This article describes the differences between Standard COR IBRs & Active Standalone GPS versions of the IBR600LE-PWD & IBR600LP-PWD.
On standard versions of COR we support GPS and reception is received on the auxiliary (2nd) modem antenna port. Our default modem antennas don't provide great GPS reception. There is a 3rd dedicated GPS antenna port on the module inside the COR (that is used in regular versions or COR). In the PWD versions this dedicated GPS port is wired to one of the WiFi antenna ports, which is now the new dedicated GPS port. WiFi no longer uses that port so it is only running with 1 antenna which is a major issue for most GPS applications. The dedicated GPS port is powered (PWD) from COR (meaning powered at 3.3V, 100mA max). This means an active GPS antenna can be attached to the dedicated GPS port and placed on top of a vehicle providing a much stronger signal and low attenuation. Active GPS antennas are readily available in the market.
Main differences between COR PWD and COR:
1x1 n WiFi instead of 2x2 n WiFi
Active GPS antenna port at 3.3V, 100mA max (SMA adapter included to convert WiFi port to standard SMA active GPS port)
The GPS function is turned on by default, where as in the standard COR the default is disabled
IBR600LE-PWD & IBR600LP-PWD Setup:
The IBR600LE-PWD & IBR600LP-PWD ship with 3 antenna; 2 cellular and 1 WiFi, and a R-SMA to SMA adapter for connecting a GPS antenna. It does not ship with a GPS antenna. IBR600LE-PWD & IBR600LP-PWD WiFi and GPS Antenna Connectors
