in the old days of 802.11b the rule of thumb was 10 lamdas I don't think that DSSS versus OFDM would change anything. It should be pure physics (anyone can help on this one?)
f=c/lamda where c is 3 * 10 E8 m/s (speed of light) and f = 2.4 10 E-9 Hz ( 1 Hz = 1 cycle/s) that's about 10 * 0.1 m ... final approximate answer: ~1 meter or ~3 feet Philippe Hanset Univ. of TN On Thu, 15 Jan 2004, James Savage wrote: > Hi, > I recall someone mentioning an issue when co-locating APs/antennas too close > together (within a few feet) even when they're broadcasting on difference > channels (1,6 or 11).
