Planning And Design For UMTS900 Wireless Network

With the rapid development WCDMA2100 network, China Unicom 3G network constructions in the rhythm of the city has been easing, the next focus is mainly in the suburbs and rural areas to enhance the 3G network coverage of the breadth and depth. The suburban and rural terrain of H city is vast, sparsely populated, and severe terrain blocking, where large impact on 2100 MHz frequency signal propagation, using WCDMA2100 to deploy 3G networks, huge investment and operation of the network is not ideal. Therefore, the application of other 3G network operators to build network model is becoming a direction.In this paper, to solve the increase 3G network coverage breadth and depth in the suburban and rural terrain of H city. Specific uses a low frequency of 900MHz(UMTS900) 3G network standard to deploy, by planning a series of design principles UMTS900 network of different scenarios, different scenarios using different methods and design principles for UMTS900 deployment network planning, to meet the demand for 3G networks in suburbs and rural areas,. The main contents include the following aspects:1. The characteristics and key technologies UMTS900 technology is introduced in detail, comparing the differences in a variety of formats WCDMA2100 business communication, visual demonstration of the UMTS900 technical superiority is demonstrated in the case of H City illustrate the feasibility of its deployment.2. The design for wireless network planning process, planning methods and principles for a detailed description. Specific network design and planning of the detailed design is based on the design process and planning methodologies and guidance.3. Analysis the unique business needs of the suburban and rural of H city, customer complaints, weak coverage areas, and the amount of funds, the use of wireless network planning and design methodology proposed optimal networking solutions and goals.4. UMTS900 and GSM900 joint research networking. Because both UMTS900 and GSM900 for networking within the band within 900 M, so the network is performing particular attention to the impact of the current GSM network can be deployed in determining the peripheral regions and UMTS900 to set up a buffer to avoid a greater mutual interference.5. Base station planning and design in two scenarios(highway&scenic). UMTS900’s base station mainly through pre-business requirements, user requirements and network-related data etc, analysis of these raw data into the link budget equation, get relevant propagation model. Analysis of these raw data through the link budget calculations and propagation model formula. To give coverage of base stations, to determine the number of base stations, and mainly due to UMTS900 network construct with G900, the places of UMTS900 base station are ofter same, we are main consideration station configurations.
