Investments to move to stop new 2G network, Unicom may also want to find out. Stump retired from the stage at a future 2G, everybody must be opened 3G/4G package? Moving to stop new but continue to optimize 2G network news has been confirmed, EDI is still anecdotal. But from the big trends, stops new 2G network has become a necessity.

Why stop new 2G network?

Transition from 2G to 3G and 4G, is the Ministry and major carriers would have to develop a good strategy. At present, the room 2G base station in urban areas, increase of 3G equipment, namely, 2G and 3G share the same physical unit. Due to the 3G of a single base station coverage is less than 2G, so in addition to increased 3G in 2G already at the site of equipment, operators of this additional new 3G base station and, therefore, in the long run, the 3G number of base stations will exceed 2G.

2G network earlier, now from urban to rural, basically got covered. Operator increased the base station's power only two, one is to cover a greater area, but more user access. Currently covers 2G on no problem, increase user access, new subscribers with the popularity of 3G, 4G, 2G will gradually reduce or even negative growth, so stop new 2G base station is the inevitable choice of carriers.

2G will be repealed? Short not long term, very likely.

Why short term will not stop the 2G service?

1, there are a large number of 2G users, 2G and old users migrated to the 3G and 4G, also need more time and more favourable rates;

2, 3G, 4G, cover is not sufficient. In some rural and remote areas, there is only 2G network. Before the 3G arrive, could not stop the 2G service. Operators last year has turned on the "turmoil in the countryside" programme is to speed up the advancement of the 3G network to rural areas;

3, technical issues still to be resolved. Mobile 4G network, 2G network support during voice calls. Currently moving in positive tests is done via 4G network voice and data services, but before the full realization of this technology, 2G network also could not stop.

Why the long term are likely to repeal 2G?

Because the operator has the advantage.

1, band resources. 2G network 900/1800MHz band, and is very high quality, its coverage is better than the current 3G and 4G band. Once the 2G has completed the migration, this portion of the spectrum is released, will bring good to the 3G and 4G network support a PHS band was the staring red eyes, not to mention the 2G;

2 physical space, base station. Once the 2G network, equipment removal, has more free physical space to accommodate new equipment. Mobile base station siting are finding it harder to machine room space becomes more and more valuable, so 2G back net benefit will be deployed for the 3G and 4G;

3, optimizing maintenance costs. Although the 2G are no longer new, network optimization, and maintenance is to be done. Base station antenna for long aging, needs new, this was cost. If 2G quit, operators will save you a lot of optimization and operating costs;

4, the user migration. If you are at the right point in time to stop the 2G network, users migrated to the 3G and 4G, it would be possible to enhance the operator's data revenue. 2G network does most of its business is sound, 3G, 4G are the main hosts of the mobile Internet. Allow users to migrate to high-speed Internet, richer services may only be used.

Of course, these changes are permanent. Now, in five years or even longer, will be the coexistence of 2G, 3G and 4G.

用2G网还能不能愉快地打电话了？

中移动要停止新建2G网络的投资了，联通可能也要这么搞。难倒今后2G网络会退出舞台，人人都要开通3G/4G套餐吗？移动停止新建但继续优化2G网络的消息已得到证实，联通的目前还是传闻。但从大趋势看，停止新建2G网络会渐渐成为一种必然。

为什么停止新建2G网络？

从2G过渡到3G和4G，是工信部和各大运营商早就制定好的策略。目前，市区内的2G基站机房里，基本都增加了3G设备，即2G和3G共用一个物理单元。由于3G单一基站的覆盖面积小于2G，因此，除了在已有的2G站址增加3G设备外，运营商们还需要额外新建3G基站，因此，从长期看，3G基站数量一定会超过2G。

由于2G建网更早，目前从市区到农村，基本都实现了覆盖。运营商增加基站的动力只有两个，一是覆盖更大区域，而是满足更多用户接入。目前覆盖上2G基本没有问题，增加用户接入方面，2G新入网用户随着3G、4G的普及势必会逐渐减少，甚至出现负增长，因此，停止新建2G基站是运营商的必然选择。

2G网络会被废除吗？短期不会，长期看，很有可能。

为什么短期不会停止2G网络服务？

1、还有大量的2G用户在，2G老用户迁移到3G和4G，还需要更多时间和更优惠的资费；

2、3G、4G覆盖还不足。在部分农村和偏远地区，目前还只有2G网络。在3G到达前，不可能停止2G服务。有运营商去年开启了“农村风暴”计划，就是为了加快3G网络向农村地区的推进；

3、技术问题还需解决。目前移动的4G网络，在语音通话时还需要2G网络支持。目前移动在积极测试全部通过4G网络完成语音和数据业务，但在这一技术彻底实现前，2G网络还不能停。

为什么长期看有可能废除2G？

因为对运营商有好处。

1、频段资源。2G网络的900/1800MHz频段，是非常优质的，其覆盖范围好于目前的3G和4G频段。一旦2G用户完成了迁移，这部分频段被释放出来，将会给3G和4G网络带来很好的支持；一个小灵通的频段都被各方盯着红了眼，更别说2G的了；

2、基站物理空间。一旦2G停网，设备拆除，就有了更多空闲物理空间，来容纳新的设备。目前移动基站选址越来越难，机房空间变得越来越值钱，因此2G退网，将会为3G和4G部署带来好处；

3、优化维护成本。虽然2G不再新建，但网络优化和维护还是要做。基站天线用久了会老化，需要换新的，这都是成本。如果2G网络彻底退出，运营商将节省一大笔优化和运营费用；

4、用户迁移。如果能在合适的时间点停止2G网络，让用户全部迁移到3G和4G，将有可能提升运营商的数据业务收入。2G网络的大部分业务是语音，而3G、4G才是移动互联网的主要承载。让用户迁移到高速网络，才用可能使用更丰富的服务。

当然，这些变化都是长期的。目前来看，在五年甚至更长时间里，将是2G、3G和4G共存的局面。
