Looking for examples covering small, medium and large customer infrastructure installations; (1) What are the typical distances between access points? - are there any "rules of thumb" when setting-up a WLAN infrastructure installation?  (2) How does this change with 802.11 b/g, a and n installations? (3) Has any data been collected on how Symbol/Motorola products perform in relation to select Competitor's products in these deployed senarios?... (4) Any other related insights to share?  Many thanks in advance.
