Allot MobileTrends Report Shows Significant 73% Growth in Global Mobile Data Bandwidth Usage in H2, 2010


Boston, MA - February 8, 2011 - Allot Communications
Ltd.<> (NASDAQ:
ALLT<>), a leading
supplier of service optimization and revenue generation solutions for fixed
and mobile broadband service providers worldwide, announced today that its
Allot MobileTrends
Report<> shows that
mobile data bandwidth usage continued its phenomenal rise with 73% growth
during the second half (H2) of 2010.  Video streaming continues to drive
this growth as it remains the fastest growing application type, accounting
for 37% of mobile bandwidth. Allot will be exhibiting at Mobile World
Congress from 14-17 February, in hall 2, booth B53.

The H2 2010 MobileTrends Report reveals that YouTube is responsible for a
tremendous 17% of mobile data bandwidth usage and continues as the single
most significant website for video streaming, accounting for 45% of total
video streaming traffic. The report also shows the continued exponential
growth experienced by social networking applications such as Twitter and
Facebook, which grew by 378% and 267%, respectively, underlining the natural
synergy that exists between social media and the mobile Internet.  The use
of VoIP and IM applications also continued to grow rapidly with an 87%
increase, demonstrating their ongoing appeal for subscribers.

This Allot MobileTrends Report also reveals that Google's Android Market
lags far behind Apple's App Store with only 9% of the overall app store
download traffic.  However, its rapid 177% growth rate may influence this
balance in the near future.

"Our MobileTrends findings demonstrate that mobile operators must understand
the value that over-the-top applications provide to users rather than just
focus on the amount of bandwidth they consume," said Rami Hadar, President
and CEO of Allot Communications.  "As networks move towards 4G/LTET and
convergence, understanding this value is likely to become even more critical
as operators will be expected to provide a more enriched and personalized
experience for their users."

Findings from the Allot MobileTrends Report also include:

.         YouTube remains one of the single most popular mobile Internet
destinations, accounting for 17% of mobile data bandwidth.

.         File sharing represents a significant 30% of mobile bandwidth.

 *   Apple's App Store is responsible for 89% and Google's Android Market
is responsible for 9% of overall app store download traffic.

.         Skype continues as the undisputed VoIP market leader, accounting
for 87% of mobile VoIP bandwidth.

2010 from leading mobile operators worldwide with a combined user base of
210 million subscribers. Allot gathered the data using the long term
reporting capabilities of Allot
