Communications system density and range improvement by signal-strength-directed channel class selection with weighting for minimum capacity consumption
Methods and apparatuses for optimized channel selection are disclosed. In one example, a channel quality is measured of each channel of an available number of channels on which a mobile communication device can transmit and receive. A subset of the available number of channels is allocated to a long range channel class responsive to the channel quality. An RSSI of the mobile communication device is monitored and correlated to a mobile communication device proximity to a base station. A channel is selected from the long range channel class if the mobile communication device proximity is greater than a predetermined proximity.
1. A method of channel selection for a mobile communication device comprising:
measuring a channel quality of each channel of an available number of channels on which the mobile communication device can transmit and receive;
allocating a subset of the available number of channels to a long range channel class responsive to the channel quality;
monitoring an RSSI of the mobile communication device;
correlating the RSSI of the mobile communication device to a mobile communication device proximity to a base station; and
selecting a channel from the long range channel class if the mobile communication device proximity is greater than a predetermined proximity.
2. The method of claim 1 , wherein correlating the RSSI of the mobile communication device to a mobile communication device proximity to a base station comprises observing a sample to sample variation of RSSI.
3. The method of claim 1 , wherein correlating the RSSI of the mobile communication device to a mobile communication device proximity to a base station comprises comparing the RSSI to a predetermined threshold RSSI.
4. The method of claim 1 , wherein the mobile communication device transmits and receives on the channel selected utilizing a DECT protocol, the channel between the mobile communication device and a DECT base station operating independently from other DECT base stations.
5. The method of claim 1 , wherein allocating a subset of the available number of channels to a long range channel class responsive to the channel quality comprises ranking the channels in order of quality and allocating a predetermined number of channels having a highest quality to the long range channel class.
6. The method of claim 1 , further comprising:
allocating a subset of the available number of channels to a short range channel class, wherein each channel of the available number of channels is allocated to either the short range channel class or the long range channel class.
