DAS VENDORS UNDERSTAND WI-FI AND ARE MOTIVATED

摘要

This solves the coverage concern, but if more capacity than what three APs can offer is required, segments must be subdivided. LGC Wireless has an active DAS that it sells primarily through carriers, but it doesn't tie a WLAN product inside its DAS. Instead, it offers RF engineering, consulting and installation services, working closely with Cisco. Another vendor, MobileAccess Networks, offers systems across both active and hybrid categories. In its architecture, a central closet aggregates cellular, PCS and paging signals, and transports traffic over fiber to each floor's IDF (intermediary distribution frame) or telecom closet, where Wi-Fi is added. At that point, signal is taken off fiber and shuttled onto RF. Discrete broadband antennas radiate the signal, rather than leaky coax. This vendor has a tighter relationship with Cisco than most-its MA-850 WLAN Module has been officially tested and listed as compatible with Cisco's Unified Wireless LAN.
