The link budget defines the range and robustness of a wireless system. The higher the link budget, the better the range that can be achieved. Extra margins in the link budget also ensure a robust wireless system design. Link budget is defined as the dynamic area between receiver sensitivity and transmitter output power. For example, a device with a receiver sensitivity of -100 dBm and a transmitter output power of +3dBm has a link budget of 103 dB. Increased output power of 3 dBm represents a doubling of the output power, which translates to a 1.4x increase in range. Be aware, however, that increasing output power also increases power consumption in the system. While adding a power amplifier to a transceiver with poor receiver sensitivity will increase the link budget it will also cost power consumption. The Microchip AT86RF232 2.4GHz radio transceiver offers high RX sensitivity and TX output power at a minimum of supply current. Device features such as antenna diversity support can further help improve the robustness of the wireless system.
