24、僅僅要求覆蓋范圍廣，信號(hào)強(qiáng)度大，上下行速率快，更需要低時(shí)延高可靠，低功耗大連接。在技術(shù)條件的允許下，無線城市的目標(biāo)是要把城市的每一個(gè)信息點(diǎn)連接起來，形成一個(gè)龐大的城市網(wǎng)絡(luò)。因此，組建城市無線網(wǎng)絡(luò)一定要控制好三大塊之間的聯(lián)系。1.11.1組成設(shè)備介紹組成設(shè)備介紹1.1.11.1.1無線控制器無線控制器無線控制器也就是無線局域網(wǎng)的訪問控制，它作為無線局域網(wǎng)的核心組成部分負(fù)責(zé)為用戶提供接入控制，統(tǒng)一管理，漫游等服務(wù)。由于城市的信息點(diǎn)不計(jì)其數(shù)，

25、因此無線控制器在分配的時(shí)候要遵循以下原則：1.確保范圍全覆蓋2.保證信號(hào)強(qiáng)度在可靠范圍內(nèi)3.要有冗余準(zhǔn)備。當(dāng)某個(gè)無線控制器出現(xiàn)故障時(shí)，能夠使網(wǎng)絡(luò)得到快速恢復(fù)。由于無線控制器是無線局域網(wǎng)的核心組成部分，因此在選擇型號(hào)時(shí)一定要支持IEEE802.1n和最新的WAPA2PSK加密方式。1.1.21.1.2無線接入點(diǎn)無線接入點(diǎn)無線接入點(diǎn)是無線局域網(wǎng)的接收器。無線終端通過接入點(diǎn)才能進(jìn)入局域網(wǎng)，從而訪問其他資源。主要有路由交換接入一體設(shè)備和純接入點(diǎn)
