Reasons for weak signal
Building Materials, Low E Glass
UV Radiant Barrier/Tek Wrap
Number one reason for poor cell signal
Cell tower
Distance from Tower
Steel, Concrete, Brick, Stucco
Lets talk a little bit about cellular signals, specifically weak cellular signals. One of the primary reasons for poor cellular service is signal blockage due to building materials. Most modern building materials designed to improve energy efficiency by blocking heat gain or loss will tend to block cell signal as well. These include radiant barrier liner, Low e glass, metal or tile roofing materials etc. These materials can seriously degrade an otherwise adequate signal on the side of a structure away from a cell tower or inside the structure itself. Heavy construction materials like concrete and steel found in commercial spaces and parking garages also block signal. In addition, many areas of the country have challenging terrain or foliage issues to overcome, and finally distance from a tower can also contribute to the problem.

To understand how to improve cellular signal it’s helpful to understand what constitutes cellular signal. The FCC has allocated 5 frequency bands to the cellular industry for voice and data transmission. As you can see on this slide, different carriers use different frequency bands for different functions; some use the lower frequency bands for hi speed data, some use the higher frequency bands and so on. To further complicate matters, carriers use different bands for different purposes in different locations. Later in this training we’ll talk about how you can determine what specific frequency channels are used by each carrier in a given location. All of the frequency bands used by the cellular carriers are considered Ultra High Frequency (UHF) and have specific properties that it is helpful to understand. First and foremost, the UHF signal path is what is called the "line‐of‐sight" path between the transmit and receive antennas. The curvature of the Earth is the primary limiting factor for the maximum distance a UHF signal can travel. The signal will travel outward from the transmitting antenna until it reaches the horizon. Beyond that point, the signal is blocked by the Earth itself, and reception is no longer possible for a receiver located on the surface.
It is for this reason that height is your friend. In very weak signal scenarios, the higher up you can get the input antenna, the better chance you have of picking up a usable signal. It's important to note, however, that the optical horizon (the horizon you can see) and the "radio horizon" are not quite the same. In reality, signal waves do not quite travel in a straight line as they move away from the transmitting antenna. Instead, the signal travels in a slightly downward curved path that keeps it nearer to the Earth's surface, thus extending its path a little further than the optical horizon and giving you the opportunity to pick up a usable signal even from a far away tower.
Cell Phone Signal
• Cellular signal strength is measured in decibel milliwatts or (dBm), and will typically
range from -50dBm (Strong) to -110dBm (No Signal)
• Every 3dB doubles or halves the power. A -67dBm is twice the power of -70dBm
• Every 6dB increase in signal strength will double the coverage area
Dropped calls
Cellular signal is measured in Decibel Milliwatts or dBm. This unit of measurement is important to understand because it is a negative scale. Typical cell signal will range from the low ‐60s, which is very strong, to the ‐90s, which is pretty weak. Calls will begin to drop at approximately ‐95dBm and weaker. Take a look at the scale, the more negative the number, or farther from zero, the weaker the signal. Also note that every three dB you gain or lose will double or halve the power and every 6dB of gain you add will double the coverage area.
3G or 4G?
Dual-Band boosters (3G) boost signal on 850 MHz and 1900 MHz bands.
Band 5
Band 25/2
Five-Band boosters (4G) boost signal on 700 MHz, 850 MHz, 1900 MHz and AWS (1700mHz
& 2100mHz).
Band 12/17 & 13
Band 5
Band 25/2
Band 4
Most phones today use 3G for voice, 4G or LTE is used for high speed data.
All Wilson Boosters will work with any device, 3G or 4G. A 4G booster also boosts 3G, and
4G devices use 3G when 4G is not available.
Carriers are rapidly deploying “voLTE” or “voice over LTE” (4G) to gain network capacity
Carrier Aggregation, or CA ,allows a single cell phone to use small slivers of all five bands simultaneously
to increase bandwidth (high speed data).
Legacy data and voice technologies will continue to be broadcast for some time, but are slated to be
“sunset” sometime within the next five years or so.
Lets talk a little bit about the specific application we’ll be using these cellular signals for. You’ve probably heard the term machine to machine or M2M. This is a broad label that is used to describe any technology that enables networked devices to exchange information and perform actions without the manual assistance of humans. M2M communication in this application is used for remote monitoring of the EV Charging Stations. At this point in time, most M2M communications are done using 3G technology but that is going to change in the not too distant future. As 4G networks become more widespread and the need to transmit more data continues to accelerate, 4G M2M communications will become more common. It’s important to understand this distinction because, as we mentioned earlier, different frequencies are used for different purposes so knowing what frequencies need to be amplified is critical.
How Boosters Work
Input Antenna
Output Antenna
Wideband Directional or Input Antenna – Talks to tower
Booster- Adds gain to the signal
Panel or Output Antenna – Talks to devices
A cellular booster is really a three part system which amplifies whatever cell signal it can pick up. The first component in the system is a high gain, directional input antenna which sends to, and receives from, the cell tower. It is a much higher gain antenna then the tiny antenna inside a cell phone or M2M device. The high gain directional antenna is connected to the input side of the amplifier (labeled Outside Antenna) with coax cable, we recommend RG11 because it has low signal loss characteristics. The booster adds gain and power to the signal, and is the only powered part of the system. It should be mounted indoors and protected from excessive heat or cold as well as moisture. The final component is the output or panel antenna which communicates with the cellular devices. The panel antenna is connected to the output side of the booster (labeled Inside Antenna). Depending on installation needs and available outside cell signal, a Wilson cellular booster system can be expanded by adding additional output antennas, although this is not something you will typically need to do to support EV Charging Stations. 7
Cellular Site Survey
Wilson RF Signal Meter
Reads all carrier’s signals
Essential tool for
professional installers
Performing a Cellular Site Survey: In this section we’ll talk about performing a Cellular Site Survey and understanding the results. We’ll cover the tools you’ll need and how to use them in a pre‐installation/evaluation application. Using the theories and concepts we just covered, a site survey will allow you to determine; what the relative and actual signal strength is at a given location by frequency and carrier, whether or not a booster is needed to ensure reliable communication, which booster you should use given actual signal strength and what the expected level of performance will be after installation.

• Predictable results
Directional Antenna Kit
There are several tools that are essential to performing a quality site survey. The first of which is the Wilson Electronics Signal Meter which is an essential tool for understanding the RF environment. With it, you can quickly determine what kind of results you will achieve, as well as identify any potential problems, before you begin the install! The meter is capable of reading all cellular signals, from all of the cellular carriers. With the directional antenna kit, it becomes a directional signal finder.
Before using your new signal meter, take the necessary time to learn how to operate the device. Without a thorough understanding of its use, the signal meter will be of little value. In order to conduct a “Site Survey”, you will need to learn how to look up specific carrier frequencies for the area you are working in. Take the time to create a note book and record your searches so you have a reference for each zip code in your service area. This will prove invaluable as you are called back to work in those areas again. Complete and easy to follow instructions on how to operate your meter, and do a frequency search, are included with the signal meter. Please take the time to read the Signal Meter instructions fully each time you perform a site survey until you are very comfortable with the process as this will ensure consistent, accurate results.
Cell Tower Locations by Carrier/Zip Code
There are several web sites that provide valuable information you need to perform a quality site survey. The first of these is www.cellreception.com. Prior to visiting the charging station site go here, enter the zip code or city/state and click on “All Towers” to see nearby cell tower locations on a Google map. Look at each of the 4 carriers individually to see the proximity of each carrier’s towers to the EV charging Station site. Based on these maps you can typically determine which carrier will have the best signal at a given location. We recommend printing all four carrier maps so that, once you’re on site, you can correctly orient yourself to the target tower and prevent a potential “overpower” situation.
Cell Carrier Frequency Bands by Zip Code
Once you’ve determined where the towers are, you need to determine what frequency bands the carriers use in a given location. Please note that carriers use different frequencies for different purposes in different locations so you always need to check.
www.wirelessadvisor.com does not give you specific frequencies being used in a given location, just the frequency band. In high density areas where cellular signal strength is typically good you may not need to know the specific frequencies used by each carrier, just the band and direction. This information is also helpful if you do need to know specific frequencies, to narrow your search on the FCC web site, coming up next.
Look up your specific local frequencies
Click “Geographic” under Specialized
Search then Search using the “address”
radio button ,limit to 7miles.
Limit frequency range to the below values:
700 MHz
728 to 757
850 MHz
869 to 894
1900 MHz
1930 to 1990
2110 to 2155
This site is hosted by the FCC and will tell you what specific frequencies are being used, by carrier, in a specific location. The link above, www.wilsonelectronics.com/fcc will re‐direct you to the FCC site which has a very long, confusing URL. This site is not as user friendly as the others but, after a few visits, it becomes easier to navigate. You’ll need to know the address and zip code of the survey site prior to starting your search. Once you reach the licensing home page, click on Geographic in the right hand column under Specialized Search. On the Search page click on the address button, enter your location address and limit the search to 7 miles. At the bottom of the search page you enter the specific frequency range you want to search for. Those ranges are listed in the Signal Meter’s user manual. On the results page, there may be dozens of license holders for that frequency range in that location. Typically you can identify the cellular carriers easily but, if not, you can typically figure out who the carrier is by clicking on the Licensee Call Sign and see who the license is billed to. For a pre‐installation survey when you haven’t determined which is the preferred carrier you may want to search for several/all the carriers frequencies at that location so that, once you’re on‐site, you can easily determine what carrier has the best signal.
Smart Phone Compass App
Finally, either a smart phone compass application or a real compass is a critical tool for the site survey and for proper orientation of the input antenna during installation. The directionality of the antenna and the RF signals themselves demands that the compass heading of the input antenna be accurate. In a weak signal scenario, a few degrees of compass heading can be the difference between success and failure.
There are a number of good apps available for Android and iOS, both free and paid. The one I use on my Android phone is called Field Compass, a free app that has proven to be reliable and easy to use.
Site Survey
1. Start with the Omni
Directional or Zero Gain
antenna on the meter.
2. Record signal strength for
the preferred carrier at the
(existing or proposed)
Charging Station location.
3. Look out for signals weaker
than -90dB which can cause
unreliable communications.
If this is a new installation it
means you will need a
booster. If it’s an existing
installation, it means
something has changed in
the local environment and
may require a booster to
Once you know the local frequencies for your preferred carrier, you can initiate a site survey. Begin your survey by recording relative signal strength at the existing or proposed Charging Station location using the Omni Directional (or Zero Gain) antenna that comes with the signal meter. Signal strength of ‐90dBm or weaker can cause unreliable communication and means you’ll need a booster for that location. If you’re seeing signal strength stronger than ‐90 dBm you shouldn’t need a booster to ensure good communications.
As a note to installers: In cases where the EV Charging Station is located indoors and/or underground, such as parking structures or garages, you will almost certainly need a booster. In these cases it is not uncommon to have satisfactory signal outdoors but virtually nothing inside due to the inability of RF signals to penetrate the structure. This scenario is relatively easy to remedy and will be covered in more detail in the Installation section of the training.
Directional Antenna and Meter
Directional Antenna Accessory Kit
Once you’ve determined that you need a booster, you need to determine what the actual signal strength is unimpeded by any obstructions. Connect the wide band antenna to the meter with the supplied cable and adaptors. A mast mount kit is supplied to use as a handle for the antenna. In this configuration, the meter becomes a directional signal finder, and can be used to determine actual signal strength for the preferred carrier and optimize input antenna placement. Get as high in or on the structure as possible and, using your compass, orient the directional antenna towards the target towers (determined on www.cellreception.com) , step through each applicable frequency band and note the signal strength readings for each band. The signal strength will determine which Wilson booster is most appropriate for that location.
This concludes the first of two training sessions. Please click on the link for Session Two when you are ready to proceed.
Choosing the Right Wilson Electronics Product

needs the most improvement.
Please read the complete installation instructions included with each system
Lets take a look at the individual components in a Wilson booster system. The input antenna we provide with our kits is called a wide band directional antenna. It is a log periodic antenna which is highly directional and has good isolation front to back and adds 7‐9dB of gain. It should be mounted on the side of the building oriented towards the target cellular tower if possible, and should be mounted as high as possible, typically on a mast that is secured to the structure. Antenna mounting hardware and mast material, aka steel tubing, is widely available on‐line or at your local building supply store.
The booster or amplifier comes in three different gain levels depending on how much boost is needed, the Pro 65, Pro 70 and Pro 70 Plus. Try to choose a place for the booster that is not too far from the outside antenna, generally within a 50 foot cable run, and does not get too hot, too cold or too damp. An electrical closet or rack room is ideal. The output antenna is a directional panel antenna which can cover three to five thousand square feet when adequate input signal is supplied. It’s high gain, (about 5‐7dB) and has a wide beam width which gives it very good coverage characteristics. Panel antennas can be mounted on the ceiling or wall, and both antennas include mounting hardware.

All PRO boosters come as a complete kit including all necessary parts for installation
Wilson Pro Series cellular signal boosters are five band 3G / 4G amplifier kits which are compatible with all carriers and technologies except Spark. Pro boosters are available in three gain levels, depending on how much coverage area you need, or how strong or weak the outside signal is. The three models are identical except for their max gain and dynamic range. All boosters are 100% self‐optimizing, and easy to install. They feature a power light that changes color to indicate operational state, accompanied by an LCD screen to show you what’s happening on each of its five channels.
The Pro 65 provides 65dB of gain, and is great for a smaller coverage area, or a location where the outside signal is very strong, for example ‐65 to ‐70 dBm, and you simply need to get the signal from outside to inside, such as in a parking structure. It would also be appropriate for an outdoor installation application where outside signal is inadequate due to a structure that is between the Charging Station and the target cell tower.
The Pro 70 more than doubles the power of the 65, and will provide increased coverage area or make up for less outside signal. It should be used in weaker signal applications where the actual signal strength is ‐85 to ‐90 dBm or lower.
The Pro 70 Plus has more dynamic range than the Pro 70, and still provides 70dB of gain. Because of its greater dynamic range, it is well suited for strong signal applications where the actual signal strength is ‐50 to ‐65 dBm or stronger. The Pro 70 Plus has an additional 12dBm of conducted downlink power for greater indoor coverage, even in “overload”
situations. The integrated power meter helps optimize antenna placement and orientation of the outside antenna.

Product Installation Best Practices
Product Installation Best Practices: In this section we’ll talk about installation best practices and product specific recommendations that will give you the best chance of a successful outcome. The booster system installation is fairly straightforward and will be successful if a few basic steps are followed every time.

Antenna installation is a critical element in a successful Wilson booster deployment. The directionality of the equipment and the signal itself needs to be understood so that, particularly in weak signal scenarios, maximum performance can be achieved.
The wide band directional antenna is generally thought of as the input or outside antenna. It is high gain, averaging about +9dBm, and is wide band, so it works very well with all cellular frequencies. The shape of it’s beam extends to about 45 degrees, so it is considered highly directional. Because of its directionality, it offers about 18 dBm of isolation front to back. This helps reduce the need for excessive physical separation from the output antenna, and allows the installer to tune out signals that are too strong. The input and output antenna should typically be separated by at least 50‐60 linear feet with as much vertical separation as possible. Insufficient physical separation can lead to a condition called “oscillation” which is a feedback loop between the two antennas which we’ll talk about in the troubleshooting section.
The panel or output antenna is a vertically polarized directional antenna, which has a much wider beam of 115 degrees giving it very good coverage area. The gain on the panel antenna averages about +6dB and the front to back isolation is about 8dB. When properly installed and supplied with signal, a panel antenna can cover up to 5000 sq. ft. in open air. To ensure best coverage, plan one panel antenna per 3000 to 4000 sq. ft. of coverage area required. The antenna can be mounted on the wall or ceiling or behind sheetrock or acoustical tiles. A flush mount kit is also available. The antenna comes with wall mounting hardware, and can be used indoors or outdoors.
One thing to remember about antennas, is that they all do the same thing, they send and receive information What sets them apart from one another are their characteristics One
Lightning and Weather
Lightning surge protection
Replaceable gas discharge element
Protects downstream equipment
50 or 75 ohm models
Low loss
Improperly sealed outside connector
A lightning surge protector is included with each Pro booster kit. The lightning surge protector is placed between the outside antenna and the Pro booster, and will shunt a high voltage discharge, like a lightning strike or downed power line to ground. The device has very low loss, and works with all cellular frequencies. Make sure to check your local code for required placement.
A common service problem is corroded connections which can cause the Pro booster not to work. Anytime you have a connection which is exposed to the elements, make sure to weather proof it. There are several good ways to weatherize an F connecter. One of the easiest is a product called “Temflex” by 3M. It comes in a roll like electric tape and is very easy to apply. 21
Amplifier Installation
Green – The booster is operating properly
Green/Red – Auto gain control is reducing gain
due to oscillation
Red – A red light indicates that the booster has
shut down on that frequency due to oscillation
(Increase antenna separation or isolation)
Green/Orange – Auto gain control is reducing
gain due to overload
Orange – The indicated channel is
experiencing overload due to close proximity of
a cell tower (Re-orient outside antenna away from
source of overload)
Other light combinations are possible. For a
complete list of possible error lights see the
installation guide included with the amplifier.
All Wilson Boosters feature automatic controls to protect
cellular networks from harm due to oscillation or overload
Once the amplifier has been secured in a cool, dry location connect the input and output coax cable and power up the unit. A diagnostic LED on the face of the amplifier will come on solid green if everything is working properly and the on‐board diagnostics have not detected any issues with it’s input or output signal. A complete explanation of the diagnostic LED, what it means and how to correct any problems will be covered in the next section.
Antenna and Amplifier Installation Best Practices
Always aim the Outside Antenna and Inside Antenna away from each other.
This helps maintain isolation between the antennas. Additional isolating materials may be necessary.
Vertical separation helps increase isolation.
Mount amplifier inside in a cool, dry location with adequate ventilation.
Cables included in kits have been optimized for best performance and comply
with FCC requirements. Keep new cable runs as short as possible to minimize
loss, while maintaining minimum cable loss values.
Nearby towers can cause overload, know all local signal strengths before
starting the installation.
If practical, do a soft installation of the equipment first.
Inside antennas can cover four to five thousand square feet when properly
installed and supplied with signal.
A quick recap of Antenna and Amplifier Installation Best Practices : Always aim the input Antenna and output Antenna away from each other and try to keep them separated by 50‐
60 feet. This helps maintain isolation between the antennas and prevents oscillation which can shut down the amplifier. Additional isolating materials may be necessary such as metallic radiant barrier, available at any home improvement store, placed behind the output antenna. Vertical separation also helps increase isolation.
Mount the amplifier inside in a cool, dry location with adequate ventilation.
Cables included in the kits have been optimized for best performance and comply with FCC requirements.

On-Board Diagnostics and Troubleshooting
On‐Board Diagnostics and Troubleshooting: In this section we’ll talk about Wilson amplifiers on‐board diagnostics capability, how to interpret diagnostic signals and how to fix the problems that the diagnostics have identified. This is the final section of the training and will be followed by a link to a short certification test.
Oscillation & Overload
Occasional installation issues
Oscillation – Occurs when inside antenna and outside antenna “talk” to each other
causing an RF loop, or feedback.
Solution: Increase separation of the antennas. Increasing isolation is the key and can be
achieved mechanically in some cases.
Overload – Caused by close proximity to a cell tower. The offending tower may be on
another network.
Solution: If working with a directional outside antenna, re-orienting the antenna may solve the
See install guide for complete instructions
All Wilson Boosters feature automatic controls to protect
cellular networks from harm due to oscillation or overload
There are two potential problems that can occur during installation. These issues are not common, but it’s good to be aware of any potential problems up front. The first, called Oscillation, can happen if the inside antenna and the outside antenna can “talk “ to each other, known as a feedback loop.. This issue is indicated by a red light on the booster and OSC / OFF showing on the LCD display of the booster. There are several lighting combinations possible on Pro boosters, but if you get a solid red light on the booster, you will need to separate and/or isolate your input and output antennas from one another. The second issue that can occur is called overload. Overload is too strong a signal coming into the outside antenna from the tower. This fault is indicated by a solid orange light on the amplifier, and is solved by pointing the outside antenna away from the source of the overload. Please read the instruction manual for a complete description of light combinations, what they mean and how to correct them.

operating at reduced gain due to
oscillation (feedback).
LCD Screen
Band Select Button
The Pro Series Amplifiers are 100% self optimizing and need no adjustment from the installer. If any oscillation or overload occurs which causes the booster to self adjust, the power light will change color, and an asterisk will blink in the upper right corner of the LCD screen. Cycle through the frequencies using the band select button to see what’s happening on each frequency.
Let’s review the possible warnings and what to do if you get one. A green light indicates the unit is powered, and operating at full gain. If coverage is good, no further action is required, and your installation is complete! An alternating orange to green light indicates proper operation, but at reduced gain due to overload. Recall that overload is too strong a signal coming from a nearby tower. If coverage area is adequate, you may leave the booster in this condition. If more coverage area is required, locate the direction of the overload signal, and aim the outside antenna away from that direction. This should cure the overload. In some cases, relocation of the outside antenna to a more sheltered position may be required. An alternating red to green light indicates proper operation at reduced gain due to oscillation, again, if coverage inside is adequate, you can leave the booster in this state. If more coverage area is required, simply move the inside and outside antenna farther apart, or add some type of mechanical shielding like radiant barrier liner to increase isolation. Contact Wilson Technical Support if you need more information about this approach. 26
Power/Indicator Light
Red indicator light:
The booster has shut down due
to extreme oscillation (feedback).
LCD Screen
Band Select Button
A solid red light indicates the booster has shut down due to extreme oscillation. In this case, you must take action, either separate or isolate the inside and outside antennas. Physical separation of 50‐60 feet is recommended. If that isn’t possible, mechanical separation using a metallic radiant barrier material on the back of the output antenna can help. This material is found at any home improvement warehouse store.
Power/Indicator Light
Orange indicator light:
The booster has shut down due
to extreme signal overload. (too
close to a cell tower).
LCD Screen
Band Select Button
A solid orange light indicates the booster has shut down due to extreme overload. In this case, you will need to re‐orient the input antenna, and possibly relocate it to a more sheltered location. Since the input antenna is highly directional, with a 45 degree field of view, re‐orienting it away from the source of overload by just a few degrees is typically enough to eliminate the overload situation without degrading the system performance.
Best Practices
Mount outside antenna on side of building where
strongest cell signal is found. Aim the antenna
away from the building to minimize oscillation
(red light). Additional isolating materials or
separation may be necessary
Keep cable runs as short as possible to minimize
loss, but never use less than the length provided
with the kit
Nearby towers can cause overload (orange light),
re-aiming the outside antenna can cure this
One inside antenna can cover four to five
thousand square feet.
Mount the amplifier in a cool dry place in a spot
where it has room to breathe. It does produce
some heat.
Lets review installation best practices, and of course, please read the installation manual completely before beginning your first install. Starting with the input antenna, find the side of the building closest to your target tower and mount the antenna as high as possible on that side of the building. Make sure the antenna is aimed away from the building to help minimize the possibility of oscillation.

Before you finalize your outside antenna placement, make sure you will not have an overload situation. Nearby towers of other carriers can cause overload because multiple all carriers operate on the same 5 bands. Pro boosters are wide band devices so an overload for one carrier can affect any carriers sharing that band. Remember, each panel antenna can cover up to a maximum of 5000 square feet. Coverage will be less in areas where interior walls prevent signal propagation or exterior signal strength is weak (‐90 dBm or worse).
