Troll Systems design engineers apply your RF link requirements and use that data to calculate a link budget.
A link budget is the accounting of all of the gains and losses from the transmitter, through the medium such as free space, cable, waveguide, fiber, etc., to the receiver as well as the signal losses that are incurred from TX source to the RX site from line of sight, terrain, atmospheric loss etc., in a telecommunication system accounting for the attenuation of the transmitted signal.
This attenuation is due to propagation, as well as the antenna gains, feedline and miscellaneous losses. Randomly varying channel gains such as fading are taken into account as well by adding a, margin depending on the anticipated severity of its effects. The amount of margin required is reduced by through our antenna diversity features and signal tracking configuration.
Soon we will be introducing a tool here in which you will be able to calculate your own link budget.
