Hello
Is it possible to connect SXTsq 5 ac with OmniTIK 5 ac?
Which is the max distance for this link?
How much is the max capacity?
How many SXTsq 5 ac can I connecto to OmniTIK 5 ac?
- Obviously.
- At sight. The further you go, the less is the capacity…
- The question assumes that is already know the distance, number of clients, interference, government regulation, etc.
- The same reply for point 3)
Distance about 500m
Clear. No trees no buildings.
I guess it’ll work 700-800 mbps? What do you think?
It’s unrealistic speed (without knowing “number of clients, interference, government regulation, etc.”)
You have an omnidirectional antenna that senses disturbances coming from any direction…
It’s not like a point-to-point link made with two SXTs…
Max speed, ignoring “number of clients, interference, government regulation, etc.” is like to be ~400Mbps
Indeed unrealistic speed.
SXTsq ac and Omnitik 5 ac are normally used with the classic WLAN driver (not wifiwave2)
In that case an optimal interface rate of 866Mbps will deliver some 360Mbps as theoretical maximum, in one direction. (Wifi is half duplex!)
With 40 MHz channel width I get 260Mbps data rate in one direction when at 433Mbps interface rate, distance 70m., or 120/128Mbps bidirectional.
The higher the interface rate, the more % time is spend in channel access check and overhead, as the transmission of data itself gets shorter in time.
Cube60 over 70m (2400Mbps interface rate) gets 540Mbps data rate in one direction, or 160/420Mbps if bidirectional.
1Gb Ethernet cable does 960/960Mbps
on 40mhz channel which is realistic for such a deployment, i have never seen more than 170mbit tcp betwen an omnitik ac and any client device we had (be it sxtsq or lhg5ac), regardless if on the omnitik were 3 or 13 clients. urban 500m is probably too much for sxt as client device, we used lhg for urban deployments, later we pulled down all omnitiks and went with sectors, omni is a disaster in urban areas.
rural we’d put even 15 clients on an omnitik, complete radio silence in those places. sxt for even 1.5km from omni, and lhg for 1.5-5km. again, rural, with no other wifi in air. worked great. but still, never saw more than 170mbit tcp. on such locations, even with -70dB we’d get max speed. in the city we tried to be at about -50dB and still had problems.
Interesting data.
My 260Mbps is not with Omnitik but with SXT SA5 (indeed omnidirectional is a challenge here) and with 5 SXTsq 5ac clients.
SXT SA5 and SXtsq 5ac have similar antenna gain, are are a good match. (Omnitik is weaker antenna gain)
Best performance is with nv2 protocol. Test was with 1 SXTsq 5ac active, others without user data. SXTsq’s at 50 to 100m, plenty of power, reduction was needed.
TCP on its own has its choke points (congestion avoidance controls)
With the 802.11 protocol there is a risk for the “hidden node problem” if SXTsq’s don’t hear each other, leading to collisions at the AP.
