ARLA/CLUSTER: Ofcom apresenta estudo de frequências e propagação para futuro radios portateis

Ofcom release propagation and frequency reports

Ofcom has released two reports, they cover propagation of radio
signals in buildings and frequency band support for future mobile
handsets

While building entry loss is an increasingly important parameter in
link planning, it is poorly-characterised, partly due to the wide
variability within and between buildings. Data relating to domestic
buildings is particularly poorly represented.
Ofcom have expressed concern that the increased use of
energy-efficient construction practices may be causing building entry
loss to increase, and this study was commissioned to address this
question.

The second report describes the findings of a study carried out for
Ofcom by Aegis Systems and RTT Programmes, addressing the key factors
affecting multi-band support in future cellular handset devices, in
particular the likely relationship between the number of frequency
bands supported and the RF cost and performance of a user device over
the next ten to fifteen years.
