| Simplex |
| 2008-07-09 22:36:00 |
Simplex is one of the forms of communication of between both sides, where signal sent one way. This transmission method differs from the method full-duplex capable to send the signal and accept at the same time in one time, or half-duplexes capable to send the signal and accept the signal even do not in one time. Transmission by simplex is happened in some communications technology, like telecast or radio broadcast. Transmission Simplex is not used in network communications because nodes in network generally require the communications in two directions. It is true, some communications in network, like video streaming, seen like simplex, but in fact communications traffic happened in two direction, more than anything else if protocol TCP which is used as protocol of coat transport....

Duplex is a term in the field of telecommunications which refer to communications two directions.There are two method duplexing, namely:• Full-duplex• Half-duplexFull-duplexIn communications full-duplex, two side which communicating each other will deliver the information and accept the same information during, and generally require two communications bandCommunications Full-Duplex also can be reached for by using technique multiplexing, where signal which walk with the different direction will be put down time slot different. This Technique weakness this technique cut the transmission speed which possible becomes half.Half-duplexRepresent a communications mode where data earn the transmission or accepted in two directions but cannot by together....

At the moment there is two branch from development 3G, that is from side GSM (Global System For Mobile Communication) pioneered by 3G Partnership Project and CDMA (Code Division Multiple Access) pioneered by 3G Partnership Project 2 ( 3GPP2). Both technology do not compatible and have competition.One of the reason why service 3G can give the throughput larger ones is because technological usage spectrum spread over conducive input data which transmission will disseminated in all frequency spectrum. Besides getting broad band larger ones, service base on the spectrum spread over much more peaceful than timeslot or frequency slot.Network 3G not represent to upgrade from 2G; operator 2G which affiliate by 3GPP needing to change many components to be able ...

There is even also technological growth of nirkabel can be embraced as follows:1. First generation: analogous, low-speed, last for voice. Follow the Example Of The: NMT (Nordic Mobile Telephone) and AMPS (Analogous of Mobile Phone System)2. Second Generation: digital, low-speed - middle. Follow the example of the: GSM and CDMA2000 1xRTT.3. Third generation: digital, high-speed, for the broad band. Follow the example of the: W-CDMA (or recognized also by UMTS) and CDMA2000 1xEV-DO.Between second generation and third generation, often inserted by Generation 2,5, that is digital, middle speed (till 150 Kbps).

1. Antenna BTS for the GSM OF and CDMA usually in form of length in it there are two function antenna as transmitter and receiver. Long from antenna depended from its frequency, ever greater frequency of dimension antenna smaller conversely (from principle of pattern antenna = 1/2 lambda). BTS Antenna in general there is two types: OMNI Antenna and PANEL antenna.At antenna Microwave (MW) Radio, like drum, this is including type of high performance antenna. Usually there is 2 brand, that is Andrew and RFS. Individuality from this antenna high performance is for which is like drum, and there are its cover, so-called radome. Function Radome for example to protect the component antenna, from weather change. 2. Connection from BTS to that BSC usually use the MW radio, because usually on...

In CDMA, technique of data transmission conducted differs from the transmission at GSM. CDMA use the more peaceful transmission technique, because in this technological history early its beginning used for military.CDMA is true promise the data security if compared to an other technology like GSM, although we cannot say that the technology GSM is not peaceful. CDMA give the unique PIN code to every its user and only its user couple owning same key for the fox of code data accepted.In general, process the data transmission in explainable technology CDMA as follows.

Converse the GSM technology is not exclusive about costlier expense compared to operator CDMA; we still can trace the emulation between operators which later become madness.We can see the emulation between 3 biggest GSM operator in Indonesia which more and more the madness. Two big operator battle the price where as operator which is one do not want to follow the current and chosen the strategy by self. So draw to careful.If seen from usage of frequency band and technological, hence there is again war to be happened, but in this case old operator very beneficial with the existence of frequency of dual band which they have the.
