Getting too technical now guys....dummies terms please.
I will try.
Will a boost system take up more bandwidth than a non-boost connection? No
Will a boost system provide faster download speeds? Maybe
If you are at a distance where you are experiencing data loss then you may see better throughput through a boost. However the tablet, PC, phone you are using to connect with will also have a huge say with the speed of your on-line experience. Additionally you sometimes find the longer you are connected the slower your connection will become. This is how some networks in the UK are set up, let the punters think this is really fast when they connect and them send them down the pecking order when new connections arrive.
Can Campsites, WiFi hotspots,etc see if you are using a boost and block you? Yes
A lot of WiFi providers use Ubiquiti Networks to provide the service. iBoost is a Ubiquiti Nanostation Loco M2 with a sticker on it. This will show up on their management software as a Ubiquiti client. Currently this is a rare event, we have been blocked twice in Spain and once in Greece.
What is 5G and 2.4G?
This is the bandwidth the signal is being broadcast over. Normally 5G is used within buildings but we have seen two campsites using it. The reason is to sell you a system and stop you using boost systems. I doubt this idea will catch on.
Shall i buy a boost system? Depends.
If you primarily stay on campsites then probably yes. But i wouldn't spend much money on one. The reasons are you will be mostly connecting to slow, non-secure networks. You should never use one to transfer any private data over. Cellular is the way forward if you tend to move around and not stay on campsites. Mobile phone service is far superior once you leave the UK. We normally now connect to 4G and only in remote places does that drop to 3G. You will get a shed load of fast, secure data for the money you pay for a boost system. Also if you have to keep buying coffee to get passwords then you must factor that into your costs.
A Huawei E5372 MiFi does both. It is a router that connects to 4G and Wifi and so covers both bases. You can also add an external aerial to it to extend the range. it is not as good as a boost on Wifi but it is not bad. On Cellular it connects at up to 150mb, that is 50x faster than most campsite WiFi.
If you plan to buy a boost then look for a Ubiquiti nanostation Loco M2. Should not be more than about £40. This is used by every RV owner in the US, every leisure sailor around the world. If you do this set the country to United States and it will have twice the power of other boost systems. it might make your hair fall out and fry children from a 100 yards but it will allow to connect to systems a lot further away. You could also try a bear extender, especially if you are a Mac user.
Hope this helps
