Mesh Connectivity Layer (MCL)

Mesh Connectivity Layer (MCL) is a technology that allows a computer user to connect to a wireless mesh network that uses Wi-Fi or WiMax. The wireless mesh network can be connected to the Internet through a single computer using a leased T-1 line or broadband satellite connection, allowing all network users high-speed Internet access. The MCL system is being developed by Microsoft, in conjunction with several major universities, for computers that use Windows operating systems.

The MCL system consists of a loadable Windows driver that acts as a virtual network adapter. Routing is done using a protocol called Link Quality Source Routing (LQSR), which is a Microsoft adaptation of the Dynamic Source Routing (DSR) protocol. MCL holds promise for people in remote areas who have not previously had access to high-speed Internet services. A single person or a small company could lease a T-1 line or broadband satellite connection, and then sell high-speed Internet service to members of the neighborhood for a modest fee. If there were enough users in the network, this fee could be competitive with individual medium-speed satellite Internet connections.
