The integrated BLE module allows the device to communicate with the PureBeacon (home unit) Bluetooth device while the GNSS module is used for location positioning using sate llites. The built in LTE cellular module is used for communication with PureMonitor. The PureOne device comes with a portable charger, that allows seamless and convenient charging. Both the charger and the PureOne device are equipped with LED interface that indicates the different states and modes of the devices. Turning the PureOne on To turn on the PureOne, simply connect the charger to the device. Once the device detects that the charger is attached, the PureOne will automatically be turned on. Allocation of the PureOne & the PureBeacon devices in PureMonitor Once offender profile was created in the system the device can be assigned to it. The allocation of the device is done via PureMonitor, in the following steps:

1 . On the Offenders Equipment Tab, click Allocate Device 2. Search for the PureOne serial number or select the PureOne from the list of devices then click Allocate 3. If a PureBeacon device is needed repeat step 2 i.e. select a PureBeacon home unit by serial number and click Allocate 4. The PureOne and PureBeacon devices are now added to the Offenders Equipment list and is ready for activation.

Monitoring start (a ctivation) in PureMonitor Once the monitoring device/s are allocated the main device can be activated in order to enroll and start monitoring. Click Activate button colored in green to send activation request to the PureOne. Once clicked, the information section soon will become available and devices status and recent events will be displayed. PureOne Monitoring Page 3 of 19 SuperCom Confidential Information Monitoring end (unallocation) in PureMonitor To finish the monitoring devices needs to be removed from offender in PureMonitor. The unallocation of the device/s is done in the following steps:

1. If the offender has any PureBeacon(s) allocated to them, the device must be unallocated from the offender prior to the unallocation of the PureOne device. 2. A device can be unallocated by going to the Offenders Equipment Tab, clicking on a devices Settings button and then clicking on the red Unallocate button:

3. Once the device confirms the unallocation request was received it will be removed from the offender and will not appear under their Equipment tab.

- Analyze and demonstrate the cellular and BLE Tx duty factor.

- Describe all reasonable and infrequent use cases.

Show how the design inherently provides protection from alterations of the maximum duty factor that was considered for compliance purposes. Device details Product:

Manufacturer:

Model:

Hardware Version:

FCC ID:

PureOne SuperCom LTD PureOne 3.0 2BAX3PRFPUREONE30 Device Tx Data Analysis Cellular Data Tx Flow

- Communication interval o Infrequent: every 60 minutes, usually when at home. o Frequent: every 10 minutes, usually when outside home.

- Communication session flow:

o Authentication and security o Data exchange o Session termination Data payload analysis:

Data payload is up to 2060 bytes per session, according to the following analysis:

o Authentication and security 600 bytes TLS/SSL negotiation: 200 bytes HTTP headers and structure: 180 bytes Protocol overhead data: 100 bytes Authentication net payload: 120 bytes o Data exchange 1100 bytes Security overhead 80 bytes HTTP headers and structure: 180 bytes Other overhead data: 100 bytes Data items size: 640 byes Single data item size: 32 bytes Protocol overhead data: 32 bytes Number of data items: 10 o Session termination 360 bytes Security overhead 80 bytes HTTP headers and structure: 180 bytes Protocol overhead data: 40 bytes Termination net payload: 60 bytes Standard Active Transmission Time BLE Tx schematics

2060 bytes payload in bits o 2060 X 8 = 16,480

- Data rate: assuming 5 Mbps (using LTE network connection)

- Calculation:

o 16,480 / 5 = 3.296 milliseconds The active transmission time is a time slot of 10 minutes is 3.296 milliseconds. Duty Cycle = (3.296 milliseconds / 600,000 milliseconds) * 100 = 0.05493%

The standard typical duty cycle is: 0.05493%

Description of reasonable and infrequent cases - Cellular There are 3 use cases:

1. Standard reporting. a. Device is active, not at home, communications is every 10 minutes. b. Duty cycle is 0.05493%

2. Infrequent reporting. a. Device is active, at home or static position/location, communications is every 60 minutes. b. Duty cycle is 0.00915%

3. Alarm reporting. a. A special case where a single alarm/data should be immediately sent. b. Maximum allowed alarms per day: 20 alarms Duty cycle at worst case scenario:

Assumptions:

Standard reporting mode is active all the time. o Communication is every 10 minutes. o Payload per session: 2060 bytes o Daily payload:

1440 minutes / 10 minutes X 2060 bytes Daily payload: 296,640 bytes

- Device is triggering 20 alarms per day. o Each alarm payload: 2060 bytes o Daily alarms payload: 2060 * 20 = 41,200 bytes Total daily payload: 296,640 + 41,200 = 337,840 bytes

Daily Payload in bits: 337,840 * 8 = 2,702,720 bits Tx time, assuming data rate of 5Mbps: 2,702,720 / 5 = 540,544 milliseconds Daily Duty Cycle = (540,544 milliseconds / 86,400,000 daily milliseconds) * 100 = 0.6267%

The maximum daily Tx duty cycle is 0.6267%. Bluetooth duty cycle analysis The PureOne device uses a Bluetooth low energy certified module. The device is set up to transmit status data every 5 seconds. The protocol is Advertising (broadcast) under GAP profile. Protocol characteristics:

- Data rate: 1 Mbps

Interval: 5 seconds

- Channels: All 3 channels used (channels: 37,38,39)

Payload: 39 bytes Standard Active Transmission Time Payload in bits: 39 (bytes) * 8 = 312 bits Daily packets: 86400 / 5 = 17,280 All 3 BLE channels: 17,280 * 3 = 51,840 51,880 / 1 (Mbps) = 51.88 milliseconds Duty cycle: 51.88 / 86,400,000 = 0.00006 %

The BLE duty cycle is 0.00006 %

Description of reasonable and infrequent cases The BLE advertising protocol uses a random time before/after each 5 seconds Tx interval. The average of 5 seconds interval is still being kept. System design to protect from duty cycle alterations. Standard design The PureOne device is a hardware-based device. The hardware was designed, reviewed, implemented, and manufactured using standard design tool and by professional engineers. During manufacturing, each single device is being tested and documented for quality control. The radio hardware component are certified. During development process, intensive QA and external Labs are used for verifications. Design to meet and keep requirements:

To meet duty cycle requirements, and keep up with them:

- Device has a precise real time clock for timing. o Time is constantly being verified against a server to avoid any drift.

- Device has flash and eeprom memory to keep track of all communication intervals and data payload history.

- RF modules are certified and by know vendors.

Product is being tested at RF labs. Product is reporting its Tx statistics for analysis and record keeping.

Proj. nr: 0490, 502, 561 & 582 Rel.:r3 Date: 28.09.20 2.2 WCDMA TX Tune Up WCDMA Tx tune up is being done with QCOMM tool and performed within three steps:

Tx linearization & Freq Compensation Composite Tx/Rx vs frequency Tx Limiting & Freq Compensation 2.2.1 Tx linearization & Freq Compensation The unit transmits in a reference channel (mid) and perform TX sweep while searching for the correct HDET value at each PDM step and generate PDM vs Power tables for the 2 PA gain states (1, 0). After completing calibration on the reference channel frequency the compensation being done on 3 channels across the band. 2.2.2 WCDMA composite Tx/Rx vs frequency calibration procedure WCDMA composite Tx/Rx vs frequency calibration is using QCOMM GUI. Composite Tx/Rx calibration is an alternative to the serial Tx and serial Rx calibration procedures. Composite Tx/Rx calibration is a fast and efficient calibration procedure that uses the Tx/Rx vs frequency sweep and perform Tx and Rx measurements in parallel. Overview of Tx/Rx vs frequency sweep In the Tx/Rx vs frequency sweep measurement, the phone transmits a predefined Tx power sequence and the test equipment measures Tx power. Simultaneously, the test equipment generates a predefined Rx power sequence and the phone performs Rx measurements. Key features of the measurement are:

>> The mobiles Tx power provides a rising edge for triggering the start of the first sequence.

>> Changes in mobile Tx power and mobile Rx power and Tx and Rx measurements are synchronized to segment boundaries.

>> The sweep is composed of a maximum of 3 sequences typically corresponding to the 3 RF calibration channel frequencies.

>> The test equipment will return results for Tx power measurements and the mobile will return results for Rx measurements along with a list of HDET values. 2.2.3 Tx Limiting & Freq Compensation Once values are set for the reference channel in 2 gain states. Compensation for all 3 channels at 2 PA states being done accordingly. 2.2.4 Range of operating RF Power for WCDMA The LE910Cx families support 7 WCDMA Bands The nominal power levels and tolerances are indicated in the following table:

Proj. nr: 0490, 502, 561 & 582 Rel.:r3 Date: 28.09.20 TECHNICAL NOTE 2.3 GSM TX Tune Up GSM calibration starts with KVCO calibration for all bands in order to insure the corrected VCO slope and good PLL operation. The TX calibration includes the following sections for all GSM bands:

>> Polar calibration

>> Timing delay calibration 2.3.1 Polar calibration Polar calibration is used for both GSM and EDGE. The unit perform TX sweep for 32 RGI values at 2 gain states (1,0) & three channels (Low, mid & high). The AM-to-AM and AM-to-PM characteristics of the PA being measured by the external equipment. The measurement results from the external equipment being processed before they are loaded into the module. The module then uses the AM-to-AM and AM-to-PM tables to provide the appropriate pre-distortion to the PA. Calibration is done at high, mid and low frequency channels, and values are interpolated for any frequency in between. The AM component being reinserted back after the amplification stage to restore the modulation to its original form. 2.3.2 Timing delay calibration Existence of two separate waveform paths through the device could lead to different signal delays on the phase path and envelope path, and could affect the waveform quality. The best-case delay is determined by finding the delay value that results in the lowest ORFS due to modulation measurement at +400 kHz and -400 kHz. The ORFS due to modulation value tied to each delay is the worse one of +400 kHz and -400 kHz offset. 2.3.3 Range of operating RF Power for GSM The LE920 supports 4 GSM Bands The nominal power levels and tolerances are indicated in the following table:
