which otherwise had large coverage black spots, especially in E&A. We surveyed, designed, supplied, installed, commissioned and maintain a 3-Sector Zinwave Active DAS on a 4hour Call to Fix SLA (Service Level Agreement). A recent national BBC News clip showed a highly dedicated Critical Care Nurse working with Covid-19 patients at the height of the pandemic using mobile phones to FaceTime two elderly patients, married for 60 years, she was caring for, both ill with Corona Virus but isolated in separate wards to provide reassurance.

in the hospitals newest (PFI) wing and the executives’ corridor. We obtained the first Zinwave DAS UK Mobile Network Operator’s JOTS (Joint Operators Technical Specification) technical approval for this from O2, Vodafone & EE and their sign-off of the installation. The system has been fault-free since Go-Live (+5years) and EE, O2 & Vodafone all upgraded the 4G services during the height of the Covid-19 pandemic in April 2020 to provide higher data capacity and reliable VoLTE voice calls for senior management & clinicians; we didn’t need to enter the lockdown hospital and upgrade the DAS, it was future proof from day 1.

desk phones and use mobile phones! This Mobile 1st policy proved doubly wise when the Covid-19 pandemic hit and staff were asked to work from home. In an almost seamless “business as usual” transition their existing corporate providers of mobile SIMs (EE) and devices (Computacenter) deployed many thousands of additional units to enable virtually all of their office and branch-based staff to work remotely. It’s anticipated that 20-25% of staff will return to their offices which benefit from previously installed & maintained multi-operator (EE, Vodafone & O2) mobile phone signal boosting systems, several of which Herbert In-building Wireless Ltd maintain, including their Head Offices in Gogarburn, Edinburgh.

Addenbrooke’s hospital next door, but added Crash Team Paging over the DAS. Royal Papworth hospital headed up the Regional Covid-19 response with Dr Roger Hall, Medical Director, leading this Clinical Decision Cell.

A Covid-19 patient said on BBC News “it was a godsend to be able to FaceTime each other when survival was so uncertain”. O2 upgraded their 4G Base Stations at the height of the pandemic to provide higher data capacity without us having to upgrade the DAS.
