Wireless connectivity Wi Max Broadband wireless access fixed
Wireless connectivity • Wi. Max – Broadband wireless access • fixed (home to Wi. Max base station) • mobile (mobile to Wi. Max base station and mobile to mobile). – – Alternative to last-mile cable and DSL access In practice, 12 Mb/s bandwidth with a range of 20 km Competitor to 4 G systems such as UMTS Complementary to Wi-Fi (typically 2 Mb/s bandwidth and 30 -50 m range) – Similar to Wi. Bro (Wireless Broadband), a Korean proprietary technology GL-e. Nestlé
Wireless connectivity • Bluetooth – Short-range radio communication protocol to transmit voice and data and to connect devices like PDAs, phones, laptops, PCs, headset, mouse, keyboards, game controllers, etc. • UWB (Ultra-Wideband) technology – Short-range high-speed connections to transmit video, audio and other high-bandwidth data between consumer electronic products GL-e. Nestlé
Wireless connectivity • Zig. Bee – Low data rates and low power consumption radio transmission technology to develop mesh network for industrial control, home automation, etc. • Insteon – Integrated mesh network combining wireless radio frequency with home existing electrical wiring to control appliances and to transmit data, voice, music, or video GL-e. Nestlé
Wireless connectivity • Mesh networking – Decentralized routing infrastructure where each node needs only to transmit as far as the next node – Very reliable and “self-healing": when a node breaks down or a connection goes bad, the networks tries to "hop" from node to node until a connection can be reestablished – Mesh networks can be wireless or fixed GL-e.
