Conversion Table
[!info] Logarithmic Conversion Definition of Bell: $1B = \log_{10}\frac{P_1}{P_2}$ Therefor a Dezibell:
P_{dB} = 10\cdot\log_{10}\frac{P_1}{P_2} \longleftrightarrow \frac{P_1}{P_2} = 10^\frac{P_{dB}}{10}
Value Conversion according to:
P_{dB} = 10 \cdot \log_{10} x| Value | DB | Note |

[!info] SIR - Signal to Interference Ratio
SIR = \frac{1}{6} (3k)^{\frac{\gamma}{2}}Cluster Size k:
k = \frac{1}{3}(\frac{D}{R})^2with D:
D = R \cdot \sqrt{3k}Testing k is done by:
k = i^2 + ij + j^2; \quad i,j\in\mathbb{N}
