1. User mobility and or sotimes more cost efficiant 2. Physical cordial class (PHY), Medium Access Control (MAC), MAC focal point protocols and operate 3. A network in which the devices directly circulate with individually other 4. To relay the wireless signal and summation connectivity of a wider area 5. Direct Sequence expand Spectrum (DSSS), absolute oftenness Hopping Spread Spectrum (FHSS), Infrared, Orthogonal Frequency Division Multiplexing (OFDM) 6. implements 14 transmit (each consume 22 megacycle) over approximately 90 MHz of RF spectrum in the 2.4 GHz ISM (industrial, scientific, and medical) band.      North American DSSS conduct Channel Number          Frequency (GHz)      1                   2.412      2                   2.417      3                   2.422      4                   2.427      5                   2.432      6                   2.437      7                   2.442      8                   2.447      9                   2.452     10                   2.

Hopping Sequence - The rewrite of frequency changes. 9. 5 GHz, Orthogonal Frequency Division Multiplexing (OFDM) 10. a. 11 Mbps b. 54 Mbps c. 54 Mbps d. 200+ Mbps 11. Multiple Input Multiple produce (MIMO), MIMO uses a technique called space-division duplexing, where the info stream is split into multiple part called spatial streams. The different spatial streams are inherited victimisation separate antennas. With MIMO, doubling the spatial streams doubles the impressive data rate. 12. 802.11n only uses multiple data paths when faster data transmittal is requiredthus...If you want to get a extensive essay, order it on our website:
