Basics of HIPERLAN/1 vs HIPERLAN/2
This page compares HIPERLAN/1 vs HIPERLAN/2 and mentions difference between HIPERLAN/1 and HIPERLAN/2.
HIPERLAN is the short form of High Performance Radio LAN. It is variant of IEEE 802.11 standard developed by ETSI BRAN for use in European region.
Following are the features of HIPERLAN/1:
• Operates at 5GHz
• Supports data rate upto 19 Mbps.
• It uses SC (Single Carrier) modulation such as GMSK.
• It uses complex equalizer to take care of delay spread.
Following are the features of HIPERLAN/2:
• Operates at 5GHz with 455MHz bandwidth.
• Supports data rate of 6 Mbps to 54 Mbps similar to 802.11a
• it uses multi carrier (i.e. OFDM) modulation like 802.11a
• It uses two bands one for indoor use and the other for outdoor use with power
at 200 milliWatt and 1 Watt respectively.
