Summary of the Article – Advantages and Disadvantages of GSM and CDMA
1. Difficult Signal Detection in CDMA: The signal detection process is challenging in CDMA.
2. Easy Signal Detection in GSM: On the other hand, signal detection is easy in GSM.
3. Built-in Encryption in CDMA: CDMA provides built-in encryption for secure communication.
4. Additional Encryption in GSM: GSM requires additional encryption as it doesn’t have built-in encryption.
5. Limited Roaming in CDMA: CDMA enables limited roaming capabilities.
6. Worldwide Roaming in GSM: GSM allows for worldwide roaming.
Key Questions and Answers
1. What are the disadvantages of GSM based home automation?
Perhaps the greatest disadvantage of GSM is that multiple users share the same bandwidth, which can lead to interference. Faster technologies like 3G have been developed on different networks to avoid this limitation.
2. What are the major advantages of using GSM?
GSM offers a more suitable network with robust features, no roaming charges on international calls, worldwide connectivity, and extensive coverage. It also uses SAIC and DAIC techniques for high transmission quality.
3. What is the longest distance supported by GSM?
The GSM specification supports a practical use distance of up to 35 kilometers (22 miles). In some cases, an extended cell concept can increase the radius depending on antenna systems, terrain, and timing advance.
4. What are the limitations of CDMA?
CDMA has a time delay in sending and receiving signals or data, doesn’t support international roaming, and its performance degrades with an increase in the number of users.
5. Why is GSM better than CDMA?
GSM provides more expansive international roaming capabilities compared to CDMA, which only offers nationwide roaming. GSM has service availability in over 200 countries, allowing customers to access network services worldwide.
6. Is GSM obsolete?
As of 2022, it is recommended to transition from CDMA and GSM networks as they are gradually being phased out. If you have a 2G or 3G phone, it is advisable to upgrade to a 4G or 5G phone. Networks like AT&T have already shut down their 2G GSM network and plan to shut down 3G GSM/UMTS in February 2022.

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.

What is the longest distance supported by GSM
The longest distance the GSM specification supports in practical use is 35 kilometres (22 mi). There are also several implementations of the concept of an extended cell, where the cell radius could be double or even more, depending on the antenna system, the type of terrain, and the timing advance.
What are the limitations of CDMA
The time required for sending and receiving signals or data is at once. It does not work in international roaming. The performance of the CDMA system degrades with an increase in the number of users.
Why is GSM better than CDMA
GSM offers more expansive international roaming capabilities than the CDMA, which offers only nationwide roaming. GSM can provide international roaming since its service is available in more than 200 countries, allowing its customers to access network services worldwide.
Is GSM 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 limitations of home automation system
Cost: One of the main drawbacks of home automation is the cost. Smart devices and systems can be expensive, and the cost can add up quickly if you want to fully automate your home. Reliance on Technology: Home automation also means that you are relying on technology to control various aspects of your home.
What are the advantages of GSM vs CDMA
GSM offers more expansive international roaming capabilities than the CDMA, which offers only nationwide roaming. GSM can provide international roaming since its service is available in more than 200 countries, allowing its customers to access network services worldwide.
What are the two uses of GSM
GSM automates and encodes the information before transmitting it via a channel including three distinct streams of user information inside each time slot. For the vast majority of the world, it is also the leading 2G digital cell phone standard. It governs how cell phones interact with the land-based tower system.
What is the range of GSM transmission
The uplink frequency range specified for GSM is 933 – 960 MHz (basic 900 MHz band only). The downlink frequency band 890 – 915 MHz (basic 900 MHz band only).
Why GSM is preferred over CDMA
GSM offers more expansive international roaming capabilities than the CDMA, which offers only nationwide roaming. GSM can provide international roaming since its service is available in more than 200 countries, allowing its customers to access network services worldwide.
What is difference between CDMA and GSM
GSM does not come with built-in encryption. CDMA comes with built-in encryption. The GSM technology offers less security as compared to the CDMA technology. The CDMA technology offers more security as compared to the GSM technology.
Does GSM and CDMA matter anymore
There's no technological difference between "CDMA" and "GSM" carriers any more in the age of 4G LTE and 5G. Some cultural differences remain, though. Specifically, Verizon makes it really hard to move your SIM card between devices without their permission, while it's easier to do so on AT&T and T-Mobile.
Does 5G use GSM or CDMA
The latest 'GSM' is 5G – the fastest mobile internet yet, of which most people haven't really experienced the true power of yet. Mobile technology is now fast enough to provide stable internet for most of the everyday tasks we use the internet for BUT we always want more.
Does GSM still work in USA
All major US cellular networks shut down legacy 3G support in 2022. AT&T shut down its 3G GSM network in late February, T-Mobile began shutting down part of its network at the end of March, and Verizon officially sunset its legacy network on December 31.
Is T-Mobile getting rid of GSM
T-Mobile recently disclosed that it will turn off its 2G GSM network on April 2, 2024.
What are two limitations of automation
Disadvantages:There are initial implementation costs of automation which can make it daunting to actually get started with.Automated processes are also less flexible than humans.Automation still requires human interaction.
What are the 5 disadvantages of automation
Comparison Table for Advantages and Disadvantages of Automation
| Advantages | Disadvantages |
|---|---|
| Increased productivity | Needs large capital expenditure |
| More efficient use of materials | Can become redundant |
| Better product quality | Could introduce new safety hazards |
| Improved safety | Still requires human intervention |
Are Verizon phones GSM or CDMA
CDMA
The Verizon network is a CDMA wireless network.
What are the 3 different types of GSM
The GSM network is divided into three major systems: the switching system (SS), the base station system (BSS), and the operation and support system (OSS).
Is GSM used anymore
GSM simply is a wireless network for transmitting data across mobile devices. It has been misunderstood as a mobile phone in some countries and still is even today. However, GSM is not a mobile phone but a means of communication across digital cellular devices. GSM is simply for wireless data transmission.
Does GSM work everywhere
GSM offers more expansive international roaming capabilities than the CDMA, which offers only nationwide roaming. GSM can provide international roaming since its service is available in more than 200 countries, allowing its customers to access network services worldwide.
What voltage does GSM supply
In this tutorial, our gsm module requires a 12 volts input. So we feed it using a 12V,1A DC power supply.
Is GSM going away
All major US cellular networks shut down legacy 3G support in 2022. AT&T shut down its 3G GSM network in late February, T-Mobile began shutting down part of its network at the end of March, and Verizon officially sunset its legacy network on December 31.
