Business does not happen just indoors—as wireless LAN (WLAN) devices proliferate, the need to provide them connectivity extends outdoors. Applications such as hot spots, outdoor surveillance, outdoor inventory control, or outdoor baggage handling all stretch the need for WLAN access. And it is not just providing access to client devices—remote networks need to be connected as well. These networks could be in remote buildings, or mobile networks that are located outside. These applications can be deployed cost-effectively with equipment designed specifically for these environments.
