VectaStar Radio Controller Launched to Deliver Ultra-high Capacity and Low Latency Performance

CAMBRIDGE, England, February 8, 2011 - Cambridge Broadband Networks Limited
today launched its 10Gb/s multipoint microwave backhaul platform. VectaStar
Radio Controller (RC), the latest development of the company's VectaStar
microwave backhaul and access solution, is designed to meet the growing
capacity requirements of mobile operators around the world.

The RC is a native Ethernet VectaStar hub that currently
supports doubling of sector performance to 300Mb/s, with planned upgrades
this year to deliver 600Mb/s and 1Gb/s. The small footprint RC can control up
to 8 VectaStar sectors and aggregate traffic from up to 240 Remote Terminals
in a single 1U hub. Those features exceed the requirements of network
planners designing the dense backhaul networks required to support
exponential growth in demand for mobile data services.

"According to Cisco, mobile data traffic nearly tripled in
2010 but until now operators have been stuck between a rock and a hard place
when it comes to backhauling that traffic," said Graham Peel, CEO of
Cambridge Broadband Networks. "They tell us that, for a significant
proportion of cell sites, fibre isn't practical for cost or operational
reasons and we know that traditional microwave technologies don't have the
flexibility to manage peak traffic demands efficiently.

"The VectaStar Radio Controller solves the problem with
300Mb/s sector performance immediately available, and an upgrade path to
1Gb/s before year end. Additionally our point-to-multipoint platform
architecture is inherently efficient, both in the way it manages mobile data,
and in its use of human and capital resources. Those elements combine to
create the industry's most cost effective mobile backhaul and access

The RC is based on a Gigabit Ethernet backplane supporting up
to 10Gb/s sustained operation and is a software upgradable platform to allow
for planned performance enhancements and new network standards.

John Naylon, Head of Development at Cambridge Broadband
Networks, commented: "Higher capacities and latencies well under 1ms are a
must for both HSPA and LTE backhaul. So is the ability to support IP traffic
and all-IP architectures. VectaStar Radio Controller gives network designers
all of these things in a small, efficient platform; the flexibility and
performance of the radio controller gives our existing and future customers a
backhaul platform for the future."

With the introduction of the Radio Controller, designers can
plan their high speed data networks with backhaul performance measured in
100's of Mb/s aggregated seamlessly to 1Gb/s or 10Gb/s network interface
ports, confident in the knowledge that they have a system to support their
needs into the future.

Notes to editors:

All VectaStar Radio Controller traffic interfaces are Small
Form-Factor Pluggable (SFP) based to provide maximum interface flexibility.
Eight Gigabit Ethernet (GigE) ports are used to connect VectaStar Gigabit
Access Points and two more for core network interconnections. Two SFP+ 10
Gigabit Ethernet (10GE) ports are also provided for core network
interconnection since the total aggregate rate from a full set of sectors may
exceed 1 Gb/s.

Features available at launch include a novel protected
sector capability that permits the simultaneous operation of two access
points in a sector - thereby increasing the sector capacity of a VectaStar
system to 300Mb/s. The platform is software upgradable and a roadmap of
future features is available on request.

VectaStar Radio Controller is compatible with VectaStar
Gigabit and VectaStar 2 Multipoint Radios.
