Impact of building materials on radio waves

There is an increasing expectation that wireless services should be ubiquitously available, with seamless connectivity whether the user is indoors or outdoors.  It is therefore important that the impact of buildings on the propagation of radiowaves be understood and reliably characterised.  Although many measurements have been made over the decades, it is not always easy[…]

The value of 900 and 1800 MHz spectrum in Thailand

Plum was a member of an ITU team that advised the NBTC, Thailand on spectrum valuation methodology, derived spectrum values and advised on reserve prices for the 900 MHz and 1800 MHz bands. Reserve prices provide starting prices for different lots in an auction and so they are not an estimate of the value that[…]

Platform neutrality and interoperability

Plum prepared a report on platform neutrality, openness and interoperability – and the potential policy issues related to these areas – for a California-based Fortune 500 Company. The terms open, neutral and interoperable appear frequently in discussions of the technology/ICT sectors, yet terms are not uniformly defined. The first challenge therefore lies in defining these[…]

Plum Insight: Do you need a mobile data forecast to estimate spectrum demand?

Spectrum demand is a key input to decisions over spectrum allocation and assignment. Yet estimates of spectrum demand are sensitive to assumptions regarding future mobile traffic, which are uncertain. In this Insight we consider an alternative approach to modelling the demand for spectrum which dispenses with the need for a data traffic forecast. Instead, the[…]
