Gilat hosts free webinar on satellite-based cellular backhaul solutions

Gilat Satellite Networks is inviting mobile network operators to a free live webinar solutions on April 17, 2013 at 13:00 GMT. The webinar will discuss how broadband satellite-powered cellullar backhaul solutions can extend mobile connectivity.

According to Gilat, satellite backhaul solutions can bring mobile networks to remote areas; increase subscriber bases; and fulfill requirements for bandwidth, budget, and network architecture, all while complying with government regulations.

The Gilat free webinar will discuss access schemes that support both small cells and large macro cells, reduction of OPEX through maximum bandwidth efficiency (TDMA,) dedicated channels for high throughput (SCPC,) and support for heterogeneous networks like 2G, 3G, and LTE. All of these can extend mobile connectivity using satellite broadband technology.

Comtech subsidiaries gets $1.7M equipment order from Asian mobile operator

Comtech Telecommunications Corp. announced yesterday that an Asian mobile network operator placed a $1.7 million equipment and optimization order with its Arizona-based subsidiary, Comtech EF Data Corp.

The mobile operator is planning to upgrade and expand its satellite-based mobile backhaul network using Comtech EF Data's Modems and RF Products. It will also procure RAN Optimization from another Comtech TC subsidiary, Memotec.

The Asian mobile operator will install the proven combination of Comtech EF Data's CDM-625 Advanced Satellite Modems and Memotec's CX-U Series RAN Optimization at new sites. Existing sites will also be upgraded with the new Comtech equipment to best optimize their network.

Comtech's CDM-625 Advanced Satellite Modem blends advanced forward error correction and bandwidth compression as provided by DoubleTalk(R) Carrier-in-Carrier(R.) DoubleTalk(R) allows a duplex link's transmit and receive carriers to share the same transponder space. These synergized technologies will help users minimize operational and capital expenditures by maximizing throughput/availability without the need to purchase and power additional transponders.

The CX-U Series combines the roles of a flexible access device and mobile backhaul traffic optimization. It offers a staggering range of backhaul interfaces and transmission options which includes Abis/Ater optimization, 2G/3G aggregation, DCME voice trunking optimization, TDM Pseudowire, all-over-IP, Frame Relay, or MLPPP protocol support.

Because of the CX-U's versatility and the critical role it plays in optimizing its mobile backhaul network, the Asian mobile operator decided to order several models -including the CX-U 1010, 1220 and 1280- to achieve a superb mix of access and optimization services.

In addition, Comtech's customer procured both indoor and outdoor models of Comtech EF Data's frequency conversion RF Products. The LPOD Block Up Converter, UT-4505 Up Converter, and the DT-4503 Down Converter will provide frequency conversion for outdoor environments. The rugged LPOD is weatherproof and designed to withstand harsh conditions, while the UT-4505 and the DT-4503 units can be mounted on a rack and are considered to be the end-all of high-performance and cost-effective frequency converters.

Comtech's new customer is the latest in a long list of similar companies and service providers around the world that have widely adopted Comtech's market-leading satellite communications solution featuring the CDM-625 modem and CX-U Series Double Talk(R) Carrier-in-Carrier(R.) The Comtech combination has been proven time and time again to deliver quality transmissions at a cost-efficient rate.
