70% of all mobile calls are made from inside a building where mobile signals are often diminished because of building materials or other hidden barriers which stand in the way of a strong signal. This is why we have partnered with Nextivity to install their industry leading CEL-FI cellular coverage solutions. CEL-FI systems help organisations achieve strong carrier signals, keeping businesses, employees and visitors connected.
PHTA is designed to accommodate researchers at the proof-of-concept stage through to spin-out companies and beyond – providing small health innovation businesses with much-needed grow-on space. Excellent connectivity, including multi-operator mobile coverage, is therefore essential and expected by our clients. Following the success of Simpli-Fi's proof-of-concept Mobile Signal Boosting Solution for the campus hotel, we approached the Simpli-Fi team to consult, design and deliver a system to ensure we had excellent, future-proof connectivity throughout the PHTA facility.

What is an in-building mobile network signal booster?

- No dropped calls.
- Faster data downloads.
- Improved voice clarity and streaming.
- Better battery life.
