Cellular Radio Interference FAQs

​Radio systems operate on assigned frequencies. This allows different services such as mobile radios, local wireless networks, and others to operate without transmitting on the same frequency. When different wireless services are broadcasting on the same frequency it can cause signal collisions and interference. Most interference is caused by powered wireless equipment inadvertently broadcasting on licensed radio frequencies.​

There are several potential causes of interference, and any powered wireless device has the ability to generate interference. Here are some of the most common sources:

• Cellular boosters
• Amplified TV antennas
• Wireless home phones, baby monitors, and microphone systems
• Wireless modems and routers

​Cellcom towers use FCC licensed frequency, and Cellcom is legally obligated to operate its cellular network in accordance with FCC regulations. This includes keeping our network free of interference to ensure that subscribers on the network have the best experience possible. Cellular interference can cause issues with 911 calls and other emergency services, which has a negative impact on public safety.​

Cell Site Technicians use information from cell site monitoring and specialized equipment to identify and locate the most likely source of cell site interference.​

A Cellcom RF Technician can suggest possible sources of interference and help to identify external equipment that may be a source, such as antennas. If the source of interference is not clear, it is best to power off any equipment that could potentially cause interference, and verify the interference subsides. Then the equipment can be powered up, one by one, to determine which device is responsible. In some cases, a Cellcom RF Technician may ask to coordinate with you in person to troubleshoot the issue locally.

In many cases, the equipment generating the interference may be working properly. It is also possible for equipment to start generating radio interference after not causing an issue previously.

Cellcom RF Technicians will arrive in a marked Cellcom company vehicle, hold a Cellcom identification badge, and will always identify themselves. If it is necessary to enter a home or business to troubleshoot, they will always ask for consent prior to entering and follow any necessary precautions.​

Cellcom will make all reasonable attempts to resolve the issue in a way that works with your schedule and availability. If you choose not to cooperate or the interference is especially severe, Cellcom may choose to refer the case to the FCC or other proper authorities for investigation. Most consumer electronics are governed by FCC Part-15 rules, and these rules allow you to operate the device under the condition that it does not interfere with licensed radio networks, including the Cellcom network.​

Once the source of interference has been identified, the RF Technician may visit your home or business to leave a door hanger. This hanger includes general information on cellular interference, potential sources of interference, and how to contact Cellcom.​

​Cellcom will make a reasonable attempt to find a solution that allows you to use your equipment without generating interference. If the equipment is defective and generates radio interference when it is operated, the equipment will need to be powered down or replaced. Cellcom is not responsible for replacing or compensating you for equipment that generates interference.​
