Data Rate Evolution
Facts of Cellular Phone Subscribers
2.14 billion in 2005; 2.7 billion in 2006. In several countries, including UK, there are more mobile phones than population. 80% of the world population enjoy the coverage of mobile phone service in 2008; this percentage increases to 90% in 2010.
Wireless LANs
Wireless Local Area Networks (LANs) support high speed data transmissions within a small region. All wireless LAN standards in the US operate in unlicensed frequency bands, such as 900MHz, 2.4GHz and 5.8GHz. IEEE 802.11 (WiFi) is the 2nd generation of LAN, which operates with 83.5MHz of spectrum in the 2.4GHz ISM band.
Other Wireless Communication Systems
Satellite communications. Digital wireless TV broadcast. Blue tooth. Cordless phone.
Wireless Spectrum
The frequency spectrum is divided into many bands.
