What is
VectaStar?
broadband fixed wireless
access equipment
VectaStar is a multi-service network
platform from which operators can earn
high-margin revenues by delivering a broad
mix of services, including PBX voice, E1/T1
leased lines, and high-speed Internet
connections. |
|
 |
|
Data rates of up to
60Mbps full-duplex for current and future
subscriber needs and guaranteed QoS
performance gives operators the ability to
differentiate their customer offering
through a choice of SLAs (service level
agreements) all from the same base station.
As a next-generation system, VectaStar
solves the key performance and technical
issues that constrained operators in the
past; namely limited radio coverage and
short-range links because of restrictive
line of sight operation limited data rates
and customer densities achieved within the
available spectrum high capital expenditure
owing to the large number of base stations
needed to counteract the line of sight and
capacity issues.
VectaStar uses the
inherent defractive properties of 3.5GHz
frequencies and sophisticated equalisation
techniques to achieve excellent NLOS (non
line-of-sight) coverage.
By overcoming obstacles and eliminating
multi-path signal reflections, subscriber
coverage of up to 90% can be achieved within
a base station cell. Long-range performance
of up to 30Km and beyond, together with
immunity from rain fade and adverse climate
conditions means customers can be served
with far fewer base stations than other FWA
systems.
High-capacity base stations (240Mbps
symmetrical for four sectors), the use of
dynamic modulation techniques including QPSK,
16QAM and 64QAM and a spectral and system
efficiency of 80% allows high customer
densities to be achieved within limited
spectrum allocations. |

Where does VectaStar fit within a
network?
In terms of network infrastructure, a
VectaStar system can be thought of as an
'on-air ATM switch' that provides high data
transfer rates from a relatively low cost
architecture. |
|
 |
|
All services are carried
'over ATM' and switched into the ATM network
at the base station. No processing occurs
between the CODU and the Multiplexer at the
base station allowing VectaStar to offer
full ATM quality of service and very
efficient data transfer. At the subscriber
interface, the InDoor Unit (IDU) provides
standard network interfaces and can perform
NAPT, routing, and bridging. |
