2-2 LA-5137 Compact Flash Adapter Integration Guide
2.2 Hardware Environment
2.2.1 Introduction
The LA-5137 CF card can be used in handheld mobile devices to provide wireless network access. It
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/g physical (RF) specification. The chipset used provides
for modulation, demodulation, spreading, and despreading of the RF signals.
2.2.2 Card Dimensions
The LA-5137 is a modified type 1 CFA card. See
Mechanical Interface Drawing.
2.2.3 Card Physical
2.2.3.1 Operational Environment
NOTE: The product is not required to be powered during test activities. Only parameters marked by an *
shall be powered during testing. Testing per Symbol Qualification Test Standard SS-03800-74.

• Altitude to withstand 15,000 feet
2.2.4 Antenna Connectors (non embedded antenna)
The LA-5137-1002-WWR CF card (External Antenna Version) supports 2 RF connector (Hirose U.FL-R-SMT, or
equivalent). The antennas can be attached to the card through the connectors. There are two connectors on
the LA-5137-1002-WWR unit.
