antennas and feeders
Compliant. Ultra High Perfomance (UHP) antennas offered with dual pola
(vertical and Horizontal) operation on a single frequency: 56MH)
Compliant. Space Diversity operation offered. Two antennas per site
each with vertical and horizontal operation on a common frequancy.
Compliant. 522 Mbit/s offered.
Compliant: The Radio Link must Secure Protection for all HW including:
Antennas, Radios, Feeders/Cables and the baseband cards, if a failure
loccus in any part of these HW components then the whole traffic to be
shifted to the second les
Compliant. The radio, antennas, feeder, power supplies etc are all

Compliant. 522 Mbit/s 56 MHz operation offered.
Compliant, Full redundancy offered.
Long range directional antennas offered for point to point long range (30
Km) operation. Point to multipoint operation would necessitate the use
of omni-directional or semi omnidirectional antennas. The radio
equipment can be used for point to multipoint operation if appropriate
antennas are used.
Compliant - A compromise needs to be made between antenna size, data
rate and availability. End user has specified minimum 500 Mbit/s and
Imaximum 2.4 metre antennas and therefore estimated availability will be
99.39%. 99.99% can be achieved with 350 Mbit/s data rate or 98.42%
with 1.8 metre antenna options and these calculations have been
provided as attachments.
Compliant and as per calculations provided. Humidity and rainfal have
been factored into the calculations provided.
Compliant. Comprehensive Control and monitoring offered including
ethernet based switching
