Is Mesh-type networks each of the users can be directly connected to each another one user - Point-to-point connectivity.

According to the channel type the corporate networks can be organized as SCPC networks or TDMA networks. In SCPC (Single Channel Per Carrier) networks one user is using only one channel. In TDMA (Time Division Multiple Access) networks several users are sharing the same data channel at different time slots. SCPC is more suitable for broadband solutions and continuos network load.
