TWS and 5GHz spectrum data at your glance

ASIR is a WEB based platform for geolocated presentation of unused radio frequency spectrum throughout territory of the Republic of North Macedonia, focused around TWS - "Whitespaces" frequency range 470 to 790 MHz, and segments of 5 GHz frequency band, aiming to facilitate dynamic and effective utilization of the frequency resources.

Searchable Spectrum occupancy information for available frequencies and the status of interference relating to particular geo-location presented herein, is collected from fixed measurements executed on 59 locations and 84 drive tests made throughout the country. Spectrum scans made during the fixed measurements on the sites are made in all directions with 45 degrees offset thus indicating the general direction of the signals.
