RF wireless medical / healthcare device design and development

Healthcare Solutions

Most applications for chronic care are largely non-reimbursed and tend to be considered ‘consumer’ Class I FDA devices, though there are exceptions such as consumables for the treatment of Diabetes Mellitus or devices for proof of compliance.

Chronic care devices do need to offer connectivity for provisioning and monitoring of the patient. Solutions for FDA Class I devices, however, tend to be price-sensitive, compared to Class II/III. The requirements for the latter in Acute and RUO (Research Use Only) products are radically different.

As an example, where BER/FER rates for consumer devices of 3-5% might be acceptable for a consumer Class I device, that would be intolerable for a Class II/III device intended for in-hospital deployment. Product specifications, documentation, process management, engineering, manufacturing, and deployment are all set to a much higher standard with devices that are deployed in life/death situations. Latency is a much more important parameter for acute care applications than for example throughput or range. While all these factors set essential design constraints, trade-offs in total system implementation is what sets RTX apart.

RTX has built years of expertise in the design and manufacturing of devices that are intended for these more specialized and challenging markets.

From wireless systems that monitor critically ill patients to hearing aid accessories, we have the experience, technology, and industry understanding to help you conceive, design and manufacture unique wireless devices.

Available technologies

Proprietary radio in licensed and ISM bands

We have a long track record designing systems for license-free bands, but using a dedicated transmission technology that brings performance unmatched by standard technologies.

Bluetooth and Bluetooth Low Energy (BLE)

Bluetooth and Bluetooth Low Energy (BLE) has been widely used for body area network sensor devices running on the smallest batteries possible.


RTX has a strong technology portfolio of Wi-Fi platforms using 802.11bgn and .ac for both 2.4 GHz and 5 GHz frequency bands.

Multi-cellular roaming radio

Licensed and license-free RF technology for campus-wide networks

Ultra-Wide Band (UWB)

We use Ultra-Wide Band (UWB) radio technology in the 3.4 – 6.5 GHz frequency bands to provide precise indoor and outdoor 3D locations with a precision better than 0.5m. We also use UWB technology when there is a demand for highly reliable wireless transfer of shorter data packets by providing both the node as well as the infrastructure.


RTX has a long track record in designing and manufacturing communication modules for the US Wireless Medical band on 1.4 GHz (WMTS). RTX is also familiar with the more newly dedicated and protected Medical Body Area Network frequency band (2360-2400 MHz), which by the FCC in 2012 was designated for wearable or implanted wireless medical devices like e.g. low-cost or even disposable sensors.
