In radio resource management for wireless and cellular networks, channel allocation schemes allocate bandwidth and communication channels to base stations, access points and terminal equipment. The objective is to achieve maximum system spectral efficiency in bit/s/Hz/site by means of frequency reuse, but still assure a certain grade of service by avoiding co-channel interference and adjacent channel interference among nearby cells or networks that share the bandwidth. Channel-allocation schemes follow one of two types of strategy: 1. * Fixed: FCA, fixed channel allocation: manually assigned by the network operator 2. * Dynamic: 3. 1. * DCA, dynamic channel allocation 4. 2. * DFS, dynamic frequency selection 5. 3. * Spread spectrum (en) 在用于无线和蜂窝网络的中，信道分配方案分配到基站、接入点和终端设备的带宽和通信信道，目标是实现比特/秒/赫兹/台站级别的頻譜效率最大化，但仍通过频率重用保证一定的服务等级，避免共享带宽的临近小区或网络中的和。 信道分配方案两种策略类型之一： 1. * 固定：固定信道分配（fixed channel allocation，FCA）：网络运营商手动分配 2. * 动态： 3. 1. * 动态信道分配（dynamic channel allocation，DCA） 4. 2. * 动态频率选择（dynamic frequency selection，DFS） 5. 3. * 扩频 (zh) |

在用于无线和蜂窝网络的中，信道分配方案分配到基站、接入点和终端设备的带宽和通信信道，目标是实现比特/秒/赫兹/台站级别的頻譜效率最大化，但仍通过频率重用保证一定的服务等级，避免共享带宽的临近小区或网络中的和。 信道分配方案两种策略类型之一： 1. * 固定：固定信道分配（fixed channel allocation，FCA）：网络运营商手动分配 2. * 动态： 3. 1. * 动态信道分配（dynamic channel allocation，DCA） 4. 2. * 动态频率选择（dynamic frequency selection，DFS） 5. 3. * 扩频 (zh) In radio resource management for wireless and cellular networks, channel allocation schemes allocate bandwidth and communication channels to base stations, access points and terminal equipment.
