With the development of mobile communication in China, the construction of the third generation mobile communication network has become the focus of major telecom operators.
The third generation mobile communication technology test network of the Ministry of Information industry is led by the Ministry of Information industry to participate in the formation of the major telecommunications operators, the test network in the 2GHz band, respectively, WCDMA R99, TD-SCDMA, CDMA2000 1X Three kinds of
With the emergence of a large number of Wi-Fi hotspots and micro-cell base stations, the era of a single large base station tower may end at this year's World Mobile Communication Conference. This year's World Mobile Communication Conference will show a variety of small base stations and Wi-Fi integrated systems.
Ip. access is one of the Infrastructure vendors in this field. The company is the manufacturer of ATT MicroCell consumer micro-cell base stations. The UK-based company announced its R
I. BACKGROUND
Because of the current commercial situation in Japan and the 3G test conducted in Europe did not achieve the expected results, 3g-foma operators 3G plans are further postponed , the company has also been WLAN (Wireless LAN) and 2.5G GPRS integration on the agenda, in order to strengthen the broadband and applicability of wireless Internet access, t
Based on the needs of network convergence, from a technical perspective, 3G/PHS network convergence is feasible.
Background of PHS and 3G network convergence
As an important source of income for fixed-line Chinese telecom operators, PHS has contributed and contributed to fixed-line telecom operators. How to combine Problems in the Development of the PHS network, expand the PHS network business in depth, con
HSDPA) Mobile phones support 3G (WCDMA) and 2G (EDGE, GPRS and GSM) technologies. There are also other mobile phones supporting 3G cellular technology such as the CDMA 2000 1x EV-DO and TD-SCDMA, which also consume a lot of power.
Whether it is 3G or 2G, the power amplifier consumes a lot of power, so an effective method is required to get a longer call/working
Introduction
The author was fortunate to participate in the overall project design of the third generation mobile communication technology test network of the Ministry of Information Industry and the design work of the Beijing Area Test Network project. 3G test Network adopts WCDMA R99, CDMA2000 1X, TD-SCDMA three kinds of technology construction. When considering the 3g scheme, we combine the characterist
Each wireless technology has its own advantages and disadvantages. Various kinds of publicity are also emerging. Therefore, this article only compares the wireless WINMAX technology with other wireless technologies, so this article mainly compares with the 3G wireless technology.
WiMAX to 3G
3G is an ITU specification that supports high-speed wireless communicati
China's 3G Network has now officially entered the commercial stage, many users hope that 3G network can be wired broadband, so that the realization of multiple computer sharing Internet. 3G wireless routers have emerged in this type of customer demand. In the specific use of 3G wireless router,
Although 3G is an integral part of NGN, its development is also more or less affected by the Softswitch technology. From this, we can see that the Softswitch technology has become the focus of public attention in recent years, it will become the core technology of the Next Generation Network. The information industry has made great efforts to propose the Softswitch technology for the Next Generation IP converged network. At present, it is actively con
After analyzing the structure of the softswitch network, this article describes the hierarchical structure of the UMTS Release5 network, which reflects the application of the softswitch concept in 3G. Combined with the wireless LAN mode, 3G and WLAN Integration solutions are discussed.
In recent years, the Softswitch technology has become the focus of public attention and will become the core technology of
