【題目】 The network technology in your mobile phone is the result of years of development in wireless communications. It is called 2G, 3G, 4G and now 5G. 5G networks have been treated as the next big thing for wireless users. They allow people to get __, with videos that will start to play immediately and information downloads that will take only seconds, instead of minutes.
But no true 5G phones are able to be used now. Motorola has produced publicly the first 5G smartphone, the Moto Z3. But the problem is that 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. But when to use 5G directly is the point.
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. Cord-cutting has become popular and common. Many users are tired of spending $100 or more monthly in booking cable (有線的)TV. They don't choose cable TV any more and begin to use streaming (在線播放) services connected to their broadband (寬帶)service instead. The U.S. communications company Verizon has developed home broadband for its 5G tests and has decided to work together with Apple TV. Another U.S. top communications company, AT&T, now is the No. 1 broadband provider in the United States, tested 5G in nine markets in late 2018.
Besides faster access, connectivity might get a little cheaper in the future for users as long as 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 for now, it's all about the home. How will 5G develop next? What will 5G bring to us? Let's wait and see.
