Why connected diagnostics fail in remote clinics, and how to fix it

A rapid diagnostic test can deliver a result in minutes. But if that result never leaves the device, it doesn't help the patient, the clinic or the health programme behind it.

That's the hidden problem in many digital health deployments. They struggle not because the software falls short, but because the connection does.

The problem: the connection, not the device

Field teams often work in places where cellular coverage is unreliable, internet infrastructure is unstable and there's little or no network redundancy. Many programmes also run across borders, so devices move between roaming environments and countries.

For the teams running these programmes, that creates a familiar list of headaches:

•       Managing contracts with several local mobile providers

•       Roaming performance that changes from one country to the next

•       Keeping health data systems reachable at all times

•       Sending sensitive medical data securely

•       Scaling a deployment from a pilot to many countries

When a device goes offline, results wait. And in diagnostics, waiting has a real cost.

If a patient has to wait days for a result, many simply don’t come back. They leave the clinic without a diagnosis and go untreated, and with an infectious disease, they can pass it on to others.

Faster results save lives. They let clinics act while the patient is still within reach.

The fix: connectivity first, then data

Telecom26 and BAO Systems built their partnership around a simple idea: get the connectivity right first, and the data will follow.

Telecom26 keeps devices online. Its multi-IMSI SIM and eSIM connectivity gives each device access to more than 1,100 mobile networks in over 200 countries and territories. If one network drops, the SIM switches automatically to another. Data travels over secure routing, with direct-to-cloud links that keep it off the public internet. Everything is managed centrally, under one provider.

BAO Systems gets the data where it's needed. BAO ConneX securely collects results from point-of-care devices and delivers them to central health information systems. It integrates with lab systems, EMRs and national health systems such as DHIS2, and runs cloud-hosted or on-premise in-country.

In practice: rapid testing across remote Africa

A major global healthcare company uses this setup for its rapid diagnostic platform. The devices test for infectious diseases and other conditions in pharmacies, laboratories and remote clinics, across thousands of locations. Many of those sites are in decentralised parts of Africa where connectivity is unreliable.

Here's how a result travels:

1.     The diagnostic device completes a test.

2.     Telecom26's multi-network IoT SIM keeps the device connected, switching networks when needed.

3.     BAO ConneX Link sends the result over cellular data into DHIS2.

4.     DHIS2 automatically sends the result by SMS to lower-level clinics.

The result reaches the people who need it in near real time, even from places where traditional communications infrastructure is limited. That means clinics can act on a result quickly, instead of waiting for a patient who may never come back.

What changes for health programmes

•       Reliable connectivity across countries and roaming environments, with less disruption

•       Faster data, with real-time or near-real-time transmission and better programme visibility

•       Simpler operations, with one global framework instead of many local carriers and roaming agreements

•       Room to scale across pharmacies, clinics, laboratories and field operations

As Nicola Berardocco, CEO of Telecom26, puts it: “Reliable connectivity is an essential component of digital public infrastructure.”

Meet us at MEDICA 2026

Telecom26 and BAO Systems will be at MEDICA 2026 in Düsseldorf. If you build or deploy connected medical devices, from point-of-care analysers and lab equipment to remote monitoring, cold chain and telehealth, let's talk.

Book a meeting with David McCanny, or reach us through MEDICA Fair Match.
