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.

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
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.

Operation
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.
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!
