As the demand for reliable, high-speed wireless communication continues to surge, especially in rural and suburban deployments, Sub-6GHz PTP (Point-to-Point) and PTMP (Point-to-Multipoint) proprietary solutions have emerged as essential tools for last-mile broadband, backhaul, surveillance, and industrial connectivity. Operating below the 6GHz spectrum, these systems deliver robust non-line-of-sight (NLoS) and long-range capabilities that make them ideal for a wide array of real-world challenges where fiber or millimeter-wave solutions fall short.

🌐 What are PTP and PTMP Solutions?

• PTP (Point-to-Point): Involves a direct wireless link between two nodes—typically used for backhauling data from one network point to another, such as between two buildings or a tower and a central office.

• PTMP (Point-to-Multipoint): A central hub or base station communicates wirelessly with multiple end-points or subscriber units. Commonly used in wireless ISPs (WISPs), video surveillance, and industrial monitoring.

Both topologies benefit greatly from Sub-6GHz spectrum, especially when designed with proprietary enhancements to increase throughput, reliability, and interference resistance.

📡 What is Sub-6GHz?

Sub-6GHz refers to frequencies below 6 gigahertz, including key bands like 2.4GHz, 3.5GHz, 4.9GHz, and 5GHz. These frequencies are prized for:

• Longer range and better penetration than higher-band frequencies (e.g., mmWave)

• Cost-effective equipment

• Compatibility with existing infrastructure

• Support for NLoS operation

When paired with proprietary technologies, Sub-6GHz becomes a powerful platform for reliable wireless connectivity.

🔐 Why Proprietary Solutions?

While standards-based systems like Wi-Fi or LTE offer broad compatibility, proprietary Sub-6GHz wireless solutions are tailored for:

• High performance in congested or rural spectrum

• Tighter security controls

• Custom MAC and PHY layer optimizations

• Lower latency and jitter

• Adaptive modulation and interference mitigation

Vendors like Cambium Networks, Ubiquiti, RADWIN, Mimosa, and Tarana Wireless have developed proprietary PTP/PTMP systems that push the limits of what's possible in Sub-6GHz deployments.

🧠 Key Features and Capabilities

1. NLoS and Long-Range Performance

Sub-6GHz signals can traverse obstacles like trees, buildings, and weather conditions more effectively than higher frequencies.

2. High Throughput

Proprietary protocols and channel bonding allow systems to deliver speeds up to 1 Gbps+ over multi-kilometer distances.

3. Advanced QoS

Enable prioritization for voice, video, and critical data to ensure consistent performance.

4. Self-Interference Mitigation

Advanced beamforming and dynamic frequency selection improve spectrum utilization in dense deployments.

5. Flexible Spectrum Usage

Support for licensed, lightly licensed (e.g., CBRS), and unlicensed bands enables flexible, legal deployment globally.

6. Security

Strong encryption (AES-128/256), secure provisioning, and authentication protocols protect against unauthorized access.
