1.3 Power supply
The option board received a 5V power supply from the MLB. It generates from it a 3.3V/1.2A supply and a 1.8V/0.8A
used by the carrier board and the Galileo module.
1.3.1 Regulator 3.3V
From 5V, generate 3,3V power supply used by the Galileo module and the level-shifter.
1.3.2 Regulator 1.8V
From 3.3V, generate 1.8V power supply used by the Galileo module, the slow clock and the level-shifter.
1.4 Level shifter
The level shifter is used to change the 1.8V signals coming from the Galileo module to a 3.3V signals compliant with
the MLB signal requirements, and vice-versa.
The signals converted from 3.3V to 1.8V and 1.8V to 3.3V are as followed:
•
WIFI_PWR
•
WLAN_IRQ
•
BT_PWR
•
BT_RX
•
BT_TX
•
BT_RTS
•
BT_CTS
Notes:
(1) The CPU on the MLB is configured to work with 1.8V signals. In this case the SDIO signals out of the Galileo
module do not need to be modified.
(2) Provision is made to convert the CLK_32kHz and all SDIO signals via the level shifter through uncounted
resistors.

RC12
C12 C12
C12 is an embedded wireless device platform that uses a 90 PAD Land Grid Array (LGA) form factor to allow for a low
cost solution to mount highly integrated chipsets or OEM/ODM MODULES
MODULESMODULES
MODULES onto Intermec products. Galileo uses
solder-down re-flow mounting only to a host MLB – there are no screws, digital or RF connectors. Test jigs are required to
operate Galileo outside of a product.

The RC12
The RC12The RC12
The RC12 is an Intermec designed radio platform incorporating the MuRata WLAN/Bluetooth radio module
LBEH1Z9PFC-TEMP.
Please see reference section for data sheet. This device is a dual function IEEE 802.11 bgn
transceiver, a Bluetooth 2.1 compliant radio transceiver. The module contains independent transceivers for each radio
technology; IEEE 802.11 and Bluetooth. This variants system is capable of operating at the 2.4 GHz for the IEEE 802.11
transceiver, or 2.4 GHz band for the Bluetooth transceiver.
The MuRata MODULE is based on the following 802.11 and Bluetooth chipsets from Texas Instruments;
WL1273 Single-Chip MAC baseband processor and RF transceiver supporting 802.11 b/g/n standard
The RC12
The RC12The RC12
The RC12 and subsequent variants will be manufactured by Contract manufacturer. Intermec is responsible for ensuring
proper manufacturing test of the current and future designs.
2.1 IEEE802.11 transceiver description
The IEEE 802.11 transceiver is based on the Texas Instruments WL1273 single-chip IEEE 802.11bgn MAC, Baseband, and
Direct Conversion transceiver. This system functions to provide wireless LAN connectivity supporting data rates from 1
Mbps to 54 Mbps and MCS0 to MCS7 in the 2.4-GHz band. The Triquint
TQP6M9002
provides RF frontend capabilities
for the 2.4 GHz. This variant only allows the 2.4 GHz transceiver to be in operation.
The Texas Instruments WL1273 employs a 4-Wire SDIO system bus interface to the HOST.
The PLATFORM uses a single antenna port for the 2.4 GHz of the IEEE transceivers.
The system provides a typical power output in the 2.4 GHz band of 17.5 dBm.
The 2.4 GHz transceiver supports data rates of 1, 2, 5.5 and 11 Mbps using CCK/DSSS and 6, 9, 12, 18, 24, 36, 48 and 54
Mbps using OFDM as per IEEE802.11-2007. Data rates MCS0 to MCS7 conform to amendment IEEE802.11n-2009.
The system is designed to only use the 20 MHz occupied BW capacity. Data rates MCS0 to MCS7 conform to amendment
IEEE802.11n-2009.
Data transmission from the IEEE transceiver is initiated by the IEEE 802.11 compliant MAC software. The source of data
to transmit can either be user supplied data (from the host systems) or network control packets (ACK’s CTS, PSPoll,
ProbeRequest etc). The transmitter is only active during the transmission of one of the packets previously mentioned.
2.2 Bluetooth transceiver description
The Bluetooth subsystem is built on the Texas Instruments BRF6450 ; a single-chip CMOS, Bluetooth® 2.1-compliant,
Enhanced Data Rate (EDR) capable, stand-alone baseband processor with an integrated 2.4-GHz transceiver. The BRF6450
transceiver uses the Bluetooth SIG standard Host Controller Interface (HCI) via 4-Wire HighSpeed UART and PCM audio
interfaces. The BRF6450 incorporates all Bluetooth 2.1 features including eSCO, AFH, and support for collaborative
coexistence with WLAN devices.
The Bluetooth transceiver uses a single independent antenna that is common with the IEEE Transceiver.
The Bluetooth transceiver is built with a Bluetooth Class 1.5 specification RF output power (approx +6 dBm, for an approx
50meter range).
The Bluetooth transceiver uses Bluetooth compliant frequency hopping spread spectrum to cover 79 channels 1 MHz wide
from 2.402 GHz to 2.481 GHz.
The Bluetooth transceiver supports Bluetooth Basic data rates of 1 Mbps (GFSK) as well as Enhanced Data Rates of 2 Mbps
(π/4-DQPSK) and 3 Mbps (8-DPSK)
Data transmission from the Bluetooth transceiver is controlled by software in the baseband processor.
2.3 Simultaneous operation
Simultaneous operation of the WL1273 and BRF6450 transmitters is not possible when WiFi is operating on 802.11bgn (2.4
GHz). While in operation, coexistence is always enabled. This arbitrates packets so that WiFi and Bluetooth packets
are alternately transmitted. That is the transmissions are time division multiplexed.
The test tool does not allow simultaneous transmitter operation of 802.11bgn or 802.11an and Bluetooth.
3 System Level Requirements
The following is a summary list of MODULE baseline requirements that are detailed in subsequent clauses. This reflects
the current 802.11 bgn implementation and will change to reflect any future updates such as 802.11n.
