National distribution centre creates blanket mobile phone reception with PMT’s In-Building Coverage solution

“Our autonomous machinery, duress systems, staff, contractors and visitors have full mobile signal from the time they arrive on site”.

A chain of national Distribution Centres (DC) identified possible mobile phone signal issues at the time of facility design, due to construction materials and warehouse racking. To ensure a smooth transition to the new facilities, the operations team included a solution in the build. 

Looking at the available resources, IoT-connected devices and other operational equipment inside each facility it was decided that mobile coverage would need to be improved in order to maintain efficiency and – above all – employee safety.

The installation of PMT’s In-Building Coverage (IBC) solution economically solved the issue by improving mobile phone reception for Telstra, Optus and Vodafone/TPG across the entire site. This improvement in coverage included all warehousing (dry and cold), corporate offices, staff amenities, machinery & utility buildings as well as receiving and dispatch docks.

  • With 95% coverage in the target areas of the DC, equipment, team members, visitors and contractors can now use their mobile phone and tablets throughout the entire location.
  • Improved coverage ensures the ability to make and receive phone calls, access the internet and custom site-specific apps. Realtime machinery tracking, information and statistics processes are also now fully functional.
  • Safety, security and functionality were a major factor in sourcing the solution.

Operating 24/7, the distribution centres are essential to the success of the business, keeping retail outlet shelves stocked across each state daily. With a heavy reliance on mobility, any issues with signal quality have a significant impact on productivity – not only for staff, contractors and visitors, but equipment as well.

“Our business in supply chain relies heavily on mobility. As such, a poor signal anywhere on site effects our day to day operations and our bottom line.”
