Abstract: The present invention relates to a method and apparatus of radio link selection based on delay spread, the user equipment according to the present invention receives radio signals from neighboring multiple base stations, measures delay spread of the signals received from the multiple neighboring base stations, selects at least one base station among the neighboring base stations based on the delay spread measured, and connects a radio link with the selected at least one base station. According to the present invention, the inter-symbol interference due to delay spread can be decreased, thereby it is available to implement the maximum transmission speed in a given propagation environment.

Abstract: Provided is a method for automatically measuring propagation characteristics of millimeter radio waves and acquiring data using a simple network management protocol (SNMP) in real time. A remote server may control a transmitter control terminal and a receiver control terminal, which control a transmitter and receiver separated from each other at a predetermined distance so as to measure propagation characteristics, through a wired/wireless network using the SNMP.
