Re: Disadvantages of WiMAX
Like most wireless systems, available bandwidth is shared between users in a given radio sector, so performance could deteriorate in the case of many active users in a single sector. In practice, many users will have a range of 2-, 4-, 6-, 8-, 10- or 12 Mbit/s services and additional radio cards will be added to the base station to increase the capacity as required.
Because of this, various granular and distributed network architectures are being incorporated into WiMAX through independent development and within the IEEE 802.16j mobile multi-hop relay (MMR) task group. This includes wireless mesh, grids, network remote station repeaters which can extend networks and connect to backhaul.
Re: Disadvantages of WiMAX
If there are many users in one sector, they will have lower speed. If users are moving, speed can drop significantly. In the urban environment (without the optical visibility) users can have 10 Mbps at 2 kilometers.
