Use cases under this modality take place e.g. into hybrid operating rooms. Hybrid operating rooms (OR) are in general equipped with advanced imaging systems such as e.g. fixed C-arms (x-ray generator and intensifiers), CT scans (Computer Tomography) and MRI scans (Magnetic Resonance Imaging). The whole idea is that advanced imaging enables minimally-invasive surgery that is intended to be less traumatic for the patient as it minimizes incisions and allows to perform surgery procedure through one or several small cuts. This is as an example useful for cardio-vascular surgery or neurosurgery to place deep brain stimulation electrodes.
Due to its many benefits for the patients, image guided surgery is now the main stream for many specialties from cardiology to gastroenterology or ophthalmology. This is the underlying force for a very dynamic market predicted to reach $4,163 million by 2025 and experiencing a sustained growth of 11.2% from 2018 to 2025 (see 
But, as of now, a lack of real interfaces between technologies and devices inside operating rooms is putting progress at risk. In fact, devices and software must be able to work together to create a truly digitally integrated system in the operating room. Multiple vendors are proposing integrated OR proprietary solutions but they are often limited to their particular standpoint, depending on the category of equipment they usually provide: OR tables and lighting providers, anaesthesia and monitoring equipment, endoscopes or microscopes, medical imaging (X-Ray, ultrasounds), video monitors and streaming. No category dominates others with the capacity to impose a particular solution that could be adopted by all. This roadblock to full digitalization is addressed by standards like e.g. DICOM supplement 202: RTV which leverages on SMPTE (ST 2110 family of standards) to enable the deployment of equipment in a distributed way. The intention is to connect various video or multi-frame sources to various destinations, through a standard IP switch, instead of using a proprietary video switch. This is shown on the figure below (see 
Carriage of audio-visual signals in their digital form has historically been achieved using coaxial cables that interconnect equipment through Serial Digital Interface (SDI) ports. The SDI technology provides a reliable transport method to carry a multiplex of video, audio and metadata with strict timing relationships but as new image formats such as Ultra High Definition (UHD) get introduced, the corresponding SDI bit-rates increases way beyond 10Gb/s and the cost of equipment that need to be used at different points in a video system to embed, de-embed, process, condition, distribute, etc. the SDI signals becomes a major concern. The emergence of professional video over IP solutions, enabling high quality and very low latency performance, now calls for a reengineering of ORs, usually a long and costly process but that can be accelerated thanks to the adoption of wireless communications whose flexibility also reduces installation costs.
Witnessing the increasing interest of health industry actor in wireless technologies, 
predicts that the global wireless health market is projected to grow from $39 Billion in 2015 to $110 Billion by 2020. More specifically, 
points out the increasingly prevalence of wireless technology in hospital which has led to the vision of the connected hospital, a fully integrated hospital where caregivers use wireless medical equipment to provide the best quality of care to patients and automatically feed Electronic Health Records (EHR) systems. As a natural evolution, for wireless technologies that can cope with hospitals' difficult RF environment and can provide needed security warranties, it is expected that they can be a promising opportunity enabling surgeons to benefit from advanced imaging/control systems directly in operating rooms while still keeping the flexibility of wireless connectivity. In practice, one can also expect the following benefits from going wireless in O.R.:
Equipment sharing between operating rooms in the same hospital which makes procedures planning easier and allows hospitals to deploy an efficient resource optimization strategy,
On-demand addition of complementary imaging equipment in case of incident during a surgery procedure which eventually leads to better care provided to patients,
Suppression of a range of cables connecting a multitude of medical devices, constituting as many obstacles, that makes the job of a surgical team easier and reduces the infection risk.
In addition, hybrid O.R. trend makes operating rooms increasingly congested and complex with a multitude (up to 100) of medical devices and monitors from different vendors. In addition to surgical tables, surgical lighting, and room lighting positioned throughout the OR, multiple surgical displays, communication system monitors, camera systems, image capturing devices, and medical printers are all quickly becoming associated with a modern OR. Installing a hybrid O.R. represents therefore a significant cost, not only coming from the advanced imaging systems themselves, but also from the complex cabling infrastructure and the multiple translation systems that are needed to make all those proprietary devices communicating together. Enabling wireless connectivity in O.R. simplifies the underlying infrastructure, helps streamlining the whole setup and reducing associated installation costs.
