Range

whats range for wi-fi.???? and does it uses radio waves???

This question is perhaps best put in the Answers pages here. But, nonetheless, some comment. Range depends on quite a few things, including the emitted power of the WiFi circuits (there is a regulatory maximum in all locations -- though it's not quite the same maximum everywhere), the directionality of the antennas used, the losses imposed on the signal by obstructions in direct line of sight and indirectly in the Fresnel zone, air temperature, humidity, etc. The maximum possible under the least interference with the strongest signal output is several miles. In practice, with the common omnidirectional antennas (e.g., the rubber ducky ones), the maximum distance is a couple of hundred feet. Note that, as signal strength is reduced, WiFi units back off on the modulations used and so reduce the data rate. In general, the data rate at max range (and minimum signal strength) will be low.

WiFi does use radio signals. 802.11a in the 5GHz range and 802.11 b/g/n in the 2.4GHz range. The latter are close in frequency to that used by microwave ovens. Note that the modulations used are far more complex than AM radio, FM radio, or shortwave radio. WiFi signals can't be meaningfully decoded by ordinary radios, including scanners and such. ww 04:47, 8 September 2006 (UTC)[reply]

Fidelity

if HI-FI = High Fidelity, does Wi-Fi = Wireless fidelity? or is the name just a crappy acronym with no real meaning?

It is a trademark, so just needs to sound good, not stand for anything particular. General name for the technology. W Nowicki (talk) 18:28, 7 November 2013 (UTC)[reply]

Original name

Before hiring Interbrand in 1999 to come up with the term Wi-Fi what name did this organization go by? 64.228.88.84 (talk) 17:05, 19 April 2015 (UTC)[reply]

Serial comma question mark

The group of companies included 3Com, Aironet (acquired by Cisco), Harris Semiconductor (now Intersil), Lucent (now Alcatel-Lucent), Nokia[serial comma needed?] and Symbol Technologies (now Motorola).

The mergers are so complex and variegated it would take ten minutes of intense study to determine whether adding the serial comma is a correct edit. [Edit: For clarity, the issue here is the scope of the modifier "(now Motorola)".] — MaxEnt 23:25, 5 July 2015 (UTC)[reply]

Source for Old Logo?

The thumnail logo says it is the old logo. However, I can't find a "new" version of the logo. What makes this the old one?
