Actually, there are laws; laws against false advertising. According
to our in-house WiFi guru George Ou, most of the WiFi vendors are getting away with murder and no one is holding them accountable for it.
Whether those vendors are making claims about their proprietary "turbo" modes or their pre-802.11n gear (the standard isn't yet ratified), the vendors' peformance claims for the supposedly faster WLAN equipment clearly outstrip what can practically be attained in real world situations. Ou points to benchmark tests on TomsNetworking
as evidence of the delta between what buyer's can realistically expect and what vendors are claiming for their gear. Say Ou, if Apple was held accountable for misleading iPod buyers about battery life, then so should WLAN vendors who are misleading the public about throughput expectations.
I agree. It's not about what vendors' tests turned up in some sanitized lab environment. It's about what happens when we open up the box and plug it in.
