  A comparative analysis of the observational characteristics of fast radio
bursts at the frequencies 111 and 1400 MHz is carried out. The distributions of
radio bursts by the dispersion measure are constructed. At both frequencies,
they are described by a lognormal distribution with the parameters $\mu =6.2$
$\sigma = 0.7$. The dependence $\tau_{sc}(DM)$ of the scattering value on the
dispersion measure at 111 MHz and 1400 MHz is also constructed. This dependence
is fundamentally different from the dependence for pulsars. A comparative
analysis of the relationship between the scattering of pulses and the
dispersion measure at 1400 MHz and 111 MHz showed that for both frequencies it
has the form $\tau_{sc}(DM)\sim DM^k$, where $k = 0.49 \pm 0.18$ and $k = 0.43
\pm 0.15$ for the frequencies 111 and 1400 MHz, respectively. The obtained
dependence is explained within the framework of the assumption of the
extragalactic occurrence of fast radio bursts and an almost uniform
distribution of matter in intergalactic space. From the dependence
$\tau_{sc}(DM)$ a total estimate of the contribution to the matter of the halo
of our and the host galaxy to $DM$ is obtained $DM_{halo} +
\frac{DM_{host}}{1+z}\approx 60\;{\rm pc/cm}^3$. Based on the LogN - LogS
dependence, the average spectral index of radio bursts is derived $\alpha = -
0.63 \pm 0.20$ provided that the statistical properties of these samples at 111
and 1400 MHz are the same.
