Convergence

Bandwidth optimization solutions from Celtro maximize backhaul network efficiency and flexibility in 2G, 3G, converged, or satellite-based networks - improving service delivery, reducing network CapEx and OpEx, and raising subscriber satisfaction.

• Backhaul Convergence - optimal transport convergence of 2G, 3G, and WiMAX traffic
• 2G Networks - enhance mobile backhaul performance in 2G networks
• Satellite - optimizing satellite-based mobile backhaul networks

Optimal Convergence

Celtro's innovative mobile backhaul solutions provide optimal transport convergence for 2G, 3G, and WiMAX traffic to maximize backhaul network efficiency and flexibility and reduce network expenses.

How does it Work?

Celtro's unique Optimal Convergence starts with optimization of different traffic types by eliminating idle and redundant parts, leaving only the actual information a variable bit rate format. The flows of information are packetized into ATM cells or MPLS packets, in accordance with backhaul aggregation technology. All 2G, 3G, and WiMAX service flows are statistically multiplexed to maximize statistical gain and dynamically share the backhaul resources based on QoS prioritization. This dynamic sharing renders the backhaul network transparent to variations in traffic demand between different mobile services, and to customer and traffic transition from 2G to 3G. It also enables rapid and cost-effective introduction of mobile broadband services without heavy investments in new infrastructure.

Benefits of Celtro Optimal Convergence

• Higher network efficiency, greater capacity delivery through traffic optimization, and statistical gain for both 2G and 3G traffic
• Rapid introduction of data services and better service delivery based on dynamic sharing of backhaul resources by all services
• Reduction in network operational costs owing to increased efficiency and the use of a single unified backhaul network rather than multiple overlaid networks

Optimizing 2G Network Performance and Costs

GSM networks and the services they provide continue to play a predominant role in the mobile world. Innovative backhaul solutions from Celtro enhance mobile backhaul network performance in 2G networks - opening up the backhaul network and reducing network CapEx and OpEx.

How does it Work?

The Celtro solution aggregates and optimizes 2G backhaul traffic, grooming 2G TDM traffic at the 64Kbps level, and optimizing groomed traffic with gains of up to 3:1 for Abis traffic and up to 2:1 for Ater traffic. Leveraging unique patented optimization algorithms, Celtro eliminates traffic redundancies - idle frames, silent frames, and constant patterns in voice, data and signaling traffic. Actual relevant information is classified as voice, data and signaling support and packetized into layer 2 packets. Traffic is statistically multiplexed at output buffering, and the optimized traffic terminated at the receiving end, regenerating the original non-optimized flow.

Benefits of Celtro 2G Traffic Optimization

• Better backhaul performance, more capacity over existing infrastructure
• Rapid service introduction with guaranteed Quality of Service (QoS)
• Saves on network OpEx and CapEx, optimizing existing infrastructure

Optimizing Satellite-Based Mobile Backhaul Networks

Operators serving remote regions often base backhaul expansion on the adoption of VSAT (IP-based, point-to-multipoint) satellite networks. Due to steep transmission costs, these solutions require highly efficient conversion of GSM traffic into IP-based traffic, prioritization of different traffic types sharing the same media, and accurate synchronization of base stations. Celtro's optimization solutions reduce satellite link (space-segment) leasing costs – delivering optimum call/Kbps bandwidth ratios and enabling mobile operators to migrate to 3G services using VSAT.

How does it Work?

Operators can deploy Celtro's solutions in rural and remote locations and at VSAT hub sites. Celtro offers efficient and dynamic bandwidth consumption, excellent QoS handling, and efficient management of shared media - identifying and mapping traffic types into differentiated priority queues and correlating QoS marking. Celtro solutions ensure priority forwarding of signaling information - protecting the network from BTS resets, and enabling the operator to provide bandwidth-on-demand (BoD) applications.

Benefits of Satellite-Based Mobile Backhaul Network Optimization

• Lowers bandwidth consumption in the costly satellite link
• Maximizes point-to-multipoint satellite link efficiency, providing traffic optimization, traffic-type QoS differentiation, and precise synchronization
• Lowers satellite capacity leasing costs
