Wireless bridge to send video signal from a 2km distance

Wed Sep 20, 2017 9:12 am

Hello everybody,

I come here with a big problem I can't resolve by myself...
For a video project, I would like to do the following :

- Send a video signal from a camera (Iphone for example) to my control room situated 2km away from the camera
- The control room is doing a streaming of the video

The problems are the following :
- The camera will be in movement (in a car or on a motorbike) and will not be able to have electricity (I thought maybe about a battery for the antenna and the router...)
- The video bitrate is around 15Mbps

any idea, on how to make this ?
Thanks a lot for your answers

I didn't find the right solution from the internet.

It really sounds like you need a wireless guy to do it for you or at least a consultant.

You've got multiple shots here. You'll need wireless to hit the cars at the track, presumably, and another shot from that AP back to your office.

The biggest issue I can see with WiFi is it only works line of site. If it were me I would install an omnidirectional AP on the car (assumes a racetrack or similar) with client devices connected to it (sector aerials) and use mesh (HWMP+) to get you access to the camera stream.

There was a presentation done at the Sydney MUM 2012 from a guy in Poland that did a similar thing with an airshow. AFC 2012 by Jaromir Cihak (SysDataCom s.r.o., Czech Republic)

If the moving vehicle remains in a general location (such as on a track), then one or more sector APs facing the track should work.

If the moving vehicle is driving in a straight line, then you would need some APs along the road so that the client device can roam from AP to the next AP as you drive.

If the moving vehicle has a route that does not have AP coverage the entire route, then you can face disconnects.

We sometimes loan some video network equipment to the local school where they can have a live video channel on the Internet. The important thing is to make sure every possible location the remote is when moving has good clear strong signals to the next AP when the roaming client changes AP.

Something you should know, make all APs bridge to Ethernet. None of the APs have NAT turned on. All APs connect a wireless client to a common Ethernet natted network. This way then the client roams between APs, the client can continue using the same IP address.

Or - just use a cellular network
