5 gadgets that could make Brazil 2014 the best World Cup ever

Fifa World Cup Brazil

With the World Cup nearly upon we are going to look at 5 technologies that will be used in the tournament.

The 2014 World Cup kicks off tomorrow and what better way to wet your whistle than to read about 5 gadgets that will help to make this year's tournament one of the best and most efficient ever.

1) Goal-line technology

Brazil 2014 is the first time ever that goal-line technology will be used at a World Cup. It has been a long-time coming but this kit really is imperative to the modern game; in it's debut season in the Premier League it has proved crucial in determining whether the ball has or has not crossed the goal-line.

It's called GoalControl and all 12 stadiums in Brazil will be equipped with the technology that requires 14 precisely positioned cameras, 7 on each goal, to be recording at 500 frames per second. Whenever a goal is scored the referee will be alerted by a message on his watch saying "GOAL", very simple.

Refs and linesman have taken a lot of flack for disallowing legit goals, most notably the 2010 Lampard vs Germany incident, so this new bit of kit will make their job easier and make the games generally run smoother.

2) Brazuca most high-tech football ever

After the controversy of the 2010 Jabulani, Adidas tore apart their plans and designed the Brazuca completely from scratch. The Jabulani's problem was that its eight patches and seams were poorly designed and this made it 'knuckle' and much higher speeds than expected.

Adidas have solved this with the Brazuca by constructing it with six propeller-shaped polyurethane patches that are bonded by heat, rather than sewn together. The ball's seams are also deeper and more elastic than any football before it.

Research says that an average ball knuckles at 30mph, the Jabulani knuckled at more than 50mph. Fortunately for this year's World Cup stars, tests on the Brazuca reveal that it knuckles at the same speed as an average ball.

3) Vanishing spray

This one might be news to quite a few of you, it certainly was to me; every referee in Brazil will be equipped with a can of vanishing spray.

What it does is if a free kick is awarded precariously close to the penalty area, it will allow the referee to circle where the ball should be placed, and then walk the 10-yards and spray a line where the corresponding opponent wall must not pass.

It's a water-based solution that closely resembles aftershave, and one minute after it is sprayed it disappears; the spray is already tried and tested after it appeared in last year's under-20 World Cup (see picture).

4) 4K broadcasting

Sony and FIFA have confirmed that three 2014 World Cup matches will be broadcast in the new eye-dazzling 4K, or otherwise known as ultra-high definition (UHD). 4K resolution transmits 4,000 pixels by 2000 pixels, which is enormous. It will offer incredible picture quality and detail, and will probably look as if you’re actually at the match itself.

If you don't know what 4K looks like then just go to the cinema, as 4K is currently the standard for cinema displays around the world. Anyone lucky enough to own a very expensive 4K ready TV or live near a selected cinema will be able to immerse themselves in the tournament, whilst the rest of us are stuck with 1080p.

5) WiFi hotspot galore

Those fans, pundits and players who are in or travelling are to Brazil will be able to stay connected almost everywhere they go, thanks to the huge number of new WiFi hotspots set up especially for the competition.

Brazilian Telecoms giant Oi is FIFA's official partner for the World Cup and they have increased their number of hotspots from 78,000 to an incredible 700,000 in the space of a few months.

So if anyone in Brazil reads this remember to switch off mobile data and only use WiFi, network providers will charge £5 for every MB of data used in South America.
