The 3G and 4G mobile network platforms provide a way of providing high-speed internet access to mobile devices like smart phones or dedicated 3G/4G products and is a convenient way of accessing the internet where there is no available presence of a broadband line.
The main discernible differences between 3G and 4G (LTE) are the speeds of data transmissions from a device to the network mast (and the resulting reply) and also the way in how 3G and 4G signals are transmitted.
3G is single stream and 4G (LTE) is dual stream which means that two signals are sent out and two signals are expected to be received.
This is what ultimately gives 4G the edge in speed over the data transfer of 3G signals as more data can be sent in a single transmission. Continue reading…
Wireless networking typically uses the unlicensed 2.4-2.5GHz or, more recently, 5.1-5.8GHz frequency band though the 2.4GHz is still the most popular form of radio based networking. The range of kit is massive with many hundreds of competitive kit available from simple USB cards for notebook computers up to powerful bridging units designed to link buildings.
Before the 802.11b protocol appeared in 1999, LAN networking meant you had to be physically connected via a cable. The family of 802.11 protocols are made up of an arrangement of over-the-air modulation techniques that use the same basic principles. The most widely used protocols are the 802.11b, 802.11g and 802.11n for 2.4GHz networks and the 802.11a, 802.11n and 802.11ac for 5GHz networks.
802.11 Operating Modes
Infrastructure Mode is used when there is at least one Wireless Access Point and client. The client connects to the network through the Access Point. So, for two clients to talk to each other they do so by routing through the access point. Continue reading…
Back in the day we thought nothing of putting up a two man tent and slumming it for a few days watching the motor racing at Silverstone or the Superbikes at Cadwell Park. As we have got older our camping needs have changed. The 2 man tent is being eaten by mice in the back of the garage and we now have all the creature comforts that come with having a Motorhome. We still love rural camping and think nothing of heading out into deepest darkest Yorkshire to get away from the hubble bubble of real life.
Caravan and Motor-homing life is very different now though from when we first started out. Often you see BBQs that are powered by gas, most people have an electric point for the kettle, even those in tents! And yes, I will admit it; I have taken my hair straighteners on one or two occasions!
We all take different gadgets with us to make life easier but one of the overwhelming things in recent years that people have wanted, when camping, is the Internet! We are all about the big outdoors, hiking, cycling going to the village pub for steak pie and a pint but when we hang up our walking boots at the end of the day and get tucked up in our ‘vans and tents we want to watch the tele, update our mates on Facebook, tell all our twitter followers how many sheep we saw or just check out the local tourist information website to see what to do tomorrow. How can we do this though? There is no phone signal; we are in the back of beyond!
Does your games console/TV/set-top box have Internet capabilities allowing you to use iPlayer, 4OD or other Internet services through it, but you don’t have an Internet connection near to it? A simple pair of HomePlugs can get your TV online in seconds.
Many of the latest ‘next generation’ games consoles, TVs and set-top boxes – besides providing new ‘High Definition’ experiences – offer additional Internet powered features; some of which were previously not even possible on devices like these.
Loch Ness Castle Lodges comprise a number of separate Individual and High quality houses and log cabins situated on the banks of the River Ness close to the highland capital city of INVERNESS. The houses comprise an original Stone built house with 4 substantial Log cabins over an area of about 1 km along the banks of the river ness. After suffering appalling broadband access (the telex is 6km distant) and having attempted to use mobile broadband with very poor results, Simply WIFI were approached to provide WIFI broadband access to the lodges.
Given that the normal means of ADSL provision had already been tried Simply WIFI surveyed the access for satellite broadband access and although the situation was tight there were some positions where the ground station could see the satellite. The bothy roof was chosen as most desirable position considering weather and access. The Tooway satellite broadband gave the site broadband access at up to 20MB download and 6MB upload, far superior to that which had been achieved to date.
