In case there are not enough channels available, two or more AirShares can be placed on the
same channel. This will of course have an impact on the quality of the link when several clients
are sharing simultaneously. In a worst case scenario, three base units placed on top of one
another can result in performance issues, as illustrated in Table 4 and Table 5. Table 4 shows a
scenario in which all clients are streaming video content, and Table 5 shows a standard office
situation where clients share typical office documents or presentations.
As stated above, the 5 GHz channels do not overlap with each other and are less used by non-
Wi-Fi devices than the 2.4 GHz channels. Moreover, 5 GHz signals are more rapidly damped than
2.4 GHz signals. Therefore the use of a 5 GHz channel is recommended. This will limit the impact
of an AirShare system on other installed AirShares and on other WLAN users.
