Is PHS a mobile phone or a landline, and what is Telecom PHS?

PHS can be thought of as a wireless landline.

Its working principle is exactly the same as PHS, the difference is that PHS uses mobile phone mode, while PHS is landline mode.

PHS charges the same as PHS, such as monthly subscriptions and the like, so the performance ratio is very high.

But now that PHS is a thing of the past, PHS is gradually gone.

The original PHS machine is not inserted in the back of the card, and a string of text in the machine is directly used to bind a ** number, and PHS will charge by inserting the card, just like the card of China Mobile and Unicom.

A mobile phone card is a tariff for mobile travel.

1. PHS is the mobile ** business of fixed network operators, which is the common name of CDMA450, and is named PHS compared with PHS. Later, SCDMA 400 was also known as PHS, SCDMA PHS has been built in most cities in China, while CDMA450 PHS is only built in remote areas of China.

2. CDMA450 is a technology that works at 450MHz and takes CDMA2000 as the core. SCDMA 400 is a 2G version of TD-SCDMA that works at 400MHz and is China's 3G standard. The former China Netcom applied to the Ministry of Industry and Information Technology for the 1800MHz SCDMA frequency band.

Because SCDMA technology has its own independent frequency band. Therefore, in 2008, the Ministry of Industry and Information Technology issued a withdrawal from PHS, which did not include PHS.

Lingtong is a service launched by Mobile, and there is no charge for entering the mobile network, and outside the network (Unicom, fixed**) is entering the yuan minute, and the yuan is played for the minute.

PHS is a wireless local phone service launched by China Telecom, as the name suggests, the charging standards are charged according to the fixed ** fee, and there is no roaming for the time being.

PHS Compared to the current PHS, CDMA450 gets the name PHS. At present, CDMA450 has been more widely used abroad. In China, only a few remote areas may be able to build.

CDMA450 is a technology that operates at 450MHz and takes CDMA2000 as its core. Initially, the CDMA450 was developed to upgrade the NMT450 analogue mobile communications system, which was widely used in Eastern and Northern Europe, to a digital mobile communications system that supports multi-application applications. Moreover, the CDMA450 technology itself has the characteristics of low frequency, wide coverage, good indoor penetration coverage, large capacity, and support for wireless high-speed packet data services.

In 2001, after a series of technical comparisons and scheme demonstrations, ITU-D Thematic Group 7 finally found that the CDMA450 scheme was the best choice to solve the problem of users' scattered regional communications.

Compared with CDMA800 1900, CDMA450 only replaces the RF module, which is not fundamentally different from it in terms of technology, and ** is almost the same. But the difference is that the CDMA450 covers far more area per base station than PHS and CDMA2000. Theoretically, the number of base stations required for CDMA450 is 1 6-1 8 for high-frequency (above 1500MHz) systems.

From a technical point of view, the evolution from CDMA450 to 1XRT, EV-DO and even EV-DV is a clear path for 3G evolution.

Telecom mobile** some places the signal is not good!

It's about the same as PHS, and the fee is cheap

1. Distinguish by different subjects.

1. Landline: It is a terminal device that transmits voice in both directions through electrical signals.

2. PHS: It is a personal handheld wireless system.

Second, it is distinguished by the difference in the original excavation.

1. Landline: A communication technology that converts sound energy and electrical energy to each other and uses the medium of "Yu Qidian" to transmit language. The simplest form of communication between two users is to connect the two ** machines with a pair of lines.

2. PHS: Using micro-cell technology, wireless coverage is achieved through micro-cell base stations, and the user terminal (vertical wireless local phone phone) is wirelessly connected to the local network.

3. Distinguish according to different characteristics.

1. Landline: According to the voice vibration, the carbon particles vibrate, and the carbon particles conduct current, and with the degree of contact of the particles, the resistance changes, and the voice current is generated.

2. PHS: PHS has low power consumption, very little electromagnetic radiation, and less harm to human radiation, which is loved by some special groups, such as the elderly, pregnant women, and medical personnel.

The Hong Kong movie "PHS" was filmed in 1992 and starred Lin Jianming, Wu Gang, Huang Yishan, Li Lili, Yu Qixia, and Liu Tianci.

If you are unable to check the call details, you can follow the instructions below:

1.If you click on the query details page and it cannot be displayed normally, it is recommended to change the Internet Explorer browser to query;

2.If you are using a random code to log in and cannot query the call history, you can log in with the service password instead.

3.If you are querying the records of Lao Cong who has just finished the call, since the bill is not issued in real time, you can check it later or wait for the bill to be issued.

4.The online business hall only provides the call details of the past six months to check whether the time you selected has exceeded the time limit;

5.From the 1st to the 2nd of each month is the billing period, and if you cannot inquire during the billing period, you can inquire about the details or bills from the 6th;

6.Your PHS number does not support online call details.

If the above reasons have not been resolved, it is recommended that you contact the place where the number belongs to Unicom Zen Service for verification.
