4G+ modem with external antenna recommendation

[Tayaout]

Is there any recommendation for a 4G+ capable modem that has external antenna?

I currently use DTAC and there is currently 4G but the signal is about +-50% on my phone. Their website say 4G+ will be available within 3 months in my area. It is already available at like 15 min driving distance.

I don't want a cellphone booster. Ideally I would like a modem that can be bridged to my OpenWRT Gigabit router via ethernet. I got many service on my LAN and would prefer to use my own router since most modem don't seem to support Gigabit speed.

I found a lot of antenna and I'm thinking about using a directional antenna. I'm not sure what to be looking for as for the modem especially the frequency and connectors needed.

 

TLDR:

1. What frequency is needed for 4G+?
2. What connector is needed for the antenna and modem?
3. Any model recommendation?

I am thinking about using a ROCKPro64 Single Board and a LTE-A card or some plug and play solution.

Doesn't make much difference if 4g is saturated at your area. Even a single antenna doesn't help to reach max speed. What speed are you getting now?

I don't think it's saturated... It'a a rural area and I get almost max speed for my package but the ping is bad because the 4G signal it at most 50% (usually around 15-20%) so an external antenna should fix this. I want to be 4G+ ready so I can choose a faster package in the future and want to go offgrid so a single board could be a nice solution.

I already think I will choose this one: http://www.banana-pi.org/r2.html with https://techship.com/products/sierra-wireless-mc7455-lte-cat6/ and install OpenWRT.

 

Edit: This one is hard to beat: https://forum.huawei.com/enterprise/en/HUAWEI-E5186-4G-LTE-CPE-Overview/thread/350483-863

Support everything I need and has SMA connector for antenna and I can get it for 2,000 baht openbox.

Dtac 4G+ network is on 2300MHz band.

Case probably closed.

Ok. I'm getting 4g+ all the time in Bangkok but max speed can't even saturate 3G+ plus speed so I don't see any point of deploying 5G when people don't even get 4G speed.

I thought 4G+ was not 5G. It's 4G LTE-A. It's not really about the speed I get now but the fact that I don't want to buy another device in 2 years.
