How Sera4 Access Points Enable IoT Networks Where There Is No Network

Learn how Sera4's patented distributed data architecture ensures secure and reliable access control for remote sites, even when power and data service are down.

Introduction

Internet of Things (IoT) networks are transforming the way we manage and monitor physical assets, from telecom towers to water wells. IoT devices, such as sensors, cameras, and locks, can collect and transmit data to a central server or cloud platform, enabling real-time visibility and control over remote sites. However, what happens when there is no network? How can IoT networks provide value when power and data service are disrupted or unavailable?

Let’s review how Sera4 access points, originally designed to secure telecom towers, work flawlessly when a cell site is down, allowing workers in to fix the situation. We will also compare Sera4 access points with other access control solutions that are designed for always-on, always-connected situations, and show why Sera4 access points are the best choice for remote sites. Finally, we will demonstrate how Sera4 access points use a patented distributed data architecture to maintain control of who should get in and accurate access logs of who did get in, and how they securely and reliably deliver that information back to our customers.

How Sera4 Access Points Work When There Is No Network

Sera4 access points are smart locks that can be installed on any door, gate, or cabinet. They use wireless technology that’s built into every mobile phone to communicate with authorized users’ smartphones, allowing them to unlock the access points with a digital key. Sera4 access points also have a built-in backup battery that can power them independently in case of a power outage.

When a cell site is down, Sera4 access points can still operate without any data service. They can authenticate users’ digital keys offline, using a cryptographic algorithm that verifies the key’s validity and expiration date. They can also store access logs locally, recording who accessed the site, when, and for how long. Sera4 access points can also detect tampering attempts and trigger alarms if someone tries to force or cut the lock.

By contrast, other access control solutions that rely on Wi-Fi, cellular, or cloud connectivity may not work when there is no network. They may require constant communication with a server or platform to validate users’ credentials and grant access. They may also lose access logs or security alerts if they cannot transmit them to the cloud. These solutions may be suitable for offices, hotels, and residences, where power and data service are usually stable and available, but they are not ideal for remote sites, where network disruptions are more common and critical.

How Sera4 Access Points Use a Patented Distributed Data Architecture

One of the most innovative features of Sera4 access points is their patented distributed data architecture, which ensures secure and reliable data transmission between the access points and the cloud platform.  

When there is no network, Sera4 access points can still exchange data with the user’s mobile phone whenever they are around. They synchronize digital keys, access logs, and security alerts, creating a consistent and updated view of the site. Even when offline, The mobile phone acts as a gateway to upload the data to the cloud, where our customers can access it through a web portal or an API. Sera4 access points can also download data from the mobile phone, such as new access policies or firmware updates. 

This distributed data architecture allows Sera4 access points to overcome the challenges of network availability and latency that affect remote sites. It also provides a high level of data security and integrity, as the data is encrypted and signed at each step of the transmission. Sera4 access points can also detect and reject any corrupted or tampered data, ensuring that only valid and authorized data is accepted and processed. 

Conclusion

Sera4 access points are the best solution for IoT networks where there is no network. They can work flawlessly when a cell site is down, allowing workers to access the site and fix the situation. They can also maintain control of who should get in and accurate access logs of who did get in, and securely and reliably deliver that information back to our customers, using a patented distributed data architecture. Sera4 access points are designed for remote sites, where network disruptions are more common and critical, unlike other access control solutions that are designed for always-on, always-connected situations.
