1 Current 3G situation and important issues that people focus on
People's focus on 3G has gone through two different stages. 2001-2002, people's energy is mainly focused on mastering 3G basic technology, through indoor testing and field debugging and other means of technical validation; 2003-2004, while continuing to verify the
This paper first analyzes the importance of 3G indoor coverage from the operator's point of view, and then according to the planning principle of 3G indoor coverage, considering the selection of signal source and distribution system, finally briefly introduces the construction flow of 3G indoor cover.
With the 3G pace
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
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,

What is the difference between Apple iPad and ipad2 in 3G and WiFi? I believe this is a concern of many friends! You will understand the following 20 questions!
1. What is the difference between Apple ipad2 3G edition and WiFi edition?
In terms of appearance, the top and back of the 3G version of ipad2 have a Black edge and a card slot, and the weight is 40 grams
At present, China's 3G experiments and outfield testing is actively underway, the industry on the construction of 3G mobile network is very enthusiastic. For various reasons, the Ministry of Information industry is very cautious about the business of 3G service and has not yet made clear the time of issuance of 3G lice
December 24, 2003, one of the world's top 500 of the United Arab Emirates Telecom (Emirates Telecommunications Corporation, referred to as Etisalat) officially announced that The WCDMA network from China's Huawei Technology Co., Ltd. was formally put into commercial application, and Huawei, as its exclusive supplier, contracted the National WCDMA Commercial network of the UAE telecom. The cooperation between the two sides will make the UAE telecom become the first in the Middle East and the Arab
Although, at present, 3G wireless communication networks have not been applied to every mobile user as expected. However, the author believes that this is only a matter of time, and does not prevent us from looking forward to the bright future of 3G wireless communication networks. 3G has set a new goal for itself-digital intelligence for our lives.

Zte cs competition pushes 3G Marketing
This is China's first 3G year. Many manufacturers have invested a lot of money and technology to win 3G profits. As China Telecom took over the CDMA network, mobile TD-SCDMA coverage and the formal commercial use of China Unicom WCDMA, 3G in most major cities daily use has al
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
3G era brings more challengesThe arrival of the 3G era poses a huge challenge to operators, such as immature technology, limited funds, and uncertainty in market demand. In addition, operators must also provide high-quality and inexpensive 3G services, while ensuring network scalability and reducing network investment and operation costs. Due to the uncertainty o
In recent years, SoftSwitch technology has become the focus of public attention, it will become the core technology of the next Generation network, the information industry after a turn to put forward to the next generation of IP Fusion network SoftSwitch technology, is currently active in 3G core network technology research, the ultimate goal is to have the integration of multimedia business capabilities of the full IP network.
In this regard, 3GPP
Interoperability testing (IOT) is the technical basis for the formation of multiple vendor operating environments. Only through the interoperability testing of IU interface can the interconnection between wireless access network and core network of different manufacturers be ensured, and only the interoperability test of UU interface can be done to ensure interconnection between each mobile phone and wireless access system.
