Channel allocation schemes

<p>In <a href="/facts/Radio_resource_management/AC4jhxu9">radio resource management</a> for wireless and <a href="/facts/Cellular_network/8zA0jQJ9">cellular networks</a>, channel allocation schemes allocate <a href="/facts/Bandwidth_(signal_processing)/7eMDzfJI">bandwidth</a> and <a href="/facts/Communication_channel/MtlxEShV">communication channels</a> to base stations, access points and terminal equipment. The objective is to achieve maximum <a href="/facts/System_spectral_efficiency/GaePAvv9">system spectral efficiency</a> in bit/s/Hz/site by means of <a href="/facts/Frequency_reuse/8zA0jQJ9">frequency reuse</a>, but still assure a certain <a href="/facts/Grade_of_service/qtRLAjeF">grade of service</a> by avoiding <a href="/facts/Co-channel_interference/I95JpU6Y">co-channel interference</a> and <a href="/facts/Adjacent_channel_interference/2SnGEybp">adjacent channel interference</a> among nearby cells or networks that share the bandwidth.
</p><p>Channel-allocation schemes follow one of two types of strategy:
</p>
<ol><li>Fixed: FCA, fixed channel allocation: manually assigned by the network operator</li>
<li>Dynamic:
<ol><li>DCA, dynamic channel allocation</li>
<li>DFS, dynamic frequency selection</li>
<li><a href="/facts/Spread_spectrum/0NKdJX1S">Spread spectrum</a></li></ol></li></ol>
