Talk:Long-range Wi-Fi

Interference
Regarding the subject of jammers and the video sender jammer product I have found and mentioned, I think that it is worthy of inclusion.

I'm not advertising the product, hence why I did not originally put a link to the website.

However, jim.henderson undid the revision for the reason:

Unlikely (wrong freqs), irrelevant and uncited

I therefore replaced it, with a citation, which explains the frequencies which it works on are the same, how it works and suchlike, which I think makes it worthy of inclusion.

However, it has again been removed, this time without reason.

Which is why I have put it on this talk page to be discussed.

"As Far As We Know"
Aside from this entire article being completely under-cited, "As far as we know" should not appear in an encyclopedia article. Who is 'we?' Is it Wikipedia, the editors, this specific editor? This line just doesn't belong here. If you can not find a decent source that provides grounds for the claim, then the section should be called 'an example of a long range wi-fi system,' or something along those lines.

Again, this entire article is poorly cited. The three references given are minimally related to the main topic. On top of that, two of them are claims made by a website that sells the items in discussion. How was this considered a reliable source? Aside from the problems with wording and citation validity, this article is written like a "hodgepodge" essay.

On a personal opinion note: It is incredible to me that someone would delete one thing from this entry while leaving another; as though "Unlikely" constitutes a drastic infringement, while failure to provide any relevant references is acceptable. —Preceding unsigned comment added by PromisedProgress (talk • contribs) 02:49, 26 December 2008 (UTC)

references?
- the use of the term "long range wifi" as depicted on this page for extreme ranges is not in any way endorsed, tested or certified by the Wi-Fi Alliance for interoperability or performance. -has also been used in experimental trials in the developing world to link communities separated by difficult geography with little or no connectivity options.

I've only got this far in the article. Seems to be almost completely just points of view and no references. —Preceding unsigned comment added by 86.42.200.29 (talk) 18:35, 15 January 2010 (UTC)

World record
The statement "The longest unamplified Wi-Fi link is a 304 km link" seems to be incorrect; the forum thread which is the only reference in the article for this claim itself acknowledges the 382km 2.4GHz link in Venezuela:

http://ci-journal.net/index.php/ciej/article/view/487/402

I think the "longest..." claim should probably be removed (or clarified to be the longest 5.8GHz link); additionally a new description of the 382km link should probably be put in the Venezuela section. Full Disclosure: I am a member of the TIER research group, which did work with Ermanno Pietrosemoli and his team to create the link (though I did not directly participate in that link). — Preceding unsigned comment added by Podolsky (talk • contribs) 23:36, 8 July 2011 (UTC)

Type of antenna
Readers' usage of this topic usually bifurcates between transmission and reception -- not always together. The topic generally needs to be subdivided along those two categories after describing general principles like directional vs omnidirectional.Thisibeheld (talk) 15:40, 21 May 2015 (UTC)

"Unlicensed Spectrum"
Obviously, this may vary between jursidictions, but in most countries I'm aware of, the claim that you can legally do long-range wifi unlicensed is a misconception. The license waiver for wifi frequency bands is usually limited to tranceivers below a certain level of power, and that power is generally specified in terms of Effective Isotropic Radiated Power (EIRP). This means that the combination of radio, antenna and cabling must not radiate in any direction with greater power that an isotropic radiator (a point source that radiates equally in all directions) with the given power level would. As wifi transceivers are invariably designed to meet this maximum power when used with an omnidirectional antenna, the use of any sort of directional antenna immediately smashes this limit.

This doesn't mean you can't legally do long-range wifi, but it does mean that to stay within the law, you will need to go through whatever process your jurisdiction has to apply for a license for the greater EIRP.
