1. Introduction As we all know, 3G network technology has three major technical systems, namely WCDMA, CDMA2000 and TD-CDMA technology. The first two technical systems because of the early, but also in Europe and the United States a number of well-known telecommunications equipment manufacturers, research institutions and operators support, so no matter from the standard or technical maturity, are relatively far ahead. TD-SCDMA is the

It is rumored that in the near future, 3G wireless networks will replace Wi-Fi wireless networks. Why is that? What is it based on? Please refer to the following for a good discussion on this topic. I hope you will have different opinions. Technical means: Although the wireless broadband technology is very suitable for a wide range of multimedia and enterprise applications, such applications are more used for laptops than mobile phones.

Do I still need WAP in the 3G era?(Article: Hero Wang) Recently, when chatting with friends, I often mention a topic. Do I still need WAP in the 3G era? This is a good topic. Most of the people who ask this question are WAP practitioners. What they are most worried about is that in the 3G era, when users use 3G to acc

PS: no navigation function is available after upgrade to baseband 06.15, Unless your iPhone baseband is already 05.14 or 05.15 and you need to upgrade it to 06.15, we recommend that you do not upgrade it for the time being. PreviousIt cannot be downgraded back to the old baseband. Now the new version can be downgraded back to the baseband, but some machines still cannot be downgraded, depending on your luck. My personal character is guaranteed, and the baseband is downgraded once. By the w

3G Network optimization has the same side with 2G network optimization, but also has its special aspects, so this paper mainly from 2G to analyze the 3G network optimization, mainly for reference to the 2G network optimization experience to the 3G wireless network optimization analysis. First, Introduction Because the mobile communication system is influenced b

The Most mature 3G network system is the WCDMA developed by the 3GPP project team. WCDMA network structure, can refer to Figure 12.1, which has several characteristics. 1. Reverse-compatible Gsm/grps network. The base station subsystem (BSS) of the original GSM network remains unchanged and can be interconnected with the transformed core network via the original a protocol stack and the GB protocol stack. 2. The core network maintains the netw

With the development of the routing industry, IPv6 routers are also widely used. So I have studied the practical application of IPv6 routers in the 3G mobile communication system. Here I will share with you, I hope it will be useful to you. Due to the rapid development of Internet and Internet applications in recent years, the number of people using networks and computers that are new to the Internet has rapidly increased. Currently, the 32-bit IPv4 a

Point of view 1: In the construction of 3G mobile transmission network, a simple idea is to build a set of independent ATM network for UTRAN, but ATM switching equipment is more expensive, and as a basic network, practice proves that it is not the best solution for other business. In addition, ATM has the problem of automatic configuration and recovery time of the whole network connection in the use of fiber network, and it can't meet the requirement

At the end of last year, the country's first 3G network was run in Guangzhou. During the same period, the media reported that 158, 159th will be classified as 3G resources. In Beijing, the 3G network has quietly covered two-ring main road. Users with a support for WCDMA and GSM mode of 3G dual-mode mobile phone, you ca

First, the experience of video call, after the temptation of high-speed Internet. Today, the three 3G technical standards will start completely. However, the parties on the 3G high-speed publicity despite the overwhelming, there is said that the test speed has reached 15Mbps, there are claims that the speed of 7.2Mbps, but the average consumer or "Mongolia check", 3G
