Air Transport Radio
Large hub airports present unique environments for radio systems. For example:
- Airports are “ports” of entry with lots of mobile roaming traffic from very high
densities of users.
- Terminals are large dispersed buildings over many floors containing underground and
subway areas surrounded by securely controlled spaces.
- Baggage and aircraft stand systems may use unlicensed frequency bands for business
critical applications alongside retail tenants with wireless point of sale equipment
sharing the same bands.
- Numerous low power radio systems need to co-exist in close proximity to high power
radar systems for detecting objects in the air and on the ground.
- High levels of security are required so that police and other security agencies need
ubiquitous and reliable access to voice and data communications.
- Thousands of staff working for operational partners including ground handlers and
caterers must be co-ordinated remotely and in real time
- Tens of thousands of airport assets from large vehicles to wheelchairs must be used
efficiently
- Airport operators need to ensure that they take responsibility for ensuring RF Health
and Safety for all staff, subcontractors and members of the public whilst on the
airport.
B Consulting are experts in design, build and operation of complex airport radio
systems. We understand how to ensure multiple radio technologies and users co-exist
and how to guarantee that relevant ICNIRP limits are not exceeded so that health
and safety responsibilities can be discharged.
A major contractor for a new airport build project needed to ensure both ground based
and ground to air radio systems would be suitable and effective, notwithstanding
significant engineering and technical constraints. Project deadlines meant that
coverage predictions were needed before terminal construction was complete. Our
previous experience of a new terminal build at a major UK airport allowed us to deliver
the required design with a high degree of confidence using a computer representation
of the as-built airport.
A large multi-operator multi-technology radio system in a large hub airport was consistently
failing to perform as required. B Consulting identified an issue with uplink noise
rise on RF over fibre components, which was marginally improved by balancing of links.
An offsite analysis of component performance (S12, S21) indicated that some remote
fibre optic repeater equipment was not correctly specified, demonstrating how correct
system design could ensure improved performance.
