FAQ

TECHNOLOGY:

How Far From The Meter Can The Phone Be And Still Work?

The meter utilizes Bluetooth technology to communicate with the handset and app. The standard operational distance is between 30-50 feet.

Can More Than One Person Use/Share A Meter?

Yes. A single meter can be used by multiple users. Each user simply must download the Cell LinQ app from the Google Play store or from Apple’s App Store.

Can More Than One Person Use/Share A Meter?

Yes. A single meter can be used By multiple users. Each user simply must download the Cell LinQ app from the Google Play store or from Apple’s App Store.

FUNCTIONALITY:

What happens when the scan button is pressed?

The app will ensure a Bluetooth connection to the meter is working - if not, you will be prompted to pair your device with the meter. The meter will scan each channel for cell activity. If found it will send the appropriate information to the app for display.

What Data Is Collected When A Scan Is Performed?

3G: location, carrier, radio type, RSSI, channel frequency, mcc, mnc, cellid, lac, RSCP, Ec/Io

4G: location, carrier, radio type, RSSI, channel frequency, mcc, mnc, cellid, tac, RSRP, RSRQ

What happens when a new scan is performed?

Each time a scan is performed, all previous scan data is cleared. Once you complete a scan, you have the option of storing the scan information before moving on to the next scan.

Does The Cell LinQ Meter Utilize A Database To Gather Information?

We use a database to correlate carrier, radio type, and location with a cellid returned from the cell site.

What Does 'Unknown' Mean In The Carrier Column?

The carrier and location do not exist in the cell Id database for this particular cellid. If the cell Id is new, it may take a few weeks for the database to be updated with the new information.

What If I Want To Save The Scan Data Before Performing A New Scan?

Easy! You can save the scan data to a new project you create, or you can recall an existing project and add the scan information to the project.

Why Would I See Groups (or clusters) Of Towers In Close Proximity On The Map View?

Cell towers often utilize multiple antenna arrays to create a 360 degree coverage area. Each antenna will have a unique ID. If a scan is performed in a location where the coverage area overlaps with multiple antennas on a tower, the app may display data from more than one antenna off the same tower. Multiple tower pins would be visible in the scan results. These pins may be displayed in close proximity to each other on the map.

What Does Excellent, Good, Fair And Poor Mean?

Signal quality is not calculated but rather directly measured from the beacons received from the cell site.

Can I Export Scan Results?

Yes, the app will export a CSV file containing all scan information for a given customer / project.

Why Are There Carrier Specific Buttons At The Top Of The App?

You can filter specific carriers by simply toggling on or off each individual carrier. The blue light within each button indicates the carrier is active.

Will It Shorten The Scan Time By Turning Carrier(s) Off?

No. When a scan is performed, all available data is gathered by the meter. The carrier filters are a function of the app and therefore, does not save scan time.

How Long Does It Take To Complete A Single Scan And Will The Scan Time Always Be The Same?

A single scan will take approximately 90 seconds. This time may vary slightly as the meter scans each channel in each frequency band and waits for a beacon from any cells on that channel. If there is no cell active on that channel, we must wait approximately 2X the beacon interval to make sure we do not miss a beacon before moving to the next channel. Variances to complete a scan are likely due to the how fast the beacons are returned when active cells are found.

What Frequency Bands Does The Meter Scan?

BAND / TECHNOLOGY

B2 / LTE FDD

B4 / LTE FDD

B5 / LTE FDD

B12 / LTE FDD

B13 / LTE FDD

B2 / WCDMA FDD

B5 / WCDMA FDD

Does The Meter Support Public Safety Bands?

Not at this time. We are reviewing options to add band B14.

Why No Sprint Towers?

Although our current app has provisions for Sprint, the current bands supported are B2 (excluding G block), B4, B5, B12,B13 and B17. Sprint's 4G network uses LTE technology in bands 25, 26, and 41. Band 25 includes Sprint's original PCS spectrum, plus the newer G block of the PCS band.

Why Do I Get A Different Number Of Towers When I Run The Same Scan In The Same Place?

In some instances, taking multiple scans from the same location can result in varying results. This is mostly due to changing tower strengths and capacity.
