WCDMA Introduction

I. WCDMA Introduction

WCDMA is a concrete developed by the 3GPP, GSM MAP based core

network, UTRAN (UMTS Terrestrial Radio Access Network) is a radio

interface of third generation mobile communication systems. Currently there

are WCDMA Release 99, Release 4, Release 5, Release 6 versions. WCDMA

full name is Wideband CDMA, Chinese translation for "Wideband Code

Division Multiple Access", WCDMA wireless broadband communications. It

supports data transfer rates ranging from 384Kbps to 7.2Mbps.

II. Demand Analysis

Examination Discipline is a prerequisite to ensure the smooth conduct of the

state's exam. Examination room has monitoring system, the use of information

technology to enhance the construction of Examination. It promotes the

examination discipline construction, improve the test management level, the

National Education Examination more fair and just.

Online Xunkao is a big step entrance examination, the examination will be

more fair and just. Online Xunkao increase the scope of the examination and

monitoring efforts strengthened monitoring. Online Xunkao the Xunkao staff

far beyond the traditional Xunkao in the examination room Xunkao member of

the network monitoring, provincial Shizhaoshengban, educational

administrative departments at all levels as well as government leaders can be

a test of Xunkao member. Xunkao online monitoring system, not only for the

candidates of the exam supervision, but also on-site supervision of invigilators.

In addition, online Xunkao timely, prompt reflection live on, will be conducive






to the recruitment sector trends accurately grasp the examination room,

capable of handling various contingencies good examination room.

Examination of 3G WCDMA wireless network video surveillance system not

only reflects the management level of the examination room, more conducive

to the examination of standardized management.

III. Investigation monitoring program

For our equipment, following are two solutions for customer reference

1. First Solution

A program by the camera, video server, Xiamen Caimore CM8150G WCDMA

wireless router and a central control room components:

A system consists of monitoring center, CM8150R WCDMA routers, video

servers and camera components:






Network topology: first

2. Second solution

Option II by the IP camera, Xiamen Caimore CM8150G wireless router and a

central control room components:






Network topology: first

1) video server or IP camera

Choose different brands of video server or IP camera according to the

environment and the needs of each examination.

2) wireless transmission using Xiamen Caimore of CM8150R 3G router

CM8150R wireless router, using high-performance 32-bit ARM9 industrial

communication processor for embedded real-time operating system software

support platform, the system integrates 3G wireless technology, online maintain

technology and VPN security technology, customers can

provide remote, stable reliable wireless video surveillance.

It can be widely used in mobile car video capture,

emergency command site video surveillance, traffic scene

video surveillance, passenger car safety video

surveillance, video surveillance field simulated combat






systems, financial security monitoring, engine room monitoring, industrial field

instrumentation monitoring and many other industries .

IV. networking implementation

System solutions in the WCDMA router is connected to the public

network-based monitoring center on the way to establish a VPN tunnel to transmit

video, network implementation as follows:

1) The monitoring center line mode access, can be with ADSL or fixed IP

address DDN, or Frame Relay FR.

2) CM8150R: Configuration open data services Unicom WCDMA 3G SIM

card, configure VPN (PPTP or L2TP) and other functional necessity, detailed

configuration, please refer to Xiamen Caimore "CM8150R WCDMA Route

Manual."

3) video server / IP camera: Configuring Video Server IP address and

Xiamen Caimore WCDMA router's IP address on the same network segment, IP

address, destination address of the gateway point to the WCDMA router is set to

a fixed IP address of the central control room, and other functional configuration

Please refer to the brand video server use.

4) The connection between the router and the operators of the monitoring

center, the best firewall, shielding off all unused ports, thus ensuring security

monitoring center.

5) System Check

After the current face four tasks are set up, you can click on the

corresponding node in the monitoring center camera into the real-time images:






The picture is as follows:

Enter the Configuration:






Remote configuration screen is as follows:






V. Conclusion

With increasing levels of production management, remote wireless video

surveillance has been widely used, more and more mature, and is moving

network, intelligent direction. WCDMA 3G wireless transmission of data using the

communication method to solve the communication problem of remote monitoring

system, compared to other wired communication has incomparable superiority.

Since the transmission of video image data, the amount of data and more

frequent, may choose not to limit the use of business packages more economical;

customers do not need a long time for monitoring can be used to activate

technology Xiamen Caimore router, when you need to see the image , it activates

the wireless transmission function, you do not need to watch, do not activate the

wireless transmission capabilities, so you can save communication costs. Our

laboratory constructed in the wireless remote video monitoring, access to the

desired results. Moreover, with the gradual improvement of mature WCDMA

network and application technology, WCDMA applications will be more broad.

WCDMA wireless transmission system presented here can be extended to a

variety of needs testing, monitoring and security of the environment.
