Future proofing Wi-Fi – the case for more spectrum
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.
700 MHz band plans 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[…]
Radio spectrum licensing in Qatar
The study covered the licensing of all services that required access to the radio spectrum. In addition recommendations were provided on what spectrum and services should be licence exempt. The first part of the study involved a comprehensive benchmarking study of licensing approaches adopted in a number of agreed countries including the UK and the US. […]
Spectrum sharing and pooling
The study was intended to provide advice in respect of spectrum sharing and pooling and the applicability to Defence spectrum and was split up between two work packages; work package one (WP1) looked at the “Spectrum Usage” and work package two (WP2) looked at the “Approaches to Pooling and Sharing”. The purpose of WP1 was[…]
The economic benefits of 1.4 GHz spectrum for mobile broadband in the Middle East and North Africa
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.
Inventory and review of spectrum use: Assessment of the EU potential for improving spectrum efficiency
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[…]
Survey of cognitive radio developments
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[…]
