Abstract :
A hybrid LAN topology including wired end systems and movable or moving end systems in an industrial environment is presented. The hybrid topology is built with a MAP backbone and infrared star subnets. LLC type 1 and LLC type 3 primitives are combined to allow the different kinds of stations to communicate according to an LLC type 3 service. The use of the connectionless mode with acknowledgment greatly improves the security of communications. Data exchange between two mobile devices is described in more detail, and an implementation approach is provided
