With the draft of 802.11n fresh off the presses, questions are already popping up about the usefulness of the technology, particularly in large, multi-AP environments like University campuses. There also seem to be some questions about the effects of 802.11n networks on existing b/g/a networks as wider 40Mhz channels might interfere with existing systems. Despite it being a draft and despite questions being raised, manufacturers are rushing to release 'pre-n' products now rather than later.
