【正文】 wn. China has always adopted a positive and moderate attitude of 3G that China currently conducting the second phase of the work technology test or the outfield test. The tests included : 3G coverage, capacity and other performance test。 Between different 3G technology, technical interference between 2G and 3G, coexistence。 the main market is still in the stage of enlightenment. The killer also did not show business。s munications technology standards, there is the issue closed. This is also a major reason for the attack by the international 14 munity. The new darling of WIMAX Broadband Wireless Technology Show that WIMAX has bee the largest telemunications recent Inter search word. The technical characteristics of its much coverage and high bandwidth, the wireless industry have bee a new favorite. WIMAX39。s concern, it is UWB. UWB is a timedomain munication technology, using ultrashort pulse modulation. 0 or 1 according to the signal sent out directly, without using the carrier, which is very different from previous wireless munications. Ultrawideband signal to the pulse modulation signal spectral density low. 650MHz~5GHz center frequency in the signal between mw average power at the order, and the ability to multipath interference, and has a number of available channels. With the CDMA system, the timedomain munication system is simple, relatively low cost. UWB technology with high speed, low cost, low power dissipation characteristics significantly. 3 The trend grasp: Access multiple works and Represent a prehensive layout direction More on the current hot field of wireless munications and focus the issues described and discussed. So, are we going to grasp the development trend of the midWireless Future? First, the field of wireless munications technologies plements each other more and more clearcut. This was reflected in the different access technologies with different coverage, the application of different regions, different technical characteristics, solve the access speed 3G mobile WAN seamless roaming coverage, and strong demand. WLAN solve the distance over which highspeed data access, and proximity to achieve ultra highspeed UWB wireless access. Therefore, in a policy, we should promote the integrated development of various wireless accesses, a work promoting the integration process, diversification of the 15 means of access through the work to achieve coverage of the needs of different user groups. Achieve market segmentation and business diversification, the development of mobile munications to resolve the situation is not balanced. Secondly, the government should give more enterprise wireless frequency distribution of resources promoting different technology in the planning and application of frequency spectrum. This will be conducive to the development of enterprises of different strategies and different market needs, Comprehensive planning its own wireless munications work, the effective allocation and use of resources. Third, the public mobile munication work development, China has bee a global 3G mobile works evolution of the process. From the experience of developed countries in Europe and the United States, because of its high peration rate of mobile voice users. Users achieve growth through the development of the model has bee a part of history. Therefore, they expect to build greater operational 3G platform, a new source of profit. Due to the maturity of 3G technology, the deployment of 3G mercial works has started on a global scale. For our part, and learn from the experience of Europe and the United States, slow growth in the number of users, it should be brought forward in fostering the development of new mobile market. Fourth, broadband wireless access technology, the world is very exciting development in the field. Developments in the field have shown a high bandwidth, rapid progress, and gradually expand the coverage of the trend. Future in the field of new technologies may emerge stronger from another angle to play a role in the entire wireless munications industry. But recently, the development of broadband wireless access technology should have a rational attitude and scientific grasp. The current fixed broadband wireless access technology environment focused on the highspeed access. Its ability to support mobile voice and mobile munication works and the public can not resist. Fifth, what should be the future of wireless munication works? Experts believe that the future of wireless munications work will be a prehensive integration solution. From largescale public mobile munications, 3G or super 3G technology will be dominant。 and WLAN, WIMAX, UWB and other broadband access technologies will be different because of their technical characteristics, coverage or application in different areas, to create an effective and plementary public mobile munication work. 4 Conclusions As wireless mobile munications work bandwidth demand and lack of work bandwidth. users demand imbalance in the geographical distribution and the use of different technical strengths and weaknesses and contradictions in the coexistence of contradictions, it determined that the need for the development of the wireless munication work using various technical means, from the overall and longterm perspective, integrated planning and the idea to build a work. Play different technical character, prehensive layout, and different regions, different groups of users and business demands for bandwidth, Wireless munications work to reach the overall advantages and prehensive ability. In this regard, my government departments should also actively spectrum for the operators with adequate resources。s neighborhood is authorized, without increasing the port, but also able to share the inter. 2 WIFI development in the future These two y
