Hi Jeroen,
I agree but there a) people who don't like the current bit rate at which =
the services are run (between 128 and 192kb/s) b) although you see lots o=
f DAB portables you never see a battery operated DAB radio c) although lo=
ts of people do have excellent indoor antenna reception on a telescopic r=
od, they generally reckon the current low power VHF Band III signals shou=
ld be up to 9dB higher. Set against that my analogue FM is crap and the D=
AB versions of the same stations are flawless: domestic harmony in the mo=
rnings. d) Its very clear why it is a success: same business model as Fre=
eview. New digital only stations, simulcast of existing services, no subs=
cription and under =A399.
Heretically if you were starting digital radio today you would NOT use Eu=
reka 147: you would and some countries are planning to, use DVB-H as its =
6.8 times more efficient than DAB (spectrum occupancy+audio coding) and t=
here will be scale economies from simultaneous deployment of DVB-H in cel=
lular systems. Of course it too uses that notorious but highly industrial=
ised and effective multicarrier system!!
And, of course, DVB-H is probably better suited for battery operated digi=
tal radios...
Kind Regards,
Dermot Nolan
