wifi / 4/5g on board

Don't enter into any long term 3g/4g contracts - stick to either PAYG or 1 month contracts. Coverage round the coast tends to be pretty poor and we often find that we have to change mobile network whenever we move the boat. It's very annoying to be forced to continue paying a contract when there is no signal on your mooring!
 
To some extent its going to depend on where you want internet access, ie are you mostly in your home marina, cruising and anchoring, cruising using marinas.....

A WiFi extender may be worth it if the marina has a reliable fast service that, more importantly, stays that way from onboard. I've pretty much given up on using other peoples wifi as its become too unreliable and inaccessible.

5g is unlikely to be useful onboard short term, mainly because the cells that support it are short range (10s of meters). It works by having lots of them.

So focusing on 4g, as maby says its all about the signal where you are. I've been using a simple 4g dongle plugged into a small router to provide an onboard wifi service. A downside of that is that unlimited data plans for multi device SIMS are a bit like hens teeth. A mifi is a simpler way of achieving the same end and if it has an external 4g antenna connection for poor reception areas thats a bonus.

A Giffgaff SIM provides flexible PAYG use, runs on the O2 network and isnt bad overall. In the west country you probably need EE or one of the MVNOs that use the EE network. 3 tends to get weaker the further you are from concentrations of people. Elsewhere its a bit do your own research.

In many ways, for casual use it may be better to stick with the phone SIM using that as a hotspot for other devices.

Don't know how yacht suitable they are, hopefully find out soon, but I use an external OMNI antenna Poynting 4G-XPOL-A0001 Cross Polarised 4G Omni LTE Antenna: Amazon.co.uk: Computers & Accessories and an unlocked 4G router that will take the connection. Would be nice to get a wifi extender in the same package and wire in a voltage regulator. The Wifionboard - Wifi onboard stuff looks stupidly expensive for probably out of date chipsets that the Chinese put in crackers. I have had very few true dead spots anywhere inland at least with a decent antenna.

Three have unlimited router / tethering tarrif for not very much, though their network is crappy in some locations. It's mostly good enough to use for remote working.

Wifionboard are taking the mick, that's a £30-40 OEM router and a not particularly good antenna for 600 quid. You can amazon the same router + bits for well under 200.

There are several unlimited data plans around, but most of them require a 12 month commitment - not really suitable for a boat that is likely to move.
 
There are global non expiring prepay data plans for IoT devices etc but they are not cheap for personal use. If it is for UK use mostly, an antenna really makes a huge difference.
 
Just use a phone and set it up as a personal hotspot. We’ve been doing this for some years using an iPhone whilst we spend the summer months on board. On the odd occasion when we wind up with a poor signal, we put the phone into a waterproof bag and hoist it up the mast using a signal halyard.
One iPhone will support two iPads doing most stuff except for streaming 2 videos at the same time.
 
The wifionboard stuff is up to date but stupidly expensive considering it's just Huawei stuff that you can get anywhere else

They could at least stick it in a serious looking industrial case with an anchor on it or something.

This probably costs more than most of our boats at a guess MeridianXS | Fastest Internet Onboard Superyachts. 4 £10 broadcom SoCs and a raspberry Pi in a fancy box would do it.
 
I also have a Three 2 year SIM only deal unlimited everything inc when using phone as hotspot £10/m first 6 months £20 thereafter, I live aboard FT, marina wifi is useless. Also same in 70 odd other countries. The longer we go on the less of an incentive there seems to be to fit fancy expensive wifi aerials just to get some low bandwidth wifi & the more incentive there seems to be to fit 4G(5G?) signal boosters...
 
Thanks for the advice, as becomes pbo. From hoisting my mobile up the mast to a superyacht wifi system! It would appear that the only dual system (wifi antenna and 4g sim) combination is the glomex lite.

At the risk of teaching my granny ;) ... installing that at the masthead then changing the SIM card could be... erm... interesting (even with mast steps). See if you can get a demo before you buy, just to try out the WiFi selection (hotspot manager) interface - some are intuitive, some arent

Thats what we do also - except that in some remote Scottish anchorages (where a text signal is difficult to find, let alone 2G or 3G data signal) the phone goes up on the spinnaker halyard to the masthead, in its waterproof case. The WiFi hotspot easily usable at deck level.
 
I use the Redbox solution together with the 4G module after investigating various others. It works very well. Essentially there is a central hub to which you can connect 3/4G, Wifi and Sat Phone. All sources then become available through a local WiFi connection on board with quite sophisticated control over the amount of data that can be used and from which source. It also means that everyone can share the same access point wihtout each person having to log in. Reception of the 3/4G signal and WiFi is dependent on the quality of the external antenna. The better the antenna, the better the signal. I have come to the conclusion that so called boosters are not quite what they seem. The bottom line is you can boost a signal if one exists but the key to getting a signal is having the best available aerial you can afford. I have seperate 3/4G and WiFi aerials mounted externally and realtively high up onn the arch. I reckon I can pull in a signal if anything of a signal exists, so will typically see WiFi hot spots and 3/4 G connections from signifcant distances.

I considered things like Glomex but came to the conclusion these were no more than a good 3/4G aerial (but not the best) with a 3/4 G modem built in. The advantage is the modem is very close to the aerial so signal loss in the wire is as small as possible. The down side is that changing sim cards may be much less than convenient depending were you place the dome. On the other hand the Redbox Sim unit can be placed somewhere convenient and easy to get to remote from the aerial. Using top quality low loss aerial cable pretty much overcomes the signal loss in the cable, and made good by using a better aerial in the first place.

It is not the cheapest option but very robust and probably one of the best all round solutions in my opionion if you want on board WiFi that taps in to either 3/4 G, WiFi hotspots or your Sat Phone if you have one, and enable anyone on board to connect their device and access any of these sources from one hotspot, with controls in place if needed to limit how much data they can use, or what they can do.
 
I use Giffgaff, my wife EE. As mentioned there are plenty of places in Scotland with voice only signals , never mind data!. Having two different SIMS is a major plus point, One or other phone acts as a hotspot.
I don't think we would cope with one network on its own..
Ashore - - is a very different scenario.
 
Thanks for the replies. Either of these it is then.
