CDPD TECHNOLOGY



INTRODUCTION


Mobile Computing: A technology that allows transmission of data, via a computer, without having to be connected to a fixed physical link.

Principle of Mobile Computing: The ability to send and receive data across the cellular networks.

First Generation

Analog Signal Communication
Advanced Mobile Phone System (AMPS) by North America
Based on Frequency Division Multiple Access (FDMA)
1664 Channels were avail ....etc

CDPD is a secure, proven, and reliable protocol that has been used for several years by law enforcement, public safety, and mobile professionals to securely access critical, private information. CDPD has several features to enhance the security of the mobile end user's data and these are discussed below.

OPERATION OF CDPD

A brief overview of the operation of the CDPD network is as follows:
A wireless modem (or Mobile End System-M-ES) communicates by radio with the Mobile Data Base Station (MDBS). The MDBS transfers this data by landline ....etc

The Visual System

Introduction
The human visual system is remarkable instrument. It features two mobile acquisition units each has formidable preprocessing circuitry placed at a remote location from the central processing system (brain). Its primary task include transmitting images with a viewing angle of at least 140deg and resolution of 1 arc min over a limited capacity carrier, the million or so fibers in each optic nerve through these fibers the signals are passed to the so called higher visua ....etc

Laser Communication Systems

Introduction
Lasers have been considered for space communications since their realization in 1960. Specific advancements were needed in component performance and system engineering particularly for space qualified hardware. Advances in system architecture, data formatting and component technology over the past three decades have made laser communications in space not only viable but also an attractive approach into inter satellite page link applications.

Embryonics Approach Towards Integrated Circuits

Introduction
Embryonics is embryonic electronics. Working of multicellular organization in living beings suggests that concepts from biology can be applied to development of new embryonic integrated circuits. The final objective is the development of VLSI circuits that can partially reconstruct themselves in case of a minor fault (self-repair) or completely reconstruct the original device in case of major fault (self-replication). These features ar ....etc
