If you have ever wondered about the strength of your phone’s signal, you may have noticed strange acronyms like dBm and ASU displayed on your device. Understanding these terms is critical, as they can indicate the quality of your cell phone reception. If you’ve recently noticed your phone signal strength displaying as 103 dBm 5 ASU, you might be curious what it means. In this blog post, we’ll dive into what these numbers represent and how you can interpret them to optimize your mobile experience.

My Phone Signal Strength Is Showing 103 Dbm 5 Asu What Does It Mean

When we talk about the phone signal strength, we use two different parameters, one is dBm and the other is ASU. Here, in this scenario, the signal strength of the phone is showing 103 dBm 5 ASU. dBm is a logarithmic unit of measurement that represents the power of the received signal in decibels relative to one milliwatt. On the other hand, ASU (Arbitrary Strength Unit) is a relative signal strength indicator calculated by the device. It ranges from 0 to 31, where 0 typically means no signal, and 31 means excellent strength.

With the values of 103dBm and 5 ASU, it can be inferred that the phone’s signal strength is generally weak, as the dBm reading is negative. A dBm reading of -100 is a borderline signal strength, meaning the phone can still make and receive calls and access the internet, but the signal may be intermittent, slow, or dropped at times. The ASU value of 5 also confirms that the signal strength is not very strong, but it is not zero either.

This could mean that the user is in a location where the cellular tower is not very close or the building structure is hindering the cell tower’s signals from reaching their phone. However, with these values, a user can still try to improve their phone’s signal strength, like moving to an area with better coverage or using a signal booster.

What Do The Terms Dbm And Asu Stand For?

When you check the signal strength on your mobile phone, you may see that it is measured in both dBm (decibel-milliwatts) and asu (arbitrary strength unit). A signal strength of 103 dBm and 5 asu means that the mobile signal is below average and is very weak. dBm is a unit of measurement that represents the strength of the signal, with higher negative values indicating weaker signals. Asu, on the other hand, is a value that is calculated from the signal’s measured strength and is used in some networks.

The ideal signal strength on your mobile phone should be between -50 dBm and -80 dBm, with a value closer to 0 dBm indicating a stronger signal. Anything below -90 dBm is considered poor, with poor signal being areas where mobile coverage can be intermittent or nonexistent. In this case, a signal strength of 103 dBm and 5 asu is weak and signals can be lost if you move around while talking. The signal strength is affected by factors such as the distance from the network towers or obstacles that obstruct the signal.

In conclusion, a weak signal on your mobile phone can result in dropped calls and slower internet speeds. It is essential to check the signal strength at different locations to find out where the signal is stronger. If you find that the signal is consistently weak, you can consider getting a signal booster or changing your service provider. Remember that a strong mobile signal is an essential factor to ensure that you stay connected with your friends and family without any interruptions.

How Is Signal Strength Measured On A Phone?

A mobile phone signal strength is measured in decibels (dBm) and asu (arbitrary signal unit) which is an indication of the phone’s power level. A higher number of asu indicates a stronger signal, while a higher dBm number indicates a weaker signal.

A signal strength of 103 dBm 5 asu implies a weak signal level since it is closest to -110 dBm, which is the maximum weak signal strength. This means that the phone is possibly struggling to connect to a network, and it may result in a delay in making or receiving calls, and sometimes dropping calls. It can be caused by several factors such as distance from the nearest cell tower, signal interference, or dead zones in your area.

To get better signal strength, you can try to move closer to a cell tower or switch to another carrier; you can also try resetting your network settings or turning off any objects that could cause interference such as Bluetooth or Wi-Fi. In some situations, the signal strength meter may not represent the actual signal strength, and it can change frequently. In such a case, one should not rely entirely on the reading for determining signal strength as it may not be accurate.

What Is A Good Signal Strength Range For A Phone?

Mobile phone signal strength is an important factor in ensuring seamless communication. While many people take for granted the quality of the network available at a particular location, it is important to understand what the signal strength of a phone means. When a phone signal strength is showing 103 dBm 5 asu, it means that the device is picking up 103 decibels per milliwatt of power, which is considered a reasonably strong signal. Additionally, the 5 asu indicates the number of active signal bars present on the phone’s display.

A decibel (dBm) is a measurement unit used to determine the signal strength of a phone. It ranges from -120 to 0, with 0 indicating an outstanding signal quality, while -120 represents the minimum allowable signal strength for a phone to work. Therefore, the closer signal strength is to 0 dBm, the better the quality of the network signal. On the other hand, the asu (arbitrary strength unit) is a relative unit of measurement that signifies the number of signal bars on a phone. Thus, 5 asu translates to five signal bars on the phone’s display, while 0 asu means no signal bars are showing.

The signal strength of a mobile phone device can vary depending on the location, the terrain, the weather, and the network provider. When in low signal areas where the signal strength is below -100 dBm or 1 asu, it is highly likely that there will be a drop in connectivity, and users may experience issues such as slow download speed, delayed text messages, or calls dropping. Knowing the signal strength of a phone is critical in ensuring a reliable and effective communication experience, especially when at hard to reach locations.

Can Factors Such As Location And Network Provider Affect Signal Strength Readings On A Phone?

Mobile communication networks use signal strength measurements to determine the quality and reliability of the signal being transmitted between the mobile device and the cell tower. When a mobile phone signal strength is displayed, it is often represented by two metrics: dBm and ASU (arbitrary signal units). In this case, the signal strength is showing 103 dBm and 5 ASU.

dBm measures the intensity of the signal in decibels, with a lower value indicating a stronger signal. Typically, signal strength between -50 dBm and -95 dBm is considered acceptable for mobile devices. In this case, the signal strength of 103 dBm is quite weak and may result in poor voice quality, slow data transfer, or even loss of connection.

ASU is a relative measure of the signal strength, ranging from 0 to 31, where 31 represents the strongest signal and 0 indicates no signal at all. Five ASU is equivalent to approximately -99 dBm, indicating a relatively weak signal that may impact the performance of the mobile device. This is especially true when the device is situated in a location with a lot of interference, such as in a building with thick walls, or in an area far away from the cell tower.


In conclusion, a phone signal strength of 103 dBm 5 asu means that the signal strength is poor and potentially unstable. A strong signal strength typically falls between the range of -50 dBm to -85 dBm, while anything above -100 dBm is considered a weak signal. Additionally, the accompanying 5 asu refers to the number of signal bars displayed on the phone, indicating that the signal is so weak that it cannot even produce a reliable signal bar reading. It’s important to note that weak signal strength can vary based on factors such as location and network congestion, but in general, a stronger signal strength leads to better call quality, faster data speeds, and a more reliable connection.
