WG3526-P Router w/Sierra MC7455 Modem inside a DM25X19 Antenna

Just curious, but run the following commands, and show the results for each one:

Code: Select all

at!entercnd="A710"
at!usbcomp?

Code: Select all

at!entercnd="A710"
at+cgdcont?

Okay, so I have finally got it setup, but the speed is abysmal...

I ran the commands you requested and here is the outcome.

Okay, now run:

Code: Select all

at!entercnd="A710"
at!gstatus?

And lets look at your signals

5MHz B26, ouch. That is gonna be an issue. Total peak bandwidth on a 5MHz carrier in 2x2 MIMO is ~37Mbps.
See: https://frankrayal.com/2011/06/27/lte-peak-capacity/

Your SINR and RSRQ are also very low. So the fact that you are getting terrible speeds is not at all surprising. You have about the equivilent of 1-Bar on the normal cell phone.

AT!LTEINFO? would be great to see while you are still connected.

Lets kill off B26 and see how that works for you:

Code: Select all

AT!ENTERCND="A710"
AT!BAND=10,"B25+B41",0,0000010001000000
AT!BAND=10

To undo band locking:

Code: Select all

AT!ENTERCND="A710"
AT!BAND=00

I am curious why you put the router board and modem into the antenna enclosure?

seems having the router and ports inside the house would save from buying another router? just asking. great write up. I am strongly considering doing this as my zte warp is really slow, and tired of buffering all the time.

doing research before I place my order to understand everything.

Short version: LAN cables are cheaper and more efficient than antenna cables.

Longer: The router is the place the modem is installed and interfaced. The modem is where the antennae are plugged in.
Antenna cables arent cheap and degrade quickly over length without spending a large sum on cables and equipment.

Since the modem and router are in the
housing, I only need 8" antenna pigtails. LAN cables can redily carry a good signal cheaply and with low losses over decent length.

I use a separate router simply because Im too lazy to configure all my wireless devices to the new router.

Thanks for the response. that was my guess, but wasnt sure...

Now, do you have any concerns about the equipment being exposed to temp extremes? I live in michigan and see -40 degrees to 100 degrees. should I be at all concerned about that with the router or modem hardware?

[Didneywhorl]

I doubt cold is a problem with any electronic. Heat has been well over 100F here and Ive zero issues.

Hi, thanks for the thorough tutorial!

What if one wants to build a system with the EM7565? Can the same router and antenna be used? If not, what options are available?

Realistically, would the speeds be different, or is the MC7455 not the bottleneck of the setup? My provider is Sprint (through Calyx) if that matters.
