CAMBRIDGE, England, February 7 /PRNewswire/ --

- Cambridge Broadband Network's VectaStar has the Best Frequency Coverage
of any Point-to-Multipoint Backhaul Solution

Cambridge Broadband Networks today announced the commercial availability
of its VectaStar intelligent point-to-multipoint (PMP) microwave backhaul
platform in the licensed 28GHz frequency band. The VectaStar portfolio now
provides mobile network operators with complete flexibility in the design of
backhaul solutions to meet the dramatically increasing demand for mobile data
services. The portfolio now covers all major backhaul frequency bands
(3.5GHz, 10.5GHz, 26GHz, and now 28GHz) to deliver future proof and highly
efficient solutions that can be implemented in established and developing
markets around the world.

VectaStar uses point-to-multipoint microwave architecture to meet
operator's core backhaul requirements using popular interface protocols and
it enables migration to an all-IP Ethernet network.

Deyan Boyich, VP Product Marketing, Cambridge Broadband Networks,
explains: "VectaStar uses a highly efficient and flexible architecture
designed to meet the needs of mobile operators today and it is scalable to
meet the explosion in demand for high capacity data services. With the launch
of the 28GHz product we can now deliver solutions across all frequency bands
in all markets. The 28GHz band is already in use for backhaul in a number of
countries including Italy, Portugal, Norway and Belgium. In the UK, industry
regulator Ofcom recently called for operators to register their interest in
securing access to the 28GHz band.

"The significance of the 28GHz band is that it makes it possible to
deliver tremendous incremental backhaul capacity using the right technology.
Operators planning for high capacity HSPA, WiMAX, EV-DO and LTE deployments
can use VectaStar in this band to provide more than enough backhaul capacity
to support the needs of consumers for capacity hungry data services."

VectaStar's efficient use of spectrum is complemented by a unique
integrated multi-protocol QoS management layer and optimisation capability.
Its advanced transmission features and tightly-coupled data optimisation and
aggregation enable data optimisation at the edge of the network. In support
of this, and to ensure maximum data throughput in a sector, all service types
are simultaneously statistically multiplexed, which means VectaStar can
effectively carry at least four times the data of any competing system in the
same over-the-air bandwidth.

VectaStar's combination of PMP architecture, advanced multi-frequency
transmission capability, and intelligent data optimisation and aggregation
make it highly cost-effective for today's backhaul. The consequent reduction
in OPEX helps network operators to cope with the downward pressure on
operating margins while VectaStar's scaling and future-proofing enables their
backhaul systems to match the explosive and uncertain future growth in data
traffic."

About VectaStar

VectaStar is a highly flexible, scalable point-to-multipoint radio
transmission system that can be used for 2G and 3G cellular backhaul,
WiMAX/WiFi/DSLAM backhaul and Enterprise access. VectaStar is the only
transmission solution with integrated Abis and Iub optimisation and dynamic
statistical multiplexing to maximise the traffic that can be carried in any
given bandwidth. This provides operators with the most efficient use of their
radio spectrum and gives substantial operational and capital expenditure
savings compared to leased line solutions. VectaStar's additional advantages
include its superior capacity, range, service mix, spectral efficiency and
built-in support for full redundancy. VectaStar seamlessly supports E1/T1, IP
and ATM transmission protocols, providing operators with a comprehensive
range of service offerings within a future proof platform. A single VectaStar
base station supports simultaneous operation in the licensed 3.5GHz, 10.5GHz,
26GHz and 28GHz spectrum bands.
