2、设计原则

本方案设计遵循技术先进、功能齐全、性能稳定、节约成本的原则。并综合考虑施工、维护及操作因素，并将为今后的发展、扩建、改造等因素留有扩充的余地。本系统设计内容是系统的、完整的、全面的；设计方案具有科学性、合理性、可操作性。

2.1 可靠性

无线网状网络不仅本身就具有高可靠性，而且还有高适应性。同时具有自愈的能力，并不需要网络管理员手动完成新路由设置。系统采用成熟的、稳定的、完善技术设备，系统具有一致性、升级能力，所有整个无线网络的拓扑设计、设备配置、协议支持都必须充分体现出对高可靠性的支持。无线网状网络不仅本身就具有高可靠性，而且还有高适应性。在系统故障或事故造成中断后，能确保数据的准确性、完整性和一致性，并具备迅速恢复的功能，同时系统具有一整套完成的系统管理策略，可以保证系统的运行安全。无线网状网具有自愈的能力，并不需要网络管理员手动完成新路由设置。

2.2 安全性

网络系统应具备多种可选安全机制，以适应不同应用情况下的需求；为那通信科技有限公司开发的WBEE、WCTU支持3DES、DES、AES等多种加密方式。保护用户的数据安全，防止数据被盗。

2.3 开放性

无线监控系统以现有成熟的产品为对象设计，同时还考虑到周边信息通信环境的现状和技术的发展趋势，可以与消防、防盗系统实现联动，具有RJ-45网络通讯口，可实现远程控制。

2.4 可扩充性

系统设计中考虑到今后技术的发展和使用的需要，具有更新、扩充和升级的可能，系统规模和功能易于扩充，系统配套软件具有升级能力。同时，本方案在设计中留有冗余，以满足今后的发展要求。

2.5 经济合理性

该系统具备只需一次性建设投入及后期相对低廉的维护费用的特点，而无需租用运营商光缆，只需办理流量卡业务，长期成本更加经济合理。同时网络设备及监控设备还可以根据实际需求在一定范围内进行迁移，保护投资； 站点数量设计采用覆盖和容量综合设计的方法，达到覆盖、容量、质量和投资成本的平衡，确保网络以最少的投资，满足用户的需求。
