2.3 Ghz sharing analysis : a report from Plum Consulting

Abstract

This report for ComReg considers the compatibility and coexistence of new wireless broadband services provided by Mobile/Fixed Communications Networks (MFCN) and the existing Rurtel service, operated by Eir in the 2.3 GHz band, by examining the potential for interference from a co-channel and adjacent channel perspective. This report also investigates the impact of MFCN base stations operating in the 2.3 GHz band adjacent to Wireless Local Area Network (WLAN) devices operating in the 2.4 GHz band (2400 – 2483.5 MHz). The coexistence analysis presented in this report is based on deriving interference contours around RurTel receivers for an assumed set of receiver interference threshold values. The modelling assumptions are set out in Appendix A. Based on the analysis results, recommendations are made to ComReg to better inform its proposed Multi Band Spectrum Award and the need for additional technical licence conditions to facilitate the effective rollout of wireless broadband services in the 2.3 GHz band.
