FAQ’s

What is the minimum required signal strength for a given link budget calculation?

The minimum required signal strength for a given link budget calculation is determined by the total losses in the link (including antenna gains, cable losses, etc.) and the desired signal-to-noise ratio.

What factors need to be taken into account when calculating a link budget?

The factors that need to be taken into account when calculating a link budget include the transmit power, receiver sensitivity, antenna gains, path loss, cable losses, and any other environmental factors that may affect the signal.

How can antenna gain be accounted for in a link budget calculation?

Antenna gain can be accounted for in a link budget calculation by multiplying the total power transmitted by the antenna gain, which is expressed in decibels (dB). This will give the effective isotropic radiated power (EIRP) of the link.

How is temperature taken into consideration when calculating a link budget?

Temperature is taken into consideration when calculating a link budget because it affects the signal strength and can cause signal loss. Temperature can cause the atmosphere to become more or less dense, which can affect the signal’s propagation and cause it to be weaker or stronger.

How can the effects of atmospheric noise be included in a link budget calculation?

The effects of atmospheric noise can be included in a link budget calculation by estimating the noise power at the receiver antenna and subtracting it from the total received power. This will give the signal-to-noise ratio (SNR) of the link, which can then be used to calculate the link budget.

What is the process for completing a link budget analysis?

The process for completing a link budget analysis involves calculating the total power received at the receiver, taking into account the power transmitted, the antenna gains, the cable losses, and the atmospheric losses. It also involves calculating the signal-to-noise ratio, which is the ratio of the received signal power to the noise power. Finally, the link budget analysis should include a margin analysis, which is the difference between the required signal-to-noise ratio and the actual signal-to-noise ratio.
