Remote via wireless bridge to apartment roof.

(1/3) > >>

VE7VR:
I live in a high rise building.

Radio is a TS-480HX

I am attempting to use remote rig to connect from my apartment on the 14th floor with the roof on the 25th floor. The connection needs to be via wireless WiFi rather than the internet since I only have power available on the roof....no internet.

I currently have both ends in the apartment and will get that working before moving them apart.

I have the radio-end router (Linksys WRT3200) in wireless bridge mode and the RC1216 (SteppIR control) and RRC1258 are plugged into LAN jacks on the router. Good news...it works. I can turn things on and change the SteppIR. I can hear audio and change frequency and transmit seems to work but with some delay. However, there is quite a delay when changing frequency. If I move the knob very slowly it is OK. When I rotate more quickly the frequency may not update for 1 or 2 seconds. While moving the frequency the audio is also interrupted.

There are also random voids in the audio on receive which are milliseconds long and occur every few seconds. Sometimes more frequent, sometimes longer intervals.

I don't think I can change any settings on the WiFi equipment or can I? Anything on the remote boxes I can try? Buffer/Jitter etc.

I tried disconnecting other WiFi equipment on the same network with minimal change.

My next option will be to change out my existing 2.4G router (Linksys WRT54GL)  and add a dual band router and move the wireless bridge (already dual band) to the 5G channel which will be exclusive of other connections.

Once this setup is solid I will need to work on external antennas for each router so they can "see" each other.

Thanks for any advice.

Hi Dave,

It is for sure a network problem. One you setup the 5 GHz dedicated network for the connection,
I am sure that it will solve your problem. You may wish to look at some other wireless bridges
designed for that sort of thing: I recommend products from Ubiquiti and something like a
Nanostation would work really great and is not expensive https://www.ubnt.com/airmax/nanostation-ac/

You can compensate for latency issues by changing those settings. I run them at 12 & 10 in
between the U.S. and Europe. However, latency is not your problem and it should not be necessary
to change these settings in your case.

Thanks very much Mitch. I see in small print on the modem setup page that 2.4ghz is not recommended for wireless bridging. I will update my primary router to dual band and post an update here once that is installed. Thanks for the tip on hardware.

VE7VR:
Update: I replaced my old Linksys primary router with the same dual band version I am using at the radio end - Linksys WRT3200AC. The wireless bridge was then set up on the 5GHZ band. All the latency issues went away and the setup works just like it did when connected via the internet. Now the challenge is to get the two routers separated by more than 6 feet. I will try just using external antennas at each end but suspect I may have to have a PoE range extender at the primary router side. We shall see. The roof-top router will require about 50 feet of coax to get an external antenna to "see" over the edge of the building. The antennas will then be about 120 feet apart.

More to come.

Glad to hear it, Dave.

Like I suggested before, take a look at the Ubiquity equipment, since they were designed for
this sort of thing. I use Bullets, but something like the Nanostation will work for you just fine.

These use PoE, so you only need to run a cheap ethernet cable to the roof edge.
