Tech Tip – Using a Cell Phone’s Test Mode

July 17th, 2013

Q: What is putting a phone into Test Mode and how can I do it?

A: Putting a phone in Test Mode is a good way to accurately measure the strength of an available signal in a specific location. We urge people to use Test Mode because it provides an actual numerical measurement of signal strength. By contrast, the graphical “bars” representation displayed by most phones is a simple approximation of signal strength that varies widely among manufacturers and devices.

Test Mode displays the true strength of signal a phone is receiving in decibels (dB). The reading is always displayed as a negative number, and the closer to zero the stronger the signal. So a reading of -65 dB is much stronger than -95 dB.

The directions for accessing Test Mode vary among devices. For most Android devices, select “Settings” – “About Phone” then “Status” and look for signal readings, We have more information on putting your phone into test mode on our web site at:

Wilson Cellular Signal Tester

April 15th, 2013

Cellular Signal Tester

For building cellular signal booster installers, getting a cell signal strength reading to help calculate coverage area a building signal booster system will provide can be a challenge. If the signal booster installer is only concerned with one service provider, it’s fairly easy and straight forward – just put a cell phone into test mode or, for most Android devices, check Settings, About Phone, Status.

For larger installs where the need to boost the signal for multiple service providers, the installer could use a device for each provider or invest in a much more expensive spectrum analyzer. To meet this need at a more affordable cost, Wilson Electronics has developed an cellular signal strength tester that tests the wireless signal for most service providers in the US.

The Wilson Cellular Signal Tester allows the installer to test downlink signal strength before and after cellular amplifier system installation. It works with the 800 MHz , 1900 MHz, 2100 MHz) and 700 MHz LTE (bands 12 and 13) frequency bands for carriers like AT&T, Verizon, Sprint, T-Mobile and others.

Wilson also has a handy Directional Antenna kit to use with the device.

InIine Antenna Signal Booster

In-Line Antenna Signal Booster

On larger cellular signal booster system installations, sometimes the installer needs more power to an inside antenna or two. In Line antenna booster fits the bill.

An In-Line booster is typically be used in big buildings when you have long stretches of cable and you need to boost the signal to the inside antenna the cable is connected to. It is also used to compensate for signal loss because of the use of taps or splitters to accommodate multiple interior antennas.

The In-line Booster is installed between a the main in-building signal booster unit and that booster’s inside antenna.

The In-line Booster can be installed in the middle of a cable run or near the inside antenna, as needed.

At AlternativeWireless.com, we carry the full selection of Wilson Electronics Sleek Signal Boosters. We also carry Wilson’s complete line of antennas, components, mounts and accessories.

Confusing New Frequencies

In the cellular signal booster business, it used to be we only had to worry about 1 frequency in the US – 800MHz. Then along came Sprint with 1900MHz PCS. PCS gave us clearer sound, but weak signals gave us a dropped call and no service. With today’s 4G services, we now face a much larger array of confusing frequencies including 700MHz, 1700MHz, 2100MHz and 2500MHz. To complicate things more, 700MHz for Verizon is different than 700MHz used by AT&T.

Wilson To The 4G Signal Booster Rescue

To accomadate these newer frequencies and technologies, Wilson Electronics has expanded it’s small and mobile SLEEK signal booster line.

New from Wilson® Electronics is the Wilson® AG Pro 75™ in building cellular repeater system. The Wilson® AG Pro 75™ amplifier is designed to boost the cellular signal inside a building for both cell phones and cellular data cards. It will boost the signal for almost all cellular service networks in North America including AT&T, Sprint, Verizon, T-Mobile, Rogers. It does not work with for Nextel iDEN networks.

What’s Different?

Wilson Electronics already has 3 DualBand in-building cellular repeater systems including the Wilson SignalBoost Desktop, Wilson Small Office / Home Office (SOHO) and the Wilson SignalBoostDB Pro. Not to mention the variety of single band cellular amplifiers. The biggest differences are the Wilson AG Pro 75:

  • Has higher more gain (will cover larger areas)
  • Gain is manually adjustable for a custom install

The application for the AG Pro 75 will be for larger buildings.

More Features

The AG Pro 75™ is a dual band (800MHz / 1900MHz frequencies) amplifier. The amplifier gain is adjustable with control knobs on the front panel. The knobs enable the installer to adjust 800MHz and 1900MHz gains separately. The maximum amplifier gain is 75db for 1900MHz frequencies and 70db for 800MHz frequencies. The maximum gain on the AG Pro 75 is a substantial increase from Wilson’s previous highest gain amplifiers, their single band SmartTechnology cellular signal boosters. Being able to manually adjust the amplifier gain means the installer can more easily tune the amplifier for optimum gain specific to a particular installation and adjust according to the possible antenna separation and outside signal strength.

The AG Pro 75™ in-building cellular repeater is bidirectional and can boost the signal to and from the cell site. It is FCC type accepted and Industry Canada certified. It can be configured with current Wilson’s wide varity of building antennas and cable.

Cellular Amplifier Output Power and Gain

September 7th, 2010

When selecting a cellular amplifier there are many factors to consider. Two key specifications are amplifier gain and output power.

Cellular Amplifier Gain

Cellular amplifier gain is the number of times the power into the amplifier is increased at the output of the amplifier. Amplifier Gain is expressed in dB’s. (ex: 10 dB is a gain of 10 times, 20 dB is a gain of 100 times). For example, 1 watt into an amplifier which has 10 dB gain puts out 10 watts.

What if the amplifier is only capable of 3 watts output?

The amplifier is then over-driven. Too much input power results in 3 watts of distortion, just like yelling into a microphone and distorting a hi-fi system. The same happens to the cell phone amplifier, which causes it to interfere with adjacent channels on the cell site.

The maximum power that can be applied to a 10 dB 3-watt amplifier is .3 watts, which gives 3 watts of undistorted output. A cellular device (phone or datacard)  connected to a direct connection amplifier with normal cell phone maximum power (.2 watts) going into the amplifier and a gain of about 12 dB gives 3 watts of undistorted output power to the cell site. Any more input power would not increase the output, but only distort it, which causes harmful interference. A gain of 15 times is 11.8 dB.

Why do we need higher gain amplifiers?

An example is a 40dB,  3-watt cellular amplifier. We need more gain because when the cell phone has to transmit to and receive from the amplifier’s inside antenna (which is about 1-2 feet from the cell phone), the signal is much weaker into the amplifier than the .2 watts that was going directly into the direct-connection amplifier. The signal is now approximately 660 times weaker when it enters the amplifier’s input. It just so happens that a 40 dB gain amplifier will put out 3 watts with that input.

Different Gain for Different Applications

You can see that different gains are needed for different applications. Also, in an automobile situation with the outside antenna on the roof of the car and the inside antenna near the headrest, 40 dB is generally the maximum gain before the amplifier starts oscillating. A good cellular amplifier will shut down once oscillation occurs as to not cause harmful interference with other users on a cell tower.

With in-building applications, the cell phone is much farther from the inside antenna; therefore, a higher gain amplifier is needed. A 50 to 65 dB gain will generally give good coverage in most building applications dependent on outside signal strength. Amplifiers with higher gain require much greater antenna separation.  For example, a 72 dB gain amplifier requires 4 times more antenna separation distance than a 60 dB amplifier.
