Continued use of 2.6 GHz for broadcasting versus allocation for mobile broadband in Ireland

Aegis and Plum supported ComReg in analysing the costs and benefits of continued use of 2.6 GHz spectrum for broadcasting versus possible release for mobile broadband.  The Aegis-Plum response to submissions was published by ComReg in December 2012, and is available here. The Aegis-Plum response concluded that that the benefits of early release of 2.6[…]

Survey of cognitive radio developments

The study undertaken with consulting firm RTT reviewed the standardisation activities for cognitive radio.  The activities of ETSI, IEEE, IETF and ECMA were examined in detail.  As part of the study the key barriers and enablers of the adoption of cognitive radio were identified as shown in the figure below. The study also explored various[…]

Co-existence between LTE and Analogue TV

The study examined the potential for a 10 MHz FDD LTE network roll-out in major population centres in South Africa in the Region 1 digital dividend band (i.e. 790 – 862 MHz).  It reviewed analogue TV use in South Africa, established representative modelling parameters, developed appropriate sharing criteria and interference analysis methods and examined the[…]

Options for Region 1 2nd Digital Dividend Band

This study considered the band plan options for the 698 – 790 MHz spectrum (2nd digital dividend band) following from the decision at WRC-07 to identify the band 698 – 806 MHz for future IMT systems in Regions 2 and 3.  The intention was to explore the band plan options to similarly extend the digital[…]

Public safety spectrum requirements

The study addressed the likely spectrum requirements for public safety (PPDR) spectrum requirements in Europe for the German Federal Ministry of Economics and Technology.   The functional requirements of European government agencies with PPDR responsibilities were reviewed by conducting extensive stakeholder interviews.  Quantitative modelling was then performed to translate and further refine these requirements  into detailed[…]

Interference analysis from ECN into Cable TV

The interference analysis between base stations (BSs) of ECN (electronic communication networks) was undertaken based on the assessment of a single interference path into the victim cable TV network elements. In the analysis, the distance between the interfering BS and the victim was increased in regular steps.  At each distance, the implications of mean path loss[…]

DTT briefing note

The purpose of the study was to develop a briefing note that covered the issues concerning the amount of radio spectrum required by terrestrial television services once they have migrated from analogue to digital transmission. The note explores the different digital TV technologies used around the world (PAL, ISDB, ATSC).  It also considers the other technical issues,[…]

Backhaul for rural broadband services

The feasibility of deploying adaptive fixed links in the 1800 MHz band to provide backhaul links in rural areas for the UK was examined for this study.  Issues considered included regulatory constraints, cost savings, equipment development, bandwidth requirements, achievable link lengths, in-band interference, cross border coordination and harmonisation opportunities. An example scenario was considered where[…]

Licence conditions variation support

UKBB were seeking support for a variation to their technical licence conditions.  They were seeking a relaxation of the base station and terminal block edge masks in ther licence from Ofcom to provide more flexibility regarding equipment.  The study undertook modelling of interference potential from base stations and terminals under various  block edge mask scenarios to[…]
