Humberside Police
The Problem
We were contacted by Humberside Police to carry out a signal site survey at Melton Police Station in North Ferriby. The station is a new construction and the modern building materials, made up of metal cladding and concrete floors, were blocking the mobile signal. The staff were experiencing extremely poor signal, zero data speeds and calls were continually dropping.
This was a large project for our team. The building is 10,000sqm, spread over 3 floors; but the main challenge for our engineers was that this facility has high security requirements. Our team needed to be escorted throughout the complex at all times. The building was extremely busy with staff carrying out confidential and sensitive work and it was paramount that our engineers remained discrete and professional.
The facility has solar power on a flat roof which meant we needed to strategically plan the position of the external antennas and carefully work around the solar panels. Following on from our site survey and signal tests, a bespoke signal solution was designed to cover all 4 networks throughout the whole of the building.
Our Solution
The Chosen Solution
Our Amplifi-Qx Digital solution was selected with the CEL-FI QUATRA 4000e. The QUATRA 4000e is a multi-carrier active DAS hybrid for 3G/4G/5G voice and data and delivers mobile signal that is up to 1000x stronger. The design was made up of 2 network units, 9 coverage units, 47 internal antennas and 8 external SISO antennas. We were able to utilise the false ceilings in the building to run our cables and we were required to fire seal throughout the installation.
Installation Challenges
Each project that we carry out has its own challenges and our engineering team are well equipped to adapt and make the necessary changes on site if needed.
Our original design for Melton Police Station included utilising a riser as a cable route. During the installation our team discovered that the riser did not lead to the area required which would increase the cable route. We always try to keep the cable used to a minimum in order to reduce the dB loss that naturally occurs when passing signal through coax cable. The engineering team redesigned this part of the signal solution on-site and the outcome was even better than our original plan.
The Results
Significant Improvement Throughout
The results following our installation were excellent. The staff at Melton Police Station are delighted with the mobile signal that the whole building now receives. They are able to make and receive clear calls and the staff have seen an instant and dramatic improvement.
Immediate Results
The customer was immediately able to see the results of our work with productivity and operational advantages. All areas of the building now receive strong and consistent 3G & 4G voice and data coverage.
