CELL-L3

4G BeiDou positioning badge

Direct 4G reporting with seamless indoor and outdoor positioning

• 47gTotal weight, lightweight to wear
• 10mBeiDou / GPS positioning accuracy (CEP50)¹
• IP67Dust and water protection; operating temperature −20 to 60 °C
• Approx. 1dayBattery life: alternating 8 h working and 16 h power saving²

1. ¹Satellite positioning accuracy is the nominal CEP50 value in an open area and is affected by weather, building obstructions and location. Lindos OS calculates indoor positions from 2.4 GHz beacon data.
2. ²Battery life is tested with default settings: working mode locates and reports once per minute, with more frequent 2.4 GHz scans; power-saving mode scans, locates and reports once per hour. Alternating 8 hours working and 16 hours power saving gives about 1 day; power-saving mode alone gives about 4.5 days. Actual battery life varies by use case.

CELL-L4

Helmet positioning tag

Attach to a safety helmet to keep personnel locations connected

• 6.7gTotal weight
• IP66Dust and water protection; ultrasonically sealed housing
• 3yearsBattery life with default broadcast settings¹
• -20~60°COperating temperature

1. ¹Default broadcasts: location at 0 dBm every 10 s; status at −8 dBm every 5 s. Changing location broadcasts to every 5 s gives about 2 years. Values are nominal; actual battery life depends on temperature and broadcast settings.

CELL-A1

Connectable asset tag

Track the location and movement of equipment, returnable assets and facilities.

• 3yearsBattery life with default broadcast settings¹
• 7.2mmHousing thickness; dimensions 56 × 34.5 mm
• 17gTotal weight
• 1sBroadcast interval after tamper detection²

1. ¹Default broadcasts: location at 0 dBm every 2 s; status at −8 dBm every 5 s; combined tamper frames at 0 dBm every 5 s. Values are nominal; actual performance depends on temperature and broadcast settings.
2. ²When the tamper switch is triggered, combined frames broadcast every 1 s for 30 s, then stop.

CELL-THL4

Long-range temperature and humidity sensor

Read locally on the LCD; receive reports when temperature limits are exceeded

• ±0.3°CTemperature accuracy from 0 to 30 °C¹
• Approx. 1kmLine-of-sight range in an open area²
• 100,000 recordsOn-device data storage
• -30~70°CTemperature measurement range

1. ¹Temperature accuracy: ±0.3 °C from 0 to 30 °C; ±0.5 °C across the rest of the measurement range.
2. ²Reference value for open, line-of-sight conditions at a maximum transmit power of 19 dBm. Actual coverage depends on antenna placement, obstructions, radio interference and network settings, and must be established by a site survey.

CELL-DML2

Wireless door sensor

An external magnetic probe reports door open/closed status over long distances

• 20mmMagnetic door detection distance
• 3yearsReference battery life with 10-minute reporting¹
• -40~85°COperating temperature
• 128bitsAES data encryption

1. ¹Reference conditions: one report every 10 minutes, medium data rate and an ambient temperature of 25 °C. Actual battery life varies with the detection cycle, door activity and operating environment.

GRID

Network backbone

Reliably carry site signals upstream and commands downstream

GRID-G4

4G cloud bridge receiver

Connect to power; multiple uplinks keep site data connected

• Approx. 400records/sScanning capacity per radio module¹
• 2.4WNormal operating power; peak 4.2 W²
• 3uplink typesAutomatic Ethernet / Wi-Fi / 4G failover³
• PoEPower over Ethernet (IEEE 802.3af) or 12 V DC

1. ¹Scanning capacity is per radio module: one scanning module is enabled by default, with multiple modules configurable. This is not the number of concurrently connected devices. Actual throughput depends on sensor broadcast settings, radio conditions and uplink capacity.
2. ²Normal operating power is 2.4 W; peak consumption during multi-protocol communication and high-performance operation is 4.2 W.
3. ³All networks must be configured before failover can operate. Priority is Ethernet, then Wi-Fi, then 4G. A 4G uplink requires a SIM card and mobile network coverage.

GRID-G4M

Outdoor mobile 4G receiver

Connect to vehicle power to keep assets visible in transit

• Approx. 100units2.4 GHz tags online simultaneously over a Cat.1 network¹
• 8–52VWide-input-voltage DC vehicle power
• IP67Protection rating; IK10 impact resistance²
• 15mGNSS satellite positioning accuracy³

1. ¹About 100 simultaneous 2.4 GHz tags on a 4G Cat.1 network is a nominal value. Actual capacity depends on tag broadcast intervals, reporting cycles and network conditions; it is not a system concurrency guarantee.
2. ²IP67 and IK10 are nominal protection ratings. The unit can be mounted outside the vehicle where needed to improve positioning and communication. Do not use it for extended periods above 60 °C.
3. ³Positioning accuracy depends on installation and deployment conditions. For installation inside a vehicle, avoid metal obstructions in front of the unit to improve satellite reception.

GRID-B2

Relay positioning anchor

Relay, positioning anchor and beacon in one: battery powered, with no wiring

• 5.5yearsReference life at default settings; up to 10 years with infrequent scanning¹
• 10.8AhReplaceable industrial lithium-thionyl chloride battery
• Up to 100unitsSensors forwarded by the relay²
• IP67Dust and water protection with no-wiring deployment

1. ¹Reference life assumes 25 °C ambient temperature, 0 dBm transmit power, a 2-second broadcast interval and a 1.2-second scan duration. Scanning every 30 seconds by default gives about 5.5 years; every minute about 8 years; every 2 minutes about 10 years. These estimates use laboratory power tests and theoretical calculations; actual life depends on environment, temperature and settings.
2. ²Relay scanning forwards identification data for up to 100 sensors. Data exceeding one packet is automatically split across broadcast packets. This figure is not receiver capacity or system concurrency.

Specifications are nominal; test conditions are given in the footnotes. Product form and feature configuration depend on the project delivery. Detailed sensor and receiver specifications are available after an initial discussion.
