Systems and methods of dynamic segregation of managed wireless resources by traffic type
View Patent ↗Systems and methods are described for segregating airlink resources in a wireless communication network by traffic type. When voice data and traffic data are sent simultaneously in a wireless network using a limited set of frequency resources, the data traffic can cause unacceptable interference in the voice traffic. Accordingly, transceivers share their voice traffic and data traffic demands and may allocate portions of an airlink resource into resource zones for exclusive use by voice traffic and data traffic. Within each resource zone, the transmission can be optimally managed for each traffic type, and interference between voice traffic and data traffic is reduced.
