One proposal of McConnell's Cyber-Security Policy, which is still in the draft stage, is to reduce the access points between government computers and the Internet from two thousand to fifty.
A video agent, which is embedded in the access points between the mesh network and the Internet, receives video frame requests from all mesh nodes and chooses a proper path with minimum path contention to send the video flow to them.
Wi-Fi signals can be hampered by walls, doors or large furniture between access point and computer.
Rapiński et al. [14] investigated the influence of the obstruction of line-of-sight between access point and transceiver by a human body in indoor positioning systems.
Even if the access point could adequately manage between the two bands, it is still unaware of the other access points in the house, unable to hand off as devices move.
Characteristics of protocols at higher layers, the influence of the number of devices connecting to an access point, and the interference between devices can be characterized and taken into account in the algorithms, in order to further improve coverage estimations.
where PL [dB] is the total path loss along the path, PL0 [dB] is the path loss at a distance of d0 according to the distance loss model, d [m] is the distance along the path between access point and receiver, d0 [m] is a reference distance, and n is the path-loss exponent.
