comparison of CDMA, TDMA,OFDM,CDMA-2000, SSMA,WCDMA Smt. Indira Gandhi College of Engineering, Navi Mumbai, Mumbai
This document provides a comparison table of various mobile communication technologies including FDMA, TDMA, W-CDMA, CDMA-IS-95, CDMA-IS-2000, OFDM, SSMA, and SDMA. The table compares these technologies across parameters such as features, technology, generation, encoding, year of first use, roaming capabilities, interference levels, signal quality, frequency utilization, call density, handoff types, and ability to perform voice and data communications simultaneously. SSMA is described as a tool to automate database migration from databases like Microsoft Access, DB2, MySQL, Oracle and Sybase to Microsoft SQL Server.Cdma Vs Gsm1
CDMA and GSM are two competing digital mobile communication technologies. GSM was developed first in 1982 to standardize cellular networks across Europe. It uses TDMA to allow multiple users to access the same radio frequency at different times. CDMA was developed later and uses spread spectrum technology to allow multiple users to access the same radio frequency simultaneously through the use of unique codes. While CDMA provided benefits like increased capacity and security, GSM became the more widely adopted standard globally due to its early start and ability to provide international roaming. Today the difference between the two technologies has blurred as carriers support both.
GSM & CDMA
GSM and CDMA are the two main cellular technologies. GSM, or Global System for Mobile Communications, uses frequency division multiple access and has over 90% market share globally. CDMA, or Code Division Multiple Access, was originally developed for the Soviet military in 1935 and uses compulsory encryption and a single transmission channel by assigning codes to each signal. Both technologies underlie modern 2G and 3G cellular networks.
Cdma ppt for ECE
CDMA is a digital cellular technology that allows multiple users to access a single radio channel simultaneously through the use of unique code assignments. The document discusses CDMA network architecture, which includes mobile stations, base stations, base station controllers, mobile switching centers, home and visitor location registers, and authentication centers. It also compares CDMA to earlier multiple access technologies like TDMA and FDMA, noting advantages of CDMA like increased capacity and soft handoffs between cells using the same frequency.
Gsm&cdma
There are two main cellular network technologies: GSM and CDMA. GSM carriers include Cingular Wireless, T-Mobile, and others, while CDMA carriers include Sprint PCS and Verizon. Understanding the differences between GSM and CDMA, such as coverage, data speeds, roaming capabilities, and use of SIM cards, can help a customer choose the preferable network for their needs. While CDMA was initially faster, both technologies continue advancing and neither is clearly superior.
GSM vs CDMA
This document compares GSM and CDMA mobile technologies. It outlines that GSM uses TDMA and FDMA to allow multiple users to access frequencies, while CDMA uses direct sequence spread spectrum and unique codes to separate users on the same frequency. The document discusses features of each technology such as frequency reuse in GSM. It analyzes advantages of both such as better voice quality in CDMA due to use of entire spectrum, and international roaming capability in GSM. Overall, the document provides a technical overview comparing key aspects of GSM and CDMA mobile networks.
CDMA TECHNOLOGY
CDMA is a method for implementing a multiple access communication system that allows many subscribers to share the same communication channel simultaneously. It overcomes drawbacks of previous methods like FDMA and TDMA by spreading users across both frequency and time in the same channel. Key advantages of CDMA include increased capacity, no need for frequency management, better performance for micro-cell and in-building systems, lower transmitted power needs, and reduced infrastructure requirements. While it faces challenges from multi-user interference and multi-path fading, CDMA has gained widespread acceptance due to dramatically increasing network capacity and service quality while providing more secure communications.
3G Basic Overview
3G is defined by the ITU and called IMT-2000. It evolved from 2G technologies through intermediary 2.5G and 3.5G standards. UMTS is the 3G standard developed by 3GPP as an upgrade from GSM, using W-CDMA technology. UMTS network architecture consists of the core network, UTRAN radio access network, and user equipment. The UTRAN air interface uses W-CDMA technology with Node-B base stations controlled by RNCs. 3.5G technologies like HSPA extend UMTS with features like adaptive modulation and fast scheduling to enhance performance.

Mobile communication - GSM/CDMA/WIMAX Technologies
Mobile communication allows communication without a physical connection and flexibility to move anywhere during communication. It uses technologies like GSM and CDMA. Mobile communication has become one of the fastest growing industries. A mobile handset allows making and receiving calls over radio links while moving. It contains components like a battery, SIM card and antenna. A SIM card identifies the subscriber to the network. In mobile communication, a cell is the smallest area, subscribers pay for use, and base stations connect mobile units to switching centers. As users move, handoffs transfer calls between base stations to maintain connectivity.

AN003 RF MEMS System Level Considerations for Optimized Battery Life
This document discusses how RF MEMS switches can improve battery life in LTE mobile handsets. It begins by explaining that the power amplifier is a major source of power consumption and its efficiency, defined by PAE, affects battery life. Higher insertion losses in the RF front-end lower PAE by requiring more output power. LTE networks typically use high output powers for short bursts, resulting in much shorter battery life compared to 3G. Applying RF MEMS switches can minimize insertion losses and improve PAE, enhancing efficiency and extending battery life for LTE technology.
