A comparative analysis of the observational characteristics of fast radiobursts at the frequencies 111 and 1400 MHz is carried out. The distributions ofradio 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 thedispersion measure at 111 MHz and 1400 MHz is also constructed. This dependenceis fundamentally different from the dependence for pulsars. A comparativeanalysis of the relationship between the scattering of pulses and thedispersion measure at 1400 MHz and 111 MHz showed that for both frequencies ithas 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 obtaineddependence is explained within the framework of the assumption of theextragalactic occurrence of fast radio bursts and an almost uniformdistribution of matter in intergalactic space. From the dependence$\tau_{sc}(DM)$ a total estimate of the contribution to the matter of the haloof 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 - LogSdependence, the average spectral index of radio bursts is derived $\alpha = -0.63 \pm 0.20$ provided that the statistical properties of these samples at 111and 1400 MHz are the same.
