5G网络可能带来新问题,你的位置不再是隐私
The fifth-generation cellular network rolling out in America and other countries this year will revolutionize the way our devices connect to the internet and to one another. 5G is such a technologically important leap forward–without it the future smart cities we dream about where everything is connected simply wouldn’t be possible. However, there is one major–and unavoidable–drawback to 5G: It’s going to cost you your location privacy. Anyone with access to your ISP’s cell tower data will be able to hone in on your exact location far more precisely than they can today under our 4G networks. The reason for this is that 4G network technology has a wide coverage area when it comes to being broadcast from a single cellular tower. Matter of fact, 4G can be broadcast about a mile from a single tower. 5G network technology, on the other hand, has a much smaller coverage area, and it can’t penetrate through walls to get indoors as well as 4G technology can. This means 5G networks will require many more cellular towers placed closer together. These towers won’t be like the old towers you envision that look like electrified Eiffel Towers, mind you, they’re just small antennas that will need to be dotted around on rooftops and street lights and inside shopping malls and other buildings. Since 5G towers will need to be everywhere and you’ll only connect to one 5G tower at a time, your mobile network will now be able to pinpoint your location much more accurately–even knowing which building you are in. |
