IEEE's 802.11, ultra-wideband (UWB), and ADI Engineering's Coyote are technologies that can assist designers in delivery of home devices that automatically interact to ease operation and share content. The devices have to work with legacy hardware and rival makers' devices, but also be sufficiently flexible to act with hundreds of products that have not yet been designed. One of the most common categories of equipment in digital homes is legacy entertainment devices, while the multifunctional abilities of desktops, laptops, personal digital assistants (PDAs), and some cell phones are also part of home networks. The many data storage and handling properties of today's platforms are highlighted. A LAN is required for flexible interoperability when many devices are used in the home, and the most basic computing network standard is EtherNet, which requires Category 5 wiring, a method that is preferred by many new homebuilders. However, Wi-Fi (802.11)-based wireless networking is also very popular with home network designers. Networks based on 802.11b can be easily penetrated without local security provisions, so 802.11a and 802.11g have been created. They are a much better choice for home networking. Another important element of the digital home architecture is the Internet connection, and most users choose high bandwidth connectivity based on digital subscriber line (DSL), cable, satellite, or wide area wireless methods. For instance, the Wi-Fi-Max 802.16a specification is a new non-line-of-sight, metropolitan area networking (MAN) standard that can transfer data at about 70Mbps over 30km to thousands of users from one base station.
