¿Cómo se puede calcular el alcance máximo de un sistema de comunicación inalámbrica?

Calculating the maximum range of a wireless communication system involves numerous factors and can be a complex process. However, here's a general overview of the key elements involved: 1. Friis Transmission Equation: This equation forms the basis for range calculation and considers factors like; − Transmitter power (PT) in (W) − Gain of transmitting antenna (GTA) in (dB) − Gain of receiving antenna (GRA) in (dB) − Path loss (PL): Measured in dB − System noise figure (NF) in (dB) 2. Minimum acceptable received signal power: the received signal power (RSL) must exceed a minimum threshold. 3. Additional factors to consider: − Terrain and environment − Frequency used − Licensing and regulations - Propagation tools used

• Perform a link budget analysis, accounting for gains and losses in the communication system, including transmitter power, antenna gains, cable losses, and receiver sensitivity. The link budget helps estimate the maximum range under specific conditions. • Factor in fade margin to account for unpredictable signal fluctuations due to environmental conditions. The fade margin ensures a reliable communication link by providing a buffer against signal variations caused by obstacles, interference, or atmospheric conditions.

The provided formula appears to be incorrect. When tested using the given values, the answer is 6.38, not 23.77 10 ^ ((10 - 20 + 90 - 32.44) / (20 * log10 (900))) = 6.38

In conjunction with the link budget & path loss calculations, there are other factors that may play a crucial role in determining the effective range of a wireless communication link. Lower frequencies typically have better penetration through obstacles, but higher frequencies may offer higher data rates. Consider the trade-offs between frequency & range based on the specific system requirements. The height of the transmitting & receiving antennas above ground level can significantly impact range. Matching the antenna polarization enhances signal strength, otherwise signal degradation will occur. The appropriate MCS used for data transmission affects the system's ability to recover information in the presence of noise & can impact range.
