What does cdma phones mean? Report Abuse. Code division multiple access (CDMA) is a channel access method utilized by various radio communication technologies. It should not be confused with the mobile phone standards called cdmaOne and CDMA2000 (which are often referred to as simply CDMA), this uses CDMA as an underlying channel access method.elevance. Rating Newest Oldest. Best Answer: it is when the cell company has the information for the network stored in the phone its self like sprint, alltel, verizon. Gsm is where you have a sim card in the phone and the sim card store all the information for the network like AT&T, TMobile..

Carrier-sense multiple access with collision detection Carrier-sense multiple access with collision detection (CSMA/CD) is a media access control method used most notably in early Ethernet technology for local area networking. It uses a carrier-sensing scheme in which a transmitting station detects collisions by sensing transmissions from other stations while transmitting a frame.

CDMA vs. GSM: What's the Difference? If you're shopping for a mobile phone, you're in for a lot of acronyms. Here's what you need to know about two basic, yet important, terms. Two basic technologies in mobile phones, CDMA and GSM represent a gap you can't cross. They're the reason you can't use many AT&T phones on Verizon's network and vice versa.hat CDMA vs. GSM Means to You For call quality, the technology you use is much less important than the way your carrier has built its network. There are good and bad CDMA and GSM networks, but there are key differences between the technologies. Here's what you, as a consumer, need to know.

GSM (Global System for Mobile communication) GSM (Global System for Mobile communication) GSM (Global System for Mobile communication) is a digital mobile telephony system that is widely used in Europe and other parts of the world. GSM uses a variation of time division multiple access (TDMA) and is the most widely used of the three digital wireless telephony technologies (TDMA, GSM, and CDMA). GSM digitizes and compresses data, then sends it down a channel with two other streams of user data, each in its own time slot.

- Fig. 1 Simplified downlink structure of a CDMA-based cellular system including an inter-mobile interleaving. The inter-mobile interleaving is a simple process to exchange the symbol-level processing outputs in order for the data to be alternatively transmitted through downlink channels for mobiles in the same cluster. Let’s define the symbol-level

Tutorial on agent-based modelling and simulation Agent-based modelling and simulation (ABMS) is a relatively new approach to modelling systems composed of autonomous, interacting agents. Agent-based modelling is a way to model the dynamics of complex systems and complex adaptive systems. Such systems often self-organize themselves and create emergent order.

"What is ""GSM""?" What is GSM? GSM is a TDMA based wireless network technology developed in Europe that is used throughout most of the world. GSM phones make use of a SIM card to identify the user's account. The use of the SIM card allows GSM network users to quickly move their phone number from one GSM phone to another by simply moving the SIM card. Currently GSM networks operate on the 850MHz, 900MHz, 1800MHz, and 1900MHz frequency bands.

SDMA - patial division multiple access Short for spatial division multiple access, SDMA is a satellite communications mode for using data from antenna arrays in wireless communications systems. At the base station, SDMA continually adapts to the radio environment, providing each user with uplink and downlink signals of the highest possible quality. At the network level, this improved base station performance can be exploited to increase base station range. [Adapted from 'Intelligent Antennas: Spatial Division Multiple Access']
