2. Hardware
2.1 Hardware Environment
2.1.1 Introduction
LA-5127 CF card can be used in handheld mobile devices to provide wireless
network access. LA-5127 communicates using Radio Frequencies (RF) between
two or more users or between a user and the wired network. The module
implements the IEEE802.11g physical (RF) specification. The chipset used
provides for modulation, demodulation, spreading and despreading of the RF
signals.
2.1.2 Card Dimensions
LA-5127 is a modified type I CFA card. See Appendix 2 for Mechanical Interface
Drawing.

2.1.4 Electrical Interface
The electrical interface for LA-5127 is PC16. The chipset used supports this
interface; therefore no external component is required. The host must support the
PC16 interface as well. The card uses only the 16-bit interface.

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.
The OEM integrator must NOT provide information in the user guide of the
end product regarding how to install or remove this RF module.

3.1 Final Product Compliance
The model numbers used for Regulatory Approvals are:
LA-5127C2 (connector version)
LA-5127A2 (antenna version)
The LA-5127 has been regulatory approved for OEM 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
3. The ‘Type’ and ‘Gain’ of the antenna selected for the integration of the
external antenna must meet the requirements as detailed in section 3.2.
Used outside of these conditions will trigger re-approval. Symbol advises the use
of an accredited test laboratory for advice. Be prepared, the certification process
for your product may take from a few weeks to several months.

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 (applicable to connector version card)
A reference antenna has been used during the approval process for the
connector version radio card.
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.
Note: The Adapter cable must be considered as it is part of the system gain.
Use of an alternative antenna, different ‘type’ or same ‘type’ but higher gain will
invalidate the country approvals. Under this instant the OEM integrator is
responsible for re-evaluating the end product and obtaining separate approvals.
