For those that have a Grandstream GWN7610 AP, can you tell me the list 5 / 5.8 GHz channels available.

 

Very tempted to get one.

 

Thanks!

I have one but am at work right now. I'll post back tomorrow morning sometime unless someone else beats me to the punch. If it's any use, here's a link to a datasheet.

Frequency Bands

 

2.4GHz radio : 2.400 - 2.4835 GHz
5GHz radio:   5.150 - 5.250 GHz, 5.725 - 5.850 GHz
Exact channels probably depends on the Country set.

michaelmurfy: Also if you want more temptation my review on the kit is finally up: https://www.geekzone.co.nz/content.asp?contentid=21647 

 

@AKLWestie - the review posted by @michaelmurfy has a screenshot showing the exact channels for both bands under the Features heading.

I have it operating here (NOT NZ). On the screenshot you only see the "WiFi channels of the world". This does not necessarily mean that they can be really selected in the setup according to your country settings. For me, only 4 out of them can be selected regardless the fact, that we have 19 channels in the allowed ranges by means of law (and some more). This was identified and verified by using the WiFi analyzer app. Opened a ticket with Grandstream.

 

 

 

edit: They replied that the DFS channels are NOT supported for now as I already menioned in another post assuming the bigger effort to protect those weather radar frequencies (worldwide). They are working on it but there is no ETA date for. I they would not, we would be limited to a very narrow channel setting having in crowded environments the same overloaded situation as in the 2.4GHz band with no real gain because many "cheap" consumer APs and routers haven't implemented this as well.

Did you have a product for your country or a US market AP? Products sold in or for the US market aren't allowed to function on non US frequencies.

I have an international model with no specific market assignment operating in Germany (under EU harmonised rules). Grandstream replied already (see my edit, I found it a few seconds before in my mailbox).

@Dratsab and @Tinkerisk, the narror bands of officially supported frequencies/channels is a concern.  5.150 - 5.250 GHz, 5.725 - 5.850 GHz mean channels 36, 40, 44, 48, 149, 153, 157, 161, and 165.  Which are not that many.  In NZ, on top of those channels, we can use 100 to 144 (an additional 12 channels).

 

@michaelmurfy, thanks for the review.  Would you mind to try how many 5GHz / 5.8GHz channels you can use?  The screenshot lists a lot of channels but I am not sure whether all can be used.

 

Thanks!

I don't have the GWN7616 anymore - that has been handed to @Dratsab :) You honestly won't have any issues with it. Go grab one!

If you look at the picture posted by Mike in his review which I directed you to, you'll see the AP lists channels 100-140 so 11 of the 12 additional channels you mention above. Also in his review Mike talks about being impressed with the wifi performance in a 2-storey house - the house is mine :-) 

 

I'll see what I can do about forcing devices onto various bands tomorrow morning and will post back.

There are only 6 non overlapping 80mhz 5ghz channels available in nz anyways. 29 non overlapping 20mhz ones.

It seems they have currently implemented IEEE 802.11j (Japan) only. Four channels 36, 40, 44, 48 here we can have additionally the channels 52, 56, 60, 64 and beside this as you 100-140 (but not the channels above) and that's exactly why I opened a ticket Grandstream replied "working on that, no ETA date at the moment" with. I think it's "slight" difference only to have 4 channels instead of 19 (in my case).

 

 

 

As technical background they can't simply adjust the country selector setting in the AP setup. You need to know the fact that everything above channel 48 one have to take mandatory measures to protect the weather radar (channels 120-128 plus some protectional space below and above) against distortions form WiFi using "DFS" (Dynamic Frequency Selection) and "TPC" (Transmit Power Control) and vice versa. This effort is often tried to be prevented by WiFi manufacturers. Beside that you might know 5GHz is definded to be only allowed "inside buildings" (theoretically).

 

There is a risk identified that due this lack of frequency use by manufacturing, some mobile service provider try to claim more and more for those frequencies because they don't fear for sure the effort to get even more room due to implementation of DFS and TPC (at least that's the case here)!

 

One could think as a workaround just select another country and tackle the relevant channel to be used fixed instead of automatic frequency hopping. But this won't work when the desired channels are not implemented in any country.

OK - finally got round to it. Below are the selectable channels on my GWN7610 - none of the channels between 52-140 appear in the list so I guess they're currently out of bounds as per the discussions Tinkerisk has had with Grandstream. Perhaps USS michaelmurfy could raise a query through his contacts in Go Wireless around this to see if there's any update on when some of these channels might get supported/enabled.

 

I'm certainly not experiencing any issues but, to be fair, I'm not in a high density housing area with [potentially] lots of competing signal.

 

 

EDIT: added a word.

It is just simply missing the DFS channels - the channels are the same as the UniFi for example. I would never use the DFS channels anyway and normally disable them from every WiFi installation I do.

DFS channels are useless since device support isnt universal. Perhaps in a high density environment where devices that can support it can be pushed over to those ones freeing up the other channels on different APs, but for home use I had about 3 things connect to the DFS AP's when I had some on them. All the speakers, alexa, chromecast etc would just hang onto an ages away normal channel AP since no support for the DFS.
