Set up the base station using either the tripod or T-bar mounting method. You must use an external radio antenna kit for the internal 450 MHz or 900 MHz radio. To avoid interference between the 900 MHz radio and GPRS transmissions, do not mount the external radio antenna within 1 m (3.3 ft) of the GSM antenna.
Trimble recommends that base stations that are connecting from a portable, daily-use setup are treated as unmanaged base stations and those used for permanent or semi-permanent setups where the receiver will be in the same place for a longer period of time are treated as managed base stations.
Check the base station details to ensure that the base radio is indicating it is connected to IBSS through an SNM941 Connected Site Gateway. Your base station is now up and running. Log into to check the status. Equipment: Procedure: Insert the SIM card into the SNM940 modem, if required, and then reseal the unit.
This is when the PSU is no longer powering the PA, which is the main power draw, but still needs to power other electronics. The current target for low-load efficiency is about 30 W. Some OEMs would like to see that drop to nearly 10 W.
This technique reduces opex by putting a base station into a “sleep mode,” with only the essentials remaining powered on. Pulse power leverages 5G base stations’ ability to analyze traffic loads. In 4G, radios are always on, even when traffic levels don’t warrant it, such as transmitting reference signals to detect users in the middle of the night.
Open the SNM940 web interface in an Internet browser using the default IP address of 192.168.33.1. Start the SCS900 software and open a site containing the control point for the base setup, if available, or a new site if setting up the base on an arbitrary point. Start a new work order. Mode: Base.
