What does field test mode do?

What does field test mode do?

Field Test Mode on Android Phones SignalStream shows field test information under the “Signal Info” tab, but it also allows you to take, save, and optionally share 3G, 4G, and 5G signal readings with our team of SIgnal Specialists, who can recommend a booster.

What is a field mode?

The mode of electromagnetic radiation describes the field pattern of the propagating waves. Plane waves, waves in which the electric and magnetic fields are both orthogonal to the direction of travel of the wave. These are the waves that exist in free space far from any antenna.

How do you read field test mode?

To open the field test mode on an Android Phone, start the phone app, enter *#*#4636#*#* and after you enter the last asterisk a menu displays with options for Phone Information, Battery Information, Battery History, Usage Statistics, and Wifi Information.

What is ASU in signal strength?

Arbitrary Strength Unit (ASU) is an integer value proportional to the received signal strength measured by the mobile phone. It is possible to calculate the real signal strength measured in dBm (and thereby power in Watts) by a formula.

What is good Rsrq value?

RSRQ – Indicates quality of the received signal, and its range is typically -19.5dB(bad) to -3dB (good).

What is TE and TM modes?

The difference between TE and TM mode is that TE stands for transverse electric mode while TM stands for transverse magnetic mode. TE mode is also known as H mode as there is only a magnetic field along the direction of propagation.

Should ASU be high or low?

The normal signal ranges from roughly -60dbm to -112dbm. The higher the absolute number (120 is higher than 80), the lower the signal. ASU is the rate at which the phone is able to update its location from the tower signals. It’s linear.

What is a good ASU?

The valid range of ASU is from 0 to 97. For the range 1 to 96, ASU maps to. (ASU – 143) < dBm ≤ (ASU – 140). The value of 0 maps to RSRP below -140 dBm and the value of 97 maps to RSRP above -44 dBm. On Android devices however, the original GSM formula may prevail for UMTS.

What can cause poor RSRQ?

Poor RSRQ reasons:

• Bad RSRP.
• Overshooting from neighbor cell.
• Less intersector seperation of the same site.(65deg is good) 4.High utilization of the cell( If the utilization increases the RSSI increases which degrade the RSRQ).
