Bharti Airtel Limited is a leading integrated telecommunications company with operations in 20 countries across Africa and Asia. Headquartered in New Delhi, India, the company ranks amongst the top five mobile service providers globally in terms of subscribers. In India, the companys product offerings include 2G, 3G and 4G services, fixed line, high-speed broadband through DSL, IPTV, DTH, and enterprise services including national and international long distance services to carriers. In the rest of the geographies, it offers 2G, 3G mobile services.
More than one billion people reside in Africa. Airtel entered the region with a clear intent and strategyto transform how individuals communicate and how communities interact in the region. The low mobile penetration levels across many of the African countries of operation presented an opportunity for this service provider. However, managing operations in 17 countries with different levels of infrastructure, a variety of terrains, varying population density and changing availability of resources is a complex task.
In Africa, Airtel is a major consumer of satellite capacity, particularly in landlocked countries without direct access to submarine cable capacity. In order to enable sustainable and profitable service expansion and subscriber growth to rural areas and remote villages, Airtel needed to upgrade its satellite-based network infrastructure.
Bandwidth Optimization
CDM-625 Advanced Satellite Modem with DoubleTalk® Carrier-in-Carrier®
Airtel selected Comtech EF Datas CDM-625 Advanced Satellite Modem with DoubleTalk® Carrier-in-Carrier® bandwidth compression to optimize their satellite links and to better leverage available bandwidth.
Memotec CX-U Series
The CX-U Series brings together a flexible access device and mobile backhaul traffic optimization, offering a variety of backhaul interfaces and transmission options. Airtel selected several CX-U models for deployment in AfricaCX-U 1010, CX-U 1220 and CX-U 1240. The products are optimizing Airtels Radio Access Network (RAN), significantly reducing the amount of backhaul bandwidth required to support their mobile services over constrained links.
Bharti Airtel completed the first phase of their network upgrade. By using the Comtech EF Data and Memotec bandwidth optimization technologies, they have successfully reduced network operating expensesfor some satellite links by as much as 50 percent.
As traffic and subscriber demand increases, Airtel is prepared to cost-effectively expand services while maintaining the quality of service their users have come to expect.
The combined Comtech EF Data and Memotec mobile backhaul solution enables sustainable and profitable service expansion for mobile operators, including:
– Expansion into low density regions
