Specifications table

Subject area	Video transmission over cellular networks
More specific subject area	Connectivity and ability to transmit large amounts of data, e.g. real-time videostreams
Type of data	Figures, tables
How data was acquired	A test vehicle, equipped with 2 high-definition video cameras (Axis F1035, AXIS F44) and a sound unit (AXIS A8105) that were connected via a local TCP/IP network to a multi-channel modem (Viprinet 512N). The modem communicated with a hospital base station (Viprinet Multichannel VPN Hub 1020). While traveling, connectivity data were recorded on the sender side (vehicle) using Viprinet software, while the corresponding videostreams were recorded and evaluated manually on the receiver side (hospital); interruptions of videosignals from individual cameras were annotated and mapped onto the connectivity data.
Data format	Tables and figures with summary and annotations of raw data
Experimental factors	Real life transmission of videosignals from moving vehicle travelling through both city and rural areas
Experimental features	A test vehicle was equipped with two videocameras that were connected via an internal network to a multichannelmodem (Viprinet) that divided the stream onto four parallel and redundant channels. The individual streams were carried on commercial cellular networks (3/4G) from different providers and via a hub (Viprinet) on the receiver side re-combined to one single stream.

Data source location	Skåne county, Sweden (see Fig 1)
