Where abouts in Ceredigion are you - in the North of the county?
I'm near the Southern edge (between Llandysul and New Quay).
Well - you could try a 4G router on its own, in an upstairs window is best - that may pick up a signal anyway, as the router's own built-in aerials are pretty good (at least on the MR200 that I have). And if that's not enough, then an external aerial can be added - you may need to try the router in every upstairs window, originally there was just one spot in one window I got a good 4G signal (although EE have since boosted the signal in my area) - even had to put the router on top of a few boxes on the windowsill to raise it up to get the best signal I could! I've heard some people put their 4G router in the attic, if it picks up a better signal there. I've also tested an omni-directional external antenna (on a broom handle outside different upstairs windows, ha ha!) - and it does work - I'm hoping to install it properly soon when the weather improves. But I do get a decent 20-50Mbps downstream & 2-10Mbps upstream now from the 4G connection (latency is generally under 70ms) even without the external antenna.
One thing with 4G routers - you may need to configure it to force it into 4G mode, otherwise it may use "Auto" mode and then use 2G or 3G signals instead if those are stronger.
The only thing is - it's around £100 for a suitable 4G router (like the MR200), so a bit of a risk if it doesn't work. But even if you get a 3G signal instead of 4G, it's still useful as a "fail over" backup connection, in case your fixed line ADSL (or hopefully in future FTTP!) link goes down. (Even 2G is just about usable for basic email access I guess, as a last resort - but is a bit like going back to the dial-up days!).
I believe that Fixed Wireless is usually quite a reliable fast and low-latency connection, if available. The only thing is, there's no easy way (that I know of) to find out what (if anything) is available in any given area - just a basic Post Code or map search at each company's website.
Some that I know of that *might* cover your area are:
Blue Wave Internet
Dyfed IT (aka Dyfed Superfast)
There may be others too.
I can't vouch for or recommend any in particular, as I haven't yet had any experience of them - however, our hamlet is currently trying to set up a Fixed Wireless link via Dyfed IT, so hopefully that will come to fruition soon...
Yes - I expect you could work via 4G from that camper van up a mountain!
In addition to the ThinkBroadband Mobile Forum
, another good source of information where people provide ideas on mobile & fixed wireless broadband is the ISP Review Mobile & Fixed Wireless & Satellite Forum
Hopefully this will give you a few options & ideas anyway! Good Luck!
