2‐2 Network Module Driver Installation
Introduction
In this document, we introduce two ways to compile and install our Wi‐Fi driver: 1)
Using install.sh script for PC‐Linux and 2) Step by step manually. The former targets for
end users who are not familiar with Linux system, while the later for engineers who
want to port our Wi‐Fi driver onto different platforms.
2‐2‐1. Using install.sh Script for PC‐Linux
For driver compilation and installation in PC‐Linux, we provide an install.sh script to
do the duties automatically. If you want to use our Wi‐Fi solutions to access network on
PC‐Linux, you can just run install.sh script and then control Wi‐Fi with utilities such as
Network Manager. For further information about Wi‐Fi station mode, please refer to:
document/Quick_Start_Guide_for_Station_Mode.pdf.
If you want to apply our Wi‐Fi solutions on other embedded platforms, you
should read and check the following paragraphs.
2‐2‐2. Decompress the driver source tar ball
The driver source tar ball is located in the driver folder of our software package. For
example, to decompress rtl8188C_8192C_8192D_usb_linux_v3.3.0_2920.20111123.tar.gz:
root@driver/# tar zxvf rtl8188C_8192C_8192D_usb_linux_v3.3.0_2920.20111123.tar.gz2
2‐3. Selecting Chip Type with make_drv Script (for compound release)
Our driver source release has two types: 1) single release, which can build out
driver only for single chip type, and 2) compound release, which can build out drivers for
multiple chip types separately.
For compound release driver, you will see make_drv script after you decompress
the driver tar ball located in driver folder. Before compiling driver source, executing the
make_drv to select the target chip type to compile. For example:
root@rtl8188C_8192C_8192D_usb_linux_v3.3.0_2920.20111123# ./make_drv
Please select chip type(1/2):
1) RTL8192cu
2) RTL8192du
#? 1
You have selected RTL8192cu
2‐4. Compilation Settings in Makefile
2‐4.1. Adding or Selecting Target Platform
The default target platform is PC‐Linux, if you do not want to compile driver for
other platforms you can skip this section.
To add or select target platform for compilation, we provide two sections in
Makefile: 1) platform selection section and 2) platform setting section. First, you
should look at the platform selection section of Makefile:
CONFIG_PLATFORM_I386_PC = y
CONFIG_PLATFORM_ANDROID_X86 = n
CONFIG_PLATFORM_ARM_S3C2K4 = n
CONFIG_PLATFORM_ARM_PXA2XX = n
CONFIG_PLATFORM_ARM_S3C6K4 = n
CONFIG_PLATFORM_MIPS_RMI = n
CONFIG_PLATFORM_RTD2880B = n
CONFIG_PLATFORM_MIPS_AR9132 = n
CONFIG_PLATFORM_MT53XX = n
CONFIG_PLATFORM_RTK_DMP = n
The platform selection section consists of entries with ‘CONFIG_PLATFORM_’ prefix.
Only one entry is allowed to be set with value ‘y’ and others with ‘n’. The 3
‘CONFIG_PLATFORM_I386_PC’ is selected by default.
We can select an existing entry or add a new entry for your target platform. For
example, to add and select a new entry, ‘CONFIG_PLATFORM_NEW’:
CONFIG_PLATFORM_I386_PC = n
CONFIG_PLATFORM_NEW = y
Second, you should create and/or modify the corresponding entry inside platform
setting section. For example, adding the following entry in platform setting section for
‘CONFIG_PLATFORM_NEW’ we just add:
ifeq ($(CONFIG_PLATFORM_NEW), y)
EXTRA_CFLAGS += ‐DCONFIG_LITTLE_ENDIAN
ARCH := arm
CROSS_COMPILE := /opt/ new/toolchain/arm‐eabi‐4.4.3/bin/arm‐eabi‐
KSRC := /opt /new/kernel
endif
2.4.2. Platform Setting Section in Detail
EXTRA_CFLAGS
The EXTRA_CFLAGS is usually
Effect
used to carry some additional settings
at compilation time through macro
definitions. Macro
CONFIG_BIG_ENDIAN
Define some internal data structure as big
endian.
CONFIG_LITTLE_ENDIAN
Define some internal data structure as little
endian.
CONFIG_MINIMAL_MEMORY_USAGE
For better performance in powerful platform,
we allocate large physical continuous memory
as TX/RX IO buffers. In some
embedded platform, there is chance to fail to
allocate memory. Define this macro to prevent
this situation.
CONFIG_PLATFORM_ANDROID
Older Android kernel do not has
CONFIG_ANDROID defined. Define this macro
to force the Android corresponding code inside
our driver to be compiled. For newer
Android kernel, it has no need to define this
macro, otherwise, warning message about
redefinition will show up
2‐3 Glossary
1. What is the IEEE 802.11g standard?
802.11g is the new IEEE standard for high‐speed wireless
LAN communications that provides for up to 54 Mbps data rate in
the 2.4 GHz band. 802.11g is quickly becoming the next mainstream
wireless LAN technology for the home, office and public networks.
802.11g defines the use of the same OFDM modulation technique
specified in IEEE 802.11a for the 5 GHz frequency band and applies
it in the same 2.4 GHz frequency band as IEEE 802.11b. The 802.11g
standard requires backward compatibility with 802.11b.
The standard specifically calls for:
A. A new physical layer for the 802.11 Medium Access Control (MAC)
in the 2.4 GHz frequency band, known as the extended rate PHY
(ERP). The ERP adds OFDM as a mandatory new coding scheme
for 6, 12 and 24 Mbps (mandatory speeds), and 18, 36, 48 and 54
Mbps (optional speeds). The ERP includes the modulation
schemes found in 802.11b including CCK for 11 and 5.5 Mbps
and Barker code modulation for 2 and 1 Mbps.
B. A protection mechanism called RTS/CTS that governs how
802.11g devices and 802.11b devices interoperate.
2. What is the IEEE 802.11b standard?
The IEEE 802.11b Wireless LAN standard subcommittee, which
formulates the standard for the industry. The objective is to enable
wireless LAN hardware from different manufactures
to communicate.
3. What does IEEE 802.11 feature support?
The product supports the following IEEE 802.11 functions:






CSMA/CA plus Acknowledge Protocol
Multi‐Channel Roaming
Automatic Rate Selection
RTS/CTS Feature
Fragmentation
Power Management
4. What is Ad‐hoc?
An Ad‐hoc integrated wireless LAN is a group of computers, each
has a Wireless LAN module, Connected as an independent wireless
LAN. Ad hoc wireless LAN is applicable at a departmental scale for a
branch or SOHO operation.
5. What is Infrastructure?
An integrated wireless and wireless and wired LAN is called an
Infrastructure configuration. Infrastructure is applicable to
enterprise scale for wireless access to central database, or wireless
application for mobile workers.
6. What is BSS ID?
A specific Ad hoc LAN is called a Basic Service Set (BSS). Computers
in a BSS must be configured with the same BSS ID.
7. What is WEP?
WEP is Wired Equivalent Privacy, a data privacy mechanism
based on a 40 bit shared key algorithm, as described in the IEEE
802 .11 standard.
8. What is TKIP?
TKIP is a quick‐fix method to quickly overcome the inherent
weaknesses in WEP security, especially the reuse of encryption keys.
TKIP is involved in the IEEE 802.11i WLAN security standard, and the
specification might be officially released by early 2003.
9. What is AES?
AES (Advanced Encryption Standard), a chip‐based security, has
been developed to ensure the highest degree of security
and authenticity for digital information, wherever
and however communicated or stored, while making more efficient
use of hardware and/or software than previous encryption
standards. It is also included in IEEE 802.11i standard. Compare with
AES, TKIP is a temporary protocol for replacing WEP security until
manufacturers implement AES at the hardware level.
10. Can Wireless products support printer sharing?
Wireless products perform the same function as LAN products.
Therefore, Wireless products can work with Netware, Windows
2000, or other LAN operating systems to support printer or file
sharing.
11. Would the information be intercepted while transmitting on air?
WLAN features two‐fold protection in security. On the hardware
side, as with Direct Sequence Spread Spectrum technology, it has
the inherent security feature of scrambling. On the software side,
WLAN series offer the encryption function (WEP) to enhance
security and Access Control. Users can set it up depending upon
their needs.

12. What is DSSS? What is FHSS? And what are their differences?
Frequency‐hopping spread‐spectrum (FHSS) uses a
narrowband carrier that changes frequency in a pattern that is
known to both transmitter and receiver. Properly synchronized, the
net effect is to maintain a single logical channel. To an
unintended receiver, FHSS appears to be short‐duration impulse
noise. Direct‐sequence spread‐spectrum (DSSS) generates a
redundant bit pattern for each bit to be transmitted. This bit pattern
is called a chip (or chipping code). The longer the chip is, the greater
the probability that the original data can be recovered. Even if one
or more bits in the chip are damaged during transmission, statistical
techniques embedded in the radio can recover the original data
without‐the need for retransmission. To an unintended receiver,
DSSS appears as low power wideband noise and is rejected (ignored)
by most narrowband receivers.
13. What is Spread Spectrum?
Spread Spectrum technology is a wideband radio frequency
technique developed by the military for use in reliable, secure,
mission‐critical communication systems. It is designed to trade off
bandwidth efficiency for reliability, integrity, and security. In other
words, more bandwidth is consumed than in the case of
narrowband transmission, but the trade off produces a signal that is,
in effect, louder and thus easier to detect, provided that the
receiver knows the parameters of the spread‐spectrum signal being
broadcast. If a receiver is not tuned to the right frequency, a
spread –spectrum signal looks like background noise. There are two
main alternatives, Direct Sequence Spread Spectrum (DSSS)
and Frequency Hopping Spread Spectrum (FHSS).
14. What is WPS?
WPS stands for Wi‐Fi Protected Setup. It provides a simple way to
establish unencrypted or encrypted connections between
wireless clients and access point automatically. User can press a
software or hardware button to activate WPS function,
and WPS‐compatible wireless clients and access point will
establish connection by themselves. There are two types of WPS:
PBC (Push‐Button Configuration) and PIN code.
