Chapter II: Extender mode In extender mode, the Wi-Fi extender receives a wireless signal from a root wireless access point or router. It then repeats the signal it receives. This repeated signal can then be detected and used by other wireless devices, such as notebook computers, smartphones, and tablet computers. This extends wireless signal coverage and helps solve problems with wireless dead zones.

3-3 Glossary 1. What is the IEEE 802.11g standard? 802.11g is the new IEEE standard for high-speed wireless LAN communications, and provides for up to 54 Mbps data rates in the 2.4 GHz band. 802.11g is quickly becoming the next mainstream wireless LAN technology for home, office and public networks. 802.11g defines the use of the same OFDM modulation technique specified in IEEE 802.11a for the 5 GHz frequency band and applies it in the same 2.4 GHz frequency band as IEEE 802.11b. The 802.
a branch or SOHO operation. 5. What is Infrastructure? An integrated wireless and wireless and wired LAN is called an Infrastructure configuration. Infrastructure is applicable to enterprise scale for wireless access to central database, or wireless application for mobile workers. 6. What is BSS ID? A specific Ad-hoc LAN is called a Basic Service Set (BSS). Computers in a BSS must be configured with the same BSS ID. 7.
12. 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. Properly synchronized, the net effect is to maintain a single logical channel. To an unintended receiver, FHSS appears to be short-duration impulse noise. Direct-sequence spread-spectrum (DSSS) generates a redundant bit pattern for each bit to be transmitted.
