Powering IoT Connectivity Worldwide

In today’s IoT landscape, reliable long-range, low-power connectivity is make-or-break for real-world applications—from smart farms to urban automation. That’s where Bivocom LoRa IoT Solutions come in, accordingly. The Bivocom lineup—including the TW820 LoRa Modem, TG501 Outdoor LoRa RTU, and TG452 LoRa Gateway—solves key challenges of traditional wired or 4G communication. Accordingly, it delivers the range and efficiency required for successful IoT deployments. Whether monitoring soil moisture or controlling HVAC systems, Bivocom turns complex connectivity into a plug-and-play process.

Bivocom leads industrial IoT connectivity with its “LoRa+” philosophy. This approach enhances LoRa’s native strengths—long range, low power, and anti-interference—with industrial-grade durability, security, and flexibility. The product lineup targets all layers of the IoT stack, from edge connectivity to network aggregation. Consequently, it is ideal for demanding applications across global markets. Common LoRa capabilities are consistently integrated across devices. These capabilities include 10km open-air range, AES over-the-air encryption, and global 850~931MHz band support. This integration ensures robust and standardized connectivity, undoubtedly.

TW820 LoRa Modem: Simple Connectivity Bridge

The TW820 is Bivocom’s entry-level LoRa modem. It acts as a plug-and-play bridge between low-power devices (e.g., smart meters, basic sensors) and upper IoT systems. It distills LoRa’s efficiency into a compact form, designed for ease of use, and supports small-scale data transmission without complex programming. Its core value lies in two critical strengths:

• Seamless legacy system integration: Equipped with 1 RS232 (debugging) and 1 half-duplex RS485 port, it connects directly to most existing sensors and meters. Therefore, it eliminates adapters, reduces setup time, and lowers technical overhead—even for non-expert teams.

• Rugged design: It operates from -35°C to +75°C and accepts 5–35VDC input. Thus, it performs reliably in factories, remote sites, or utility cabinets where temperature and power stability are issues.

This “no-fuss” design makes the TW820 ideal for smart metering (electricity, water), basic environmental monitoring (soil moisture), and low-movement asset tracking—use cases where consistent LoRa connectivity matters more than on-site control.

TG501 Outdoor LoRa RTU: All-in-One Controller

Unlike the TW820 (a pure connectivity device), the TG501 is a Remote Terminal Unit (RTU)—a hybrid solution that combines LoRa’s long-range communication with on-site data collection and actuation. It is built for outdoor use cases such as triggering irrigation or alarms, while retaining the lineup’s core LoRa performance. Its standout value comes from solving two key outdoor IoT pain points:

• Integrated field operations: It includes 4 digital inputs (DI) for basic sensor data, plus optional add-ons like 2 relays (for actuating devices), 3 analog inputs, and 1 12V/1A power output to power external devices. Thereby, it replaces separate devices, simplifies wiring, and reduces failure points.
• Hardened design: With an IP67 rating, die-cast aluminum housing, and extended temperature tolerance, it withstands harsh weather. Additionally, it includes a 32-bit MCU and 16MB storage for local data logging—crucial for offline operation in remote areas.

TG452 Programmable LoRa Gateway: Scalable Network Hub

The TG452 serves as the central hub of Bivocom’s LoRa ecosystem. It aggregates data from hundreds of nodes and routes it to cloud or on-prem systems. Three core strengths define its value for enterprise users：

• Dual-modem redundancy: It pairs LoRa with 4G LTE (and optional Wi-Fi/GPS), featuring dual SIM/module support for failover and load balancing. Hence, it ensures zero downtime in applications like healthcare or industrial monitoring.

• High programmability: Running on an OpenWRT-based Linux OS, it supports development in Node-RED, Python, and C/C++. This lets users build custom logic (e.g., real-time data filtering, local analytics) without relying on cloud platforms—ideal for industries with strict data privacy or low-latency requirements (e.g., manufacturing).
• Full-spectrum compatibility: It includes 4 RJ45 Ethernet ports (for wired PLCs), 2 RS232, and 3 RS485 (for legacy sensors). It also has a 32GB Micro SD slot for local backup. This flexibility integrates both LoRa and non-LoRa devices. Consequently, it unifies fragmented IoT systems and reduces the need for multiple gateways.

BMS & HVAC: Smarter Control, Lower Costs

Building automation struggles with decentralized HVAC systems, costly wiring, and disjointed data. Bivocom’s LoRa transforms this with wireless, low-power networks that unify HVAC data and sync with BMS. Consequently, building managers achieve energy savings and steady indoor environments—without manual intervention.

• Do Bivocom LoRa devices work with LoRaWAN sensors?
  No. Currently, they only communicate with other Bivocom LoRa devices (no LoRaWAN support). LoRaWAN/MESH compatibility is planned for future development.
• What frequencies do Bivocom LoRa devices use?
  They operate on a fixed 850–931MHz range.
• What transmission specs do they offer?
  1. Power levels: 21dBm, 24dBm, 27dBm, 30dBm.
  2. Data rates: 1.2–62.5kbps (8 levels; 4.8kbps default). Higher speeds reduce range, while lower speeds extend it.
  3. Max range: Up to 10km in open air, though obstacles or interference will shorten this.
• How many nodes can one gateway support?
  Theoretically, 255 nodes per group—limited by the LoRa module’s capacity.
• What antenna should I use?
  A LoRa-specific antenna. The standard included model works for 868–915MHz. For frequencies outside this range, contact Bivocom’s tech team for recommendations.
• What frame interval is best?
  Set it to at least 200ms (for both frames and commands). Shorter intervals can cause delays or data loss due to congestion.

Looking ahead, Bivocom continues to innovate within the LoRa ecosystem. It is expanding compatibility, enhancing protocol flexibility, and integrating smarter edge capabilities. These steps support next-generation IoT applications, furthermore.
