4.4.1 Technical presentation of the project4.4.1 项目技术介绍
?? Technical presentation?? 技术介绍
The project is essentially based on CDMA technology (Code Division Multiple Access).项目本质上是基于 CDMA技术(码分复用接入). The CDMA technology (Code Division Multiple Access – Accès multiple par codage individuel) is the process used during the radio connection between UMTS mobiles and local antennas. CDMA技术(码分复用接入– Accès multiple par codage individuel)是使用在UMTS可移动和本地天线之间的无线连接上的一种方法. It allows the coding of communications in order for each mobile phone to receive the communication intended for him.它允许每台移动电话以有序的编码的形式收到特定的通信 This project is essentially based on one variation of the CDMA, which is 2000 1x, a technology intended for IMT-2000 (3G) mobile phones, which allows debits of data commutation transmission per packages reaching sometimes 144 kbit/s. CDMA allows the transmission of the voice, data, textes and images.这个项目是基于CDMA的一个变种2000 1x,一个为IMT-2000 (3G)移动电话设计的技术, 它允许数据交换传输的借入,有时速度可达144 kbit/s. CDMA 支持语音,数据,文本和图像的传输.
The project is therefore a wireless telephony network using another norm than GSM.因此,该项目是一个无线电话网络,使用的是GSM之外的标准. CDMA appears like an alternative to GSM, which is more expensive to display.CDMA看上去像是GSM的另一个方法,但GSM操作更贵.
With its technical root integrated to Internet protocol, CDMA is providing an easy way to internet.由于它的技术根源在于因特网协议,CDMA更容易的接入因特网. With such quality, the project is able to provide an Internet connection via the same channel.在这样的质量下,项目能够用同一条信道提供因特网连接.
?? Presentation of the product and service supply?? 产品和提供服务的介绍
The offer of the technical partner is based on the CDMA 450 standard, a variation of the mobile CDMA 2000 technology.技术合作方的提议是基于CDMA 450标准的,它是CDMA 2000技术的一个变体 As an international 3G standard (Third Generation), the CDMA 2000 solution presents a large capacity, a larger coverage, of high debit service of data in batch mode, of distinguished service and a flexible development; all those functions make it be the most appreciated Wireless Local Loop Technology (WLL) which would allow to give a better coverage of non reached areas of an existing network.作为一项3G(第三代)国际标准,CDMA 2000代表了更大的容量,更大的覆盖面,更高的数据批处理模式的服务,高级的服务和灵活的发展,所有这些功能使得它作为最合适的无线本地环路(WLL)来覆盖那些现有网络不能到达的地区.
The CDMA WLL technology is a well elaborated solution technically mature, which may provide both services of voice and data to the final client.CDMA WLL技术是一个技术成熟,精心设计的解决方法,能够提供给最终客户语音和数据的服务. Solutions using copper being more often very expensive and too long to display, the BLR system appears like an economically fit technology to provide telecommunication services to subscribers of less peopled areas as well as those largely occupied.使用铜线的解决方法更昂贵,实现时间也更长,BLR系统是一种更经济的技术,能够将电信服务提供给人烟稀少的地方,如同那些人口众多的地方 Therefore, for a more rapid increase and a cheaper cost of teledensity, BLR technology is more appropriate than solutions based on the traditional copper cable.因此,为了使得电话密度以更低成本更快的增长,BLR技术比传统的基于铜线电缆的技术更为合适.

- Interoperability- 协同工作能力
In perfect harmony with standardization, the CDMA system is provided with an excellent interoperability, which is the essence of the existing economy, and strengthens the performance of the network through the integration of the latest technologies from the same or diverse suppliers.与标准化完美融合的CDMA系统具有良好的协同工作能力, 协同工作能力是现有经济的核心,并且通过综合来自同一个和不同供应者之间的技术加强了网络的表现<0}
High stability and reliability高稳定性和可靠性
The CDMA standard uses advanced technologies to strengthen the stability and the reliability of the system such as the immediate and automatic switching with a distributed architecture, the configuration of the tolerance to breakdowns, the mechanism of load-sharing, the mechanism of complete redundancy of multiple nodes, and the multiple mechanisms of backup, assure the performance of the system to be continuous.CDMA标准使用了先进的技术来加强系统的稳定性和可靠性,如分布式建筑的直接和自动的交换,抗死机的构造,负载分配机制,多节点完全冗余机制,以及多备份机制,保证了系统持续的良好表现.
- High radio performance- 高无线通信表现
The performance of the radio network is the key for the state of art of the CDMA system.无线网络的表现是CDMA系统技术状态的关键. This technology has a very large network radio capacity.这种技术有一个很大的网络无线容量. As a matter of fact, the very efficient algorithm of allocation of radio resources, allows a complete exploitation of the radio resource to a large extent.事实上,这种无线资源分配的很有效的算法在很大程度上充分开发了无线资源
- Adaptable evolution and flexible extension- 可修改的进展和灵活的扩展
The leveling of the CDMA system in order to provide value added services of networks of third, let’s say fourth generation, is very flexible; because this technology bears modular configurations thus allowing an easy extension and up dating.CDMA系统的分级是为了提供第三代网络的增值业务,我们可以称为第四代.因为这种技术的模型构造使得扩展和升级更为方便. It also provides the possibility to realize a soft switch.它也提供了实现软交换的可能性.
The current CDMA network of Togo Telecom is a 450M network based on a NGN – CDMA WLL structure.现在多哥电信的CDMA网络是一个基于NGN – CDMA WLL结构的450M的网络,. The project aims at having the system imigrate towards a 800M network.项目的目标是使系统发展为800M的网络. The project will allow:项目将允许:
- to extend the current network,- 扩展现有网络,
- to protect the existing equipments and- 保护已有设备
- to guarantee an adequate implementation.- 保证适当的执行.
