Private LTE networks have become a popular option for businesses and industries that require strong security measures, flexible Quality of Service (QoS) protocols, and a greater selection of band frequencies. These networks are designed to meet the needs of businesses when public LTE networks and Wi-Fi Mesh are not satisfactory.

Private LTE Advantages

One of the major advantages of Private LTE networks is the increased security measures. The infrastructure is owned and controlled by the operator, ensuring that sensitive data is transmitted through secure methods and stored locally on-site. In contrast, public networks remove QoS tagging on traffic inflow, making it difficult for businesses to send mission-critical traffic for niche applications.

Another one of the advantages of Private LTE networks is the flexibility in network configuration. Public LTE providers use set band frequencies for their services without providing freedom of choice. Private LTE, on the other hand, allows the choice of band, channel size, and up-link down-link ratio to satisfy specific applications.

Limitations of Legacy Networks

The need for modernization is becoming increasingly evident in industries such as:

1. Oil and Gas
2. Mining
3. Utilities
4. Government
5. Transportation

These businesses and organizations are demanding advanced features such as personal messaging, group chat, file sharing and mission-critical PTT (Push to Talk) but hitting roadblocks on their legacy networks like Land Mobile Radio (LMR) and Wi-Fi networks.

LMR

Modern applications are severely restricted on LMR due to aging infrastructure, proposed spectrum recalls, low network scalability, and restricted data handling capabilities.

Wi-Fi Mesh

Although it is inexpensive for small scale operations, it has numerous limitations that affect its overall performance and functionality in demanding environments.

1. Optimized for localized indoor
2. Maximum range of 90 meters
3. No nomadic mobility support
4. Throughput fluctuations
5. Latency fluctuations
6. Potential dead zones within the area of operation

As technology advances, public safety transport networks are facing the challenge of keeping up with the new requirements for fast and reliable connectivity for emergency responders and everyday operations. In the past, Time-Division Multiplexing (TDM) networks were used for their reliability and low latency, however, as technology surpasses the capabilities of TDM, public safety operators are now migrating to IP/MPLS networks for their scalability, resiliency, and advanced network virtualization schemes.

CTR 8740 and MPLS

One of the key equipment for public safety networks is a high-quality IP/MPLS router, such as Aviat’s CTR 8740, that can quickly migrate to IP/MPLS, build, scale, and manage mission-critical networks under one Network Management System (NMS). The CTR 8740 provides advanced transport router capabilities using MPLS, which is optimized and simplified with Segment Routing, and added resiliency features such as High Availability support and strong security.

To understand the full capabilities of the CTR8740 with MPLS technology and how it can enhance network virtualization, traffic management, and resiliency for mission-critical communications, download our white paper now. It will provide you with an in-depth look at the benefits of MPLS technology and how it can optimize your public transport network for rapid emergency responses and reliable everyday operations.
