1.1.1 Data rates
Under ideal deployment conditions (low line of sight, low interference, and low moisture content), the
SR1410 router can operate over a range of up to 1 km or provide a high-speed connection of 100 Mbps
The range also depends on the type of antenna used. The maximum data rate for a link decreases as the
operating range increases.
When planning a wireless router link, take into account the maximum distance and data rates for the
various antenna options.

1.1.2 Radio Path Planning
The wireless router link requires a “radio line of sight” between the two antennas for optimum
performance.
The concept of radio line of sight involves the area along a link through which the bulk of the radio
signal power travels. This area is known as the first Fresnel Zone of the radio link. For a radio link, no
object (including the ground) must intrude within 60% of the first Fresnel Zone.
The following figure illustrates the concept of a good radio line of sight.
