The study conducted for the EC, DG CONNECT, considered the possible impacts of off-loading from macro-cellular networks using Wi-Fi, femtocells, and/or picocells. It assessed the potential socio-economic benefits of traffic off-load in achieving DAE (Digital Agenda for Europe) goals, and the amount of spectrum that will be needed to achieve those benefits. The study considered[…]
Undertook a number of interference studies to examine the potential of releasing the 1.4 GHz band for mobile as part of the preparations for WRC-15. This included development of co-channel and adjacent band interference scenarios to examine the impact of IMT emissions on radar receivers operating in 1300-1400 MHz band; investigation into the potential for co-channel[…]
The study undertaken with the consulting firm RTT reviewed the evolution of global cellular frequency bands and multi-band handset support and considered the design challenges associated with supporting new frequency bands and the associated costs and benefits of such support. The likely relationship between the number of frequency bands supported and the RF cost and[…]
In March and December 2012 OFCA published consultations on the arrangements to award spectrum in the 1.9 to 2.2 GHz band (2.1 GHz spectrum) when licences for existing assignments expire in October 2016. Plum was commissioned to assess the nature and scale of disruption including the cost impacts of OFCA’s proposal.
Plum prepared a report on the European app economy and proposed policy measures to support the growth of the app economy for the Association for Competitive Technology (ACT). Plum supported ACT in presenting the report at events in Brussels, Paris and London to policy makers and politicians.
Plum prepared a report for Qualcomm that appraised the economic and social benefits of releasing 2.1GHz spectrum for 3G services in Pakistan. The report quantifies the economic benefits, in terms of a GDP impact and revenues raised from the auction of spectrum, and discusses the considerable social benefits from use of 3G services to enhance[…]
Plum provided an opinion on the ACM’s December 2012 ruling on how KPN should be regulated in the fibre-to-the-office (FTTO) market in the Netherlands. Plum assessed whether the ruling was reasonable and in the public interest. This ruling stipulated that KPN must supply its existing passive fibre connections to access seekers (and specified a price[…]
