GENERAL INFORMATION
Cellular Meter 2G/3G is a portable measurement instrument which
designed to assistance at deployment and maintenance of cellular repeaters
and other cellular equipment.
Cell Meter allows monitoring of the radiofrequencies within the main
cellular bands: EGSM 900, GSM 850, DCS 1800, PCS 1900, 3G 2100 (3GPP
Band I) and 3G 900 (3GPP Band VIII).
The device has connectors (holders) to install of up to 6 SIM-cards,
which allows working with all telecom operators by switching over SIM-cards,
which significantly saves time and drastically increases reliability of the device.
As a control and display unit for the device can be use any kind smart-
phones and tablet computers based on Android and Apple iOS operating
system (hereinafter referred to as OS), as well as Windows based personal
computers (hereinafter referred to as PCs), laptops and tablet computers can
be used via Wi-Fi or USB-host.
Wi-Fi allows operating with the device at a convenient distance and by
a local wireless network. For long-term radio monitoring from a Windows-
based PC the device provides charging and data connection by the USB-cable.
Nevertheless, in case of thunderstorm strongly recommended to use Wi-Fi
wireless connection, but charging from AC adapter.
If the USB-cable (or charger) connected before powering on the device,
then device will operate only by the USB, that indicated by the red blinking
LED. For Wi-Fi operation mode USB-cable (or charger) must be connected only
after power on of the device or re-connect the cable thereafter. In other
words, the device checks USB connection during powering on. If the cable is
not connected (or disconnected thereafter), then device will switch to the Wi-
Fi operating mode, which is indicated by the blue blinking LED. In order to
return the USB operating mode, just switch off the device; connect cable and

MAINTENANCE AND OPERATION
For proper operation of Cell Meter, make sure that RF connectors are in
good condition. Wipe them with a clear alcohol when clean necessary. Strongly
recommended to close connectors with safety caps for not only the
transportation, but also when not in use.
Periodically check the level of the accumulator battery during the
operation and recharge when necessary. The battery voltage and the
approximate percent of the change level indicated in the main menu or in the
headline of the operating modes of the software; it depends on the OS type and
version. Operation with a low-charged battery can cause of failures. Remember
that the accumulator’s capacity decreases at very low and very high
temperatures. Cell Meter switch off automatically when the battery discharged
below the minimum threshold or by timer after 10 minutes of idle.
Note: Yellow charging indicator will switched off when the battery is 95%
full. This indicate that quick cycle of charging (by high current) is finished.
Installation of SIM-Cards
Install inside the Cell Meter at least one SIM-card before start operation.
Can be installed up to 6 SIM-cards in order to analyze all available mobile
network operators (MNO) by switching the SIM-cards in the program. The "all
channels scanning" function will indicate levels of all channels independently of
SIM-card selected in software; however, at least one SIM-card is required for
normal operation of the Cell Meter. If no SIM-card in the selected holder, then
"all channels scanning" and some other functions become inactive in software.
To install SIM-cards you have to partially disassembly device (picture 1).
Screw out four front bezel screws (2) and remove the front bezel (1). Pull out
the upper aluminum lid (9) in towards to the just removed front bezel (it might
require muscle force). Make sure that Cell Meter is off before start working
with SIM-cards. Place the SIM-cards into connectors (10) in any convenient
order. Labeling of the connectors corresponds to numeration in the software.
Switch on the device without lid and bezel and check device operation with all
the installed SIM-cards.
Note: PIN-code must we deactivated!

address set by the local network router. For further software operation with
the device find out its IP address and enter it in the “CELLMETER” software
settings. Operation of the device cannot guaranteed for all types of routers.
We tested operation with such popular routers as ZyXEL, D-Link, TP-Link,
OpenWRT.
Cell Meter in “AP+STA mode”indicates the local network connection by
blue blinking twice a second. In this case, connect control gadget to local
network too and configure Cell Meter software to the local network address.
Data transmission activity indicated by frequent blinking in time with the data.
Connection failure or disconnection indicated once a second.
Cell Meter in “AP mode” indicates creation of “CELLMETER” network by
blue color once a second and frequent blinking in time with the data.
You can return to “AP mode” via the WEB interface or reset of the
device’s Wi-Fi module parameters to the initial status. For this purpose, you
can use “DFLT” control point near Micro USB connector below the front lid of
the device (pos. 12 in pic. 1). For reset switch on the device and short “DFLT”
control point for 2-3 seconds together with the minus common circuit, for

SHORT SOFTWARE DESCRIPTION
Our software regularly upgraded, so this section describes only its
most important parameters. New software versions are available on Play
Market™ and App Store™, as well as on our Web site http://cell.sdelab.ru/.
Basic Software Functions:
I. Scanning of all channels.
This function simultaneously scans all frequency channels (voice and
control) of all operators and displaying it graphically. This allows to setup
antenna in such direction so that peak signals of all operators will an
approximately equal level. For better displaying, you have to tune bands of
channel numbers dedicated for local MNO’s and colors in menu settings.
II. Scanning of all control channels in the graphical form.
This function is similar to I (above), but it only displays signal levels of
control channels of all MNO’s. This contributes higher speed of the device,
but reduces stability. The device can start to work with only one MNO,
which is dominating in signal level. Just restart the function in such cases.
III. Scanning of all control channels in the table form.
This function is similar to II (above), but information is in digital values of
channel numbers and their levels in the table form.
IV. Scanning of service and neighbor stations of SIM selected MNO.
This function displays information of the levels and channel numbers of
service and neighbor stations of the selected SIM card operator. Besides, it

gives a lot of additional information on the system. In this mode, the device
is trying to register in the network of the selected operator. This function is
similar to service monitor mode of cellular phones, but data displayed in a
more convenient form and table. Some columns of table can be set hidden
in menu settings.
V. Measuring of isolation (insertion loss, attenuation).
This function finds a free frequency channel at the INPUT connector and
then measures the level of the own signal generated at the OUTPUT
connector. This allows to measure attenuation from 0 dB to more than 110
dB, which is enough to determine the level of isolation between donor and
service antennas for repeaters. Use an external directional coupler if
required to check RF matching (VSWR) of cable or other passive
components (antennas, splitters, combiners, etc.). It will be difference
(matching value) between forwarded and reflected levels at the coupling
connector. Bigger difference means better matching. Preferably, matching
value is higher than 10 dB, i.e. ratio VSWR < 2.
VI. Measuring of the signal quality.
This mode displays the level of the received signal in time by a diagram
during a call to an answering machine phone number. While the
connection is set, the Base Station measures the level of errors (BER) and
sends it to device to display. Upon expiration of the answering machine
time and drop call, the device performs redial. Enter a free of charge
phone numbers of answering machines for all installed SIM-cards in
software settings.
Caution! Please do not use phone numbers where people operated!
Main features of Windows based software.
