HAPSMobile - Bringing Connectivity from the Sky for Unserved Areas & Emergencies


Back in April SoftBank announced the launch of a High Altitude Platform Station (HAPS) business through HAPSMobile, a joint venture between SoftBank and US-based company AeroVironment, Inc. With the aim of constructing a HAPS system that delivers telecommunications network connectivity from the sky for a global business, HAPSMobile developed “HAWK30,” an unmanned aircraft for stratospheric telecommunications platform system that flies at altitudes of approximately 20 kilometers.

HAPS refers to systems where unmanned objects such as aircraft flying in the stratosphere can be operated like telecommunication base stations to deliver connectivity across wide areas. By utilizing HAPS, SoftBank will be able to build stable Internet connection environments at locations unserved by telecommunication networks, such as mountainous terrain, remote islands and developing countries. Furthermore, by efficiently interconnecting with current telecommunication networks, SoftBank will be able to realize wide-area connectivity that spans both the sky and the ground to enable drone utilization, as well as contribute to the adoption of IoT and 5G. Since HAPS can provide stable telecommunications networks without being affected by situations on the ground, the technology is also expected to help assist rescue and recovery efforts during times of disasters.

“HAWK30”, the unmanned aircraft for stratospheric telecommunications platform developed by HAPSMobile, measures approximately 78 meters long. Powered by solar panels on its wings that house 10 propellers, “HAWK30” can fly at speeds of approximately 110 kilometers per hour on average. Since “HAWK30” flies at high altitudes above the clouds, its solar panels are continually powered by sunlight. “HAWK30” can also be flown for long periods that range up to a number of months since it takes advantage of the stratosphere's climate, which sees winds that are relatively gentle year-round.

The IEEE Article points out:

Nobody expects the high-flying Loon balloons and HAPSMobile’s drones to compete directly with ground-based 5G networks in the near future. Until recently, it hasn’t been easy to develop a balloon or drone platform that is cost-effective enough to even consider using for telecommunications, said Salvatore Candido, principal engineer at Alphabet and CTO of Loon. But such high-flying platforms may help fill the gaps when coverage is lacking in rural or otherwise under-served communities. (Even rural parts of the United States may miss out under current 5G network deployment plans.)

Fleets of balloons and drones could also provide coverage on a temporary basis, such as during a major pre-planned event like the Super Bowl or in the wake of a natural disaster. Nokia previously partnered with Alphabet’s Loon when the latter deployed its experimental balloon fleet to provide basic Internet service to 200,000 people in Puerto Rico after the U.S. island territory was left devastated by Hurricane Maria in 2017. The balloons carried LTE technology from Nokia as part of a broader coalition involving AT&T and T-Mobile.


In a blog post I did couple of years back, I detailed how I was involved in trialling small cells on Helikite with EE (BT). The intention was the same. Provide coverage in rural / remote areas and in case of  disasters and emergency. There, we used the small cells as relays to backhaul on macros far away and in theory, the concept can be extended with mesh links to provide connectivity between helikites. It's all detailed here, here and here.

High-level Architecture Introduction of Mobile Cellular Networks from 2G to 5G

IEEE 802.11be Extremely High Throughput (EHT), a.k.a. Wi-Fi 7

We have been writing about Wi-Fi for a long time, weather it's to do with indoor connectivity , competition with 5G or just a name change to something simpler. When we last wrote about WiFi 6, a.k.a. 802.11ax, we were expecting a quick adoption of the technology in the industry. We are still not there yet.  You know what's strange? None of the new @madebygoogle gadgets from yesterday support Wi-Fi 6. Not the Pixel 5, not the Pixel 4a 5G, not the Nest Audio, and not the new Chromecast. pic.twitter.com/QtJ8iB9FeO — Ry Crist (@rycrist) October 1, 2020 Take for instance the new iPhone 12 supports Wi-Fi 6 in all their models as one would expect but none of the new Google Pixel phones (4a, 4a 5G and 5) support it. In fact none of the new Google devices support it. Which is rather bizarre. While we are still looking forward to Wi-Fi 6 becoming widespread, IEEE has already started working on the successor of 802.11ax, 802.11be - Standard for Information technology--Telecommunicati

CSI-RS vs SRS Beamforming

In an issue of Signals Flash by Signals Research Group (SRG), they talked about 2 different types of MIMO. Quoting from their journal, "CSI-RS versus SRS. Those operators that have tested or made token use of MU-MIMO leverage a flavor of MU-MIMO that is based on CSI-RS. The MU-MIMO network we tested was based on SRS, which makes it far more likely to observe sixteen spatial layers (versus eight)." I reached out to Emil Bj√∂rnson, Visiting Professor at KTH Royal Institute of Technology and Associate Professor at Link√∂ping University to see if he has explained this in any of his videos. Here is what he said: " I'm not talking about 3GPP terminology in any of my videos. But you can listen to the slides that starts around 12:40 in this video (embedded below) . If you are looking for CSI-RS vs SRS based MU-MIMO, then jump to around 12:40 in this video where you can see CSI-RS being referred to as "grid of beams" and SRS is similar to the other option, which is t
