Wireless Internet - Remote location.

[wireless]

I have a setup in remote location near Bashaw Alberta using the Telus LTE internet right now and am looking for upgrade ideas.
Currently the area claims to have "advanced LTE" support but this is somewhat lacking.

Using the Huawei E3276 plugged direct into laptop it gets about 3Mbit down 1Mbit up, I made an antenna setup with an wilson cell booster in line for it to the top of the house and am able to get now 18Mbit down 3Mbit up.

Its plugged into an Asus RTN66U and sees same speed right now and uses the router to deliver wifi to the few machines that need it...

Question is are there any newer devices (usb sticks or routers) that work on possibly a newer band or anything to get up the speeds to what is advertised as LTE Advanced? One with connection to external antenna would be ideal.
