A standard development was done by ETSI i.e. European telecommunication standard group in order to show the protocols for second-generation (2g) networks of the digital cellular world. This standard was called GSM which stands for Global System for Mobile Communication. The first generation (1g) was replaced by this 2g network in the cellular world. This idea was originated in the year 1970s in Bell Laboratories during the working on a cell-based mobile radio system.
GSM Full Form
GSM is a widespread network in over 200 countries worldwide, digitally. It is a radio network. It works on TDMA technology. TDMA stands for Time Division Multiple Access in a narrowband. This global system is growing to slow in Asia and America while it is already fully developed in Europe. This technique is used for sending texts, calling, data using, etc. GSM is also laptop compatible. An individual can connect their cell phones to the laptop for email, browsing the internet and checking security to make them GSM enabled.
There are three different frequencies on which GSM standard operates such as:
- 900MHz: This is the frequency of the original GSM system.
- 1800MHz: In order to support multiple numbers of growing subscribers this frequency was used.
- 10900MHz: It is specifically US-based frequency.
GSM supported Data Applications
When a GSM compatible phone is connected to a laptop many functions are enabled such as:
- Internet: One of the good speeds and great functionality of the internet can be achieved by using GSM. It is wireless in nature.
- Mobile fax: It is an easily accessible and connectable fax service at any area where GSM is enabled.
- LAN access that is secured: GSM provides secured access for corporate LAN. It encrypts the air links and provides additional security for confidential e-mails and faxes.
Advantages of GSM
- Since GSM service is obtained over 200 countries, so it provides worldwide roaming for its clients to roam throughout the world.
- GSM is extraordinarily secured as a result of its devices and facilities can not be simply duplicated.
- It has in-depth coverage all told over the planet.
- Clear voice calls and efficient use of spectrum.
Compatible with a wide range of handsets and accessories.
- Advanced options like short messages, caller ID, Call hold, Call forwarding, etc.
- Compatible with Integrated Services Digital Network (ISDN) and alternative telephone services.
Disadvantages associated with GSM
- The biggest disadvantage of GSM is that multiple users share a similar information measure. this could cause interference and because of interference information measure limitation happens.
- The other disadvantage of GSM is that it should cause electronic interference. This is one of the important reasons behind the sensitive locations like hospitals and airplanes need a telephone to be turned off otherwise it will produce interference with the equipment of hospitals and airplanes.
