CDMA is the best signal, his network is close to 3G, and the connection has put a lot of effort into laying it.
In fact, no matter whether the signal of any network is good or not, it mainly depends on how many relays it has in one place. In wireless browsing services (e.g., WAP), CDMA is many times faster than GPRS.
-
The signal is very good, especially on the sea, where there is no signal at all.
-
Very reliable.
It's just a bit of a messy charge.
If you use CDMAIt's better to wait, it's a year and a half to plant.
The next generation of mobile communications --- the 3G era, and when it comes out, CDMA may not have anything. However, low radiation is better, and women are the best.
-
CDMA mobile phone signal is the best in Unicom.
Advantages: fast Internet speed, convenience, low radiation.
Cons: The signal is not very good (and moving).
-
In large and medium-sized cities, the signal is about the same as the movement.
Mobile phone radiation is relatively small.
-
Compared with mobile and telecommunications, mobile signals and networks are slightly better.
If you're in a city, mobile signal is a little better than telecommunications, but if you're close to the suburbs, telecommunications is better than mobile in many places. In terms of network speed, the signal of the 4G base station is basically the same, and there will be no obvious difference? In the south, there are many cities where telecommunications are better than mobile signals.
China's three major operators:
1. China Mobile, the 4G base station of domestic mobile has reached 2.41 million, the mobile signal is relatively good, and the coverage range is very wide, which is the best mobile to do.
2. China Unicom, the number of Unicom's 4G base stations is 990,000, and China Unicom's signal is not as good as China Mobile, sometimes even inferior to China Telecom's, and the coverage is not extensive. In this regard, China Unicom is no match for China Mobile and China Telecom.
3. China Telecom, the base station of Telecom is 1.38 million, and the signal of Telecom can be said to be the worst, but the coverage of Telecom is very wide. In some remote areas, China Unicom and China Mobile may not have a signal, but Telecom does have a signal.
Causes of slow network and poor signal:
1. The performance of the mobile phone chip If the performance of the mobile phone modem is relatively poor, it will affect the signal of the mobile phone. Only when the mobile phone has a good quality of receiving signal can it achieve good network speed and sufficient signal effect. The reception of the signal depends on a special set of chips in the phone, the modem.
The baseband chip of a mobile phone is used to encode and decode signals when receiving and sending them. The baseband chip is the translator, and the speed at which the mobile phone receives and sends information also depends on the efficiency of the translation.
2. The performance of the mobile phone itself has deteriorated, and it is very likely that many people will feel the slowdown of the online speed after using the mobile phone for a long time, which is actually the overall performance of the mobile phone itself has decreased, so that the application feels poor, and then it endangers the speed of online knowledge and blocking. There will be an automatic running of apps on the phone, which takes up a lot of storage space, which also endangers the running rate on the phone. There are also some apps that have long been closed and are actually running secretly in the background.

It mainly depends on what brand you buy.
Now it's mainly a few brands of Samsung Coolpad Guangxin, which are not bad, whether they are used for calls or surfing the Internet, they are very good.
There are also a lot of other copycat phones, it still depends on what you think.

Signal, of course, there is no need to say, CDMA is safe and radiation-free, the signal is strong, but the Internet is not very good, the tariff is too expensive, as expensive as using the computer, calculated by the hour, there is a monthly subscription can not be compared with the mobile, the difference is too far, people who like to surf the Internet can not use telecommunications! It's said that it's strong, that is, a domestic mobile phone, and it's generally okay.
-
I can't be sure whether a certain mobile phone signal is good or not, I can only say that sometimes the signal distribution in the place is not strong, and Nokia's signal is in a general place, which is quite okay.
-
As long as the signal of the network is good, the signal of the mobile phone is good, and the quality of the signal has little to do with the mobile phone. Because the principle of mobile phone antennas is the same now, it has always been recognized that Nokia has a strong signal, and I hope to adopt it!!
