http://ec.europa.eu/enterprise/newapproach/standardization/harmstds/reflist.html
Host Label Requirement
A readily visible label is required on the outside of the host that state i.e. “FCC ID:
IHDT56DB2/IC ID: 109O-DB2 is contained within”, provided the host is within the limits of the
module grant. You must not remove the label from embedded module.
FCC Notice to Users
Motorola has not approved any changes or modifications to this device by the user. Any changes
or modifications could void the user's authority to operate the equipment. See 47 CFR Sec. 15.21.
viii Module Hardware Description May 31, 2008
Preface
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. See 47 CFR
Sec. 15.19(3).
If your mobile device or accessory has a USB connector, or is otherwise considered a computer
peripheral device whereby it can be connected to a computer for purposes of transferring data,
then it is considered a Class B device and the following statement applies:
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 the receiver.
• Connect the equipment to 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.
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.
2. This device must accept any interference received, including interference that may cause

precautionary measures in order to avoid ESD while handling the module. ESD can damage the
W24/G24 modules. Integrators need to design ESD protection on all external interfaces.
Antenna and Transmission Safety Precautions
User Operation
Do not operate your unit when a person is within eight inches (20 centimeters) of the antenna. A
person or object within 8 inches (20 centimeters) of the antenna could impair call quality and may
cause the unit to operate at a higher power level than necessary, as well as expose that person to
RF energy in excess of that established by the FCC RF Exposure Guidelines.
May 31, 2008 Module Hardware Description ix
Standards
Important: The unit must be installed in a manner that provides a minimum separation distance
of 8 inches (20 centimeters) or more between the antenna and persons and must not
be co-located or operate in conjunction with any other antenna or transmitter in
order to satisfy FCC RF exposure requirements for mobile transmitting devices.
Important: To comply with the FCC RF exposure limits and to satisfy the categorical exclusion
requirements for mobile transmitters, the requirements described in the following
section, “Antenna Installation” , must be met.
Antenna Installation
• A minimum separation distance of 8 inches (20 centimeters) must be maintained between the
antenna and all persons.
• When using G24 module: The combined cable loss and antenna gain must not exceed +7.5
dBi (850MHz band). The combined cable loss and antenna gain must not exceed +2.5 dBi
and total system output must not exceed 2.0W EIRP in the PCS (1900) band in order to
comply with the EIRP limit of 24.232 (b). OEM installers must be provided with antenna
installation instruction and transmitter operating conditions for satisfying RF exposure
compliance.
• When using W24 module for meeting FCC - the combined cable loss and antenna gain must
not exceed 6 dBi (2400 MHz Band) and the total system output must not exceed 1.0W peak
output power 15.247(b) Or/and for meeting the EN 300 328 standard - Maximum EIRP
spectral density 10 dBm/MHz. The combined cable loss and antenna gain must not exceed
3dBi.
Standards
Section 15.203 - Antenna Requirement
An intentional radiator shall be designed to ensure that no antenna other than that furnished by the
responsible party shall be used with the device. The use of a permanently attached antenna or of
an antenna that uses a unique coupling to the intentional radiator shall be considered sufficient to
comply with the provisions of this Section. The manufacturer may design the unit so that a
broken antenna can be replaced by the user, but the use of a standard antenna jack or electrical
connector is prohibited. This requirement does not apply to carrier current devices or to devices
operated under the provisions of Sections 15.211, 15.213, 15.217, 15.219, or 15.221. Further, this
requirement does not apply to intentional radiators that must be professionally installed, such as
perimeter protection systems and some field disturbance sensors, or to other intentional radiators
which, in accordance with Section 15.31(d), must be measured at the installation site. However,
the installer shall be responsible for ensuring that the proper antenna is employed so that the
limits in this Part are not exceeded.

Chapter 1: Introduction
W24 is a self contained Wi-Fi module, supporting IEEE 802.11b/g systems in 2.4GHz band. W24
enables IP connectivity to any host device. It is ideal for enabling M2M applications to achieve
secure, high speed throughput and access to IP networks via 802.11b/g wireless LANs or even via
Cellular network when connected to G24 GSM/GPRS module family.
W24 integrates an operating system, drivers and communication stack, wide assortment of
proven security protocols, NATs for management purposes, built-in web server for managing the
device via web and inherent built-in device firewall.
Operation Setup
The W24 supports two operating setup configurations:
• Stand Alone configuration
• Stacked assembly configuration (with G24).
Stand Alone Configuration
Stand Alone configuration consists of a W24 as a stand alone Wi-Fi module that is controlled by
the host.
In this configuration, the W24 70 pin host connector (bottom connector) is used for interfacing
with the W24.
Figure 1-1 below illustrates the W24 Stand Alone configuration.
Figure 1-1: W24 Stand Alone Configu ration
Stacked Configuration
Stacked configuration consists of a G24 that is mounted on top of the W24 in a piggy-back
configuration. In this configuration, the W24 70-pin host connector (bottom connector) is used
for interfacing with the host board, while the G24 is connected to the W24 cellular 70-pin
interface connector (top connector).
