Plum advised the Utilities Regulatory and Competition Authority of Bahamas on the revision of its spectrum fees schedule for licensed services. The main purpose was to ensure that the spectrum fee structure and fee levels would fulfil a suitable balance of objectives, including the optimal use of the radio spectrum, universal service and affordable access[…]
The GSMA wanted to gain an understanding of potential demand for DTT in sub-Saharan Africa within the band 470 – 694 MHz. In order to help the GSMA to achieve this aim, the study undertook a review of DTT requirements within an example set of countries and the implications for spectrum release based on RRC-06[…]
The aim of the study was to gain a better understanding of radio signal variability in different clutter types in order to aid the modelling of potential coexistence issues with DTT using the UK DTT planning model. Using our survey vehicle extensive measurements at different antenna heights and locations were carried out to gain detailed understanding[…]
A number of sharing studies were undertaken to identify the potential to allocate 5855–5875 MHz for Broadband Direct-Air-to-Ground Communications (DA2GC). One of the studies investigated adjacent band operation to radiolocation operating in the band 5250–5850 MHz. The main radiolocation use is military and the analysis concentrated on fixed land-based, ship borne and transportable platforms operating[…]
The study involved a statistical analysis of the ITU Space Radiocommunications Stations (SRS) database (BR IFIC 2762, 4 February 2014) in order to benchmark differing satellite filing patterns between administrations. The analysis method adopted enabled filing statistics to be presented principally by administration, time, frequency band and orbital slot. The analysis was conducted for the[…]
