<h1>Downlink Diversity</h1>

<p>PrimeSite has a downlink diversity function, which offers
improvements in air interface link performance.</p>


<p>The PrimeSite has two RF transmitters, one connected to
each antenna. In the downlink diversity technique, the transmission of successive
frames is altered between the antennas. Thus the MS receives the signal first
from one antenna and then the other. If the MS is in a fade on the radio path
from one antenna, it will probably still get a good signal from the other
antenna.</p>


<p>The downlink diversity can be configured on or off by PrimeSite
hardware database. Downlink diversity is available on the PrimeSite basic
configuration. There are always two transmitter amplifiers available. The
downlink diversity serves as redundancy for power amplification function.</p>
