Huawei SkySite: Drone with 5G base station & '5G Book' RRU

One of the announcements from Huawei that seem to have missed most of the articles, magazines & analysts is their SkySite Drone with a 5G Base Station and a RRU called '5G Book'. 

Picture Source: Various, see references at the bottom

While Huawei calls SkySite as a drone with integrated 5G base station, I am assuming that the BBU (or CU in 5G) is located on the ground. The tethering is used for providing power as well as fiber for communication between the CU/DU on the ground as the '5G Book' RRU on the drone.

EE was the pioneer of these tethered drones (called Airmasts initially and E.M.M.A. later) as you can see from this video by ThinkSmallCell here.

The drone is designed for emergency coverage after a site failure due to technical issues or natural disasters like earthquakes or floods. The drone weighs just 7 kgs. Tethering allows the drone to be up for a few days. From my past experience, the limiting factor was the motors on the drone getting hot. It can still remain in air between 2-4 days.


According to Developing Telecoms:

In his introduction, President of Carrier Business Group Ryan Ding focused on the vendor’s growing role as a provider of humanitarian communications solutions by unveiling the new Huawei 5G Skysite. Using a new ‘Book’ radio unit weighing only 7 kilos, 5G Skysite is 40% lighter than the outgoing 4G Skysite. The 5G Skysite antenna is supported 100 meters above ground by a drone and the entire base station can be set up in five minutes, to give between 30-40 square kilometres signal coverage.

T-Mobile USA: Anatomy of A Mobile Wireless Network


T-Mobile has a nice educational video on what makes a network looking at backhaul, small cells, etc. I have posted about T-Mo small cells here and here before. I have also pointed out that the definition of Small cells varies from country to country and USA is no exception. In the USA, RRH's are often referred to as small cells due to their small form factor but I disagree. You can see this earlier post on Macrocells, Small Cells & Hetnets Tutorial.

Here is the video on the anatomy of a mobile wireless network.

Turkcell Marks a 'First in the World in 5G' with Domestic Drone Technology

Press release from Turkcell (translated from Turkish to English by Google translate):

Turkcell continues to undertake firsts in the scope of its 5G works. Huawei Turkey and Aviation Lapis Technologies R & D engineers working with Turkcell team has now spent on a different solution in drone technology life. In this work, which is a first in the world, Turkcell successfully completed the trial flights of the domestic drone, which is controlled by 5G and capable of transferring 360 degree 4K images to live virtual reality glasses.

Carrying one step further studies in 5G Turkcell, Huawei Turkey R & D center and domestic drone manufacturers Lapis Aviation Technology, in cooperation with Turkey's first experienced live virtual reality experience through 5G technology has scored the indigenous drones. The drone, which successfully completed the test flights, is controlled by 5G. Thanks to this innovative application, which provides real-time high-speed data transfer over 5G technology, Turkcell became the first operator in the world to implement this solution in line with 3GPP standards. This solution, developed by Turkcell with its business partners, eliminates the distance between pilot and drone thanks to low delay connection and 5G coverage.

Turkey's first 3.5 GHz frequency band can be controlled through the 5G technology provided through Turkcell 5G Drone, 360 4K camera in live images still virtual reality to the viewers in different locations through 5G (VR) offers the opportunity to watch the spectacle. Thanks to this solution, which brings a new dimension to drone applications, it is possible to control the oil and gas pipelines in the industrial area and to carry out operations such as the control of the fields in the agricultural sector in a safer, faster and economic way. In addition, thanks to the 360-degree 4K image-forwarding capability, new experiences can be offered to the entertainment industry by providing concerts or other shows to be transmitted to virtual reality glasses.
...


Today, because the drones are controlled via Wi-Fi, the communication distance between the drone and the pilot can be reduced to 500 meters, especially in crowded cities. Thanks to the 5G technology that enables low-delay connection and high-speed data transmission, the Turkcell 5G Drone can be controlled with a high-resolution 4K image without a distance limit. In addition, increasing the number of commercial drones flying at low altitude is also a very important need to manage air traffic. With this technology, which will contribute to the management of air traffic, commercial UAVs and drones will increase their use in many sectors such as transportation, logistics, security, monitoring and media.

Last year we blogged about South Korean operator KT and separately, Japanese operator KDDI doing something similar. See here.

Sprint's Trebl: Magic Box + Alexa + HiFi Speakers


Sprint's award winning MagicBox that we have written about multiple times in this blog has launched a new product called Trebl that contains indoor Magic Box small cell, integrated Amazon Alexa voice capabilities and Harman Kardon sound quality.

According to Electronics 360:

The TREBL with Magic Box, introduced this week at CES 2019, won a CES Innovation Award in the Smart Home product category. TREBL is a wireless small cell that accelerates LTE data coverage and speed while controlling smart home devices using Amazon Alexa. The small cell can also play music with Harman Kardon audio through two 8 W speakers, an embedded amplifier, three built-in far-field microphones, Bluetooth, and noise and echo cancellation.

The TREBL with Magic Box is water-resistant, making it suitable for both indoor and outdoor use, and it is lightweight for portability.

And it has been nominated for MWC 2019 Glomo award too



While we love the style, we are not exactly sure why someone would need this combination of Magic Box and Alexa. We will wait and see if it succeeds. In the meantime we wish Sprint the best of luck for Glomo awards.

Dense Air: The Neutral Host Small Cell Wholesale Network Operator


Dense Air was launched at MWC 2018 as a new wholesale network operator, that “enhances and extends” the coverage and capacity of existing Mobile Networks as a “Carrier of Carriers” operator, typically on a neutral host basis.

According to the announcement:

Dense Air uses Airspan’s comprehensive portfolio set of 4G and 5G small cells to offer services to Mobile Operators in licensed spectrum dedicated to small cells for densification/extension deployments.

According to Paul Senior, Acting CEO of Dense Air, “By adding small cells, running in dedicated licensed spectrum to Macro networks at cell edge either outdoors or indoors, we can dramatically improve the service experience to end users, increase speeds and network capacity. Importantly, Dense Air does not and will not offer retail mobile services and does not compete in any way with mobile service providers.”

“The economics of both 4G and 5G small cell deployments can be dramatically improved when deployed using a neutral host solution, i.e. when a single network of small cells can host multiple operators. Our mission is to help MNOs and MVNOs improve their networks by densification without the need to spend CAPEX”.

Interested readers can refer to earlier posts about Airspan's Magic Box and their deployment in Reliance Jio.

According to the website, Dense Air now has spectrum in following countries:
  • Dense Air Ireland: Operating in 3.6GHz (Band 42 & 43)
  • Dense Air Belgium: Operating in 2.6GHz (Band 38)
  • Dense Air Portugal: Operating in 3.6GHz (Band 42 & 43)
  • Dense Air New Zealand: Operating in 2.6GHz (Band 7 & 41)
  • Dense Air Australia: Operating in 3.6GHz (3GPP Band n77 & n78)

Their most recent win has been the spectrum win in the six largest Australian cities, by participating in the ACMA 5G Spectrum Auction. The acquired spectrum supports 5G operation in 3GPP bands n77/n78.

So what exactly is Dense Air and what do they do? As per their launch press release:

Dense Air is an optimised network densification and network extension service.
  • Solution delivered using Indoor and Outdoor Small Cells
  • Service operates in licensed, dedicated spectrum
  • Dense Air small cells provide services on a “Neutral Host” basis
  • We support 4G LTE and LTE Pro networks and later 5G NR
  • Dense Air fills coverage holes and capacity weak spots in Macro Networks
