“…With a 400 MHz of total bandwidth at the 28 GHz band, downlink rates over 1.5 Gbps (with peaks up to 2.5 Gbps) have been achieved, measured from a single device located 25-160 m from the antenna [25]. Similar results are reported in other locations [26], [27]. More recently, 3 Gbps of downlink and 200 Mbps of uplink have been reported in the Verizon network (U.S.), using the newer SD X55 modem, which supports the aggregation of 8 component carriers (8CC), with 100 MHz of bandwidth each, for downlink, and up to 2CC for uplink [28].…”

5G is a key tool for the cloud-based wireless production of audio-visual contents. By providing higher throughput and lower latency than previous mobile network technologies, as well as flexible allocation of network resources, it enables that some content production pipelines, which are currently implemented using wired connectivity, are provided on top of a 5G network. This brings down production costs, reduces environmental impact and increases operational efficiency. In particular, live immersive production services, such as free-viewpoint video (FVV), can be provided in a much more efficient way. In this paper, we address the challenge of producing and streaming FVV services in real time through 5G networks. We have adapted a state-of-the-art FVV system to integrate it within a 5G architecture, using three key technological enablers: mmWave radio access network to support the uplink traffic requirements from FVV cameras, multi-access edge computing to run video processing algorithms with minimum latency, and end-to-end slicing to guarantee a sufficient quality of service (QoS) within the production pipeline. We have built a field trial over the production network of a telecommunication operator, including a mmWave pilot deployment, edge cloud processing, and remote content production, involving three different locations across Spain. We have measured the key performance indicators at the relevant parts of our trial deployment, showing that, with existing 5G technology, it is possible to achieve live FVV production, although with some limitations. We have also analyzed such limitations, obtaining some insights on how the next generation of 5G networks can overcome them to achieve higher quality of experience (QoE).

“…• SigCap [4], an Android app developed at the University of Chicago which collects Global Positioning System (GPS), time and location information along with signal and network parameters (e.g., 4G and 5G RSRP, RSRQ, RSSI, PCI, 4G frequency, etc) through Android APIs that extract this information directly from the modem chip and hence is compliant to relevant standards. Instantaneous skin, CPU and GPU temperature measurements from the APIs were added to SigCap for the results reported in this paper [10].…”

“…It is anticipated that the extremely high throughput and low latency that will be possible with 5G mmWave will support applications such as as vehicular networks, virtual reality and increased user density [1] with better Quality of Service (QoS) than the other bands. Recent -92.63 dBm measurements on deployed 5G mmWave networks in major US cities demonstrate that indeed 5G mmWave can deliver extremely high throughput in the range of 1 -2 Gbps [2], [3], [4]. These high throughputs are enabled by aggregating up to 8 100 MHz mmWave channels, depending on network and device capabilities.…”

5G millimeter wave (mmWave) cellular networks have been deployed by carriers mostly in dense urban areas of the US, and have been reported to deliver a throughput of around 1 -2 Gbps per device. These throughput numbers are captured via speed-testing applications which run for only a few seconds at a time and are not indicative of the sustained throughput obtained while downloading a large volume of data that can take several minutes to complete. In this paper we report the first detailed measurements in three cities, Miami, Chicago, and San Francisco that study the impact of skin temperature, as measured by the device, on the throughput that the device is able to sustain over many minutes. We report results from experiments conducted on deployed 5G mmWave networks that show the effect of thermal throttling on a 5G mmWave communication link when a large file download is initiated that saturates the link, i.e., the device is connected to 4 mmWave downlink channels each 100 MHz wide. We observe a gradual increase of skin temperature within 1 − 2 minutes which correlates to a decrease in the data rate due to the number of aggregated mmWave channels reducing from 4 to 1 before finally switching to 4G LTE. Finally, we identify messaging in the Radio Resource Control (RRC) layer confirming that the reduction in throughput was due to throttling due to the skin temperature rise and further demonstrate that cooling the device restores throughput performance. These results are extremely important since they indicate that the Gbps throughput deliverable by 5G mmWave to an end-user 5G device will be limited not by network characteristics but by device thermal management.

Fifth Generation (5G) mobile networks mark a significant shift from previous generations of networks. By introducing a flexible design, 5G networks support highly diverse application requirements. Currently, the landscape of previous measurement studies does not shed light on 5G network configuration and the inherent implications to application performance. In this paper, we precisely fill this gap and report our in-depth multi-country measurement study on 5G deployed at mid-bands. This is the common playground for U.S. and European carriers. Our findings reveal key aspects on how carriers configure their network, including spectrum utilization, frame configuration, resource allocation and their implication on the application performance.
