Network Shutdown: A Temporary Disconnection from Wireless Internet Connectivity

In the rapidly evolving world of technology, airports are making a significant shift towards Private Cellular Networks (PCNs) to meet their growing connectivity needs.

As global air travel is predicted to increase by 40% by 2030 compared to its pre-pandemic high, airports can't afford to let legacy infrastructure slow them down. PCNs, operating over the Citizens Broadband Radio Service (CBRS) spectrum, also known as Band 48, offer a more controlled and secure environment than public networks.

Integrators need to start thinking about PCN competency, as customers may push for a cellular option to save on installation costs. PCNs provide dedicated, high-bandwidth, low-latency secure connectivity across large areas without the need for extensive cabling, making them an attractive choice for airports.

The benefits of PCNs extend beyond infrastructure modernization. They are being used to support drone detection systems, monitor for theft in aircraft luggage holds, and identify perimeter breaches using radar and thermal cameras. Advanced computer vision platforms and innovations like baggage tracking systems and autonomous wheelchairs can thrive on the dedicated bandwidth, low latency, and greater reliability that private cellular networks provide.

AI is another area where PCNs can make a significant impact. AI can be used for improving turnaround efficiencies and reducing delays, but it requires constant video and sensor coverage across all zones, which PCNs excel at providing.

Experts predict up to 80% of airports will ultimately rely on PCNs. Major airports like Minneapolis-St. Paul (MSP), Dallas-Fort Worth (DFW), and Miami International Airport (MIA) are already implementing PCNs. Companies involved in developing private cellular networks for airports include Ericsson, Nokia, Cisco, and Huawei; airports using this technology include Munich Airport, Dallas Fort Worth International Airport, and Hong Kong International Airport.

However, integrators must also consider cybersecurity. Properly authenticating, encrypting, and managing devices on both the PCN and LAN is crucial to ensure the entire system is secure, end-to-end. Customer-facing sales consultants will need to collaborate with network architects who understand how to provision SIMs, get devices on Band 48, and make sure everything is communicating with the core.

Moreover, integrators must ensure the network is set up so traffic can flow between the wired and PCN infrastructures. Many traditional security applications will continue to use the wired network alongside PCNs.

PCNs will revolutionize how connected systems are deployed, accessed, and managed across massive, complex environments. They will become mainstream anywhere that needs real-time visibility, broad-area coverage, and the flexibility to deploy advanced technology quickly and securely. In the era of digital transformation, airports are embracing PCNs as the future of their next-generation connectivity needs.
