Driving Force (DF)
= Function (soft and hard factors)
= M (r, p, m, o) * H (G, g)
DFm= Mm (r, p, m, o) * GDP/capita * T
where T, Terrain Factor (0 < T =< 1) ,
is a retarding factor. For comparing cities,
GDP/capita could be in PPP.
Technology, as reflected in pricing, device attributes and quality, is not explicitly expressed. Consumers do not care about technology per se.
Applying metrics to IPTV in a hypothetical city :
r = 5, p = 4, m = 5, o = 3.9
(“o” being the geometric mean of the 4 sub-factors:
Content = 5, Consumer habits = 3,
Device attributes = 4, Quality = 4)
So, geometric mean of the 4 soft factors (r, p, m, o) = 4.4
(Any one “bad” factor or sub-factor ruins the growth; zero point is allowed and one zero reduces DF to zero.)
DAB and DTT
T (city) = Function (D, H)
= Function of √(D*H)
ie using geometric mean
A = area (sq. km) available for construction,
(Skyline ranking: www.emporis.com/en/bu/sk/st/sr
Points are given to buildings of 12 floors or more,
with a max. of 600 points for a builidng of 100+ floors.)
for n = 10. Changing n does not alter the ranking.
(i) Satisfactory outdoors (VHF 11B, SFN, 384 kbps DAB video);
(ii) Satisfactory outdoors (UHF Ch. 47,
DVB-H, QPSK, code rate ½), for 90% locations. Indoor reception: extra 16 dB mean loss at 14 locations and reception failed at 50% locations, at distances > 5m from the first wall of building, near ground levels;
(iii) Satisfactory outdoors (using similar parameters), but indoor reception requiring extra 16 dB signal could not be assured in the vicinity of the test routes.
(Additional results have been released in March, 2008)
