* * * * Ethernet port on the PAP side has to be enabled by enabling Bridging ( security reasons) 若采用思科的无线网桥(100mW功率), 配合21dBi增益天线, 在2 Mbps下最远可达40公里(25英里); 11Mbps下可达18.5公里(11.5英里); * * Lightweight AP 相当于远程的RF接口; 主要提供相关的无线处理功能.而 无线控制器提供传统的无线流量处理, 安全处理,和射频控制与监控, 漫游, WLAN配置等等功能; 普通的Lightweight AP 用于室内部署；当控制器出现故障或者和控制器之间的连线中断时，就会停止工作。 HREAP （Hybrid-Remote Edge Access Point）用于部署在Remote Office这种场合。当广域网线路断掉时仍然可以继续工作。 1500采用无线互联的方式，为在城域范围部署无线提供了途径。 * 控制器版本Mesh Release 2或者以上 Supported Access points Cisco LAP1242AG-X-K9 Cisco LAP1131AG-X-K9 Supported Controllers Cisco 2100 Wireless LAN Controller Cisco 4400 Series Wireless LAN Controller Cisco Catalyst 6500 Series Wireless Services Module (WiSM) Indoors only 5Ghz Only for Back-haul 2.4GHz client radio is used on the RAP as well 4 MAPs supported per indoor RAP 3 hop network, Max 4 hops Omni antennas are used * * Unlike pockets of wireless LAN capability, a pervasive wireless LAN enables significant new capabilities. Guest, voice, security, and location services can all have a substantial impact on productivity, efficiency, and security when enabled organization-wide. Examplesof how pervasive wireless LANs can create new services, or renovate existing business processes to be more efficient include: ? Enhance decision making-Provide guest networks for customers, system integrators, and vendors to help speed information gathering and as part of the company hospitality. ? Track and secure assets-Reduce spending and personnel time locating or repurchasing assets through location services. ? Improve customer-facing services-Deliver instant access to customer account records, reach the closest available service associate, and track product progress in a manufacturing or repair facility. ? Improve logistics and maintenance-Update transportation management systems with passengers served, fuel status, collected revenues, and video surveillance logs as passengers enter the airport or station. ? Increase responsiveness and control
