The present invention provides a radio interference indicator comprising a controller for processing an instruction and a radio signal receiver coupled to the controller to receive or detect a radio signal. An indicating element is coupled to the controller to indicate the level of the radio signal to allow the user knows the quality of the background the radio signal.

Radio interference indicator

The dual mode positioning system comprises multiple wireless network devices, one of the multiple wireless network devices including a GPS receiver. DSS is coupled to the multiple wireless network devices and an operation mode switch is also coupled to the multiple wireless network devices including a GPS receiver. A satellite GPS receiver coupled to the operation mode switch. The satellite GPS receiver is operated in an indoor area confined by walls with wide FOV (field of view) glass window, the operation mode switch switching to GPS mode for the satellite GPS receiver receives signals from greater than 3 satellites. Moreover, the satellite GPS receiver is operated in an indoor area confined by concrete walls or walls with narrow FOV glass window, the operation mode switch switching to Joint GPS/WPS mode for the satellite GPS receiver cannot receive signals from greater than 3 satellites.
