Can I play computer games with other members of the wireless network The game must support multiple players over a LAN local area network What is IEEE 802 11 standard The IEEE 802 11 WLAN standards subcommittee is developing this standard for the industry The objective is to enable WLAN hardware from different manufacturers to communicate The 802 11 and 802 11b specifications apply to wireless Ethernet LANs and operate at frequencies in the 2 4 GHz region of the radio spectrum What IEEE 802 11 features are supported The product supports the following IEEE 802 11 functions CSMA CA plus Acknowledge protocol e Automatic Rate Selection e Multi Channel Roaming Power Management e RTS CTS feature Fragmentation Can Wireless products support printer sharing Wireless products perform the same function as LAN products Therefore Wireless products can work with Windows NT 2000 or other LAN operating systems to support printer or file sharing What is DSSS What is FHSS And what are their differences Frequency Hopping Spread Spectrum FHSS uses a narrowband carrier that changes frequency in a pattern that is known to both transmitter and receiver but not an unintended receiver Direct Sequence Spread Spectrum DSSS generates a redundant bit pattern for each bit to be transmitted Even if one or more bits in the chip are damaged during transmission statistical techniques embedded in the radio can recover the original dat2.
