Internet Engineering Task Force's (IETF's) Wi-Fi was supposed to reduce complications, not create new ones. Wi-Fi has been broadly adopted by consumers, and hot spots are in many public venues, including airports, hotels, and Starbucks coffee shops. In many offices, Wi-Fi does create problems. It is subject to interference, and its comparatively low power makes walls and cabinets barriers to signal strength. Wi-Fi also makes the network more open than wired networks, which causes security concerns. Also highlighted are the problems related to virtual private networks (VPNs), time spent trying to get connectivity in various locations while out of the office, and configuration and compatibility problems related to home connectivity as compared with software installed for access to the corporate network. Among companies working to assist with customers problems is Ruckus Wireless, which provides wireless access points with multiple antennas. Alan Cohen of Cisco systems says problems arise in offices because administrators are not used to the lack of transparency and control over the network, but the space continues to grow. Aruba Networks, AirTight Networks, and Air Defense provide new products that close security opening and ameliorate problems with signal strength.
