ETRI working on Small Cell Base Station in a Backpack and 5G Indoor Femtocells


Came across this slightly old news in March issue of ETRI Webzine:

Following the development of the LTE small-cell base station SW in 2016, ETRI announced on February 7 that it successfully developed a SW supporting LTE-TDD dual connectivity.

These technologies are evaluated as core technologies for future 5G communication through upgrading of conventional SW technologies, since they may be applied to buildings, stadiums, and homes.

The technologies are suitable for the locations where the traffic is rapidly increased, such as stadiums, department stores, disaster-stricken areas, and military camps. The small cells may be attached, like a wireless LAN AP, to walls inside and outside buildings, utility poles, and communication antennas, or may be carried in the form of a backpack. The research team explained that the size of the small-cell was minimized as the size of a wireless LAN AP for indoor purposes and as the size of a shoe box for outdoor purposes. The small-cell backpack weighs about 10 kg.

These accomplishments will remove the communication shadows and blind spots between cells, and will help to develop independent technologies by replacing the conventional products from other countries.

In a more recent news on this topic (September 2018):

Following the successful localization of software for LTE Small Cell, which is used in the same manner as wireless access points operating within tens of meters to 1 km, while serving as a small base station, ETRI researchers began research to localize small cell equipment essential to establishing 5G infrastructure going forward. The focus of the research is on the development of technology capable of increasing the maximum transmission speed (eMBB), which is one of the most critical criteria for 5G technology, and especially the perceived transmission speed on the user side.


According to Yonhap News (translated by Google translate):

SK Telecom will be participating in 'Intelligent 5G Small Cell Technology Development Task' together with Korea Electronics and Telecommunications Research Institute (ETRI), domestic wireless communication equipment company Teltel and U Cast. The project is sponsored by the Ministry of Science, Technology and Information and is organized by ETRI.

In this project, SK Telecom sets up requirements for small cell system development. In addition, ETRI and equipment companies provide a test environment for small cell equipment verification. ETRI develops software, and Contela and Yu Cast develop hardware.

SK Telecom and other collaborative research groups plan to open API (application programming interface) to small cell. This reduces the burden of SMEs and start-ups to develop their own interfaces.

SK Telecom and ETRI are planning to develop international standard technology and secure original patents in the small cell field based on research results.

SK Telecom announced on February 23 that it will participate in 'Intelligent 5G Small Cell Technology Development Task' together with Korea Electronics and Telecommunications Research Institute (ETRI), Kontela and U Cast of domestic wireless communication equipment. A joint research team is taking a commemorative photo in front of the first workshop at Daejeon ETRI fusion technology research and production center. 2018.8.23

SK Telecom Park Jong-kwan, director of Network Technology, said, "In the 5G era, 80% of total traffic will occur indoors." "We will take the lead in 5G technology development so that customers can fully enjoy virtual reality and hologram services."

Small Cells in BT Phone Boxes

Picture Source: Andy Sutton

In a news announcement yesterday, Vodafone said that they are planning to install 4G and 5G equipment to the underside of thousands of manhole covers across Britain to boost connection speeds in the busiest urban areas and meet the public’s insatiable demand for mobile data.

According to the report, Vodafone, which has hundreds of thousands of Cable & Wireless-branded manholes as part of its network, has developed the subterranean plan alongside Swedish telecoms equipment group Ericsson. The system is known internally as The Vault.

Attaching antenna equipment to the base of a manhole cover can boost the signal across a 200-metre radius, according to Vodafone, and could be critical in supporting future “smart city” technologies such as connected traffic lights. Installation does not require planning permission, which speeds up network build.

Vodafone and Ericsson have developed two types of system. One attaches equipment to the base of existing Victorian-era cast iron manhole covers. Another is a bespoke reinforced unit the size of a water butt that is sunk into the ground underneath a purpose-built cover.

We have blogged about Small cells infrastructure underground and in manhole covers. The following posts are related to that:
Phone boxes, which are connected to the power supply, are a useful tool to boost demand on high streets and in rural areas. Vodafone has signed a deal with BT’s wholesale division to install 4G antennas in phone boxes, and has kitted out one on Edinburgh’s Princes Street to improve coverage in time for the Hogmanay celebrations on New Year’s Eve.

The picture on the top from Andy Sutton is from Small Cells World Summit back in may. He says, "New life for old kiosks, KX100+ accommodating a 4G LTE small cell for enhancing mobile area capacity density"


ThinkSmallCell has a nice picture of the top of the KX100+ phone booth. In it's report on the Small Cells World Summit 2018, David Chambers says the following:

BT had the largest demo with a full size telephone box equipped with a small cell hidden in the roof space. Although only one Nokia small cell was fitted, the unit could accommodate several from different network operators. Each site is backhaul with either 100Mbps or 1Gbps managed Ethernet and transmits above head height using an omnidirectional antenna. It would seem we will shortly be making phone calls from telephone boxes again, just without realising it.

It would be interesting to see some more of these old phone boxes converted into small cell towers.

Turin will be the first European city with a 'drone ready' 5G network


Last year I blogged about how TIM wants Turin to be the first 5G city in Italy. Since then I have also blogged about how TIM has rolled out "commercial" 5G across the whole of San Marino.

Turin (Torino) will be the first European city with a 'drone ready' network, thanks to the use of TIM's 5G technology. Last month measurement activities of the aerial coverage at high altitude was done in Piazza Vittorio Veneto and at the Parco del Valentino and Parco Dora. "The municipality of Turin will use the drones for security and we will experiment with the municipal police remotely piloted aircraft to control some areas most at risk of safety", explains Paola Pisano, councilor for innovation of the municipality of Turin. "Do not call it Big Brother, the goal is to support men in uniform operating on the territory" he continued. via La Repubblica (translated from Italian via Google translate)

The photos above are available on TIM Newsroom Flickr channel here.

According to Mobile World Live:

Telecom Italia and its partners flew remotely piloted aircrafts using 5G to measure mobile coverage in Turin in Italy, which the operator claimed will make the city the first in Europe with a drone-ready network.

The trial was coordinated with the support of the Turin Polytechnic University and enterprise drones solution provider Seikey.

Public safety, critical infrastructure monitoring and land protection are some examples TIM gave of drone applications that will benefit from a high quality connection to send data and videos in real time.

As can be seen in one of the pictures, the equipment used for measurements is PCTEL’s flagship IBflex® scanning receiver for sub-6 GHz bands that was announced at MWC Americas 2018. Here is a tweet from them with embedded video.
