Abstract: A communications system dynamically reconfigurable for RF bandwidth and modulation protocols is disclosed. A server comprises one or more radio head interface modules and a call processing software module adapted to communicate with each other. The call processing software is adapted to perform modulation and demodulation of voice and data streams using one or more air interface protocols. A radio head unit coupled to the radio head interface module communicates with one or more subscriber units. The radio head interface module receives either air interface protocol configuration information, or RF signal bandwidth allocation information, from the call processing software module for one or more communication channels, the information providing a timing trigger and a protocol or bandwidth for one or more communication channels. The radio head interface module reconfigures itself for one or more communications channels, based on the change instructed by the call processing software.

Abstract: A frequency hopping communications system is disclosed. A server is adapted to have one or more radio head interface modules and a call processing software module. The call processing software module performs modulation and demodulation of voice and data streams using one or more air interface standards. A radio head unit is coupled to the radio head interface module over one or more transport mediums and communicates with one or more subscriber units using the one or more air interface standards. The one or more radio head interface modules, are adapted to receive frequency channel hopping information, including a channel and a time to hop trigger, from the call processing software module for one or more of a plurality of communication channels.

Abstract: The present invention relates to dynamically configured wireless communication systems. In particular, in one embodiment, dynamically configured up and down converters in a communication system is provided. The method comprises receiving a request to change a protocol in a communication channel. Obtaining one or more parameters associated with the change in protocol of the communication channel and applying the parameters to the up and down converters.

Abstract: Systems and methods for maintaining data stream synchronization are provided. A system comprises one or more radio head interface modules and a call processing software module each adapted to communicate with each other. The call processing software module performs modulation and demodulation of voice and data streams using one or more air interface standards. The call processing software module communicates a forward data stream to a first radio head interface module. The forward data stream comprises a plurality of data samples representing voice and data streams and a plurality of fixed synchronization words. When the first radio head interface module does not observe the receipt of a first fixed synchronization word of the plurality of fixed synchronization words word from the call processing software module when expected, the first radio head interface module concludes that it has lost synchronization with the call processing software module.

Abstract: Methods and systems for reconfiguring communications systems are provided. A communications system comprises one or more radio head interface modules and a call processing software module. The one or more radio head interface modules are adapted to communicate with the call processing software module. The call processing software module performs modulation and demodulation of voice and data streams using one or more air interface standards. The one or more radio head interface modules receive reconfiguration parameters from the call processing software module for one or more logical channels. The call processing software module and the one or more radio head interface modules communicate one or more pages of data samples to each other, each of the one or more pages of data samples having a page header. Reconfiguration parameters are contained in the page header.
