HIPERLAN/1 vs HIPERLAN/2: Key Differences Explained

This article compares HIPERLAN/1 and HIPERLAN/2, highlighting the key differences between them. HIPERLAN, short for High Performance Radio LAN, is a European counterpart to the IEEE 802.11 standards, developed by ETSI BRAN.

HIPERLAN/1 Features

Here’s a rundown of what HIPERLAN/1 offers:

• Frequency: Operates in the 5 GHz band.
• Data Rate: Supports data rates up to 19 Mbps.
• Modulation: Employs Single Carrier (SC) modulation, such as GMSK.
• Equalization: Uses a complex equalizer to manage delay spread.

HIPERLAN/2 Features

Let’s explore the features of HIPERLAN/2:

• Frequency: Operates at 5 GHz with a 455 MHz bandwidth.
• Data Rate: Supports data rates from 6 Mbps to 54 Mbps, similar to 802.11a.
• Modulation: Uses multi-carrier modulation (OFDM), akin to 802.11a.
• Power: Utilizes two bands: one for indoor use (200 milliWatt power) and another for outdoor use (1 Watt power).
