Sao Tome and Principe Cellular Signal Blocking Frequencies

Sao Tomé-et-Principe, a magnificent archipelago located in the Gulf of Guinea, benefits from increasing connectivity in cell phone. For various reasons, it may be necessary to block cell phone signals in certain specific areas. This article examines the cell phone networks available in Sao Tomé-et-Principe, providing information on operators and frequency bands used, in order to determine the appropriate frequency range to effectively block the signal.

Cellular operators and frequencies used:

In Sao Tomé-et-Principe, there are currently two main cell phone operators that offer mobile communication services. Here are their names and frequency bands they use:

Unitel t+ (união nacional para a independencia total of Angola)

Frequency bands used:

• GSM (2G): 900 MHz
• UMTS (3G): 900 MHz
• LTE (4G): 800 MHz (B20) and 1800 MHz (B3)

CST (Companhia Santomense of Telecomunicações)

Frequency bands used:

• GSM (2G): 900 MHz
• UMTS (3G): 2100 MHz
• LTE (4G): 1800 MHz (B3) and 2600 MHz (B7)

Frequency range to be covered to block the signal:

To effectively block the cell phone signal to Sao Tomé-et-Principe, it is important to cover the main frequency bands used by operators in the country. The key frequencies to be taken into account are as follows:

• GSM (2G): 900 MHz
• UMTS (3G): 900 MHz and 2100 MHz
• LTE (4G): 800 MHz (B20), 1800 MHz (B3), and 2600 MHz (B7)

By blocking these frequency bands, it will be possible to effectively disrupt cell phone signals to Sao Tomé-et-Principe.

Conclusion:

To block cell phone signals at Sao Tomé-et-Principe, it is essential to take into account the frequency bands used by cell phone operators in the country. UNITEL T+ uses GSM, UMTS and LTE frequency bands, while CST uses GSM, UMTS and LTE frequencies. The frequency range to be covered to block the signal effectively includes GSM (2G), UMTS (3G) and LTE (4G) frequencies mentioned above. By understanding this information, it is possible to set up suitable signal blocking devices to meet specific needs to Sao Tomé-et-Principe.
