Reduce Costs for Inter-MSC Traffic

Reduce Costs for Inter-MSC Traffic

Your Needs
Reduce huge outlays in leased line circuits for long-distance inter-MSC connectivity

Our Solution
Inter-MSC (E channel) trunking is one of the main contributors to the cost of running a cellular operation. Typically, hundreds of long haul links are used to transport traffic between voice switches, in meshed, star or mixed network topologies. Reducing the number of links translates into immediate cost savings, adding directly to the mobile operator’s bottom line. Because the payload of inter-MSC transmission is voice traffic, the simplest and easiest way to realize this reduction is by compressing the amount of voice traversing the network using standard voice compression algorithms.

RAD’s Vmux/Gmux voice trunking gateways use standardized voice processing technology to compress a full E1/T1 circuit down to 128 kbps, or 16 full E1/T1 lines and associated signaling down to a single E1/T1 circuit over TDM or IP/Ethernet links.

Benefits

• Increase bandwidth utilization through up to 16:1voice compression
• Promote OpEx savings by reducing the number of required leased lines
• Support and optimize all types of signaling channels
• Enable transparent traffic delivery over packet with pseudowire encapsulation
• Small, scalable and easy to install
• Future-ready to support softswitch-based, NG mobile core

Mobile Backhaul over Wireless Radio

Mobile Backhaul over Wireless Radio

Your Needs
Enable quick deployment of mobile backhaul connections using point-to-point wireless radio, to cost-effectively deliver cellular traffic with carrier-grade reliability.

Our Solution
RAD’s Airmux-200 and Airmux-400 are broadband wireless multiplexers for mobile backhaul over wireless radio, delivering unframed E1 or T1 and Fast Ethernet traffic with a total air interface throughput of 48 Mbps or 50 Mbps. The Airmux mobile backhaul wireless multiplexers ensure service availability by complying with stringent latency, delay variation, and clocking accuracy requirements for voice transmissions. A virtually maintenance-free wireless solution, the Airmux support a range of up to 80 kilometers (50 miles) or 120 kilometers (75 miles) between cellular base stations and their controllers, providing high reliability at a fraction of the cost of leased lines or satellite links.

Benefits

• Reduce operating expenditures and facilitates quick deployment of new cell sites
• Support license-exempt sub-6 GHz radio bands
• Allow traffic delivery of management and control signals via Fast Ethernet interfaces
• Enable easy service extension to rural or remote regions
• Provide carrier-class performance and reliability with high link availability and redundant power supply
• Guarantee over-the-air traffic protection with enhanced security mechanisms and a 128-bit encryption key

Mobile Backhaul over SHDSL

Mobile Backhaul over SHDSL

Your Needs
Utilize SHDSL infrastructure for mobile backhaul to reduce Last Mile transport costs and to connect to new packet-switched networks.

Our Solution
RAD’s ACE-3105 cell-site gateway and ACE-3220 cell-site gateway enable mobile operators and transport providers to substantially reduce backhaul costs by leveraging wholesale SHDSL deployments and widely available ATM and IP DSLAMs to carry GSM and UMTS traffic over ATM, PSN or hybrid transport networks. In addition to allowing mobile backhaul over SHDSL or G.SHDSL.bis links, the ACE-3105, ACE-3205 and ACE-3220 also incorporate pseudowire encapsulation support, as well as high precision clock recovery capabilities. These ensure accurate delivery of symmetric services including real-time voice and high-priority applications, over asynchronous packet transport networks.
Using IMA or physical (M-pair) bonding schemes, the ACE-3xxx combine up to four SHDSL or SHDSL.bis pairs into a single data stream, with a combined data rate of up to 9.2 Mbps or 20 Mbps, respectively.

Benefits

• Reduce OpEx by using ubiquitous, low-cost copper infrastructure
• Enable longer reach and higher bandwidth through bonding
• Support service differentiation with QoS capabilities
• Interoperable with all major DSLAMs

Migrating to LTE and all-IP mobile backhaul

Migrating to LTE and all-IP mobile backhaul

Your Needs
Reduce mobile backhaul costs for existing 2G, 3G and HSPA traffic while ensuring an economical migration to LTE and all-IP backhaul.

Our Solution
RAD’s best-of-breed cell-site demarcation gateways enable carriers, mobile operators and transport providers to gradually migrate their multi-generation radio traffic to an all-IP mobile backhaul network, lowering their transport costs while enabling new LTE services. The future-proof cell-site demarcation gateways are deployed at the cell-site to backhaul 2G, 3G and HSPA traffic over packet transport, easily supporting increased traffic volumes from new mobile applications without device upgrades. When LTE is introduced, the cell-site demarcation gateways easily handle eNodeB traffic, supporting both S1 and X2 interfaces along with end to end OAM capabilities over MPLS or Carrier Ethernet.

Benefits:

• Comprehensive pseudowire functionality with advanced synchronization capabilities
• Scalable solution from a few Mbps per cell site up to 1Gbps
• Interoperability with central-site mobile backhaul aggregation equipment from RAD and other vendors
