Backhaul Optimizer Claims to Double Bandwidth for Voice, Data

A new optimizer for mobile backhaul applications is said to double the amount of data standard networks can handle, allowing network operators to leverage existing networks for significant cost savings. The I-Gate 4000 from Dialogic Inc. (San Jose, CA USA) provides for voice- and data-stream optimization for 3G, 2G, and enterprise traffic, and is said to significantly improve the customer experience. The unit will be introduced at the upcoming Mobile World Congress In Barcelona.


A new optimizer for mobile backhaul applications is said to double the amount of data standard networks can handle, allowing network operators to leverage existing networks for significant cost savings. The I-Gate 4000 from Dialogic Inc.

The unit will be introduced at the upcoming Mobile World Congress In Barcelona.

The I-Gate 4000 optimizes voice packet streams in a number of ways, such as removing the “white space” that occurs during a conversation, thereby packing the voice stream more effectively. For data, the unit aggregates packet streams that have the same header and control information together, thereby combining them into fewer streams. According to Dialogic, the unit allows carriers to use existing infrastructure to carry twice the capacity (for example, 5E1s could handle traffic that had required 10E1s, saving the cost of leasing 5E1s).

The system already has its believers among telecom carriers. “We tested Dialogic’s solution both in the lab and in a field trial, and saw a significant bandwidth savings in our network,” said Cayetano Carbajo, Technology Director at Telefónica. “It delivers two-fold benefits — significant cost savings and growth opportunities for new subscribers.”

In order to maintain profitability, mobile operators need to minimize their backhaul network investment and operational expenditures (OPEX), all while expanding their network capacity. The I-Gate 4000 optimizes bandwidth to reduce OPEX transport requirements, and by doubling throughput over existing backhaul links, the solution should also reduce capital expenditures (CAPEX) by eliminating the need to purchase additional equipment.

Doug Sabella, President and Chief Operating Officer for Dialogic, said, “We understand the challenges service providers face and created a solution with their budget and time constraints in mind. We’re excited to deliver this solution to Telefonica and look forward to more successful deployments in the near future.”

The I-Gate 4000 supports a wide range of traffic types and interfaces, including IP- and ATM-based iub, Abis, Native IP, VoIP, PCM signals and Pseudowire (TDM over IP). Topologies for both Microwave and Satellite transmissions are also supported, including Point-to-Point, Point-to-Multipoint, Drop & Continue, Ring and Data Offload.
