    Engineers (IEEE) and International Telecommunications Union (ITU), who are chartered with developing standardized calculations. The Alvarion Link Budget Tool is built upon these formulas; however, it is important to bear in mind that the calculations are an estimate only, with relatively large standard deviations (5-15 dB) depending on the exact deployment scenario and obstacle characteristics.

  • Page 95: Table 5-2: Availability Versus Outage Time

    99.99%. The tool automatically calculates the estimated required fade margin over distance to achieve this availability. A key advantage of the Alvarion product is that it features a transmission correction scheme called Automatic Repeat Request (ARQ). The ARQ algorithm essentially detects when a packet(s) has been lost, due to fading, and makes a request to the remote system to re-transmit the lost packet(s).
