When customers purchase Cell Phone Jammers, unless specified otherwise, the default factory settings do not include GPS signal blocking modules. However, if customers explicitly request the ability to block GPS signals while blocking all mobile signals, manufacturers can add GPS frequency band blocking modules to the devices. This article will explore the reasons why small power Cell Phone Jammers do not include GPS frequency bands in their default configuration.
Reason 1: Weak or Absent GPS Signals in Indoor Environments
The first reason is that small power Cell Phone Jammers are primarily used in fixed indoor environments where GPS signals are often weak or even absent. In such cases, the GPS signal blocking function would be rendered useless. Therefore, manufacturers prioritize allocating signal blocking modules to the mobile signal frequency bands to maximize the jamming performance for mobile signals.

Reason 2: Focus on Mobile Signal Blocking
The second reason is that small power Cell Phone Jammers are designed with the primary purpose of blocking mobile signals. To ensure optimal performance in blocking mobile signals, manufacturers choose to allocate a higher number of effective signal blocking modules to the mobile signal frequency bands. This decision is based on the understanding that the demand for blocking mobile signals is generally higher than the demand for blocking GPS signals.
Reason 3: Multiple Satellite Navigation Systems
It is important to note that the term “GPS” in this context refers to satellite navigation signals in general and not just the GPS navigation signals from the United States. In reality, satellite navigation systems include not only the GPS system but also China’s Beidou, Europe’s Galileo, Russia’s GLONASS, and others. When adding GPS signal blocking modules, it is necessary to ensure effective coverage of all these satellite navigation systems.
Small power Cell Phone Jammers do not include GPS frequency bands in their default configuration due to several reasons. These include the weak or absent GPS signals in indoor environments where these jammers are primarily used, the focus on blocking mobile signals, and the need to consider multiple satellite navigation systems. However, manufacturers can customize the devices to include GPS signal blocking modules upon specific customer requests.
