Did you know?
The most popular ISM band for WMN seems to be the 2.4 GHz ISM band. Its worldwide availability is attractive and promises a lot of benefits. Achievability of relatively high transmitting power seems to be advantageous, and it is a nice tool for engineers looking for simple solutions. However, there are some interrelations and limitations, e.g. between wavelength and the ability of radio wave to penetrate walls. Our world is full of walls, which is why 2.4 GHz (marketing driven) enthusiasm has slightly decreased and new ISM subGHz bands were re-discovered shortly after the first low power WMNs (wireless MESH networks) had been practically tested.

IQMESH – wireless network with MESH topology

In wireless networks type MESH, data packets are delivered by routing mechanism (via nodes in the network). This approach increases the range, robustness and reliability and fixes potential problems of Star topology.
