Channel Comparison - SRR and 802.11 b,g Channels
865351 Channel Selection
For 2.4 GHz Smart-hopping networks, both the Smart-hopping radio and the short-
range radio operate in the 2.4 GHz band, and therefore are subject to interference
from other devices that operate in this band like 802.11 b/g wireless LANs,
microwave ovens, Bluetooth radios, etc. The most likely interference will come
from 802.11 b/g wireless LANs.
In order to reduce the chances of interference, the Smart-hopping and short-range
radio channels should be chosen to operate at frequencies that avoid any 802.11 b/g
channels that are in use in the hospital.
In addition, if the short-range radio will be used, interference between the Smart-
hopping radio and short-range radio must be avoided by separating these channels
by a minimum of 5 MHz.
