Summary of the Article
GSM (Global System for Mobile Communications) is a widely used mobile communication technology with both advantages and disadvantages. Some key points about GSM include:
- Electronic interference can occur with GSM due to its pulse-transmission technology.
- Interference from GSM can affect electronics like hearing aids, which is why certain places like airports, gas stations, and hospitals require mobile phones to be turned off.
- Comparison between CDMA (Code Division Multiple Access) and GSM:
- Signal detection is difficult in CDMA, while it is easy in GSM.
- CDMA provides built-in encryption, while additional encryption is required for GSM as it does not have built-in encryption.
- CDMA enables limited roaming, whereas GSM enables worldwide roaming.
- GSM-based home automation systems have a disadvantage of multiple users sharing the same bandwidth, leading to potential interference.
- 3G and other faster technologies have been developed on different networks, such as CDMA, to overcome bandwidth limitations of GSM.
- GSM offers more expansive international roaming capabilities compared to CDMA, which only offers nationwide roaming.
- LTE (Long-Term Evolution) supports only data transmission, while GSM supports both data and voice.
- Some networks, like AT&T, have already shut down their 2G and 3G GSM networks, making GSM phones obsolete.
- CDMA has disadvantages such as lack of international roaming capabilities compared to GSM and difficulty in upgrading or changing to another handset.

What are the disadvantages of GSM based home automation
Perhaps the greatest disadvantage of GSM is that multiple users share the same bandwidth. With enough users, the transmission can encounter interference. Therefore, faster technologies, such as 3G, have been developed on different types of networks than GSM, such as CDMA, in order to avoid such bandwidth limitations.

Which is better GSM or LTE
LTE supports only data transmission, whereas GSM supports both data and voice. People have a tendency to trust LTE when they need highspeed Internet, but they tend to trust GSM when they primarily need to make phone call.
Are GSM phones obsolete
But in 2022, it's absolutely time to get off of CDMA and GSM. Those networks are going away! If you have a phone that only uses 2G or 3G, you need to get a 4G or 5G phone, pronto. AT&T has already shut down its 2G GSM network and most recently said it will shut down 3G GSM/UMTS in February 2022(Opens in a new window).
What are the drawbacks of CDMA
Disadvantages of CDMA
When compared to GSM is the lack of international roaming capabilities. The ability to upgrade or change to another handset is not easy with this technology because the network service information for the phone is put in the actual phone unlike GSM which uses SIM card for this.
What are 2 major drawbacks to using CDMA
Disadvantages of CDMA :Time synchronization is required.It can't offer international roaming, a large GSM advantage.The CDMA system performance degrades with an increase in the number of users.A network of CDMA is not mature because it is relatively new with GSM.
What is GSM advantage and disadvantages of GSM
➨GSM provides limited data rate capability, for higher data rate GSM advanced version devices are used. ➨GSM uses FTDMA access scheme. Here multiple users share same bandwidth and hence will lead to interference when more number of users are using the GSM service.
Is GSM obsolete
