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

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).

port 4023, remote communication node IP: 192.168.1.99, port:
6000, see following picture for detail:
8.1
Receive data packet from UDP server:
1. In order to receive data packet from remote using UDP protocol,
communication via UDP, RMWIFI will need to listen on local port:
6000.

10. Caution:
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".

For detachable antennas:
This device is tested together with a PCB and a Pole antenna. The client can use an antenna with
the same type of the two antennas, but must make sure that the maximum gain of PCB antenna
is 0dBi and the maximum gain of Pole antenna is 1.5dBi.
