This is what I was referring to previously. In practice,
service to handhelds, even in DVB-T countries, will
likely be provided over frequencies set aside for that
purpose, rather than cannibalizing room from the DTT
Freeview spectrum.
As to this:
"Each mobile cell could only support around seven
simultaneous viewers, said Nwana. '3G does not scale,'
she added." I agree. That's why Qualcomm developed the
broadcast mode for cdma2000, which they call FLO.

BT poised to announce mobile DTV launch
BT is reportedly set to announce the UK launch of a broadcast
mobile digital television service. The launch follows a
four-month trial, using Digital Audio Broadcasting (DAB)
spectrum. Last month BT said the pilot, conducted with mobile
operator Virgin Mobile, demonstrated clear consumer demand
for mobile television.
The Financial Times said BT would team up with Microsoft and
Virgin Mobile to roll-out the service, and would confirm the
launch tomorrow at Barcelona's 3GSM conference, the mobile
phone industry's biggest annual gathering.
According to the FT, BT and Virgin Mobile, which is the
subject of a takeover offer by cable group ntl, plan to
launch the service by the middle of the year. At least five
television channels will be on offer, similar to the number
in the pilot which broadcast television and radio channels to
1,000 triallists using DAB-enabled phones within the M25 area.
Just under three quarters of participants said they would be
prepared to pay for the service on their current network if
the service was priced competitively; 38% were prepared to
switch networks to receive the service. Over three quarters
of the pilot users tuned into digital TV and radio on their
mobile on a weekly basis or more often, with the average
length of TV viewing being more than one hour per week.
DAB's big advantage over DVB-H, the standard trialled by
Virgin's mobile rival O2 and transmission group Arqiva in
Oxford last year, is that spectrum is already available via
digital radio whereas DVB-H requires an allocation from
Ofcom-and that could have to wait for the switching off of
analogue television signals between 2008 and 2012.
Meanwhile, Arqiva's mobile media chief Dr Hyacinth Nwana
told The Sunday Times that broadcast solutions for mobile
television had a big advantage over its delivery via 3G
networks. Nwana said each of the UK's five 3G networks
could only support around 100,000 viewers, a fraction of
the operators' combined 15m subscribers.
Each mobile cell could only support around seven
simultaneous viewers, said Nwana. "3G does not scale,"
she added.
