Plum and Farncombe prepared a practical guide to digital switchover to supplement the information already published by the ITU and others. The guide focuses on a set of practical measures that anyone undertaking switch over / switch off must address, drawing on best practice from around the world.
Plum was commissioned by Cisco to conduct a study on whether there is a case for additional 5 GHz spectrum for unlicensed Wi-Fi use in Europe.
Plum evaluated alternative harmonised band plans, 2×40 MHz versus 2×30 MHz, for the 700 MHz band for the ITU-R Region 1. The study looks at the economic issues to inform the GSMA regarding the best candidate from these two band plans. The study focusses on the costs and benefits from an operator perspective as well as[…]
Plum assessed the economic benefits from using the 1.4 GHz band for a supplemental downlink for the delivery of enhanced mobile multimedia and broadband services in the Middle East and North Africa region.
Plum provided the lead economics input and Aegis provided the lead technical input to a study led by WIK to develop a prototype spectrum inventory. The study involved collecting data on spectrum use in the frequency range 400MHz to 6GHz and developing measures of spectrum efficiency in order to identify bands that might be used[…]
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[…]
Plum prepared a paper for Vodafone assessing the potential consequences of different spectrum assignment approaches being considered in sub-Saharan Africa. In particular the paper discusses three case studies: Kenya, where a single, monopoly wholesale LTE network based on a public private partnership (PPP) model was being considered by the Government Ghana, where incumbent operators were[…]
The study was undertaken to provide ComReg with an independent view on whether all the GSM-R spectrum band should be awarded for a planned railway communications network deployment in Ireland. In conjunction with ClearCinCom an assessment was made of the GSM-R network design requirements provided, including the need to support ETCS Level 2 applications, and the associated[…]
Plum reviewed and responded to the comments received from interested parties in response to ComReg’s consultation Document 11/80, on the future of the 2.6 GHz radio spectrum band. This consultation sought comments on a report, Document 11/80a, that considered the technical feasibility of the 2.6 GHz band being shared by MMDS and Next Generation Mobile[…]
Plum and Network Strategies were commissioned by the Department of Broadband, Communications and the Digital Economy (DBCDE) to conduct a study of spectrum trading. Plum conducted an assessment of spectrum trading in Australia, including a description of the current environment, examples of past trades and key lessons from these trades. This helped to identify the[…]
