Gsm Specification & Air Interface

You are an IT Network Specialist and are required to develop the design of the company’s telephone system for its new building which will begin construction in a few months. In order to get a background which will help when developing the new system, your supervisor asked you to research the current Plain Old Telephone Service (POTS) currently used by the company. You must research the system components and report back to your supervisor , the Telecommunications Manager, within a week.

Since the introduction of the first mobile phone in 1924, there has been a steady climb in developing and enhancing, the mobile phone and its supporting technologies. The cellular network infrastructures as well as service providers have been hard at work; in making sure they are providing the best service as well as devices. The infrastructure alone

The technology today is much less simple than the technology previously created. At first, the telecommunication was first brought to existence in 1947, but more important is the first mobile telephone introduced in Sweden in the 1960’s. Sweden focused on the reliance of a car through technology. So in other words, the system had been animated with the connection from a handset, which remained to be operated to forward incoming calls. As the first generation of cell phones approached, cell towers had been built all around. That is how calls had been made. Those cell phones that were in use had to be connected to a cell tower in order to be used. They called this the “Analog Cellular Networks” (Brookes). Cell phones were just strictly used for calling. Pagers had been created that just let off an audible beep to the

In recent times the world has grown to become a digital world, easily accessible and so is the use of mobile phones. The development and utilization of mobile phones has been increased over the years, Service providers have also found ways to move with this trend. The latest generation of mobile phones usually referred to as “smartphones”, are built with high technology, changing the trend of traditional method of phone communication and replacing it with modern method such as internet calling. Smartphones are now used as Still and video cameras, audio and video players, handheld gaming, the ability to surf the internet and a lot of other applications, all in the palm of your hand. A lot of service providers has been making available services that are readily and easily available to use as to keep up with the ever growing trend for example premium rate services(PRS).

The First Generation Networks were referred to as cellular networks, which later termed as cell. The cell phone signals were based on analog signal transmission, where these devices were comparatively less heavy and more cost. The Second Generation phones deploy GSM technology used for mobile communication. GSM (Global System for Mobile Communication) make use of digital modulation to

CDMA and GSM are the two types of technologies or way used in cell phones for transmitting the digital signal over the air . CDMA stands for Code Division Multiple Access as from the name it is clear that in this technologies the radio frequency are divided so that multiple user can access the same wireless spectrum . GSM stands for Global System for Mobile Communication as from the name it is clear that

The number one 3G network has introduced some new trendy, smart and featured phones for its customers. These phones were especially designed for 3G. These phones include the Jazz X phones as ‘Jazz Xcite (3G feature phone) and Jazz Xplore (smartphone series).

Gphone is associated with world-class manufacturers such as Broadsoft, and carriers including ATT, Qwest, Verizon, and Global Crossing. The staff members who represent GlobalPhone want to provide today’s high-tech telecommunication industry with a creative approach to enabling technology, with outstanding customer support and services offered at competitive rates.

Telephony-Phone Technology/Voice is the process of transmitting sounds electronically from one point to another. The technology is present in any industry that uses computers and phones. Telephony-Phone Technology/Voice is a process that is widely used in a day-to-day environment. The fast paced business market requires flexibility. Therefore, use of this type of technology allows for efficient productivity.

In the VoIP industry, these are defined as VoIP gateways or routers (if they support routing features) having capabilities to translate FXO or FXS signaling to SIP signaling. You could have two type of conversion with an Analog

The disadvantages og analog systems was overcome by second generation of cellular systems which represents data digitally.The first commercial deployment ogf 2G system called GSM was made in 1982.In 1993 as another 2G system also known as CDMAone(IS-95) was standardized and commercially deployed in south korea and hongkong in 1995, followed by united states in 1996.Upgrade to 2G systems offering higher data speeds called 2.5G systems was deployed.GSM has such two technologies calledhigh speed circuit switched data(HSCSD) and

The first generation (1G) only provided users with voice communication in its second generation (2G) the service was expanded to voice and data communication in which the system capacity was also improved. Second generation or 2G wireless technology is also known as Global Systems for Mobile Communications (GSM) and Code Division Multiple Access (CDMA). The third generation (3G) was a revolution in the cellular technology the data rates increased immensely from 2G, 3G is also known as Wideband CDMA (WCDMA) and CDMA-2000. The current cellular technology that are in existence is fourth generation (4G) also known as Long Term Evolution (LTE), which can theoretically provide data rates up to 100 Mbps.

This is a plug and play GSM Modem with a simple to serial interface. It is use for sending SMS, Calling (Answer and decline calls), and other GSM operations that are controlled by simple AT commands from micro controllers and computers. Highly popular SIM300 module is used for all operations. It comes with a standard RS232 interface for easy interface of modem to micro controllers and computers.

As the GSM uses the combination of Time and FDM, the mobile is used to demultiplex the given channel and also it is responsible for accessing the channel more effectively and efficiently. The mobile device is used to transmit and receive the required data within in a given time frame and with if a give condition. With the help of mobile devices, there are many other services offered by the GSM to enable ad to support more efficient data transmission. These services can be SMS, MMS etc. All these services can only be accessed with the help of mobile devices which supports may other multimedia features like live calling, video calling etc. Every day,

The booming revolution in Information Technology sector has pushed the India’s telecom market significantly. India has shown tremendous growth in past few years in terms of mobile services. Mobile phones are a vast improvement over the telecommunications technology of the past, and now become an important asset in today’s busy life. Mobile phones have become the necessity in today’s competitive environment to meet the emerging global economy.
