According to Chau, operators take various measures for the new policy. "CSL has already upgraded its infrastructure, now having a fiber-connected network, while PCCW Mobile--having dropped its unlimited data plans-- has deployed more than 9,500 hotspots for Wi-Fi offload," he said. "Their customers hopefully will see the least impact on their data access."

For CLP the drive to be mobile has been happening for some time with use of mobile devices for field engineers for at least ten years. But as the use of smartphones, iPads and other devices grown, the ability to standardize has been made much more difficult for the IT organization at CLP.

This trend has challenged IT to find ways to support more than just one device or platform. "We have had to become more flexible to support different devices and our security and management platforms now need to be much more device agnostic and support different platforms today," said Andre Blumberg, head of group applications development and support at CLP Group.
