本方案设计覆盖包括医药物流仓库和办公室。 采用室内AP2942安装在仓库屋顶或者梁柱上，对仓库进行无线覆盖。室内AP7341针对办公室做高密度覆盖。室外AP7762-S覆盖仓库周围室外区域 考虑到仓库会有较多货物堆叠遮挡，无线扫描枪无线接收信号要求高等问题，不能有死角，因此设计AP用量较大。 无线系统采用目前市场上最先进的无线架构“瘦AP”，设计由一台控制器统一管理所有的AP，无论AP有多少数量，只要AP与控制器之间IP可达，就可以集中管理。所有AP均有网线连接到有线网内。 每个AP与POE交换机或POE模块相连，通过网线供电，无需布电力线。 AP可以灵活增减，根据实际需要进行部署，对于有盲点的区域，可以采用MESH功能增加AP覆盖，而不用布线。 本方案的AP可选用54M或300M，或混合使用。 ----------------------------------------------------------------------------------------------------------------------- Ruckus官方商城 无线论坛Ruckus优科教程专辑 需要更多详细教程请访问论坛Ruckus专版，论坛所发的教程贴子会不定期根据固件版本升级后修改对应教程。 1.Rukcus ZoneFlex AP快速设置手册 2.RUCKUS AP支架安装和拆卸说明 3.RUCKUS室内AP供电和连接教程 4.ZoneDirector控制器各版本支持AP列表 5.Ruckus胖AP无线路由器设置教程 6.Ruckus Unleashed虚拟控制器设置手册 7.Ruckus AP电子书包组播优化设置 8.Ruckus ZoneDirector无线控制器 9.x 设置手册 9.Ruckus ZoneDirector无线控制器 10.x 设置手册 关注本站微信公众号，订阅RUCKUS教程，更详细更全面的专业教程
