Driving High-Performance PTMP Connectivity with the Cambium Force 300-25

Posted: Mon Sep 15 2025

The fixed wireless broadband market is growing rapidly as ISPs extend coverage into suburban, rural, and semi-urban areas. The rising demand for higher bandwidth services, fueled by 4K video streaming, remote work, cloud applications, and the proliferation of IoT devices, is placing significant strain on access networks. In PTMP (Point-to-Multipoint) architectures, the subscriber module plays a pivotal role in delivering performance and reliability while keeping costs under control.

ISPs deploying PTMP solutions face a set of persistent challenges. Spectrum congestion in the 5 GHz band is common, as is interference from competing operators and uncoordinated networks. Expansion efforts must be scalable without requiring costly replacement of core sector equipment. Operational efficiency is essential to control installation and maintenance costs, while customers expect a consistent, high-quality experience regardless of geography or density.

Why the Cambium Force 300-25 is a Game-Changer

The Cambium Force 300-25 is engineered to address these realities directly. It delivers over 500 Mbps UDP throughput in the unlicensed 5 GHz spectrum, enabling ISPs to offer higher service tiers without rebuilding their networks from the ground up. Its integrated 25 dBi dish antenna provides long-range connectivity and exceptional interference rejection, performing reliably in both Line-of-Sight and near-Line-of-Sight conditions. The narrow beamwidth, combined with GPS synchronization support, enables more efficient frequency reuse, critical for high-density ISP environments.

Beyond radio performance, the Cambium Force 300-25 is fully integrated into Cambium’s One Network management approach. Using the cnMaestro platform, ISPs can monitor and control their wireless, switching, and security infrastructure from a single interface, streamlining operations and reducing the need for field interventions. The result is a subscriber module that not only meets technical performance requirements but also aligns with the business goals of reducing OPEX, increasing the average revenue per unit (ARPU), and scaling efficiently to meet growing demand.

Key Features and Benefits of the Cambium Force 300-25

1. Performance and Throughput

High-Speed Throughput: Supports 500+ Mbps UDP throughput in real-world conditions when using an 80 MHz channel width. Optimized for both PMP and PTP modes, allowing reuse in different deployment scenarios.
Channel Bandwidths Supported: 20 MHz, 40 MHz, and 80 MHz, enabling bandwidth optimization based on spectrum availability and interference levels.
Traffic Prioritization (QoS): Implements advanced QoS profiles, allowing ISPs to prioritize latency-sensitive services such as VoIP and IPTV while still delivering high throughput for general data.

2. Antenna and RF Design

Integrated Antenna: 25 dBi dual-polarized dish with narrow beamwidth for high-gain, long-range, and interference rejection in dense PTMP environments.
Beam Characteristics: A narrow beam reduces susceptibility to off-axis interference.
Line-of-Sight and Near-LoS Operation: Designed to operate reliably in both clear LoS and near-LoS conditions, extending service reach even in non-ideal terrain.

3. Network Flexibility

Backward and Forward Compatibility: Works with legacy ePMP 802.11n and 802.11ac subscriber modules, easing network migration and upgrades.
Multiple Deployment Topologies: Functions as a subscriber module (CPE) in PTMP or as a remote endpoint in PTP links for backhaul or specialized customer links.
Flexible Sector Antenna Pairing: Compatible with Cambium sector, horn, and omni AP antennas for customized coverage patterns.

4. Interoperability and Upgrade Path

Backwards and forwards compatibility with other ePMP 802.11n and 802.11ac subscriber modules, allowing seamless upgrades without replacing the entire network.
Proprietary air interface tuned for Cambium’s ePMP architecture ensures predictable performance and better interference mitigation compared to standard 802.11ac gear.

5. Operational Efficiency with One Network
