Assessing the proposed merger between Sky NZ and Vodafone NZ

In 2016, Vodafone New Zealand and Sky Network Television Limited proposed to merge their businesses, and applied to the New Zealand Commerce Commission (NZCC) for clearance. Under the New Zealand Commerce Act 1986, the NZCC can grant clearance if it is satisfied that the Proposed Transaction will not have the effect or likely effect of[…]

700 MHz modelling

We undertook a number of modelling studies for Ofcom in 2014-2015, to inform their policy on technical conditions relating to the release of 700 MHz broadcast spectrum for mobile use.  The most likely band-plan involved the user equipment (UE) handsets transmitting at frequencies immediately above the remaining broadcast allocation, with base stations assigned spectrum higher[…]

Measuring interference to DTT at 800 MHz

We have provided specialist technical advice to ‘Digital Mobile Spectrum Limited’, the UK body charged with managing issues of LTE to DTT interference at 800 MHz LTE. This work has involved a number of strands including;  the development of algorithms and computer models for the site-specific prediction of interference from mobile base stations to domestic DTT receivers;[…]

Terrestrial broadcasting and spectrum use in the Arab states

In order to identify where spectrum in the UHF bands could be made available for mobile broadband, Plum surveyed the television broadcasting markets across the Middle East and calculated how a move to digital television could free up significant amounts of spectrum in the sub-800MHz bands.  Starting with the assumption that the number of channels[…]

Regulating for effective competition in Mexican telecommunications

Plum carried out a major study for the board of the IFT – the telecommunications and broadcasting regulator – in Mexico. In March 2014 the newly formed IFT declared AMX a preponderant economic agent in the telecommunications sector and Televisa a preponderant economic agent in the broadcasting sector, with a review of market conditions after[…]

The estimated cost of capital for broadcast transmission, 2015-2025

Plum estimated the weighted average cost of capital (WACC) for broadcast transmission services on a ten year forward looking basis for the Office of the Adjudicator Broadcast Transmission Services.  The assessment took into account differences between broadcast transmission and other regulated industries including the existence of long-term contracts and future risks to broadcast transmission due[…]

Challenges and opportunities of broadcast-broadband convergence and its impact on spectrum and network use

Plum led a 12 month study, working with Farncombe, to assess the options for future use of UHF spectrum in the EU – with a focus on the case for and against a converged mobile/DTT platform. The study involved: Wide consultation with, and three workshops for, industry players A detailed assessment of how audio-visual services[…]

What next for DTT? The case for implementing T2 at the same time as 700MHz clearance

Plum assessed the social and economic impact of adoption of a more efficient transmission technology (i.e. DVB-T2) on digital terrestrial television (DTT) at the time of 700MHz clearance (assumed to be 2019-2021). If the 700 MHz band (694-790 MHz) is repurposed from broadcasting to mobile use, the spectrum available to broadcast TV would be reduced[…]

Benefits of digital broadcasting

Plum and Farncombe developed for the GSMA a summary of the benefits of digital broadcasting that flow to players on the broadcast value chain.  The benefits for the broadcasting industry of the transition to DTT include: An increase in the capacity of broadcast transmission networks by improving spectrum efficiency (i.e. more data can be transmitted per[…]
