If you’ve ever dealt with connectivity issues on a job site, you know how frustrating it can be to lose valuable data. Competitors’ products often rely on a single communication method, which means a weak signal can leave you with significant data gaps and costly delays.

The Flex Logger was engineered at EXACT to solve this exact problem. It’s built with a sophisticated, three-radio system that creates a redundant connectivity network, ensuring your data is always retrievable – no matter the environment.‍

Connectivity for Every Challenge

The Flex Logger’s redundant system is designed to overcome the most common obstacles to reliable connectivity. We’ve outlined some typical scenarios below and explained how each of the three radios works to get your data out.

1. The Remote Site: No Cellular Signal

Imagine your project is in a remote, rural area where cellular service is weak or nonexistent. A single-LTE device would fail, but the Flex Logger keeps going.
The LoRa® antenna provides a powerful, long-range solution. It works better compared to higher frequency radios in environments where there are a lot of concrete or metal obstacles that can negatively impact the signal. It can transmit data over half a mile (800+ meters) to a nearby gateway, ensuring your data still gets to the cloud, even when your phone can’t get a signal.

2. The Urban Environment: Underground or in Tunnels

Projects in dense urban areas, like underground parking garages, or tunnels, present a unique challenge. Thick concrete and steel can block cellular and other radio signals, making it impossible for a single-LTE device to communicate.
The Bluetooth Low Energy (BLE) antenna is your last line of defense. When other signals fail, you can simply retrieve up to 90 days worth of data from the device using a mobile phone and the companion app. Once your phone regains cloud access, it automatically syncs the data to EXACT Portal, ensuring no information is ever lost.‍

3. Backup Delivery and Memory

Even if your LoRa connection fails, the Flex Logger has a built-in backup delivery system. It will attempt to push all undelivered measurements once daily over LTE if a connection is possible. If radio communication ultimately fails, the device will continue to record data and retain up to 90 days worth of data. This can later be retrieved via the BLE antenna.

Always Connected, Always Delivering

The Flex Logger’s advanced connectivity architecture, driven by its quad-antenna system, marks a new era in remote monitoring.

‍By integrating LTE, LoRa®, BLE and GNSS  technologies, the device provides unprecedented reliability and data accessibility.

‍The meticulous engineering work, including rigorous testing in a 10-meter semi-anechoic chamber, was essential to ensure the seamless operation of all four antennas and adherence to regulatory standards (FCC, IC, CE). This powerful, multi-radio system is not just a technical achievement but a practical solution designed to deliver real-time data on temperature, humidity, and maturity readings. It’s a tool that enables users to make faster, more informed decisions, no matter where their work takes them.

By combining these technologies, the Flex Logger provides a redundant system that addresses common connectivity challenges, from remote sites with no cellular signal to urban environments where thick concrete and steel can block communication. This robust architecture ensures that connectivity failures are mitigated, providing a reliable and resilient tool for modern monitoring needs‍
