The power supply should have good regulation with < 200mV
drop at 2.2A.
Adequate supply decoupling (10,000uF min.) is added at
terminal connector to reduce ripple and smooth supply voltage
steps.
The power supply be capable of supplying non-ideal current
consumption conditions of up to 2.2A for up to TBD seconds
and with a duty cycle (set by data usage) ~ 30% maximum.
Multiple pins are assigned to both power and ground
connections for the modem. Connection of all designated pins
to the appropriate supply or ground in the host/terminal is
necessary to accommodate modem current requirements.
The host/terminal must provide a continuous supply.
The modem is compliant with the Mobitex Power Save Protocol.
The modem exists in the lowest power state possible (standby state)
while still providing uninterrupted service. By de-asserting the
HOSTPWR_ON signal, the modem disconnects from the network
then enters a near-zero power state. The modem resets if the power
source is cycled. This can cause network service issues, since the
modem might not have had a chance to de-register. The modem
spends the majority of time in sleep mode.
Conservation
In installations requiring power conservation (such as, when the
modem is powered from a battery or solar cell), you must monitor
modem power consumption in various operating states. Even though
the Boomer-III OEM modems are designed for minimal power
consumption, by using the network Power Save protocol offered by
Mobitex networks you can further reduce power consumption.
Note: The on-board LEDs may be disabled to minimise power
consumption. All LEDs will flash on start-up and the Receive and
Transmit LEDs will flash on power down regardless of the state of the
LED disable control.
Power Save Protocol
The modem typically uses current provided by the host/terminal
battery. For the product to be usable for a reasonable period in portable
applications, the host/terminal battery power must be conserved. To
meet this requirement, the modem uses Mobitex Power Save protocol.
The Power Save Protocol defines the following four modem power
consumption states:
Off
Operating State
Standby State
Quick Channel Monitoring
