Introduction
1.1 Purpose and Use
The Speed HPRx450 (FCC ID: MLLSPEEDHPRX450) is a data link transceiver that is
used for data transfer in Miltel’s utility consumption readings collection system. This
device is installed on-site by a professional field technician, thus it includes technical
terms. The equipment is not to be installed by a non-professional individual that has
not been trained and authorized.
1.2 System General Description
The Speed HPRx450 system is a computerized fully automatic radio device. It
requires no human intervention after initial installation. The device acts as a store-
and-forward radio relay. The Speed HPRx450 captures any transmission from a
Speed HPTx transmitter and, after validating the message, transmits the message
again. The Speed HPRx450 relays information from meter reading transmitters to
regional concentrators (which are equipped with a radio receiver). The concentrator
transfers the data to the central computer for data collection and for further analysis
and reporting.
