We've all been in a crowded room trying to carry on a conversation with someone.

Without fail, every time you raise your voice so that the other person can hear you, everyone else raises their voice accordingly and the noise level in the room is only magnified and made worse.

Cellular Networks are effected by the same type of noise problems.

QUATRA Active DAS Hybrid Signal Boosters work by isolating individual channels for each Carrier.  Its the same as hearing only one person in a crowd.

Their ability to isolate and remove all of the other surrounding noise authorizes them to boost signals at up to max 100 dB Gain to create a stronger and higher quality signal for your cell phone.

Wideband Passive DAS Signal Boosters on the other hand cannot differentiate channels on any band and must therefore boost all RF signals within each band. Its like amplifying noise from the entire crowd.

The resultant effect is that these systems must be regulated to no more than max 70 dB Gain so as not to harm the Cellular Networks.

How Wideband Passive DAS

Signal Boosters work

Cell Signals

Cell Phones and NB-IoT devices require strong radio frequency (RF) signals for voice and data communications.  In order to support the billions of cellular and IoT devices in use, Wireless Carriers simultaneously utilize numerous channels across multiple Bands/Frequencies, each with their own bandwidth and building penetration characteristics.

Open Air Path Loss

Signal strength gets weaker over distance, especially on higher frequencies like 2500 MHz, 1900 MHz PCS and 2100 MHz AWS, so as bandwidth/speed increases, the signal strength/penetration decreases.

Material Obstructions

Upon reaching your building, RF signal strength is further decreased by walls, doors and other material obstructions.  The greater the density of the floor plan, the greater likelihood of weaker signals.

In-Building Walk Test

Performing this test is the most reliable way to determine the RAW signal strength for your Cell Phone and NB-IoT devices, otherwise known as Reference Signal Received Power (RSRP)

Visualizing this signal strength information is the first step toward better wireless connectivity.

Wireless Map

The end result of our In-building Walk Test is a visual guide into the wireless signal environment within your building.  The wireless map shows areas of strong and weak coverage for all Wireless Carriers across all bands, frequencies and channels that they are operating on within your area.

Using this information, we are able to optimize a cost effective signal booster solution design layout saving time and money by knowing exactly which areas of your building need to be boosted.

QUATRA is authorized by the FCC and Wireless Carriers to boost up to max 100dB Gain per Channel.

With advanced, channel select filtering algorithms, each Carrier Band and Channel are individually optimized regardless of tower location. This means that each Carrier regardless of tower location will enjoy signal strengths that are up to max 100dB Gain, resulting in much stronger in-building coverage across all Bands.

Passive DAS Signal Boosters are limited by the FCC and Wireless Carriers to up to max 70 dB Gain per Band.

With no ability to distinguish between Carrier channels, this technology treats all Carriers equally per Band and is Band limited in the amount of Gain output for each Band. This means that weaker Carriers with towers that are further away and on the same Band as stronger Carrier towers that are closer will not realize the max 70 dB Gain which will result in a lower overall signal strength gain for the Carrier that is further away.

The QUATRA 30 dB Gain difference allows it to operate with an exceptionally low outdoor donor signal strength and then creates equalized in-building signal boost for all bands, frequencies and channels with a larger coverage footprint and signal strengths that are

up to 1,000x stronger .

Passive DAS systems create unequal coverage footprints and weaker signal gains.

For cell phones and NB-IoT devices to work properly,

you should have a strong cellular signal.

If you have a weak signal, some of the things that need to be considered are distance from the tower and material obstructions.

Cell Phone Bars

The simple truth is that there are no industry standards as to what bars on a cell phone mean. Therefore, mobile phone manufacturers and operators are free to create their own algorithms to calculate things like signal strength, signal-to-noise ratio, and channel loading among other things.
