3 CDMA Overview
The first CDMA networks (now called CDMAone) were commercially launched in 1995, and
provided roughly 10 times more capacity than analog networks - far more than TDMA or GSM.
Since then, CDMA has become the fastest-growing of all wireless technologies. In addition to
supporting more traffic, CDMA brings many other benefits to carriers and consumers, including
broader coverage and stronger security.
Just as the second generation of wireless technology improved upon earlier systems, the industry
looked to a third generation of technology for more advances. Although wireless was used
almost exclusively for voice communication, the ability to deliver data over the air was also very
promising, especially as Internet users and content proliferated.
In 1999, the International Telecommunication Union adopted an industry standard for thirdgeneration (3G) wireless systems that can deliver high-speed data and other new features.
Because CDMA2000 is evolved directly from the previous generation of proven CDMA
systems, it provides the fastest, easiest, most cost-effective path to 3G services. While all 3G
technologies (CDMA2000, WCDMA and TD-SCDMA) may be viable, CDMA2000 is much
further ahead in terms of product development, commercial deployment and market acceptance.
The first commercial CDMA2000 networks were launched in South Korea in early 2001. A large
and growing range of CDMA2000 chipsets, terminals and network infrastructure systems are
now in volume production and gaining economies of scale, as many more North American,
Latin American and Japanese carriers plan to roll out CDMA2000 services in 2002 and 2003
CDMA2000 1X technology supports both voice and data services over a standard (1X) CDMA
channel, and provides many performance advantages over other technologies. First, it provides
up to twice the capacity of earlier CDMA systems, helping to accommodate the continuing
growth of voice services as well as new wireless Internet services. Second, it provides peak data
rates of up to 153 kbps (and up to 307 kbps in the future), without sacrificing voice capacity for
data capabilities. And because it's backwards-compatible with earlier CDMA technology,
CDMA2000 1X provides an easy and affordable upgrade path for both carriers and consumers.
For more information about CDMA visit the CDMA Development Group (CDG) at
http://cdg.org/ The CDG is an industry consortium of companies who have come together to
develop the products and services necessary to lead the adoption of CDMA wireless systems
around the world.
4 GPS Overview
The Global Positioning System (GPS) is a worldwide radio-navigation system operated by the
US Department of Defence (DoD) and formed from a constellation of 24 satellites orbiting at
an altitude of 10,900 nautical miles and with an orbital period of 12 hours.
Page 5
CTM-110/120 Installation & Operation Manual
1702-0037 Rev 3.2
GPS uses these satellites as reference points to calculate positions accurate to a matter of metres.
This is achieved by measuring the time it takes for a radio signal to travel from each satellite to
the receive unit. Multiple measurements are then used to accurately triangulate the receiver
location.
The signals received from the orbiting satellites are based on pseudo random codes. The code
for each satellite is unique so that the receiver can determine which satellite it is receiving from.
Additionally, these pseudo random codes are extremely complex in order to minimize the
possibility of incorrectly picking up another signal or background noise with the same code. The
receiver is able to generate the same pseudo random code for every satellite it is tracking. The
difference in time between the locally generated code and the code received from the satellite is
used to calculate the distance from the satellite to the receiver. The receiver keeps track of the
exact location of every satellite by using an almanac stored in its local memory. In this way the
receiver is able to triangulate its location by calculating the distance from at least three satellites.
But this calculation assumes that the receiver generates its pseudo random code starting at
exactly the same time as the satellites, which would require extremely accurate (and expensive)
atomic clocks in every receiver! The receiver overcomes the need for such an accurate clock by
triangulating its position from at least four satellites instead of only three. The additional satellite
allows the receiver to calculate its own clock error and to apply this correction to all calculated
distances.
There are a number of error sources that can introduce inaccuracies into the position calculation.
Understanding these error sources can be helpful in applying the position information provided
by the GPS receiver.
• Although the satellites are in extremely accurate orbits they can be influenced by solar
“winds” of cosmic radiation and also by gravitational forces from the sun and moon. These
errors are called "ephemeris” errors". The satellites position is regularly monitored by the US
DoD and then passed to the satellite for passing on to the receivers as part of the pseudo
random code information. The receiver is then able to account for these ephemeris errors.
However, between these position updates there may be a slight error in the calculated signal.
• As a GPS signal passes through the charged particles of the ionosphere and then through the
water vapour in the troposphere it gets slowed down, and this creates a timing measurement
error which may be different for each satellite and so cannot be taken into account.
• Close to the ground the signal may bounce off various local obstructions before it reaches
the receiver. This is called multipath error and is similar to the ghosting on a TV.
• There are often more satellites available than a receiver needs to fix a position, so it will
choose a few and ignore the rest. If it chooses satellites that are close together in the sky the
intersecting circles that define a position will cross at very shallow angles. This increases the
grey area or error margin around a position. If it chooses satellites that are widely separated
then the circles intersect at almost right angles which minimizes the error region.
In general, all the above error sources combined may result in a position error of only a few
metres overall.

8 Operation
8.1 Automatic power control
The CTM-110 Chameleon modem has a low power mode that shuts down all
unnecessary circuits when the modem is not in use but will automatically power up when
it detects user action.
The supply voltage must be at least 8VDC for the CTM-110 to operate. Below this level
the modem will enter low power standby mode.
Operation mode is entered when the modem detects that the RS232 port is active (DTR
going active is used for this)
AND
the standby signal is greater than 9VDC.
With these two conditions met the CTM-110 modem will enter operating mode in 10
seconds. In operating mode the power LED will be on solid.
Standby mode is entered when the modem detects that the RS232 port is inactive (DTR
going inactive is used for this)
AND
the standby signal is less than 9VDC (connected to 0V or disconnected).
With these two conditions met the CTM-110 modem will enter standby mode in 5
seconds. In standby mode the power LED will flash slowly.
8.2 Manual power control
The CTM110 modem can be manually put into low power standby mode at any time by
pressing and holding for at least one second the standby button which is located inside the
front panel (use a straightened paper clip to access it through the hole).
Pressing and holding the standby button when the CTM-110 modem is in low power
standby mode will put it into operating mode – but note that if either the RS232 port is
inactive OR the standby signal is less than 9VDC, then the CTM-110 will automatically
enter low power standby mode again after 5 seconds!

The local GPS reporting may be enabled
either for this session only or for this and
all future sessions. The GPS update rate
may be set to a value from once per
second, to once per 3600 seconds. GPS
data is sent as a UDP packet to port 5005
of the local host PC. The Chameleon
Controller Software application provides
an automatic utility which makes this data
available on a virtual COM port in the
computer which may be accessed by
standard mapping software applications.
When the remote connection is enabled it must have a remote IP address and port number
configured. This will be the remote server that will accept this GPS data and allow tracking of
the vehicle or equipment in which the modem is installed. The GPS update rate may be set to a
value from once per second, to once per 3600 seconds.

modems. This command set can be used to configure, control, and troubleshoot the
modem.
The Chameleon Controller Software Terminal tool may be used to send AT commands
to the modem and display responses. Alternatively, most terminal emulation programs
such as Windows HyperTerminal can be used to access the CTM-110/120 with AT
commands. Terminal configuration parameters are:
Data rate 115,200 baud
Data bits 8
Parity None
Stop bits 1
Flow control Hardware
The set of AT commands available for the CTM-110/120 CDMA modem can be found
in the Sierra Wireless CDMA AT command reference document available at:

9 Trouble shooting
Situation The power LED is flashing slowly and I can’t communicate with the
modem.
Solution: The modem is in low power standby mode. Make sure that the standby
signal is connected to greater than 9VDC AND the RS232 port is active.
Situation: The USB to serial converter isn’t working.
Solution: Make sure that the CTM-110/120 modem has been installed in Windows
to use the same comms. port as that used by the USB to serial converter.
Situation: DUN makes a connection but no Internet applications work.
Solution: Make sure that any firewall clients running on your computer have been
disabled (especially if you use your computer in an office LAN
environment).
Situation: How do I check to see if my modem is registered on the network?
Solution: Use the Chameleon Controller software and from the Tools menu select
Modem Status. This provides the following information:
Current band (PCS or CDMA)
Current channel
SID
NID
Modem temperature in degrees Celsius
Pilot acquired (or not)
Modem registered (or not)
Alternatively, from the Tools menu select Terminal and enter the
command AT!STATUS
Situation: I need to find the ESN of the modem but I can’t access the label on its
base.
Solution: Use the Chameleon Controller software and from the Tools menu select
Modem Status. This will return the modems ESN in an 11 digit decimal
format.
Alternatively, from the Tools menu select Terminal and enter the
command AT+GSN. This will return the modems ESN in an 8 digit
hexadecimal format. Convert this to decimal format by separating the
hex number into two parts prior to performing the conversion:
hh-hhhhhh

Situation: How do I find out the CDMA signal strength seen by the modem.
Solution: Use the Chameleon Controller software and from the Tools menu select
Modem Status. This will return information including the current
received signal strength in dBm as seen by the modem:
-137 = no signal!
<-90 = very poor
-90 to -86 = poor
-85 to -81 = fair
-80 to -76 = good
>-75 = excellent
Alternatively, from the Tools menu select Terminal and enter the
command AT!RSSI?. This will report the current received signal strength
in dBm
