2. Hardware
2.1 Introduction
The 21-92955 module can be used in handheld mobile devices to provide
wireless network access. The module communicates using Radio Frequencies
(RF) between two or more users or between a user and the wired network. The
module implements the IEEE 802.11a and IEEE802.11g physical (RF)
specification. The chipset used provides for modulation, demodulation, spreading
and despreading of the RF signals.

2.3 Electrical Interface
The electrical interface for the module is SDIO. The chipset used supports this
interface; therefore no external component is required. The host must support the
SDIO interface as well.
3. Regulatory Product Compliance
Legal Disclaimer: This Guide may contain information on regulatory matters. The
information should be used with the understanding that Symbol is not engaged in
rendering any legal, regulatory or other professional opinion. Each country has
specific laws and regulations governing the use of radio communications. Please
consult the official code for each country of interest. Symbol does not warrant
the accuracy of the information contained herein and accepts no liability or
responsibility for any use or misuse of the information
Symbol’s wireless network devices are designed to be compliant with rules and
regulations in locations they are sold.
Any changes or modifications to Symbol Technologies equipment, not expressly
approved by Symbol Technologies, could void the user’s authority to operate the
equipment.
IMPORTANT NOTE:
End product user guide must NOT include any information regarding how
to install or remove this RF module.
3.1 Final Product Compliance
The model Number used for Regulatory Approvals is: 21-92955
The module has been regulatory approved for integrations which meet the
following conditions:
1. The radio integration is embedded
2. The antenna must be installed such that 20 cm is maintained between the
antenna and users
21-92955 Integration Guide
Copyright 2004 Symbol Technologies, Inc. Page 7 of 11
3. The ‘Type’ and ‘Gain’ of the antenna selected for the integration of the
external antenna must meet the requirements as detailed in section.
Used outside of these conditions will trigger re-approval
As the integrator, you are responsible to determine what additional specific
regulatory requirements are required of the country in which your product will be
marketed. Final product may require non-radio frequency approvals such as
Product Safety, EMC, and SAR.
3.2 Reference Antenna
A reference antenna has been used during the approval process.
Specific details of the reference antenna used for testing is detailed in the table
below.
Important Note:
Use of an antenna which is the same ‘type’ (eg. Dipole) and has a gain equal to
or less that the reference antenna can be used without recertification.
Use of an alternative antenna, different ‘type’ or same ‘type’ but higher gain will
invalidate the country approvals. Under this instant the integrator is responsible
for re-evaluating the end product and obtaining separate approvals.
Antenna Type: Dipole
Antenna Characteristics:
ML-2452-APA2-01

21-92955 Integration Guide
Copyright 2004 Symbol Technologies, Inc. Page 9 of 11
If the final product used in a manner where the antenna is closer than 20cm from
the user (portable use), the OEM is integrator is responsible for re-evaluating the
end product and obtaining a separate FCC authorization.
Symbol recommends the use of an accredited Laboratory to carry out the
necessary tasks.
3. Channels
For use in the USA the available 802.11b/g channels are limited from 1 to 11.

Radio Frequency Interference Requirements – FCC
Note: 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.
