If you have the opportunity, the device page in particular could use some “freshening up”. If you send me some higher res photos I will upload them and add them to the pages (min 640x480; max 1280x720, max 1MB). Please send 3 minimum, outside, and interior of board both sides. I think you have my email.
@Jeroen, yes, there will be antenna-version, PoE verion. So each product will have 4 models (Standard, Ext, Standard-PoE, Ext-PoE). I hate this very much! Please allow some time to make them available. PoE can be just soldered, but for Antenna, it should be hard-cored during production.
@unmesh59, we build our own repo. You cannot install kernel packages if you use the repo from openwrt. But you can install applications without problem. Both repo you listed above works.
I thought GPIO numbers would start with 1. So it would be GPIO1, GPIO2, GPIO3, etc. Appearantly it starts with 0 (zero) and that’s the one for the USB.
As for the different GL-MT300N versions: I can imagine it will be alot of work to maintain the different versions. Isn’t it the best to have the PoE default on the board? And do a poll for whether the antenna’s needs to be always external or not? Both can save you a lot of work I think.
I don’t know that’s OK… What would be the inpact of the WiFi range?
I want to try to use the GL-AR150 with the long antenna within a big party tent on the sports field durin a yearly big sports event in my town. I’ll need a coverage as big as possible right there. I don’t know a 2 dBi will cover the whole sports field, but I don’t know this about the 5 dBi either. I’ll have to try that someway, somehow, sometime.
@alzhao You mention the antenna needs to be “hard cored” Does this mean the External antenna I ordered with my MT300N router won’t fit? I thought there was a u.FL connector on the board that can be used to attach the external antenna (from the diagram)?
I understand now why we can’t just plug in the cable.
The connector on the board is there, but it’s not u.FL.
The connector is a test probe connector, it passes through the connection but allows a probe to be inserted for testing, but you cannot attach an antenna to it. This is the connector on the board;
It would seem, that to connect the external antenna, you need to de-solder this connector and then solder on a u.FL. I’m not sure the effect having this connector has on the on-PCB antenna, but I suspect it would not pass-through the signal so you MUST have an external antenna connected. Perhaps alzhao can confirm?
My earlier confidence on replacing this connector has somewhat waned having received the router and realising it’s MUCH smaller than I anticipated I’m going to need a much finer Soldering iron tip.
@alzhao can you please give the model name/number of the u.FL connector we need for this?
Thanks for your research Hamid. This is starting to make sense now.
I think our answer (though rather cryptically lies in this earlier post I just found :
Like you, I also had virtually heated up my soldering iron to set to it but might have to squeamishly bail out now for the same reasons
As Alfie already mentioned in a post earlier in this thread, we may not like that we cannot simply plug or unplug an external antenna whenever we feel like it and make it fall back to the PCB antenna. But it seems that it is not that easy to have both, from a design and engineering standpoint.
I lack too much RF knowledge as well to make any valuable comment in this matter.
I have a background in Electronic Engineering but nothing in RF I’m afraid. The hirose datasheet for the connector we need is a bit cryptic but it appears that the connector does not pass through the signal, so once it’s soldered, the PCB antenna is no longer connected.
The only way I had imagined it working is if the hirose connector could act as a switch, and switch between the external and internal when the external connector is inserted. Again, from the datasheet this appears not to be the case, and understandably so given its size.
To leave both connected would affect the signal as it’d be leaving via two different antennas at once. I’m not sure if there’s a possibility of having two small jumper pads on the PCB letting you disconnect the PCB antenna if you wanted to connect an external, and have the u.FL conenctor there ready just in case. You’d just join them with solder to connect it back.
