sluge Posted April 8, 2016 Share Posted April 8, 2016 Hello,I need to implement WiFi 802.11 a/b/g/n/ac protocol with SDR at 470MHz.- Is it possible to implement WiFi at this frequency?- Is any existing implementations about it? Quote Link to comment Share on other sites More sharing options...
phpsystems Posted April 8, 2016 Share Posted April 8, 2016 I'm going to assume you have a full duplex SDR, The Wifi standards you mention are at set frequencies, but I can going assume you want to want to do certain things that wifi does, Do you want to broadcast beacons and have people connect, using the methods that Wifi can employ, such as WPA, or do you just want to transfer data? If it's the later, and you want a point to point link type set up, GNU Radio is capable of transmitting / receiveing tcp/ip over radio. (See the networking tools section).

sluge Posted April 8, 2016 Author Share Posted April 8, 2016 At first I need to connect two devices. Just transfer data at first. Later I could add WEP/WPA Thanks for gnu radio. Is any issues possible with 470 MHz ? Quote Link to comment Share on other sites More sharing options...
phpsystems Posted April 8, 2016 Share Posted April 8, 2016 Range and licensing are just general issues. Make sure 470 Mhz is legal in your area. Quote Link to comment Share on other sites More sharing options...
Karit Posted April 8, 2016 Share Posted April 8, 2016 At 470MHz mightn't get through put required because frequency isn't high enough. Maybe look at the Ham data services as they have data link in the Ham bands. More likely to have worked samples/code to start from, I would guess Quote Link to comment Share on other sites More sharing options...

I found this when I was researching 802.11 modules for GNU Radio, I haven't given it a try yet but you might be able to use this and change the frequencies. https://github.com/bastibl/gr-ieee802-11 Edited June 5, 2016 by NotPike Added some usefull information Quote Link to comment Share on other sites More sharing options...
NotPike Posted June 17, 2016 Share Posted June 17, 2016 Just a thought but you might be able to use Up/Down Converters to shift over to another frequency band. Haven't seen it done before but It might be worth a try. Quote Link to comment Share on other sites More sharing options...
