Ammbr Reveals Technology For Long-Range Wireless Connectivity Up To 8 km

SINGAPORE, July 31, 2018 /PRNewswire/ — The Ammbr Foundation released details on the long-range wireless technology that will make the Ammbr mesh router capable of picking up signals from up to eight kilometers (5 miles).

The Ammbr Wi-Fi router being tested to communicate with other Ammbr routers kilometers away.

The Ammbr foundation intends to help connect the 4.1 billion people who don’t have Internet connections, through the implementation of innovative technology that allows improved connections in rural areas and over longer distances. The key, according to Derick Smith from Ammbr, is tapping into unused frequencies known as television white space (TVWS).

TVWS technology can operate in conditions where line-of-site is not possible due to obstructions such as vegetation and walls, and theoretical calculations show that a 600-megahertz TV white space signal can cover 16 times as much area as a 2.4-gigahertz Wi-Fi signal. The technology will allow Ammbr routers to extend their range up to 8 km, provide a much wider coverage footprint and allow the devices to reach neighbouring routers in areas not possible before TVWS.

TVWS exists due to a lack of use of the full set of terrestrial TV channels available and to protect television broadcasters from interference caused by adjacent analogue TV transmitters using the same channels. As stations transition to more spectrally efficient digital television, many of these broadcast bands will remain vacant and will be available for broadband use. In Africa, many rural areas have close to 100% TVWS spectrum available which makes these areas an ideal candidate for TVWS.

TVWS is part of a wider movement of Dynamic Spectrum Access technologies that seeks to more efficiently make use of spectrum that is only licensed nationally to primary users by allowing secondary users to access the primary spectrum where it is not used in specific regions or at a specific time. Access to TVWS spectrum is made possible by using a geolocational spectrum database that checks what channels a TVWS base station can use at its specific GPS position without causing any interference to neighbouring television receivers.

The UHF band used by TVWS is the sweet spot of the radio frequency spectrum that terrestrial broadcast television has been sitting on for over 60 years – TVWS has finally provided the solution to access this critical high value spectrum for broadband access. Although TVWS trials have been running since 2008 in 20 countries, currently only the USA, the UK, Singapore and South Africa have finalized TVWS regulation. It is hoped that the recent approval of TVWS in South Africa in 2018 will create the catalyst for regional approval of TVWS across Southern Africa – possibly even creating a regional TVWS geolocation spectrum database.

The TVWS spectrum lets Ammbr owners install the routers to connect to the Ammbr network in varied terrain, from dense vegetation to mountainous regions, and up to 8 km away from other Ammbr routers. This is critical in rural communities with low population densities – a key demographic where the last mile is often too costly for operators using cellular technology.

Last week, Ammbr released the demo version of the fully integrated Wi-Fi, television white space (TVWS) and blockchain capable routers – a first of its kind. These routers will be used in a series of trials around the world in places such as Cape Town, South Africa (where a TVWS regulatory framework was published in April) and parts of the United States as well as Europe

Ammbr Research Labs’ (ARL) David Johnson, who has been involved in the efforts to draft these regulations and carried out R&D and trials for the past six years together with the dedicated CSIR TVWS team, described TVWS as “the elusive promise to bridge the global connectivity gap”.

Japanese Gov’t, Japan World Expo 2025 Committee Beefing Up Bidding Activities to Host World Expo 2025

– Bringing Public-Private Sectors and Pokemon Together Ahead of Decision on Host Country in November –

TOKYO, July 31, 2018 /PRNewswire/ — The Government of Japan and the Japan World Expo 2025 Committee (hereinafter “the Committee”) have been conducting activities at home and abroad seeking to host the World Expo 2025. From July 21, the Committee took the initiative to begin an event-oriented campaign in which Pokemon, one of the Committee’s “Special Envoys (Mascot Characters),” boosts bidding activities at the Pokemon Center Mega Tokyo in Ikebukuro and elsewhere in Japan as part of efforts to win the bid to host the World Expo.https://kyodonewsprwire.jp/prwfile/release/M105049/201807256312/_prw_PI1im_lo8G2q8J.jpg

The campaign website “Pokemon EXPO Type Check” was launched in June to help people support the bidding activities together with Pokemon, and “original goods featuring Pokemon and the World Expo bid” began to be distributed from July 21 in the second phase of the campaign. In Japan where summer vacation already started, many people, mainly children and young people, flock to 26 Pokemon Centers/Pokemon Stores (facilities to offer information on Pokemon and sell Pokemon-themed goods) across the country every day where original goods are distributed.

The Pokemon Center Mega Tokyo in Ikebukuro, one of the campaign venues, was crowded with smartphone-carrying children and Pokemon fans from Japan and abroad.

As for “Pokemon EXPO Type Check,” each visitor is diagnosed as one of the designated types after answering 10 questions about Pokemon and the World Expo. Then, each visitor can receive an original photograph (a supporter’s certificate) taken together with Pokemon which varies from one type to another. Fifty-four Pokemon appear in the type check, allowing visitors to be excited about which Pokemon picture he or she can get.https://kyodonewsprwire.jp/prwfile/release/M105049/201807256312/_prw_PI3im_eAp67LKF.jpg

This campaign is designed to help people enjoy supporting Japan’s bid to host the World Expo together with Pokemon. In fact, it is not only enjoyable but constitutes an activity with social significance. As its rationale for hosting the World Expo, Japan is committed to contributing to the Sustainable Development Goals (SDGs) adopted by the United Nations General Assembly. Each supporter’s certificate of “Pokemon EXPO Type Check” lists the outcome of diagnosis as one of the goals. In short, visitors can touch on the World Expo and the SDGs through Pokemon while having fun, constituting important educational activities on social issues for young generations.

As the host of the World Expo is decided in November this year, each candidate country’s campaign is entering the final stretch. To contribute to achieving the SDGs, Japan, setting out the theme of “Designing Future Society for Our Lives,” has broached the idea of making the World Expo work toward solving problems faced by countries of the world rather than developing itself. To realize the SDGs’ concept of “inclusiveness,” Japan is conducting bidding activities involving not only the Government and business people but also the general public, including children and young people. Pokemon, which is popular among young people who have never experienced a World Expo, and a famous entertainer in Japan have become “Special Envoys” to serve as a bridge between state-level goals and grass-roots level interests.https://kyodonewsprwire.jp/prwfile/release/M105049/201807256312/_prw_PI4im_C32ueACf.jpg

If Japan wins its bid to host the World Expo, it will be the first such event to be held in Japan in 20 years since Aichi Prefecture hosted the World Expo 2005. The World Expo 2025 will attract attention not only from neighboring countries but from around the world with the help of Pokemon’s power.
