Hi friends.
can SXT5HpND communicate with another SXT5HpND on the vehicle with 80 Km/h speed ?
the SXT’s Is installed at the same height and same way.

If you have LOS.. yes
Why not

I can installing multiple SXT on the tunnel for each 200 meter. the tunnel length is 20 KM
and for this project OMNI antenna is better or sector SXT ?

I’d say this won’t work, because of roaming issues (ie. handover issues) and interference issues

You might be better using Ubiquity’s Zero-Handoff APs
or Meru’s (now Fortinet) Seamless Roaming approach.

With Microcell architecure and without extended Roaming support you’re lost here.

thanks for answer. which unifi model 5Ghz is recommended ? is unifi support mirkotik hotspot ?

12

I am not familiar with the Upiquity products. I just know that there is support for zero-handoff roaming.

Mikrotik Hotspot works as long as you establish a Layer-2 Connection between End-User and Hotspot Gateway.
This might include ordinary bridging, tunneling with EoIP/L2TP or MPLS/VPLS

Scan-list in stations, limit to APs frequency.
And use mode=station-roaming for zero handoff

thanks MR.shahbazian for reply
what about microwave radios ? for example dragonwave devices

15

nobody any idea ?

16

Use device like OmniTik for AP; because when approach the AP and when getting away AP, don’t lose connection to AP

can omnitik roaming fast wireless network from ap to ap (dynamic WDS )? for example I installing OMNITIK on train and many OMNITIK on the tunnel, is roaming fast between the two omnitik’s ? the train speed is 32 km/h up to 70 km/h

thnaks

OmniTik better than SXT for AP in this solution, because SXT cover one side but OmniTik cover two side of AP.
In configuration no deference between SXT and OmniTik.

What about train speed? Can omnitik communicating with 70 km/h speed?

In wireless interface advance tab, set distance=indoor in APs and Stations
