DAB receiver test methods

It was being proposed that DAB receivers should carry some form of certification mark, to indicate an acceptable level of performance.  To allow such a scheme, it was necessary to develop a robust and repeatable method for receiver sensitivity testing.  This study compared the sensitivity measurements obtained using two different test methods – one using[…]

DTT licence bid

This study provided supported for a DTT licence bid in Malaysia.  Specifically sections of the Sapura licence proposal concerning planning standards and coverage issues were drafted.  Coverage predictions for some of the sites proposed were run using the in-house planning tool, Aardvaark, to model the proposed SFN (Single Frequency Network).

This helped to identify the[…]

Valuation of mobile broadband spectrum in Australia

Plum supported the Department of Broadband, Communications and the Digital Economy (DBCDE) with the estimation of value for the 700 MHz and 2.5 GHz spectrum bands in Australia. The work was performed in conjunction with Dr. Melvyn Weeks of the University of Cambridge. To derive estimates of spectrum value for delivery of mobile broadband services[…]
