"Further to proposing the best technical solution with highest transmit power hence the smallest antenna size to meet our unique weather and
tower loading conditions, we valued NEC's high level of competence in providing network design and training for our engineers that will ensure we have the skills to maintain the network in future," Mr Preedy added.
The prime challenges when providing 'fibre to the antenna' include saving on installation costs and keeping down power consumption of RRUs (radio remote units) and '
tower loading'.
The WTM 6000 is also the first trunking radio in its class to support 256QAM Adaptive Coding and Modulation (ACM) to enable operators to achieve higher link capacities with smaller antennas, which in turn reduces
tower loading and infrastructure costs.
Building a completely independent GSM/GPRS system at existing sites is also expensive, while adding new antennas is often impossible because of
tower loading and other restrictions.
To propose the best technical solution with the highest power is the smallest antenna size to meet the weather and
tower loading conditions.
This innovative structural design minimizes materials without sacrificing mechanical stability, which makes the antennas ideal for deployments where zoning restrictions and
tower loading are key considerations.
This will include securing a consultant to plan the back-up radio system to include: system planning and engineering, propagation and
tower loading studies, coordination/licensing of UHF frequencies, developing bid specifications for required radio infrastructure and installation/integration services, and to guide installation of the system.
