1. Section1:

1.1 Summary:

RMWIFI-M3 based on RMWIFI-M5 module provides a quick, easy and cost

effective way to add Wi-Fi capabilities for RAE Systems products, such as

AreaRAE2, MutlRAE2, and RAE-Hub etc.

The module combined 802.11 MAC, security, PHY functions, FLASH SRAM, and

external antenna connectors, provides a Wi-Fi radio for end customers. It also

integrates TCP/IP stack and other related network stacks such as DHCP client,

DHCP server and web server etc. It can be used to connect to Ethernet

conveniently and transfer data to network server like ProRAE Guardian directly.

1.2 Key Features:

• 46 * 26 mm (Length * Width) with M3 40-PINs interface

• RCS protocol API for application interface

• DSSS modulation for 1and 2Mbps, CCK modulation for 5.5 and 11Mbps

• Compatible with IEEE 802.11 b

• UART interface, SPI interface, I2C interface, one ADC channel, several GPIOs

• Low power consumption

• RoHS compliant, certified lead- and halogen-free

2. Section2:

2.1 Overview:

RMWIFI-M3 operates in the unlicensed 2.4 radio bands IEEE 802.11b, which

supports Direct Sequence Spread Spectrum (DSSS) 1 Mb/s and 2 Mb/s data

rates, and Complementary Code Keyed (CCK) 5.5 Mb/s and 11 Mb/s data rates.

RMWIFI-M3 is based on RMWIFI-M5 module, which contains GS1011 WIFI

RAE Systems by Honeywell

Honeywell Confidential and Proprietary Revision –1.0 Page 5 of 29

system-on-chip. The GS1011 have fully integrated RF Transceiver, low power

PA and application processor. Both TX and RX chain in the module incorporate

internal power control loops.

RMWIFI-M3 carries onboard single supply monitor for 1.8V voltage supply with

optional module controlled external regulator enable control pin (DC_DC_CNTL).

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two

conditions: (1) this device may not cause harmful interference, and (2) this device must accept

any interference received, including interference that may cause undesired operation.

Changes or modifications not expressly approved by the party responsible for compliance could

void the user's authority to operate the equipment.

This equipment has been tested and found to comply with the limits for a Class B digital device,

pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection

against harmful interference in a residential installation. This equipment generates uses and can

radiate radio frequency energy and, if not installed and used in accordance with the instructions,

may cause harmful interference to radio communications. However, there is no guarantee that

interference will not occur in a particular installation. If this equipment does cause harmful

interference to radio or television reception, which can be determined by turning the equipment

off and on, the user is encouraged to try to correct the interference by one or more of the

following measures:

-Reorient or relocate the receiving antenna.

-Increase the separation between the equipment and receiver.

-Connect the equipment into an outlet on a circuit different from that to which the receiver is

connected.

-Consult the dealer or an experienced radio/TV technician for help.

MPE Reminding

To satisfy FCC RF exposure requirements, a separation distance of 20 cm or more should be

maintained between the antenna of this device and persons during device operation. To ensure

compliance, operations at closer than this distance is not recommended.

Region Selection

Limited by local law regulations, version for North America does not have region selection option.

Information for the OEM Integrators

This device is intended for OEM integrators only. Please see the full grant of equipment

document for restrictions.

Label Information to the End User by the OEM or Integrators

If the FCC ID of this module is not visible when it is installed inside another device, then the

outside of the device into which the module is into which the module is installed must be label

with "Contains FCC ID: SU3RMWIFI".
