A. 1-100 mbps
B. 50-100 mbps
C. 1-20 mbps
D. 500 mbps to 1 gbps
Explanation: HIPER-LAN provides asynchronous user data rates of between 1 to 20 Mbps, as well as time bounded messaging of rates of 64 kbps to 2.048 Mbps. It uses 5.2 GHz and 17.1 GHz frequency bands.
A. Fhss and dsss
B. Thss and fhss
C. Thss and dsss
D. Hybrid technique
Explanation: Original IEEE 802.11 used both the approaches of FHSS (Frequency Hopping Spread Spectrum) and DSSS (Direct Sequence Spread Spectrum). But from late 2001s, only DSSS modems are used within IEEE 802.11.

B. Ieee 802.15.4
C. Ieee 802.11g
D. Ieee 802.11b
Explanation: IEEE 802.11b was a high rate standard approved in 1999. It provided new data rate capabilities of 11 Mbps, 5.5 Mbps in addition to the original 2 Mbps and 1 Mbps user rates of IEEE 802.11.
A. Hiper-LAN
B. Hiperlan/2
C. Ieee 802.11b
D. Amps
Explanation: AMPS is a standard of first generation network. HIPERLAN is a WLAN standard developed in Europe in mid 1990s. HIPERLAN/2 is also developed in Europe that provides upto 54 Mbps of user data.
