In order to complete the process as a Wireless Broadband Provider, an efficient billing system must be utilized. Unisyn can recommend an off-the-shelf billing software system or provide a Billing Interface to the Providers current billing system. An effective wireless broadband billing system must be able to charge customers according to bandwidth usage at each access point delivery level. Additionally it must be able to charge customers with a "Bandwidth on Demand" basis. As the Internet matures into the next generation user, Providers must be able to provide many variations of access products, which can account for precise bandwidth usage per customer. This one issue has been the demise for many DSL and conventional ISP’s due to inefficient accountability of bandwidth usage to wholesale cost ratio.
