Private LTE (CBRS) Network Solutions
Private LTE: A Secure, High-Speed Network for Enterprise and Industrial Applications
The growing number of connected devices is driving new requirements for a variety of industries that traditional public networks cannot address. For example, utilities and other verticals are exploring private network solutions so that they can deploy devices in secure and on-premises environments that may not offer public network access. When it comes to wireless networking, enterprises are always looking for ways to provide better coverage with seamless roaming and the ability to switch from public to private networks on campuses, in warehouses and other corporate environments both indoors and out.
Many organizations are addressing these escalating requirements by turning to private LTE, a dedicated wireless network separate from the wide-area macro network. It is used for specific Internet of Things (IoT) applications and services and targets verticals, such as mining, industrial and automotive manufacturing, utility metering, logistics, smart cities, drones, transportation hubs, hospitals, enterprises, campuses, stadiums and other environments.
Telit is at the forefront of this new technology, bringing decades of cellular leadership to offer you an end-to-end private LTE solution that extends from the modules themselves to connectivity, platforms and solution expertise. With Telit’s private LTE module, you will find the right features at the right price with solutions that support the next wave of IoT innovation.

Benefits of Private LTE
A private LTE network gives you a variety of advantages over other options like Wi-Fi, such as:
- Cybersecurity: A private LTE network can be a “best of both worlds” solution, providing all the benefits of cellular while enabling you to keep all your corporate data behind your firewall. Wi-Fi is more susceptible to security breaches and hacking attacks, whereas LTE is generally considered more secure at the enterprise level than Wi-Fi.
- Latency management: For industrial processes in which automation network latency times are critical, private LTE allows your IT team to specify latencies to infrastructure providers.
- Legacy connectivity replacement: Cellular technology is considered more robust and scalable than Wi-Fi. This scalability makes it a superior wireless solution for mission-critical use cases, like land mobile radio systems (LMRS) and public safety applications. Cellular networks are also ideal for fault-tolerant operations, such as mining, rail and energy distribution.
- Expanded bandwidth: Most of the private LTE spectrum is broader than many current wireless technologies. For example, in the United States, the Citizens Broadband Radio Service (CBRS) is a 150 MHz of bandwidth in the 3.5 GHz band.
- Future-proofed for 5G: 3GPP has approved 5G NR operation in the 3.5 GHz CBRS spectrum band. Private 5G builds on private LTE to bring the enhanced features of 5G NR to the private network space like higher speeds (especially in the uplink) and ultra-low latency which play an important role in industrial manufacturing and mission-critical use cases.
These advantages and more make private LTE a fast, secure, cost-effective choice for many use cases across industries, utilities and government.
CBRS and Private LTE
Mobile operators or private companies can run private LTE and use a licensed, unlicensed or shared spectrum. In the United States, the most mature shared spectrum is Citizens Broadband Radio Service (CBRS). CBRS was created to open the 3.5 GHz band to a wide range of users, including incumbent users, mobile and cable operators, other service providers, public entities and enterprises.
Telit was the first top-tier IoT and mobile broadband module vendor to join the CBRS Alliance, an organization focused on supporting the development, commercialization and adoption of LTE and 5G solutions for the CBRS band in the 3.5 GHz spectrum band, also known as Band 48 (B48). Our active participation in the alliance will help drive innovation and adoption of private LTE and private 5G, giving enterprises new options for site, campus and office wireless networking.
CBRS private LTE offers a variety of benefits, such as:
- LTE performance with Wi-Fi simplicity: For enterprise organizations, CBRS delivers the capacity, traffic management capabilities, latency, reliability and security of LTE required for industrial IoT and other critical applications. CBRS can offer ease of deployment and operations compared to those of Wi-Fi, enabling you to deploy standalone networks that you can — but do not have to — connect to a mobile network operator (MNO).
- Out-of-the-box solutions: CBRS vendors offer to reduce LTE complexity with small cell solutions that work out of the box and do not need a carrier-scale, macro-core network.
- Wireless networks customized to your needs: Building and operating any wireless network is expensive, yet it is essential for today’s increasingly connected enterprises. CBRS provides a cost-effective way to deploy and manage standalone cellular networks on the premises in a spectrum band that does not require an expensive license.
- On-premises networks: On-premises networks deliver more power and flexibility for managing security. Sensitive data stays on the premises instead of going back to the core network of an operator. They are also ideal for edge computing and network slicing, enabling your enterprise to run and manage applications locally for optimized performance and minimal latency.
CBRS, which is backed by U.S. regulators and government agencies, can support the expansion of 4G and 5G into new consumer and industrial applications. Telit’s expertise in enterprise-grade mobile broadband and IoT solutions, together with our experience supporting customers in go-to-market strategies for products and solutions involving heavily regulated wireless standards (e.g., cellular) make us a natural fit for the alliance.
Use Cases for Private LTE
- Locations not covered by public wireless infrastructure
- Industries requiring automated machinery, such as mining and agriculture
- Sectors requiring hardened equipment and low-density, long-range coverage
Automation and Industry 4.0
- Factory-floor robotics such as wireless robots for greater flexibility in production line reconfiguration
- Logistics and warehousing machinery such as pick-and-pack machines
- Environments with devices in dense deployments and with low latency requirements
- Monitoring and control of utilities and other critical infrastructures, such as electricity distribution grids and power plants
- Enabling public safety agencies to create closed user-group, ad hoc networks at emergency scenes
- Developing dedicated, highly available networks for government and military agencies
- Public venues such as airports, stadiums, hospitals and ports
- Sites with many users, including employees, contractors and visitors who require fast, highly secure access
- Sites that require a private network that is configurable for different user groups
Case Study: Rio Tinto Improves Mining Safety and Reliability
Australian mining conglomerate Rio Tinto is one of the first large enterprises to use a private LTE network to support commercial operations at scale. The company developed a solution to cover 15 mines and related facilities, including transport hubs, railways, ports, offices and other sites. The solution delivers:
- Improved reliability and resiliency for production and safety-critical services with full wireless coverage of all operational areas
- Ability to utilize QoS and prioritize traffic safety and production-critical traffic
- A consolidated network platform to support multiple in-pit systems concurrently
- Reduced infrastructure requirements with four LTE communications trailers instead of 30 Wi-Fi communications trailers
