Standards for Wireless are based on the 802.11 and Bluetooth Standards  The IEEE 802.11wireless Ethernet standard defines methods by which devices can com­municate using spread-spectrum radio waves  Spread-spectrum broadcasts data in small, discrete chunks over the different frequencies (channels) available within a certain frequency range  802.11-based wireless technologies broadcast and receive on one of two license­ free industrial, scientific, and medical (ISM) radio bands: 2.4 GHz and 5.8 GHz
