The New Era of Fixed Wireless Broadband: Exploring Ubiquiti LTU

Hi there! Juan David here, your Tech Lead Support and Ubiquiti certified trainer at Flytec. Today, let’s dive into the revolutionary Ubiquiti LTU platform, a game-changing solution for fixed wireless broadband. Designed for modern wireless ISPs (WISPs) and high-capacity networks, LTU sets a new standard with proprietary technology, unmatched performance, and scalability for the future.

What is Ubiquiti LTU?

LTU, short for Long-Term Ubiquiti, is Ubiquiti’s third-generation wireless technology. Unlike AirMAX or AirFiber products, LTU doesn’t rely on 802.11 protocols. Instead, it uses a proprietary protocol designed to overcome the limitations of traditional Wi-Fi-based solutions. This makes it the ideal choice for:

• WISPs aiming to provide high-speed, reliable broadband.
• Enterprise networks needing long-range connectivity.
• Scenarios where wired infrastructure like fiber isn’t feasible

Why Choose LTU Over Traditional Solutions?

1. Superior Performance

LTU delivers exceptional throughput and low latency, making it perfect for environments where high-speed and reliable internet is a must. For example:

• Throughput: Up to 900 Mbps in Point-to-MultiPoint (PtMP) configurations.
• Packet Processing: Supports 2 million packets per second for seamless data transmission.

2. Scalability

Each LTU-Rocket AP (Access Point) can connect up to 100+ client devices, ensuring you can scale your network as your user base grows.

3. Flexible Bandwidth

With channel width options ranging from 10 MHz to 100 MHz, LTU allows for:

• Efficient frequency usage.
• Support for long-distance links, reaching up to 100 kilometers (with ideal environmental conditions).

4. Advanced Noise Mitigation

Noise is the enemy of wireless networks, especially in high-density areas. LTU products feature advanced RF filtering and support for horn antennas to reject interference and maintain stable connections.

5. GPS Synchronization

Built-in GPS sync enables precise timing between APs, reducing co-channel interference and enhancing overall network performance.

The LTU Product Family

The LTU lineup offers a range of products tailored to different deployment scenarios. Let’s take a closer look:

1. LTU-Rocket

• Role: Base station for PtMP networks.
• Key Features: Operates in the 5 GHz band, supports over 100 clients per AP, and includes proprietary RF filtering for enhanced noise rejection.
• Compatible Antennas: Works seamlessly with Ubiquiti sector antennas (e.g., AM-5G19-120, AM-5G16-120) and third-party horns like RF Elements.

2. LTU CPEs (Customer Premises Equipment)

Designed for client-side connectivity, these devices include:

• LTU-Lite: Ideal for short-distance deployments (up to 10 km).
• LTU-LR: Long-range option for distances up to 30 km.
• LTU-Pro: Offers the highest performance for premium client setups.
• LTU-XR: Extreme range capabilities for distances over 30 km.

Applications of LTU Technology

LTU’s versatility makes it suitable for a wide range of use cases, including:

1. WISPs

Provide reliable internet access to rural or underserved areas where fiber installation isn’t practical. LTU ensures high bandwidth and stable connectivity over long distances.

2. Campus Networks

Deploy PtMP networks to connect multiple buildings in universities, business parks, or large campuses.

3. Public Sector

Support applications like IP-based video surveillance or emergency communication systems.

Centralized Management with UISP

Managing an LTU network is effortless with UISP (Ubiquiti Internet Service Provider), a free centralized platform for configuration, monitoring, and updates. Key features include:

• AirLink Tool: Simulate link performance and coverage before deployment.
• Firmware Management: Schedule and roll out updates across the network.
• Analytics: Monitor device health, throughput, and latency for proactive maintenance.

What Makes LTU Stand Out?

Proprietary Technology

Unlike other platforms, LTU operates on custom-designed silicon, delivering performance that surpasses 802.11-based solutions.

Backward Compatibility

While LTU is not compatible with AirMAX or AirFiber products, this ensures an optimized ecosystem designed for the best performance.

Unmatched Range

Achieve reliable connectivity for distances up to 100 kilometers or more, depending on device, antenna gain, and line-of-sight conditions.

Low Latency

With latency as low as 2-3 ms when using the shortest frame length.

Final Thoughts: The Future of Fixed Wireless

The Ubiquiti LTU platform represents the cutting edge of fixed wireless broadband technology. With its unmatched performance, scalability, and ease of deployment, LTU is the ideal choice for WISPs and businesses looking to deliver reliable, high-speed internet.
