1 General Description
1.1 Feature
This document describes briefly the board level operations, key features and the
environment of the M4 Platform. The purpose of this platform is the verification of LG
LTE ASIC, namely ‘L1000’, and the evaluation of LG UE system performance. The
further details about the characteristics and functions of L1000 are available on other
documents.

LTE device has 2 external RF connectors in order to measure wired RF performance
characteristic.
It is configured that LTE RF front-end part is two external RF port; LTE main RF port
and LTE MIMO RF port.
LTE Main ANT mobile SW
If you want to test wired LTE RF performance, you c an use this external RF
port(mobile switch).

3.4 External Power description
3.4 External Power description
To operate an d charge the battery, plug the AC Adapter into a standard wall outlet
and connect it to the LTE trial device via the DC input jack Connector.
External power supply is DC input jack or TA. This power supply specification is
below.

3.5 Battery description
Our LTE Trial device has a battery is used f or operating LTE modem part.
Battery Capacity for used in LTE is 2400mAh.
If the battery’s charge is completely run down, it takes 6 to 7 hours to fully recharge.
But this battery capacity is not enough to operate LTE capability; you should external
power supply, which is TA (Travel Adap tor). The mandatory power supply of the LTE
UE is supplied by TA which is distributed by the LGE.
