What is LTE Cat-1 BIS?

LTE Cat-1 BIS is a streamlined 4G communication standard for IoT, introduced in 2016 as part of 3GPP Release 13. Unlike LTE Cat-1, it operates with a single antenna, making it a more cost-efficient and compact solution while utilizing existing LTE networks.

When connecting IoT devices, Cat-1 BIS is often evaluated alongside LTE-M and NB-IoT, two low-power wide-area network (LPWAN) technologies. These three options are popular for transitioning from 2G and 3G networks, which are being gradually phased out.

While LTE-M and NB-IoT are frequently preferred due to their extended battery life, Cat-1 BIS holds distinct advantages despite its slightly higher power consumption.

It provides more consistent and flexible coverage compared to LPWAN technologies, as it is  globally available on standard 4G deployments. This broad acceptance ensures widespread network availability and critical roaming agreements, which are essential for international IoT deployments.

Why LTE Cat-1 BIS Stands Out

LTE Cat-1 BIS leverages existing 4G infrastructure to deliver a scalable, reliable solution for a variety of IoT applications. Its key features make it particularly well-suited to meet diverse needs:

Single-Antenna Advantage

• Reduces device complexity and cost.
• Operates seamlessly on 4G LTE networks with widespread coverage and roaming capabilities, making it an excellent option for devices that move across national boundaries, such as asset trackers.

Cost Efficiency

• Simplified architecture minimizes production costs, often aligning with the price points of LTE-M and NB-IoT solutions.

Use Cases for LTE Cat-1 BIS

LTE Cat-1 BIS caters to a range of IoT applications that demand dependable connectivity and practical functionality:

• Asset Tracking: Real-time monitoring of vehicles and equipment, especially when crossing borders.
• Smart Metering: Efficient utility management through remote monitoring.
• Retail & Payments: Reliable connectivity for POS systems and vending machines.
• Telematics: Vehicle diagnostics and usage-based insurance applications.
• Smart Cities: Monitoring traffic flow and environmental conditions.

Why Consider LTE Cat-1 BIS?

In addition to its compatibility with 4G networks and global roaming agreements, Cat-1 BIS is suitable for devices that use SMS, voice, or data services, such as wearables, healthcare monitors, and lone worker devices. These features make it a strong contender for IoT deployments replacing 2G and 3G, especially in scenarios where safety and mobility are key.

Navigating IoT migrations, first-time deployments, or scaling requires careful planning. Cat-1 BIS stands out for its flexibility, cost-effectiveness, and technical capabilities. Partnering with a connectivity provider can help enterprises evaluate options and implement solutions tailored to their unique requirements.

Future-Proofing with LTE Cat-1 BIS

With 2G and 3G sunsets accelerating, LTE Cat-1 BIS is a natural migration path. Its reliance on existing 4G infrastructure ensures ubiquitous connectivity even in 2G/3G sunset regions.

Key Considerations for IoT Developers

When selecting a connectivity standard, developers must assess factors such as:

• Data Requirements: LTE Cat-1 BIS handles larger data volumes more efficiently than LTE-M or NB-IoT.
• Coverage and Roaming: Offers seamless global connectivity, unlike NB-IoT.
• Device Size and Cost: The single-antenna design minimizes size and expense.
• Power Consumption: Features like PSM and eDRX ensure prolonged battery life. For battery powered devices, the power consumption should be evaluated towards the more power efficient LTE-M and NB-IoT that also have features like PSM and eDRX available.
