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.

US Military in Africa Says Changes Made to Protect Troops

The U.S. military in Africa has taken steps to increase the security of troops on the ground, adding armed drones and armored vehicles and taking a harder look at when American forces go out with local troops, the head of the U.S. Africa Command said Monday.

Gen. Thomas D. Waldhauser told reporters the U.S. also has cut the response time needed for medical evacuations the result of a broad review in the wake of last year’s ambush in Niger that killed four U.S. soldiers and four of their Niger counterparts.

Since that happened, there were significant things to change and learn, Waldhauser said. We’ve done a thorough scrub really on every level, whether it’s at a tactical level … or how we conduct business at AFRICOM.

A report is due in mid-August on actions taken in response to the findings, Waldhauser said. He released a report in May on the ambush, which has been blamed on extremists linked to the Islamic State organization.

He said Africa’s challenges remain vast, from Islamic State and al-Qaida-linked groups in the west to al-Shabab in the east.

The U.S. takes a hard look at what is necessary when accompanying local forces on operations, in terms of when it’s necessary; is the threat there going against something that’s significant to the U.S. homeland and our national interests, he said.

Drones are part of the strategy to provide intelligence-gathering for partner nations so they can consider various operations and take on these threats, Waldhauser said.

The U.S. has authority to carry out drone strikes in Libya and Somalia, according to AFRICOM, but Waldhauser confirmed that we have been arming out of Niger, and we’ll use that as appropriate. The U.S. says it started arming drones in Niger earlier this year; they are currently deployed to an air base in the capital, Niamey.

He stopped in Senegal while in the region for an annual senior leader and communications symposium in Cape Verde, according to the U.S. Africa Command.

The U.S. maintains a small site at Camp Cisse in Dakar’s old airport that allows for U.S. military aircraft to land and refuel. It also allows for storage and use during crisis situations in West Africa such as the response to the deadly Ebola outbreak a few years ago or to any threats against embassies.

America’s role on the continent is to build the capacity of local partner forces, Waldhauser said.

The majority, if not all of the combat operations, will be conducted by the partner force, not by the United States. So our whole goal is to get them up to a level that they can deal with the challenges that they face, he said.

In no case are we trying to take the lead. In no case do we want to own the problem, really in all cases and various methods, whether it be kinetic strikes in places like Somalia or working bilaterally with G5 countries in the west, he said, referring to the new five-nation G5 Sahel counterterror force in West Africa.

When the U.S. does step in with strikes, we go out of our way to reach levels of certainty with whom we know we are up against, he said. Officials and residents in Somalia, however, more than once in recent months have accused the U.S. of killing civilians in drone strikes.

Waldhauser also warned that partnership with the U.S. comes with responsibility and mentioned as an example recent reports of extrajudicial killings in Cameroon. The United Nations human rights chief last week said he was utterly appalled at a recent video appearing to show Cameroonian soldiers shooting to death women with small children strapped to their backs as suspected Boko Haram extremists.

We want to have a strong military relationship with Cameroon. But their actions will go a long way toward how that will play out in the future with regards to the transparency on some of these latest allegations. Waldhauser said.

SURPRISINGLY FEW ZIMBABWEANS RETURN HOME TO VOTE IN FIRST POST-MUGABE GENERAL ELECTION

PRETORIA– The South African Department of Home Affairs )Interior) has expressed surprise at the low number of Zimbabweans who have gone through the Beitbridge border post in northern Limpopo province in the past few days to participate in Monday’s general electionm the first to be held in that neighbouring country since the forced retirement of former leader Robert Mugabe after 37 years at the helm.

There are three million Zimbabweans in South Africa and most of them were expected to go home to vote in their country’s historic elections Monday. Beitbridge is the main port of entry/departure after Johannesburg’s O.R Tambo International Airport and during the peak travel periods, especially during the Christmas holidays, more than 20,000 travellers are processed daily at Beitbridge.

Zimbabwean businessman Clever Dube, who currently lives in South Africa, was stationed at the Beitbridge border post to see if his fellow countrymen are really going home to vote. He says people are afraid of losing their jobs just to go and vote for a government they are not sure will fix its economy.

People are afraid to leave whatever they are doing rushing for a vote; they might lose whatever they are doing in terms of jobs.

Dube, a former freedom fighter and soldier in Zimbabwe, says allegations that former president Robert Mugabe and his supporters have formed a new party, the National Patriotic Front, and that Mugabe is financially supporting opposition party campaigns, made some Zimbabweans despondent to go and vote.

Those people who were in ZANU PF, the old ZANU PF, like President Mugabe and the crew, they formed the party NPF and Mugabe sponsored the (Opposition) MDC for the campaign, and we heard most of the people who are in the NPF they said once (MDV candidate Nelson) Chamisa wins the elections. some of the people from the NPF are going to be given posts. Most of the people were willingly with the MDC but now they do not have confidence with the MDC and also with ZANU PF the same applies.

Morris Jones, a shoemaker in Cape Town, wants to vote to bring about change in Zimbabwe. Things are tight in Zimbabwe, as you can see that people are running away from Zimbabwe looking for work, looking for money in other countries like South Africa, or Zambia. So we are now going for elections people don’t have work, all the companies are closed there is no money, there is nothing which is good in Zimbabwe.

Meanwhile, the Home Affairs Department Director for ports of entries, Stephen van Neel, said the department was surprised by the low number of Zimbabweans going home to vote.

We are completely surprised because the number of travellers going through Beitbridge is quite low. I mean when we look at the numbers of people who travelled through the port on Thursday and Friday we had actually less than the number of people we normally get during the week compared with last Wednesday and Tuesday. It is lower numbers. That is the same as any other day that few people move through the port into Zimbabwe to go and vote.

Eleven thousand polling stattions in Zimbabwe are expected to open at 7 a.m. on Monday. More than 70,000 police personnel have been deployed all over Zimbabwe.

Meanwhile, Mugabe says former defence minister Sydney Sekeramayi should have succeeded him. Addressing the media outside his home in the capital, Harare, on Sunday.

In Zimbabwe’s first election since Mugabe was forced to resign last November, incumbent President EmmersonMnangagwa, Mugabe’s former ally in the ruling ZANU-PF party, faces opposition leader Nelson Chamisa of the MDC.

Mugabe said he had planned to resign at the ZANU-PF congress in December last year. Let the people go and vote. Let them go and vote freely. We have had now a long list of aspirants, 23 is the number of aspirants. I must say very clearly, I can’t vote for those who have tormented me. No. I will make my choice among the other 22, added Mugabe.
