LMU-303x Hardware & Installation Guide
2.2.5 PULS™
PULS™ (Programming, Update and Logistics System) is CalAmp’s web-based maintenance server offering
out-of-the-box hands free configuration and automatic post-installation upgrades. PULS™ provides a means for
configuration parameters, PEG-2 scripts, and firmware to be updated Over-The-Air (OTA) and allows CalAmp
customers to monitor unit health status across your customers’ fleets to quickly identify issues before they
become expensive problems.
2.2.6 LMU Manager™
LMU Manager is the primary configuration tool in the CalAmp system. It allows access to almost every feature
available to the LMU-303x™. Unlike the backend software, it has the option of talking directly to an LMU303x™
or making a request forwarded by the LM Direct™ server.
For further details on using LMU Manager, please refer to the LMU Manager Users Guide.
2.2.7 Wireless Data Network
The Wireless Data Network provides the information bridge between the LM Direct server and the
LMU303x™s. Wireless data networks can take a variety of forms, such as cellular networks, satellite systems
or local area networks. At this point in time, the networks available to the LMU-303x™ are:
LTE (Long-Term Evolution)
Long-term evolution (LTE) is the latest and rapidly growing global data transmission technology.
Based on GSM and UMTS/HSPA standards, LTE is a standard of high-speed wireless data
transmission and communication. Continuously evolving, LTE advancements continue to push data
capacity and user experience on a global scale. With a peak downlink rate of 300 mbps, uplink rate of
75 mbps, LTE sits in 1.4 MHz to 20 MHz bands, while also supporting FDD, TDD, and not sacrificing
data capability.
2.2.8 LMU-303x™
The LMU-303x™ is responsible for delivering the location and status information when and where it is needed.
Data requests can come from any of the following sources:
PEG-2™ script within the LMU-303x™
A location or status request from the LM Direct server
A location or status request from LMU Manager
A request made from a host device such as a laptop, PDA or MDT
