Every wireless Local Area Network (LAN) deployment is different. When engineering an in-building solution, varying facility sizes, construction materials, & interior divisions raise a host of transmission & multipath considerations. When implementing a building-to-building solution, distance, physical obstructions between facilities, & number of transmission points must be taken into account. Cisco is committed to providing not only the best access points, client adapters, & bridges in the industry-it is also committed to providing a complete solution for any wireless LAN deployment. That's why Cisco has the widest range of antennas, cable, & accessories available from any wireless manufacturer. Cisco offers an Antenna Kit with 5.2 dbi Omni Ceiling Mount Antenna & 3-feet cable. Please note: networking components such as switches, routers, UPS & wireless devices require that speeds & standards be consistent throughout the network to gain optimum performance.
