i. Static Channel Allocation in LANs and MANs.

since each user has a private frequency band, there is no interface between users. In most cases, the size of the channels is equal. If there are N users, the bandwidth is divided into N equal-sized portions each user being assigned one portion. Each of these channels is assigned to one user.
Here, the total bandwidth is divided into N discrete channels using frequency division multiplexing (FDM). if there are N users, the bandwidth is divided into N equal sized portions each user being assigned one portion. Static Channel Allocation in LANs and MANs: It is the classical or traditional approach of allocating a single channel among multiple competing users Frequency Division Multiplexing (FDM) . The traditional way of allocating a single channel, such as a telephone trunk, among multiple competing users is Frequency Division Multiplexing (FDM). Suppose that there are N competing users.
