernet over E1/T1 NTU to every last customer premises beyond the reach of traditional landline infrastructure.
For their part, mobile operators can make use of this very same infrastructure to transport their own 3G services to their remote base stations and Node Bs. In this scenario, RAD’s Optimux series of fiber optic multiplexers would transmit the BTS traffic over point-to-point fiber and the existing SDH/SONET backbone.

RAD’s RuralSuite portfolio for rural mobile backhaul is designed for isolated regions with small numbers of potential subscribers that, until now, have gone without mobile coverage because of the absence of the necessary infrastructure that would be required to connect them to nationwide networks. In such situations, RuralSuite’s field-proven, cost-effective solutions extend mobile coverage not only over fiber but also copper or wireless links, over either point-to-point or point-to-multipoint topologies. What makes RAD's offering unique is that it includes a full gamut of affordable, globally tested solutions that can quickly be deployed to backhaul mobile traffic over any type of infrastructure and topology.
Besides its Optimux fiber optic multiplexers, the other RAD solutions that comprise the RuralSuite product portfolio are the ASMi-54 SHDSL.bis modem with an integrated router or multiplexer and the Airmux line of broadband wireless multiplexers.
