Measurement of Coherence Bandwidth in UHF Radio Channels for Narrowband Networks

Table 2

Characteristic values of rms delay spread for UHF narrowband channels.

Parameter	City	Hilly terrain	Flat terrain
Median value [μs]	0.612	0.46	0.4
Value exceeded in 10% of observation time [μs]	1.63	1.15	0.49
Value exceeded in 1% of observation time [μs]	4.07	3.09	0.8

Values greatly influenced by limitations of PDP measurement method (overestimated).
