1. Introduction
1.1 Background
21-92955 is the next generation SDIO radio module for Symbol embedded
solutions and is intended for handheld applications.
1.2 Purpose
The purpose of this document is to define the functional characteristics (electrical,
mechanical) of the module and provide regulatory information helpful to the
product teams to integrate or embed the module in a variety of systems. A
section outlining Good Design Practices is also incorporated to help with the
overall integration of the device.

1.4 Key Features and Standards supported
The module supports all required modes of operation as an 802.11g and 802.11a
Mobile Unit (MU). In 802.11g mode, the radio supports three different modulation
modes: Legacy 1 and 2Mbps, Complimentary Code Keying (CCK), and
Orthogonal Frequency Division Multiplexing (OFDM). The radio supports the
following 12 data rates in 802.11b/g mode:
Data Rate (Mbps) Modulation
1 DBPSK
2 DQPSK
5.5 CCK
6 OFDM with BPSK Carrier Modulation
9 OFDM with BPSK Carrier Modulation
11 CCK
12 OFDM with QPSK Carrier Modulation
18 OFDM with QPSK Carrier Modulation
24 OFDM with 16QAM Carrier Modulation
36 OFDM with 16QAM Carrier Modulation

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.
