题目内容
【题目】 5G networks have been considered as one big thing for this century. They allow people to get faster services. Downloading information takes only seconds, instead of minutes.
But no true 5G phones are able to be used now. It won’t work with 5G until such services are built. Users will need an adapter to bring in 5G signals. There’s completely no need for users to worry about the safety of 5G signals.
Where will we probably see 5G first? The answer is in our living rooms. The speeds, about 20 times faster than the standard home Internet connection, are very likely to do wonders in our living rooms. Many users are tired of spending $100 or more monthly in booking cable(有线的) TV. They no more choose cable TV and begin to use streaming(在线播放) services connected to their broadband(宽带) service instead.
Besides faster access, connectivity might get a little cheaper in future for users only if a complete 5G network is set up. However, the cost of programs and apps will go up. Meanwhile, users are in great need of ordering more monthly services. Comparatively speaking, users are likely to pay more for 5G services.
So far now, it’s mainly used at home.
