TEMPE, Ariz. & NAIROBI -- December 18, 2012

Bharti Airtel (“Airtel”), a leading telecommunications services provider with
operations in 20 countries across Asia and Africa, and Comtech EF Data
Corporation celebrate the Best Backhaul Solution for Africa at the 5^th annual
AfricaCom Awards ceremony in Cape Town, South Africa. The AfricaCom Awards
reward excellence in African telecoms, media and ICT. The Best Backhaul
Solution for Africa Award recognizes a fiber, satellite or wireless solutions
provider that significantly improved backhaul capacity with measurable
improvements in quality and reliability of service in Africa.

Comtech EF Data was selected by the panel of judges for its role in supporting
Bharti Airtel’s satellite-based network upgrade and service expansion across
its operations in 16 African countries, which is one of the largest backhaul
upgrade projects for the African continent. In order to enable sustainable and
profitable service expansion and subscriber growth to rural areas and remote
villages in Africa, Bharti Airtel needed to upgrade its satellite-based
network infrastructure. Bharti Airtel selected the Comtech EF Data satellite
mobile backhaul solution to transport and optimize voice and data
communications and to facilitate significant growth planned for the region.

Comtech EF Data’s award-winning CDM-625 Advanced Satellite Modem with
DoubleTalk^® Carrier-in-Carrier^® bandwidth compression and the CX-U Series by
its subsidiary, Memotec, were selected by Bharti Airtel. DoubleTalk
Carrier-in-Carrier, based on the patented “Adaptive Cancellation” technology,
allows transmit and receive carriers of a duplex link to share the same
transponder space. DoubleTalk Carrier-in-Carrier is complementary to all
advances in modem technology, including advanced forward error correction and
modulation techniques. This allows for its successful deployment in
bandwidth-limited and power-limited scenarios, as well as reduction in earth
station BUC/HPA power requirements.

The Memotec CX-U Series is a dedicated mobile backhaul platform delivering
Radio Access Network (RAN) optimization, A/E voice trunk compression and TDM
Pseudowire. Bharti Airtel deployed several CX-U models, which are now
optimizing the RAN and significantly reducing the amount of backhaul bandwidth
required to support mobile services over constrained links. The combination
Comtech EF Data and Memotec mobile backhaul solution is deployed globally by
the top mobile network operators.

“We are honored to be the recipient of this esteemed award and to receive
recognition of our significant contribution to backhaul connectivity in
Africa,” commented Daniel Enns, Senior Vice President Marketing and Business
Development for Comtech EF Data.

By utilizing Comtech EF Data’s bandwidth optimization technologies, Bharti
Airtel reduced overall satellite transponder consumption from 17 to 12, and
successfully reduced network OPEX for some satellite links by as much as 50%.
Additionally, Bharti Airtel increased coverage in rural areas and was able to
offer services to end users with no degradation in quality.

“We congratulate Comtech EF Data on this achievement,” said Eben Albertyn,
CTO, Airtel Africa. “Their solution is instrumental in our providing
best-in-class mobile services to Africa.”
