As the demand for fast, reliable, and cost-effective broadband access continues to grow across industries and geographies, Sub-6GHz Point-to-Point (PTP) and Point-to-Multipoint (PTMP) proprietary wireless solutions Market size have emerged as a strategic enabler. These technologies provide an efficient alternative to fiber, particularly in suburban, rural, or hard-to-wire locations, enabling broadband, video surveillance, industrial IoT, and enterprise backhaul with low latency and high reliability.
What Are Sub-6GHz PTP and PTMP Solutions?
PTP (Point-to-Point): A dedicated wireless link between two sites—ideal for backhaul, connecting towers, or extending networks.
PTMP (Point-to-Multipoint): A single base station connects to multiple endpoints—efficient for broadband distribution or enterprise networks.
Operating in sub-6GHz unlicensed or lightly licensed spectrum (typically 2.4GHz, 3.5GHz, 4.9GHz, 5GHz bands), these systems use proprietary protocols to enhance range, security, and throughput beyond standard Wi-Fi-based implementations.
Why Sub-6GHz?
Sub-6GHz frequencies offer the ideal balance of:
? Penetration and Range: Better wall and foliage penetration than mmWave
? Lower Latency: Crucial for real-time applications
?️ Cost-Effectiveness: Less expensive than licensed microwave or fiber
? High Availability: Unlicensed bands allow rapid deployment
Proprietary vs. Standards-Based Solutions
| Feature | Proprietary (e.g., Cambium, Ubiquiti) | Standards-Based (e.g., Wi-Fi, LTE) |
|---|---|---|
| Performance Tuning | Optimized for throughput and stability | General-purpose, often shared spectrum |
| Latency | Ultra-low for industrial/backhaul use | Moderate latency |
| Interference Handling | Advanced filtering and channel control | More prone to congestion |
| Flexibility | Tailored to specific use cases | Broad interoperability |
| Cost | Lower TCO due to license-free spectrum | Higher with licensed spectrum |
Key Use Cases
1. Wireless ISP (WISP) Networks
Broadband access in suburban/rural areas
Quick network expansion with minimal civil infrastructure
2. Surveillance and Security
