GSM’s Advantages
The following are some of the benefits of GSM: GSM technology has been refined through time, and GSM mobile phones and modems are widely accessible around the world.
It offers products and services that are extremely cost-effective.
Because GSM-based networks (i.e. base stations) are used all over the world, the same mobile phone may be used anywhere. This saves money while also providing smooth wireless access. Users will be able to use Internet and phone services without interruption as a result of this. As a result, international roaming is not an issue.
Advanced GSM versions with a larger number of antennas will allow for faster data download and upload.
The transmission quality of SAIC and DAIC approaches is quite excellent. Single Antenna Interference Cancellation (SAIC) and Dual Antenna Interference Cancellation (DAIC) are two different types of interference cancellation techniques.
The availability of a large number of network engineers at a low cost makes it simple to maintain GSM networks. The telecom operators would be able to boost their income as a result of this.
Because the phone is based on a SIM card, users may easily switch between different types of phones.
The GSM signal does not deteriorate within the workplace or at home.
GSM is simple to combine with other wireless technologies such as CDMA and LTE. Etc
GSM’s disadvantages
The following are some of GSM’s drawbacks: Many GSM technology are copyrighted by Qualcomm, thus licenses must be obtained from them.
Repeaters are necessary to be added in order to expand coverage.
GSM has a restricted data rate capacity; upgraded version GSM devices are utilized for larger data rates.
The FTDMA access mechanism is used by GSM. When a large number of customers utilize the GSM service, several users share the same bandwidth, resulting in interference. Robust frequency correction techniques are employed in mobile phones and base stations to avoid this problem.
GSM employs pulse-based burst transmission technology, which causes interference with some gadgets. As a result, GSM-based mobile phones and other devices are prohibited on flights, gas stations, and hospitals.
