Tesco Cuts the Cord

UK supermarket chain Tesco is building its own GSM network, an unusual step for any enteprise to take. The retailer will construct a private GSM network to replace its existing fixed-line phones at about 1,500 locations, CommsDay reports. Cable & Wireless will provide the backhaul and Ericsson will design, build and manage the network for five years.

Inside buildings and on Tesco campuses, mobile handsets will act essentially as cordless phones. But those handsets also will roam to the public GSM network off campus or outside buildings.

In many ways, the Tesco network is one of the more significant enterprise fixed-mobile converged networks so far. Tesco will use its existing IP network for voice trunking, while replacing tethered phones with mobile handsets that double as traditional mobile phones when outside the office.

By doing so, Tesco eliminates desk phones and all the maintenance,moves, adds and changes associated with use of those phones. To the extent that unified communications and FMC are at least in part about reducing the number of devices or phone numbers or mail boxes any single user must interact with, Tesco's network eliminates all support requirements for one of the two voice services it used to support.
