Nobody is 'right'. We're all wrong to some degree. I based my assertion that there is no such thing as a "WiFi Switch" on the fact that the term/phrase has been co-opted by lay and marketing people to describe all manner of things related to Wifi--not a singular thing--including, but not limited to:
WiFi controlled light switch WiFi remotely switched AC power outlet Wireless Router with wired Ethernet switch Laptop WiFi antenna [en|dis]able via physical or software "switch" As it turns out, there is an actual device whose official name is "WiFi Switch". It's a solid state integrated circuit switch, actually a family of IC switches, present in every wireless device, whose functions are one or more of the following, depending on IC model, in order of functional capability importance: 1. Switch at high frequency between transmit and receive ports on the network interface IC because radio is not a full duplex technology 2. Switch amongst multiple antennae on devices such as routers and APs possessing 2 or more antennae, simultaneously with #1 in some designs 3. Switch between different network device IC ports, such as a cell network IC and 802.11 IC, or simply different ports on once IC if it integrates both physical protocols--used in smart phones, etc Some, but not all, of these IC also have a no-connect switch position, which provides the facility for disabling the antenna(e). This one function of many, not included on all switch ICs, and the least important of the bunch, is apparently what most lay people consider to be the sole function of a "WiFi Switch". I always take exception to lay person use of terminology, with good reason, because the meaning can be different in the minds of different people. That's the purpose of standards. In this thread, everyone but me has been using one of many layperson definitions of "WiFi Switch", not the technically correct definition presented above. The following document from a leading manufacturer of WiFi Switch ICs provides the technical data proving my points above: http://www.rfmd.com/CS/Documents/BR_Switch_LNA_FE_Solutions.pdf Maybe this can finally put this time wasting sub thread to rest.
