The sports retailer has signed a 5m, three-year deal with communications integrator Affiniti to upgrade systems at its head office and 250 stores nationwide.
The project will provide a converged IP voice and data network. It is expected to improve access to management information and allow central systems to be updated in real time.
SportsWorld IT director, John Ashley, said, "We needed to improve the customer experience and align back-office processes to ensure savings on all fronts, not just on the shop floor."
PDAs will enable shop staff to check stock availability without leaving the floor, and warehouse staff to maintain records.
Affiniti will manage the infrastructure remotely from its network operations centre in Hemel Hempstead.
