EDGE wireless Internet access

Wireless Internet access can be achieved in a variety of ways, such as surfing on the wireless network. Next, we will give a brief introduction to EDGE wireless Internet access, and make a rough comparison with the appropriate user groups based on the characteristics of each method. Hope to help you.

What is EDGE?

EDGE is short for Enhanced Data Rate for GSM Evolution, that is, Enhanced Data Rate GSM Evolution technology. EDGE is a transitional technology from GSM to 3G. It mainly uses a new modulation method in the GSM system, that is, the most advanced multi-time slot operations and 8 PSK modulation technology. Because 8PSK can extend the signal space of the GMSK modulation technology used in the existing GSM network from 2 to 8, the information contained in each symbol is four times that of the original one.

There is a limit on the distance between wireless connection methods such as wireless routers. Generally, a good signal can be obtained only within a distance of about 100 meters in the room, and the speed of accessing the Internet is faster, in particular, after the publication of the IEEE802.11n standard, wireless Internet access products based on the new standard can enable the Internet speed theory to reach 300 Mbps, while wireless Internet access for mobile communication is basically not limited by distance, as long as you can achieve wireless Internet access in areas covered by China Unicom's mobile phone network, due to technical restrictions, the speed of wireless network adapter based on mobile GPRS is slow, it can only meet common Internet access or communication needs. China Unicom CDMA is better, but it is still limited by unsatisfactory speed, EDGE wireless Internet access, which was emerging in the past, can achieve an ideal effect. However, due to its recent development, the corresponding network is not perfect, and the cost is relatively high, there are also some restrictions.

Technically, GPRS cannot compete with CDMA in terms of speed, while CDMA cannot compete with EDGE in terms of speed. However, EDGE is subject to cost and coverage restrictions, EDGE wireless Internet access speed cannot compete with WLAN wireless Internet access, but WLAN wireless Internet access is limited by the density of wireless hotspot distribution. In general, they have their own advantages and no one can replace them. How should users choose?

What kind of audience is GPRS suitable?

GPRS wireless Internet access is a product of a mobile company. In the mobile phone market, mobile has a large number of users, and its GPRS network interfaces are also favored by many consumers, however, the speed cannot achieve an ideal effect.

In addition, wireless Internet access uses mobile phone networks. In terms of network deployment, mobile GSM network coverage is much wider than that of China Unicom CDMA, when using mobile phones, we can see that mobile phone signals are better than those of China Unicom in some remote mountainous areas. Based on these two reasons, GPRS wireless Internet access is more suitable for business users who do not have high requirements on network speed, but have high requirements on network signal and stability, it is mainly used for browsing web pages, timely communication, and sending emails.

Advantages: wide coverage, real-time online, convenient communication
Disadvantages: slow network speed and inconvenient to process large file transactions

What kind of audience is CDMA suitable?

CDMA wireless Internet access is a product of China Unicom (this article continues to follow the original statement due to the uncertain restructuring of China Telecom.

It belongs to a 2G network, and the GSM network belongs to the 2G standard. It has a faster speed than GPRS wireless Internet access, but in terms of network, due to various reasons, china Unicom's network is not fully covered yet, and the signal in some remote mountainous areas is not very good. As a result, wireless Internet access may be unstable in some mountainous areas. Based on the above analysis, we can see that the CDMA wireless Internet access method is more suitable for certain speed requirements, but it is not possible for some business people in remote mountainous areas to choose, you can do some small downloads, after work, you can play games that do not have high network requirements (after all, the speed of wireless Internet access needs to be improved, while some games require high network speeds ).

Advantages: real-time online and convenient communication
Disadvantages: weak coverage, Faster network speed than GPRS, and inconvenient to process large file transactions

What kind of groups is EDGE suitable?

EDGE wireless Internet access is a wireless Internet access product launched by mobile to compete with CDMA.

It belongs to a G wireless network, which is faster than CDMA and has a strong speed advantage. However, because it is still relatively young, the corresponding network coverage is relatively small, good performance in big cities. In addition, because it is a new product, it is more expensive than CDMA and GPRS in terms of Internet access fees. Therefore, EDGE wireless Internet access is more suitable for business users who often travel in major cities and have high requirements on network speeds.

After so many analyses, the final user should choose the wireless Internet access method based on their own conditions. Currently, each wireless Internet access method cannot be said to have an absolute advantage. It can only be said to have an advantage in one aspect. Therefore, when purchasing a product, you need to determine which applications you need to select to achieve the best results.

Advantages: GRPS and EDGE switching, real-time online, and convenient communication
Disadvantages: low coverage, Faster network speed than CDMA, and inconvenient to process large file transactions

What kind of audience is WLAN wireless?

A wlan is a derivative of a wired LAN. It is a means of accessing the Internet directly by using a wireless Nic in a small range of scenarios.

WLAN wireless network speed can reach up to 100 Mbps, but the coverage can only be around M.
 

Postscript:

The content of this article may be somewhat outdated, but here, I just want to introduce it to you. Each type of wireless network is excessive for the future. Currently, 3G is no exception. Now we have discussed more topics about 4G. However, in any case, this shows that our technology is constantly improving. Advanced technologies are also developed based on previous achievements.
