I'm planning a wireless deployment for our small two-level nursing home. I need to support our own laptops which all have 802.11n WLAN cards as well as visitor's laptops which will certainly include folks with 802.11b/g cards.
I'm presently considering deploying the HP MSM410 access point, which supports 802.11a/b/g/n. It has a single radio.
Will the presence of 802.11g devices decrease the effective range of my access points for N clients? For example, suppose I assume I will only have Wireless-N clients and space my access points further apart to take advantage of 802.11n's increased range. Then, someone with a 802.11g device connects to one of my APs. Will that AP's range be decreased for all clients, including N? Or will N clients experience the same coverage, and G devices experience coverage gaps between the APs (because they were spaced for N, not G)?
Or...does the increased range of 802.11n benefit 802.11b/g clients as well?
