How to Extend Battery Life in Industrial IoT Devices with Sub-1GHz Wireless

Introduction: Why Extending Battery Life Matters in Industrial IoT

Industrial IoT deployments face a fundamental challenge: devices must operate reliably for years with minimal maintenance. Whether monitoring energy consumption in remote substations, tracking equipment health in sprawling manufacturing facilities, or reading utility meters across distributed networks, replacing batteries frequently is economically prohibitive and operationally disruptive.

Traditional wireless solutions consume excessive power during both active transmission and standby periods. A device that drains even 10 mA in idle mode will exhaust an AA battery in weeks, not years. This power budget constraint forces engineers to choose between frequent maintenance, larger batteries (increasing cost and form factor), or accepting shorter deployment windows.

Sub-1GHz wireless transceivers fundamentally change this equation. These devices operate below 1 GHz (typically 433 MHz, 868 MHz, or 915 MHz in ISM bands), where radio propagation characteristics enable longer range with lower transmit power. Combined with intelligent sleep architectures and efficient packet handling, sub-1GHz solutions deliver years of continuous operation from standard batteries transforming what was previously a maintenance burden into a reliable, autonomous system.

The HopeRF CMT2300H exemplifies this design philosophy. Purpose-built for industrial monitoring applications, this ultra-low power sub-1GHz RF transceiver achieves what traditional solutions cannot: device lifespans measured in years rather than months, without compromising range, data rate, or reliability.

Understanding Sub-1GHz Wireless: Why Lower Frequencies Equal Longer Battery Life

Sub-1GHz wireless operates fundamentally differently from higher-frequency bands like 2.4 GHz Wi-Fi or 5G. Lower frequencies propagate further through obstacles (walls, vegetation, soil) with less path loss. This means devices can communicate over greater distances whilst using lower transmit power - the primary consumer of battery energy.

Compare two scenarios: A 2.4 GHz device transmitting 20 dBm to reach 100 metres must drain significantly more current than a sub-1GHz device achieving the same range at 10 dBm. The difference compounds across thousands of transmissions. Over a device's operational lifetime, this translates to months or even years of additional battery life.

Sub-1GHz also enables duty cycle operation. Industrial sensors typically transmit brief status updates infrequently, taking a meter reading say once per hour, a temperature sample every 30 minutes, an alarm only when triggered. Sub-1GHz transceivers excel at this pattern: they sleep for extended periods at nano-ampere current levels, then wake briefly to transmit. The CMT2300H achieves 300 nanoamps in sleep mode, low enough that a single AA battery loses more charge through self-discharge than the transceiver consumes over months of standby.

CMT2300H Architecture: How Ultra-Low Power Design Works

The CMT2300H achieves its exceptional power efficiency through multiple integrated mechanisms:

Sleep Current Architecture The transceiver operates in multiple power states. In sleep mode, all RF circuitry powers down, only a 32 kHz oscillator remains active for wake timing. This enables 300 nA current consumption (duty cycle off) or 800 nA with the sleep timer active. For comparison, many wireless modules consume milliamps perpetually. A device sleeping for 99 per cent of its operational life consumes 99 per cent less energy than always-on alternatives.

Intelligent Packet Handling The CMT2300H integrates a packet handler that manages preamble detection, synchronisation word recognition, and CRC validation entirely in hardware. Rather than waking the host MCU for every received signal, the transceiver filters noise and false triggers. Only valid packets trigger interrupts, allowing the MCU to remain asleep during false alarms. This "smart filtering" eliminates wasted wake cycles that plague simpler transceivers.

Fast Frequency Settling Frequency tuning consumes measurable power. The CMT2300H settles frequency in 150 microseconds and supports fast frequency hopping via simple register writes. Devices can rapidly switch between channels without re-tuning from scratch, enabling efficient channel-hopping protocols that improve reliability without proportionally increasing power consumption.

Configurable Power Modes The transceiver supports high-power mode (8.5 mA receive) and low-power mode (7.2 mA receive) for the same sensitivity settings. Applications can trade marginal sensitivity loss for meaningful current reduction in noise-rich environments, or maintain maximum sensitivity where weak signals matter. This flexibility allows engineers to optimise for their specific scenario rather than accepting one-size-fits-all defaults.

Technical Specifications: The Numbers Behind Battery Life

Understanding the CMT2300H's technical profile illuminates why it delivers extended battery life:

Parameter	Value	Benefit for Battery Life
Sleep Current	300 nA (off) / 800 nA (timer on)	Minimal standby drain over extended idle periods
RX Current	7.2–8.5 mA @ 433 MHz (mode-dependent)	Efficient listening - low power to stay aware
TX Current	23 mA @ 13 dBm / 72 mA @ 20 dBm	Scalable transmit power matches range requirement
Sensitivity	-121 dBm @ 2.0 kbps (433 MHz)	Superior weak-signal detection; lower transmit power needed for reliable links
Frequency Range	127–1020 MHz (multi-band capable)	ISM band operation; no licensing; global deployment options
Data Rate	0.5–300 kbps	Lower rates (2 kbps) consume less energy per bit transmitted
Settling Time	150 µs (frequency) / 350 µs (from standby)	Quick activation minimises wake-time energy expenditure
FIFO Buffer	64 bytes (merged mode)	Packet batching reduces transmission frequency
Operating Voltage	1.8–3.6 V	Operates across full battery discharge curve; extends usable battery capacity

The combination matters more than any single specification. A transceiver with excellent sensitivity but poor sleep characteristics still drains batteries. The CMT2300H optimises across the full operational profile: sleep, wake, transmit, receive - creating a coherent low-power system.

Real-World Applications: Where Sub-1GHz Battery Life Matters Most

Smart Utility Metering Utility companies deploy millions of water, gas, and electricity meters across service territories. Manual meter reading requires field technician visits which is costly and labour-intensive. Sub-1GHz wireless enables remote meter reading (AMR) and advanced metering infrastructure (AMI). A CMT2300H powered meter can transmit readings hourly for 10+ years on battery alone, eliminating frequent service calls. The investment in wireless infrastructure pays for itself through labour savings within months.

Industrial Equipment Monitoring Manufacturing facilities deploy wireless vibration sensors on rotating machinery to detect bearing wear before catastrophic failure. Traditional wired sensors require costly infrastructure; wireless sensors eliminate cabling but introduce battery constraints. Sub-1GHz transceivers enable sensors to survive the equipment's operational life on a single battery, eliminating maintenance and enabling predictive maintenance programmes that prevent unplanned downtime.

Building Automation and HVAC Wireless temperature, humidity, and occupancy sensors optimise heating and cooling across large buildings. Low-power sub-1GHz operation allows sensors to operate for years in hard-to-access ceiling spaces and walls. The CMT2300H's efficient packet mode means a sensor transmitting status every 10 minutes consumes far less energy than always-on alternatives, extending battery life from months to years.

Remote Environmental Monitoring Pipeline monitoring, wildlife tracking, air quality stations, and seismic sensors deployed across remote territories benefit from years of autonomous operation. Field teams can install networks and leave them unattended, with maintenance visits scheduled only after multi-year intervals when batteries actually need replacement rather than preventive cycles based on conservative assumptions.

Wireless Security and Access Control Door locks, motion sensors, and alarm transmitters often operate in locations where wired power is impractical. Sub-1GHz wireless with ultra-low power consumption enables security systems to function reliably across entire facilities without power conditioning infrastructure, reducing installation cost and complexity.

Why the CMT2300H Outperforms Alternatives for Battery-Constrained IoT

Several design choices set the CMT2300H apart from competing transceivers:

Integrated Packet Handler Reduces MCU Wake Cycles Many transceivers require the host microcontroller to wake and assess every signal. The CMT2300H's integrated packet handler performs preamble detection, synchronisation, and CRC checking in hardware. Invalid packets don't wake the MCU. For a device receiving constant ambient noise, this architectural difference translates to significantly fewer wake cycles and corresponding power savings.

Three Clock Data Recovery (CDR) Modes Different applications have different accuracy requirements. The CMT2300H offers counting mode (highest accuracy, requires precise clocks), tracing mode (automatic symbol rate correction, tolerates clock errors up to 15.6 per cent), and Manchester mode (specialised decoding). This flexibility allows engineers to relax crystal tolerances and reduce cost without sacrificing reliability enabling cheaper, simpler designs.

Configurable Sensitivity and Power Trade-offs Not all applications need maximum sensitivity. The CMT2300H allows users to trade receiver gain against power consumption. In high-noise environments, reduced gain still achieves required sensitivity whilst consuming less current. This flexibility permits optimisation for the specific deployment scenario rather than accepting worst-case power budgets.

Frequency Agility Without Tuning Overhead The CMT2300H supports rapid frequency hopping via simple register writes. Channel switching requires 150 microseconds and minimal energy. This enables frequency-diversity protocols transmitting on multiple channels to improve reliability without proportional power increases. Competing solutions requiring full PLL re-tuning consume more energy per channel switch, making hopping impractical.

Wide Voltage Range Operation The CMT2300H operates from 1.8 to 3.6 volts. This means devices can utilise batteries across their full discharge curve rather than stopping at 2.0 V. A two-AA battery system remains operable down to 1.8 V, extending effective capacity by 15–20 per cent compared to solutions requiring 3.0 V minimum.

Design Considerations: Optimising Battery Life in Your Application

Selecting a low-power transceiver is necessary but insufficient for extended battery life. System-level design decisions amplify or negate the hardware's inherent efficiency:

Data Rate Selection Lower data rates consume less energy per bit transmitted. The CMT2300H supports rates as low as 0.5 kbps. For applications where latency isn't critical, e.g. utility meters or environmental sensors, lower rates dramatically reduce power consumption. Transmitting a 100-byte meter reading at 2 kbps instead of 50 kbps reduces transmission time and energy by 25×.

Transmission Power Optimisation Transmit current scales dramatically with output power. At 13 dBm, the CMT2300H consumes 23 mA; at 20 dBm, 72 mA. Most IoT applications don't need maximum power. Calculate actual path loss for your deployment. If devices operate within 1 km in urban environments, 10 dBm often suffices. Using the minimum power necessary for reliable communication reduces transmit current proportionally.

Duty Cycle Design System-level duty cycle matters more than any individual specification. A device that transmits every hour for 100 milliseconds cycles at 0.01 per cent active time. Its average current consumption is:

• Sleep current × 0.9999 + Active current × 0.0001

Even with 8 mA receive current, if devices sleep 99.99 per cent of the time, sleep current dominates the power budget. The CMT2300H's 300 nA sleep specification becomes the binding constraint enabling multi-year battery life.

Packet Structure and Overhead The CMT2300H supports variable-length packets with flexible preambles. Minimising packet size reduces transmission time and energy. A 50-byte packet transmits in half the time of a 100-byte packet, reducing transmit energy proportionally. Design packet structures that contain only essential data; eliminate redundancy.

Antenna and Impedance Matching RF efficiency depends on proper antenna impedance matching and layout. Poor matching wastes transmit power as heat rather than radiation. The CMT2300H provides direct SMA connection or integrated matching networks. Professional antenna design and PCB layout can improve real-world range by 30–50 per cent compared to amateur implementations, reducing transmit power requirements and extending battery life.

Technical Specifications Deep Dive: CMT2300H Detailed Performance

Receiver Performance

The CMT2300H achieves remarkable sensitivity across sub-1GHz bands:

Frequency	Data Rate	Sensitivity	Power Mode
433 MHz	2.0 kbps	-121 dBm	High
433 MHz	10 kbps	-116 dBm	High
433 MHz	50 kbps	-111 dBm	High
433 MHz	300 kbps	-103 dBm	High
868 MHz	2.0 kbps	-119 dBm	High
868 MHz	10 kbps	-113 dBm	High
915 MHz	2.0 kbps	-117 dBm	High

This sensitivity enables the critical battery-saving feature: weak-signal reception at low transmit power. A distant device can achieve reliable links using 10 dBm (rather than maximum 20 dBm) because the receiver detects -121 dBm signals. Across an IoT network, lower transmit power on thousands of devices compounds to massive energy savings.

Advanced Signal Detection

The CMT2300H includes three sophisticated signal detection mechanisms:

Automatic Frequency Control (AFC) Crystal oscillators drift with temperature and age. The CMT2300H's AFC automatically corrects frequency errors within 8–10 symbols of valid signal reception, compensating for crystal tolerance variations. This enables use of cheaper crystals (lower cost, still reliable) without sacrificing link robustness.

Phase Jump Detector (PJD) Rather than requiring MCU intervention for every received signal, the CMT2300H's PJD observes received signal characteristics: phase transitions, FSK deviation, signal-to-noise ratio to distinguish wanted signals from noise. Invalid signals don't wake the MCU. This reduces unnecessary wake cycles, directly extending battery life in noise-rich industrial environments.

RSSI and Intelligent Wake-up The received signal strength indicator (RSSI) enables super-low-power Rx mode. Devices wake for brief listening windows. If RSSI exceeds a configured threshold, reception continues; if no signal detected, device returns to sleep. This "listen before sleep" approach maximises battery life by avoiding prolonged reception of background noise when no wanted signal exists.

Transmitter Performance

Transmit specifications demonstrate the power flexibility critical for battery-constrained systems:

Output Power	433 MHz Current	868 MHz Current	915 MHz Current
+20 dBm	72 mA	87 mA	70 mA
+13 dBm	23 mA	27 mA	28 mA
+10 dBm	18 mA	19 mA	19 mA
-10 dBm	8 mA	8 mA	8 mA

These figures underscore a key design principle: use the minimum transmit power necessary for your application. A device operating at -10 dBm consumes 23÷8 = 2.875× less power than the same device at 13 dBm. Over millions of transmissions, this difference determines whether battery life reaches six months or five years.

Power Consumption Analysis: Translating Specifications into Real-World Battery Life

The relationship between transceiver specifications and actual battery life becomes clear when you model a realistic deployment scenario. Consider a typical smart utility meter application using the CMT2300H-TQR-IN.

A standard configuration transmits hourly meter readings using two AA batteries with a 2.1 Ah nominal capacity. At 10 kbps data rate and 10 dBm transmit power (adequate for 500 metre urban coverage), the power consumption profile reveals where battery life is actually spent.

Most operational time is sleep mode. Across each hour, the transceiver sleeps for 59 minutes and 50 seconds with the sleep timer active, consuming 800 nanoamps. That translates to just 0.003 milliamp-hours per hour. Transmission consumes more energy per minute of actual operation, but happens infrequently. Transmitting a 50-byte reading takes roughly 0.4 seconds of active current at 18 milliamps, using 7.2 milliamp-seconds per transmission. Monthly configuration updates require periodic listening at 7.2 milliamps for brief windows, averaging 4.3 milliamp-seconds per hour.

A basic calculation shows that hourly transmission with frequent listening consumes approximately 11.5 milliamp-hours daily. With 2,100 milliamp-hours available, a two-AA system would theoretically run about 27 days. But this is unrealistic for actual deployments, which assume hourly transmission and frequent receive windows.

In practice, transmission frequency and receive windows are the primary levers for extending battery life. A system transmitting every 4 hours rather than hourly cuts power consumption by 75 per cent. Reducing receive windows to monthly updates further improves the equation. At these realistic duty cycles, total consumption drops to roughly 2 milliamp-hours per hour.

With this profile, a two-AA battery system achieves approximately 5 months of autonomous operation. Adding a third or fourth AA cell extends this to 10 months or beyond. More aggressive transmission intervals, such as daily or weekly readings, can push battery life into years. The determining factors are not the transceiver specifications in isolation, but rather the system-level choices about transmission frequency and sensing intervals.

The critical insight is that sleep current dominance completely reshapes battery life calculations. The CMT2300H-TQR-IN's 300 nanoamp sleep specification matters because devices spend 99 per cent of their operational life in sleep mode. Traditional transceivers consuming 10 or 20 microamps in the same state would exhaust the same battery in weeks rather than months. It is not any single specification driving extended battery life, but rather the entire system architecture working coherently across the full operational cycle.

Comparing Sub-1GHz to Alternatives: Why the CMT2300H Stands Out

2.4 GHz ISM Band (Bluetooth, Zigbee, Wi-Fi)

• Pros: Abundant development tools, standardised protocols, high data rates

• Cons: Higher path loss requires higher transmit power; more interference; higher receiver current

• Power comparison: 2.4 GHz Bluetooth device typically consumes 30–40 mA receive current; CMT2300H achieves 7.2 mA - 5–6× more efficient

• Best for: Short-range applications (< 50m) where protocol ecosystem is critical

LTE-M and NB-IoT Cellular

• Pros: Wide coverage, standardised, global deployment

• Cons: Cellular overhead, modem power consumption, subscription costs

• Power comparison: Cellular modems consume 100+ mA per transmission; CMT2300H uses 18–23 mA for equivalent power output

• Best for: Applications requiring wide coverage or seamless roaming across service territories

LoRaWAN (868 MHz, 915 MHz)

• Pros: Long range, low power, global standards

• Cons: Limited network availability outside major cities; higher latency; license/subscription for private networks

• Power comparison: LoRa transceivers similar power profile to CMT2300H but it offers more flexible modulation (FSK, OOK, MSK) for custom protocols

• Best for: Wide-area networks where standardised LoRa infrastructure exists

Licensed ISM Bands (900 MHz in USA, 434 MHz in Europe)

• Pros: Lower path loss than 2.4 GHz; less interference; proven industrial reliability

• Cons: Limited regulatory flexibility; region-specific frequency allocations

• Power comparison: Sub-1GHz licensed transceivers match CMT2300H power profiles; CMT2300H offers unlicensed operation

• Best for: Utilities and industrial applications where frequency stability and regulatory simplicity matter

The CMT2300H excels for applications requiring flexible, custom protocols with minimal power consumption and multi-year battery life. Its support for 127–1020 MHz enables global deployment with region-specific frequency selection (433 MHz Europe, 915 MHz North America, etc.), whilst maintaining consistent ultra-low power characteristics.

Enabling Years of Autonomous Operation

Battery life is the binding constraint for industrial IoT devices. Traditional wireless solutions force engineers to choose between frequent maintenance, oversized batteries, or short deployment windows. This equation has frustrated IoT system designers for over a decade.

Sub-1GHz RF transceivers like the HopeRF CMT2300H fundamentally reframe the problem. Through ultra-low sleep current (300 nanoamps), intelligent packet handling that eliminates unnecessary MCU wake cycles, superior sensitivity enabling lower transmit power, and frequency flexibility supporting global ISM bands, these transceivers enable years of continuous operation from standard batteries.

The CMT2300H doesn't achieve this through a single innovation but through coherent system design optimising across the entire operational lifecycle. Sleep current matters because devices sleep. Sensitivity matters because weak-signal reception enables lower transmit power. Integrated packet handling matters because industrial environments contain continuous RF noise. Frequency agility matters because channel diversity improves reliability without proportional energy cost.

For smart utility metering, industrial equipment monitoring, environmental sensing, and distributed IoT networks where device access is costly and battery replacement disruptive, the CMT2300H represents a genuinely transformative capability: autonomous operation measured in years rather than months, without sacrificing range, data rate, or reliability.

If your industrial IoT application requires extended battery life, multi-region deployment capability, and flexible custom protocols, the CMT2300H deserves serious consideration. The technical specifications translate into tangible deployment benefits: reduced maintenance burden, lower total cost of ownership, and systems that genuinely become autonomous after installation.

FAQs - design-in the CMT2300H

What is the CMT2300H?

A: The CMT2300H is an ultra-low power sub-1GHz RF transceiver manufactured by HopeRF. It operates across 127–1020 MHz frequency range supporting OOK, FSK, and MSK modulation. Specifically engineered for battery-powered IoT applications, the transceiver achieves 300 nanoamp sleep current, -121 dBm sensitivity, and integrated packet handling to minimise MCU wake cycles. The QFN16 package and 1.8–3.6V operation make it suitable for compact designs and full battery discharge utilisation

How does the CMT2300H extend battery life compared to 2.4 GHz wireless solutions?

A: Sub-1GHz operation propagates further with lower transmit power due to superior propagation characteristics at lower frequencies. The CMT2300H achieves -121 dBm sensitivity (better than most 2.4 GHz alternatives), enabling reliable communication at lower transmit power levels. Combined with 300 nA sleep current versus typical 10+ µA for 2.4 GHz transceivers, the CMT2300H consumes 30–50× less power during sleep, the dominant state for most IoT applications.

Can the CMT2300H operate in my geographic region?

A: The CMT2300H supports 127–1020 MHz operation, covering ISM bands globally: 433 MHz (Europe/Asia), 868 MHz (Europe), 915 MHz (North America), and others. Regulatory compliance (CE, FCC) depends on specific frequency selection and antenna design - consult local regulations. For multi-region deployment, firmware updates can reconfigure frequency without hardware changes, leveraging the transceiver's frequency-hopping capability.

What modulation schemes does the CMT2300H support?

A: The transceiver supports OOK (On-Off Keying), FSK (Frequency Shift Keying), GFSK (Gaussian FSK), and MSK (Minimum Shift Keying). This flexibility enables custom protocol design optimised for specific applications. FSK is most common for IoT; GFSK reduces spectral width and adjacent-channel interference; MSK provides constant envelope transmission. Data rates from 0.5 to 300 kbps accommodate latency-flexible and real-time applications.

How does the integrated packet handler reduce power consumption?

A: Traditional transceivers forward every received signal to the host MCU for assessment, forcing the MCU to wake repeatedly even for noise or invalid packets. The CMT2300H's integrated packet handler performs preamble detection, sync word recognition, and CRC validation in hardware. Only valid packets trigger MCU interrupts. In noisy industrial environments, this hardware filtering eliminates thousands of unnecessary wake cycles per day, extending battery life by 30–50 per cent compared to simpler transceivers.

What is the maximum transmission range of the CMT2300H?

A: Range depends on transmit power, antenna design, environmental path loss, and acceptable data rate. At 20 dBm with proper antenna impedance matching, expect 3–5 km in open space, 500–1000 metres in typical urban/industrial environments. At reduced power (10 dBm), range decreases to 1–2 km open space, 200–400 metres urban. Lower data rates (2 kbps) achieve longer range at -121 dBm sensitivity than higher rates (300 kbps, -103 dBm sensitivity). Application note AN141 provides detailed range calculations for specific scenarios.

How do I select transmit power to optimise battery life?

A: Calculate actual path loss for your deployment using standard propagation models (Friis equation for free space, ITU models for built environments). Select the minimum transmit power yielding target link margin (10–20 dB is typical). For a 500m urban link, 10 dBm often suffices; 13 dBm provides margin for interference. Maximum power (20 dBm) is rarely necessary outside specialised applications. Transmit current scales linearly: 10 dBm consumes 18 mA, 13 dBm 23 mA, 20 dBm 72 mA. Reducing power by 3 dBm saves 5 mA per transmission - the compound effect over millions of transmissions.

Q: What are the typical application timeframes before battery replacement is needed?

A: Battery life depends entirely on duty cycle. A device transmitting 50-byte packets every 4 hours using optimised sub-1GHz protocol typically achieves 1–3 years from two AA batteries. Devices transmitting hourly may need battery replacement every 3–6 months. Devices transmitting only on alarm (triggered events) can operate 5+ years. The CMT2300H's 300 nA sleep current ensures that standby doesn't limit life; transmit frequency and power determine practical battery duration. System-level design (optimal packet structure, transmission intervals, transmit power) matters more than any single IC specification.

How does the CMT2300H compare to LoRaWAN transceivers?

A: Both operate sub-1GHz with similar power profiles. Key differences: LoRaWAN is a standardised protocol with public networks (coverage varies geographically); CMT2300H is a flexible transceiver enabling custom protocols. LoRaWAN offers longer range (10+ km rural) through spreading factors; CMT2300H achieves comparable range at lower latency. LoRaWAN networks require subscription and centralised architecture; CMT2300H enables peer-to-peer or custom mesh networks. Choose LoRaWAN for geographic coverage reliance; CMT2300H for protocol flexibility and cost control.

What development tools and reference designs exist?

A: HopeRF provides RFPDK (RF Parameter Design Kit) for configuration, register generation, and frequency calculation. Multiple reference schematics exist for 13 dBm and 20 dBm direct-tie and RF-switch configurations. Application notes (AN141–AN197) cover schematic design, PCB layout, FIFO operation, frequency hopping, and low-power modes. Third-party development boards and code libraries are available via distributors like Ineltek, including example projects for common applications (meter reading, sensor networks).

Is the CMT2300H suitable for harsh industrial environments?

A: The CMT2300H operates from -40 to +105°C junction temperature, covering extreme industrial conditions. ESD rating (±2 kV human body model) and latch-up tolerance (±100 mA @ 105°C) meet industrial robustness requirements. Integrated power-on reset, low-voltage detection, and comprehensive protection circuits ensure reliable operation in power-constrained, electromagnetically noisy environments. Proper PCB layout (ground planes, supply filtering) and component selection ensure industrial-grade reliability. The -T designator indicates extended industrial temperature rating.
