Few more ideas for the audience to consider. Newer iterations of wifi are no better than the older versions is very misleading.
What the idea says,
a. The big corporations who dominate the 802.11 working group have created the 802.11n/ac/ax supplements with characteristics that have appealing maximum information rates, which are realizable only in a green-field environment and certain favorable use cases, have two to three orders of magnitude higher (100 to 1000 times) higher information rates than those of 802.11a/g under similar conditions;
b. However, the big corporations undoubtedly do know and likely have always known that the 802.11n/ac/ax suppliments’ appealing characteristics are largely ineffective in general environments and demanding use cases and so have information rates approximately equal to those of 802.11a/g under similar conditions.
"I have no idea what the definition of general use cases is."
The above phrase "general use cases" is inaccurate. The phrase should be general environments and demanding use cases.
a. The environment must have all wireless LANS (WLANs) with channels adjacent to the primary channel of the WLAN under test either the 2.4 GHz or 5 GHz band loaded to represent adjacent channel interference (ACI);
b. The number of clients in the basic service area (BSA) of the WLAN under test must be large enough to represents a general use case and their service request rate and aggregate demand must be a representative proportion of the WLAN’s channel capacity;
c. The AP STA and the service set (SS, “client”) STAs of the WLAN under test must be distributed throughout the BSA in a way that is representative of a general environment (e.g., the average distance between the AP and the SSs should be about 30 to 50 feet);
d. The BSA environment should include reflective surfaces and walls to cause signals transmitted and receive between the AP STA antenna(s) and the SS STAs antenna(s) to echo and be delayed to cause a representative amount of multi-path fading;
e. The average MSDU (MAC Service Data Unit) size should be typical for the number of SSs associated with the WLAN under test and for a for typical use cases.
These conditions will test practically all of the 802.11n/ac/ax supplements’ appealing characteristics and can demonstrate that they ineffective in general environments and demanding use cases so their performance will be similar to that of the 802.11a/g supplements.
The test would be similar to the tests used by certain of YFI’s potential customers (e.g., cablecos through CableLabs and enterprises like Kroger) for competitive head-to-head testing of a single radio in YFI’s multi-radio 802.11a/g AP STA unit solution vs. competing single-radio 802.11ac AP STA units, when using 802.11a/g/n/ac SS (“client”) devices in order to verify their relative performance and validate their ability to fulfill their purpose.
However, the simple test run at home almost certianly will not provide the conditions above and so the results will inadequate.
"Anyway if you buy into the conspiracy theory [that] the wifi companies are basically lying about the performance abilities of their units take a bow."
The statement said is that, [n]aturally, the big corporations’ marketing departments have used and continue to use the maximum information rates to promote their 802.11n/ac/ax supplement-compliant product and apparently have kept and continue to keep the fact that in real-world general environments and reasonably demanding use cases their performance is little or no better than those of 802.11a/g amendment unit products. So, technically the big corporations cannot be accused of lying.
An analogy would be a car company (e.g., Farrari) selling alluring models with a very high maximum speed performance numbers when knowing that those models can only achieve those maximum speeds in a in special racing (greenfield) environments when driven (used) in racing condition cases. Whereas, when the aluring model cars are driven in general enviroments (city center, suburbs, freeway) during weekday daytime traffic its speed won't be much better than that of regular performance cars.
