WiFi Distance Test two - 3.22 miles on semi portable WiFi system

[kc8ntp]

Just shy of 2Mbps, not too shabby. I am setting up a similar setup for a 5-mile link that is pure LOS. I have modeled it with some software that I have and it should be more than possible. Also, your setup should have been around -70dBm at this distance, which is just about perfect! I am a HAM, too, BTW. 73, de NV6R

@kc8ntp

Thank you for your comment.

I am more than confident that the link you are setting up will be quite stable, with good signals. I was very surprised that my link worked, as there were many variables, being so close to ground level, and the amount of high sides Lorries! The link does stall at one point but gets going again on the download of an image you saw. Considering that the AP antenna was an 8dBi Omni its even more impressive!

Good luck and let me know how you get on

7 3!

Where can i buy one of these long range antennas? I live in aparments where the wifi is free but its at the office and its about 100yards from my place.

[cyberjackcyberjack]

what the antenna ? yagi ??

[fezuk2006]

Nice video but.

Surely a ham license only permits use of your licensed power on specific ham bands?

Please feel free to correct me.

[HubSwitch]

You are absolutely correct!

The ham band for 2.4Ghz falls in the wi-fi channel range.. How nice :o)

Band plan snippet 2,400.000 - 2,450.000

Google "RSGB Band plans" to see what we can use here in the UK.

Thanks for your comment

[fezuk2006]

How very nice.

Thanks for the swift reply, I think I need to buy some amps.

[pitbike2006]

can i use a sky tv mini dich and use the LNB on it becouse it looks like a colose to the same connection cable but what would it do and i have a UK VHF licence can u go any higher watt's hope u can help me

[HubSwitch]

yep you can use a sky dish, nope you cant use the LNB, you need a intermediate or full amateur ticket for transmitting on 2.4Ghz spectrum.

As for power.. you can buy power boosters, though I belive that these are not legal - they break the FCC rule: 100Mw Max ERP.

Cables, you need P-R-O-P-E-R Cable:

A few to point you in the right direction

LDF450-ecoflex15-HD200-LMR400

And what the heck is a UK VHF Licence? never heard of it!

[HubSwitch]

Nope, its a yagi.

[technoboi0]

I was confused by the comment that the maximum ERP allowed is 100mW but that you can use a higher power as a Radio Amateur. I don't have my licence in force currently so I am not familiar with any changes that have taken place over the last few years. What does the licence say now about power allowed for WiFi frequencies? All I am aware of is use of specific amateur radio frequencies. What frequency did you use for this communication?

[HubSwitch]

as an intermediate licence holder I am allowed upto 50W output.

I used channel 1 (2.412Ghz) as far as I can remember for this test.

the erp was around 1.5W for the (14dbi) beam, and 800mW for the (8dbi) Omin

[cyberjackcyberjack]

3.22 miles for wifi ? that,s not possable ?! as yes you prob be able to receve the signal on a good antenna BUT the AP would'nt be able to transmit back, it would be out of range as even the most fast AP will only do about 400 - 460 meaters !!!

[HubSwitch]

LOL...

You've not read the video details?

BOTH AP and Client are running 200mW

Client has a 14dbi yagi and the AP has a 8dbi omni.

Both systems only have about 50cms of coax, and as so, stops major losses of signals like you get in conventional coax based systems, plus costs are further reduced as you dont need to buy expensive coax runs!

Thanks for your comment

Is this a Power Over Ethernet appliance?

And do you happen to know what 12 is in -db?

[HubSwitch]

Hi, this is a PoE, because I have used adapters to make it that way, otherwise its just a standard 12V system.

The "12" is what the "site survey" sudjested what the signal was, there are no charts describing the db value, pitty, though the highest value I have seen on the unit is 100

thank you for your comment

[isaacu]

Thanks much.... Also, are you shooting through much foliage??? I have found this to be the downfall of 2.4.... I have tried up Vertical and Horizontal Polarity with mixed results. I am using pacific wireless antennas usually 9-15db.. I'm amazed to see you getting 3 miles without a visual of the other end...

[HubSwitch]

Not much foliage mostly feilds, not tried horizontal with this setup, this yagi is fixed for vertical, I could drill holes and go for horizontal..

Cough... your amazed that it worked without a visual!?? how do you think I felt when I saw it connected! :oD

I have tried horizontal with a different yagi, and have been seen using "netstumbler" at about 20 Miles, I was running 500mW into

12M of LDF550 + 4M Ecoflex10 the other person didnt try to connect, not enough power, we are both LOS.

[sunfire73]

hello where you get yagi antenna I want one can i buy from you ??
