Key Features
Multiple Beacon Confi guration
Each unit contains four independent beacons. These can be all in the same band or two of one band and two of another.
Detected RF Power Shutdown
The product contains an RF power detector for each transmitter that can be used to sense the power being transmitted by the DAS.
Loss of the DAS requires that the beacon be shut down in order to provide some possibility for mobile devices to connect to the low level
signal of the macro network.
The shutdown threshold is set by the user. When the detected power falls below the set threshold the transmit power of all beacons is
shut down and an alarm is issued. When the power rises above the threshold the beacons are turned back on.
Timing Reference Source
A GPS derived timing reference is always required for the proper operation of the Co-co-pilot beacon. That timing reference can be
provided by one of the following:
• An optional internal GPS receiver
• An optional internal CDMA timing receiver
• The CSI supplied external CDMA Timing Reference Receiver
• The CSI supplied external precision GPS Timing Reference (Spectrum Instruments TM-4)
• Any user-supplied GPS Receiver capable of providing a TTL compatible even second tick aligned to GPS (not UTC)
time.
Control Parameter Details
Master Shutdown
The Master Shutdown shuts down the transmissions from all beacons in the product.
Timing Reference Selection
There are three alternatives for the timing reference source and all beacons in the product use the same reference.
• Internal GPS
• Internal CDMA
• External Even Second Sync
The choices that are available will depend on the product type as follows:
-MX- “External” only
-MG- “External” and “Internal GPS”
-MO- “External” and “Internal CDMA
The default choice will also depend on the product type as follows:
-MX- “External”
-MG- “Internal GPS”
-MO- “Internal CDMA
Selecting “Internal GPS” enables the use of the internal GPS receiver. An appropriate antenna with a clear view of the sky must be
connected to the “Timing In” connector of the Co-pilot beacon. This choice is only available if the unit includes the optional GPS timing
reference.
Selecting “Internal CDMA” enables the use of the internal CDMA receiver. Either an appropriate antenna, or a cable carrying a valid
CDMA Base Station signal, must be connected to the “Timing In” connector of the Co-pilot beacon. This choice is only available if the unit
includes the optional CDMA timing reference.
Selecting “External Even Second” enables the use of a TTL compatible even second pulse via the “EST In” connector of the Co-Co-pilot
beacon. The rising edge of the pulse is used as the time reference and must be aligned with the start of the even second of GPS (not
UTC) Time.
The even second tick provided by the selected Timing Reference will appear on the “EST Out” connector.
