to find wi-fi Today, in the twenty-first century, people can go online nearly everywhere. We don't have to be at home or work or school. There are hotspots in cafés, hotels (even in the Sahara!), shops and hospitals. At the moment there are about 5.8 million hotspots in the world! Although we still can't browse online or check our emails on some planes, in deserts or in some countryside areas, there are some unusual places which do have wi-fi hotspots. The Moon Are you surprised? It's true. Scientists put a satellite and receiver near the Moon. No one is using it at the moment. But people might live there and use it in the future? Who knows? Mount Everest The highest mountain in the world got wi-fi in 2010. There are hotspots all along the difficult routes up to the top. So, if you want to climb to the very top, the summit, you can take a selfie and share it with your friends! The North Pole A Russian team made the difficult journey into the Arctic in 2005. They set up a hotspot at an ice camp eighty kilometres from the Pole. It was the first wi-fi connection in the Arctic. London black cabs It usually costs a lot to go online while you're travelling. But now you do this for free in many London black cabs (taxis). You have to watch a fifteen second advert first but then you get fifteen minutes of free w to use on your phone, tablet or laptop. Useful for the cabbies too! Engineers are still working to bring wi-fi to a lot of remote areas all the world. Small African villages might soon have wi-fi, just like the big hotels! 56 Unit 4
