Flexible Spectrum Access Methods

This report, commissioned by the UK Spectrum Policy Forum, considers future flexible spectrum access methods.  Flexible access and spectrum sharing were key features of the UK Strategy Published in 2014. In this report we consider the state of play on spectrum access in the UK (from dedicated national licensing through to licence-exempt), techniques for enabling[…]

The compatibility of LTE services and VSAT receivers

Plum have recently collaborated with Huawei in undertaking a number of studies intended to clarify options for spectrum sharing in C-band. The report linked here addresses issues relating to the co-existence of LTE services and satellite downlinks in the same, or adjacent, spectrum. The report describes realistic field trials which illustrate the potential for geographical[…]

Review of licence fees in the Australian 17.3-51.4 GHz band

Plum was engaged by the Australian Communications and Media Authority (ACMA) to review the current taxes for the Ka (17.3-51.4 GHz) spectrum band, and to investigate how existing taxation arrangements could be improved. Plum concluded that the Ka band was unlikely to become congested in the near future, and that many frequency bands have witnessed[…]

Competition, mergers and site costs: lessons learned from the iterated cost model

Recently we’ve been working on expanding the capability of one of our mobile network models – the iterated cost (or bootstrap) model. In a nutshell, this model treats buyers and sellers of mobile data as rational economic agents. When the cost of supplying data falls, consumers buy more of it. Similarly, operators invest in additional[…]

All change: how 5G will shake up spectrum management

Although the technology underpinning 5G is still in development, it is likely to offer additional capacity and efficiency in the radio access network much as preceding generations have. However, with ever-growing traffic demand, challenging competition, and the rise of OTT services, operators are finding it increasingly difficult to sustain healthy business margins. There is uncertainty[…]

Valuation of mobile broadband spectrum in Taiwan

Plum was part of the study team which advised the National Communications Commission on the auction of the 2.6 GHz band in Taiwan. Plum’s consultants led the valuation work, which employed a combination of techniques including international benchmarking, econometrics, avoided cost modelling and enterprise valuation. The work also included an assessment of the potential impact[…]
