Terrestrial broadcasting use of spectrum – does AIP have a role in promoting efficiency?

This report considered Ofcom’s proposals for the potential application of AIP to spectrum utilised for national terrestrial TV broadcasting. In its consultation on spectrum pricing for broadcasting, Ofcom stated that, where there are constraints on spectrum release, it does not expect “…the application of AIP to meet its core objective of securing the optimal use[…]

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[…]

Telemetry spectrum options

McLaren were interested in identifying alternative spectrum options to their current telemetry solution for F1 racing which would support significantly more monitoring etc. of the cars.  The study investigated and advised on potential availability of spectrum bands suitable for supporting mobile telemetry operations required at all the Grand Prix racing circuits.  A wide range of[…]

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[…]

Wireless home networking

The study addressed four key issues in relation to the use of UHF locally unused TV frequencies (commonly referred to as “white spaces”) for wireless home networking, namely: the current status of white space technology, availability of spectrum within the UK for white space wireless home networks, a comparison of the likely coverage in a[…]

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[…]

Wireless transmission of power

The study examined the state of art in wireless power transmission, transfer of electrical power, as seen from the perspective of the protection of radio communications services for Ofcom.  It considered the scientific background behind the different proposals, the technological developments, possibilities and limitations, and examined the consumer and economic aspects.  Particular attention was given to[…]

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[…]

IMT / TV co-existence across Africa

The study was required to review the potential availability of UHF TV spectrum (digital dividend) for mobile / BWA services across Africa (in particular in South Africa) and to assess interference between Electronic Communications Networks (ECNs) and TV broadcasting systems in the UHF band.  Guard-band / distance separation requirements were derived to bring interference between[…]

TV interference from Italy

The study involved an investigation into the potential for interference into mobile networks deployed in neighbouring countries, using IMT technologies, if Italy continued to use high power TV transmitters in the 790 – 862 MHz band for Digital Terrestrial TV.  The interference analysis was undertaken using the in-house spectrum planning tool and parameters from the[…]
