Challenge: Network usage through paid public access, such as airport or hotel Wi-Fi or from telecom companies via 3G service are the largest running cost of mobility. Some of these expenses appear on monthly statements, but others are buried in expense reports. Three common areas where funds are being wasted are:

• Double paying for access by purchasing access from a hotspot or hotel when an existing subscription or free service is available. This is often paid for by credit card and is a hidden cost since it is rarely associated with the appropriate IT or telecom cost center.
• Over-plan bandwidth usage, either by going over the data plan allocation or passing the “unlimited” cap that some carriers offer. In either case, data transfer above the allocated bandwidth comes at a high premium.
• International 3G roaming: high data costs for 3G use outside the home area of coverage.

Solution: Trellia reduces the cost of mobility by allowing IT to enforce cost-based network usage policies. From automating the selection of the most cost-effective network, to disallowing WWAN roaming, Trellia's solution helps contain the scenarios that are most likely driving your access costs through the roof.

• Double-pay solution: Trellia enforces use of the most cost-effective network based on IT policies. User can be prevented from using paid access if an existing subscription service is available.
• Over-plan bandwidth usage: by constantly optimizing the cost of network usage, Trellia minimizes the use of paid services and limits the chance of end-users exceeding their 3G data allocation.
• International 3G roaming – this capability can be turned off for all or a group of mobile workers through the Trellia Policy Manager, eliminating the risk of unauthorized roaming.
