Had a look at
Mikrotik SXT LTE
You can mount this outside on a pole high up for better signal or,like i have ,in your attic
READ the advert carefully though as some come `without` a 4g card and `some` have a wifi card too
No SXT LTEs come with WLAN. SXT is Mikrotik’s designation for the housing shape. That’s all. There are a multitude of SXT models. Some of which are 802.11bgn, some are 802.11a, some are even 802.11ac but only the SXT LTE and SXT 4G comes with a WWAN modem built in and they don’t support WLAN by themselves. They need a separate access point.
Make sure you buy the newest CAT6 SXT LTE as it does 2G, 3 G and 4G data over all bands worldwide with carrier aggregation if available. The older LTE CAT4 only supports 4G up to 150Mbps against 300Mbps with the CAT6 device. Do be aware though that EE ‘charge’ you double the used data against your allowance if you use the carrier aggregation function.
And don’t buy the SXT 4G kit because it only has a 4G modem, it can’t drop back to 2G or 3G if the 4 G signal goes off.
One major benefit of running with Mikrotiks hardware platform is that it’s relatively straightforward to upen the up and replace the old 3G/4G/LTE modem mini-PCIe card with the newest one. And should apply to 5G as well, assuming it doesn’t need a completely different antenna setup.
If you want something a bit less extreme that does have WLAN built-in then look at Mikrotik Audience LTE or if you want the most extreme LTE solution then Mikrotik LHG LTE could be what you’re after. There is a recent thread on here from
@bledd (who knows his stuff) where he used a Teltonika LTE modem/router/AP with great success.
