We can enjoy the Global System for Mobile Communications (GSM) with all its benefits in everyday life. However, the advantages and disadvantages of GSM cannot be denied and need to be taken into consideration.
The advantages and disadvantages of GSM include technology, network, signals, and compatibility with various devices.
In this article, we will share 20 advantages and disadvantages of GSM that you need to know to consider when using it.
Advantages of GSM
Cost-effective: GSM provides highly cost-effective products and solutions.
Seamless roaming: GSM provides seamless wireless connectivity, making international roaming a non-issue.
Faster data speeds: Advanced versions of GSM, such as GPRS and EDGE, with more antennas provide high-speed data downloading and uploading.
High transmission quality: SAIC and DAIC techniques provide very high transmission quality. SAIC stands for Single Antenna Interference Cancellation technique, while DAIC stands for Double Antenna Interference Cancellation.
Easy maintenance: GSM network maintenance is easy because network technicians are available in large numbers at affordable costs. This helps increase telecommunications operator revenues.
SIM card flexibility: This phone works based on SIM cards, so it is easy for users to switch between different types of phones. It also allows users to save their data and preferences.
Good voice quality: GSM signals do not suffer from quality degradation inside offices and homes and offer good voice call quality due to the digital coding and error correction techniques used.
Easy integration: GSM technology is easy to integrate with other wireless technologies, such as CDMA and LTE.
Built-in security: GSM combines encryption and authentication measures, making it more secure than analog systems.
Vendor interoperability: GSM specifications allow devices and networks from different vendors to work together without technical issues.
Energy efficient: GSM technology is energy efficient, which is important for mobile devices with limited battery capacity.
Disadvantages of GSM
Spectrum licensing required: Operating a GSM network requires a radio spectrum license from the relevant national telecommunications regulator, which can involve significant cost and administrative complexity depending on the country.
Coverage extension costs: To increase coverage, it is necessary to install repeaters, adding to infrastructure costs.
Limited data rates: GSM provides limited data rate capabilities; for higher data rates, more advanced versions of GSM technology are used.
Bandwidth sharing: GSM has limited bandwidth. Multiple users share the same bandwidth, which can cause interference when many users use the GSM service simultaneously.
Electromagnetic interference: GSM’s pulse-based transmission can interfere with certain electronic devices, which is why some environments like hospitals and fuel stations have historically restricted its use.
Security vulnerabilities: Even though they are encrypted, GSM networks are vulnerable to hacking and eavesdropping, particularly with older encryption algorithms.
Limited rural coverage: Although widespread, GSM coverage may not be available in very remote or undeveloped areas, or in areas primarily served by other cellular technologies such as 4G LTE and 5G NR (New Radio).
Backhaul dependency: GSM network performance depends on the quality and capacity of the backhaul infrastructure, which may be inadequate in some areas.
Device compatibility: Older GSM devices may not be compatible with newer networks and may require users to upgrade their devices.
Common GSM Network Problems and How to Fix Them
Here’s a quick look at common GSM issues and practical ways to address them:
- Weak indoor signal: Use a signal booster to improve coverage.
- Network congestion: Reallocate channels to reduce the load.
- Interference from other devices: Keep GSM devices away from sensitive electronic devices.
- Poor coverage in rural areas: One solution is to use a GSM repeater.
- Compatibility with older devices: Check the frequency bands supported by the device.
Here are some of the advantages and disadvantages of GSM that you may wish to consider when using this technology. We hope this article will be useful in expanding your knowledge of GSM.
