Huawei to deploy high-speed internet in Northern Canada

Written on Thursday, 25 July 2019 05:39

Tech titan Huawei has revealed its plans to deploy high-speed wireless internet in a number of remote, underserved communities in the North of Canada.

The Chinese tech firm has planned to deploy mainly 4G technology. This comes amid Huawei and the US’s controversial relationship. The US has imposed sanctions on the company as they have deemed the company a potential threat to their national security. Also, Canada and China are still in the midst of a diplomatic crisis concerning the detention of a Huawei executive.

Huawei has revealed that it will partner with Ice Wireless and Iristel to ensure that the rural communities will be connected by 2025. They also stated that alongside the remote areas of northeastern Quebec and Newfoundland & Labrador, around 25 communities in Nunavut territory would also benefit from the deployment.

“We strongly believe that everyone should be connected to 4G LTE, no matter where they live in Canada, even in areas where high-speed service may not be economically viable,” said President of Huawei Canada, Eric Li.

Huawei officials have stated that they will deploy wireless internet in some of the coldest places on earth, which are located in Canada.

VP of Ice Wireless and Iristel, Jean-Francois Dumoulin, said, “We need to use highly reliable, world-class equipment to minimize physical intervention and to avoid outages that risk making our communities isolated once again. That’s why we partner with Huawei Canada.”

In fact, this comes as the US has been pressuring its allies to avoid using Huawei to deploy their 5G networks and have claimed that Huawei has links to the Chinese government and may partake in cyber-espionage on their behalf. However, there has been no proof of this allegation being true.

Also, Canada and Huawei have also been at odds due to the arrest of Huawei’s Chief Financial Officer Neng Wanzhou, in December in Canada at the request of the US. Washington believes that she committed fraud by violating Iran sanctions and lying to US banks about it, which is why they want to put her on trial for fraud charges.

Vodafone Group’s Networks Centre of Excellence team and the Huawei Mobile Innovation Centre have been testing a way to help address spectrum constraints in Turkey. The teams have completed the world’s first trial of GSM/LTE (GL) 900MHz dynamic spectrum sharing on Vodafone’s commercial networks in the Black Coast city of Trabzon.

"Spectrum is an extremely precious asset. This new network optimization technique improves spectral efficiency and enhances the experience of Vodafone customers,” said Mallik Rao, Vodafone Turkey’s Chief Technology Officer.”

Last year Vodafone and Huawei achieved overlap by GSM (2G) and LTE (4G) services within the 900 MHz spectrum band. Now the companies have shown that it is possible to assign that spectrum dynamically i.e. available 900 MHz can be allocated between 4G and 2G services based on customer demand.

In the trial, which took place over several months, dynamic sharing allowed Vodafone Turkey to provide up to 10MHz of 4G capacity and throughput in a very effective way. 4G KPIs show the improvement in network performance and better user experience. The test cases showed that download and upload throughput improved by 20 percent.

Ying Weimin, President of Huawei Wireless Network Research & Development, said: “We are glad to have tested GL 900MHz dynamic spectrum sharing on Vodafone Turkey’s commercial networks, and to have achieved satisfying performance results in the past few months. Huawei is dedicated to offering technical innovations to secure our customers' business success.”

Super storms draw attention to critical communications

Written on Tuesday, 03 October 2017 12:46

The US Territory of Puerto Rico was recently hit by the strongest storm in almost 90 years. Knocking out the island’s electricity grid, 90 percent of cell phone sites stopped working, according to the US Federal Communications Commission. The recent string of monster storms in North America has drawn attention to the importance of critical communications and promoting public safety.

In the space of two months (August and September 2017), the southern United States and Caribbean region were slammed by three mega storms: Hurricane Harvey, Hurricane Irma and the most recent Hurricane Maria. Harvey caused at least 75 confirmed deaths; 1 in Guyana, and 74 in the US. As of September 27, Irma caused at least 124 deaths; while as of October 1 Maria caused at least 68 deaths.

Still recovering from Irma two weeks prior, approximately 80,000 people in Puerto Rico were left without power after Maria hit. Puerto Rico Electric Power Authority (PREPA) had struggled with increasing debt, reaching $9 billion even before the hurricanes, prompting them to file for bankruptcy. The island’s aging infrastructure left it vulnerable to damage from the storms. Consequently, mobile coverage was cut off.

When Maria finally subsided, in Puerto Rico’s capital, San Juan, cars were reportedly pulling up on the side of roads with occupants emerging holding their cell phones up in the air in search of network coverage. For miles, cell phones displayed a frustrating “No Service” message. This is in stark contrast to the US states of Texas and Florida that had cell service restored almost completely in storm-affected areas a week after Harvey and Irma hit.

The aftermath of the storms has drawn fresh attention to the importance of critical communications. Following the storms, the United States Federal Communications Commission urged Apple to activate the FM (frequency modulation) chips that are in iPhones to promote public safety.

Commission Chairman Ajit Pai released a statement applauding those companies that have “done the right thing” by activating FM chips in their phones in light of natural disasters hammering the country. “In recent years, I have repeatedly called on the wireless industry to activate the FM chips that are already installed in almost all smartphones in the United States,” said Mr. Pai.

He highlighted the importance of FM chips during natural disasters. When wireless networks go down during a disaster, smartphones with activated FM chips can allow people to get vital access to important information without an internet connection. “Apple is the one major phone manufacturer that has resisted doing so,” said Mr. Pai. “But I hope the company will reconsider its position, given the devastation wrought by Hurricanes Harvey, Irma, and Maria.”

According to the FCC, 89.3 percent of cell sites were out of service after Maria. All counties in Puerto Rico, except San Juan, had greater than 75 percent of their cell sites out of service. 29 out of the 78 counties in Puerto Rico had 100 percent of their cell sites out of service. On the US Virgin Islands, 69.8 percent of cell sites were out of service.

Since there were widespread power outages in Puerto Rico and the US Virgin Islands, the FCC received reports that large percentages of consumers were left without either cable services or wireline service (one company reported that 100 percent of its consumers were left out of service due to lack of commercial power).

In one of the few places that had connectivity on Puerto Rico, the Sheraton Puerto Rico Hotel & Casino, tourists reportedly overwhelmed the lobby to use the working cell service and Wi-Fi to connect with the outside world. With a cell phone penetration rate of nearly 100 percent, according to government data, Puerto Ricans have been heavily impacted by the lack of network services on the island.

Confidence in connectivity

Puerto Rico has five main mobile operators: AT&T, T-Mobile, Claro, Sprint and Open Mobile. Connectivity provided by operators is the backbone of relief efforts today. AT&T and Sprint both dispatched teams to restore coverage to the island. The companies also waived certain fees for customers to establish a way for people to contact their families and friends.

The electric grid fallout presented one of the biggest challenges to restoring connectivity to the island. “Power is essential to restoring wireless and wireline communications. Given the breadth of power outages across the islands, we’re deploying portable generators as quickly as allowed,” AT&T said.

Social media giant Facebook also pledged support for Puerto Rico. CEO Mark Zuckerberg announced $1.5 million in aid to organizations assisting in the island’s recovery from Maria, together with direct assistance from Facebook’s connectivity team in an effort to get people back online. The company also said it would donate Facebook ad space to share critical information with Puerto Rican users.

Facebook’s connectivity team previously came under the spotlight for ambitious technology initiatives like the Aquila drone, a high-altitude solar-powered aircraft designed to connect remote areas to the internet. Facebook is pushing forward with the Aquila program's progress to help bring the world closer together through connectivity.

“Communication is critical during a disaster,” Zuckerberg said in a post after Hurricane Maria. “With 90 percent of cell towers on the island [Puerto Rico] out of service, people can't get in touch with their loved ones -- and it's harder for rescue workers to coordinate relief efforts.”

Recovery efforts have suffered in Puerto Rico as a result of its cell network outage. Utilizing social media proved immensely effective after fallout from Harvey in Texas, as people could publish posts that were quickly relayed to rescuers. Due to the lack of connectivity on Puerto Rico, in some remote areas people resorted to painting “Help” signs on roads and buildings, hoping that relief efforts would reach them.

The public safety community has long called for mobile broadband to support its mission to save lives. With the adoption of LTE mobile broadband technology, public safety networks can benefit from the advantages of fast and reliable broadband data and real-time video services, opening up new communications possibilities for rescue missions and disaster recovery situations.

In an effort to make mission-critical mobile broadband a reality, Nokia, for example, has a dedicated comprehensive technology and services portfolio called ViTrust. The portfolio includes rapidly deployable solutions for emergency and disaster recovery situations to establish coverage in remote areas, among other features.

The Finnish company recently expanded the portfolio with new services to help first responders take advantage of reliable and secure high-performance applications on their public safety devices. The services provide trouble-free continuity of operations for public safety agencies across a multi-vendor, multi-technology mission critical communications environment.

‘Care for public safety’, for instance, is a service Nokia introduced to ensure that the most demanding communications needs to public safety organizations are fulfilled. The company says it ensures that new network functionality and services interworking with multivendor LTE networks are available from day one.

One European operator is already using this service and seeing the benefits of reduced operational downtime risks, according to Nokia, with service levels stabilizing faster than before and fulfilling public safety requirements.

“The success of moving to broadband-based critical communications requires deep technological and operational expertise,” said Asad Rizvi, head of Nokia's global business development in Global Services. “Nokia has both, from our long history of working with agencies to our global service expertise in broadband.”

The public safety LTE market is expected to be valued at US$3,091.3 million by 2023, according to new market research published by MarketsandMarkets, growing at a compound annual growth rate of 25.7 percent from US$782.9 million in 2017. The factors that are driving the growth of this market, according to the report, are the rising demand for unmanned operations and remote surveillances, and elimination of connectivity issues between networks.

Nokia is to completely modernize the nationwide LTE network for Ukkoverkot, the Finnish private network operator offering wireless data communications services for infrastructure operators, the industrial IoT market, public safety authorities, the maritime industry and both residents and enterprises in remote areas.

The new network will be powered by Nokia's leading LTE solution, which provides superior network quality, capacity, security and reliability required for such specialized use cases.

"Ukkoverkot is totally focused on serving our customers, for whom connectivity means the world,” said Mikko Uusitalo, CEO of Ukkoverkot. “The agreement with Nokia enables us to roll out the most advanced public protection, IoT and campus network functions as they are available. The agreement with Finavia to develop their airport infrastructure on Nokia technology is clear testimony to the potential we have."

Founded in 2014, Ukkoverkot operates its own LTE-based mobile data network and a number of local private LTE networks, offering fast connections using the 450 MHz and 2.6 GHz spectrum bands.

Ukkoverkot's low-frequency nationwide network is largely reserved for the use of its industrial and public safety customers, which helps ensure exceptional network stability and reliability, while its high frequency network is reserved for private micro-operator networks. As a pure broadband operator, Ukkoverkot's network exclusively carries data services.

Starting in Q4 2017, Nokia will upgrade Ukkoverkot's older-generation network technology to Nokia's state-of-the-art LTE-based solution, which significantly improves network performance. This enables Ukkoverkot's customers in industrial IoT settings to capitalize on opportunities related to new Industry 4.0. applications, while critical communications and public safety operators can benefit from ultra-reliable, high-bandwidth services supporting all standardized public safety features.

Due to better propagation characteristics, low-band spectrum can provide a larger coverage area than high-band spectrum, which makes Nokia's 450 MHz LTE network solution ideal for delivering services in sparsely populated areas such as the Nordic countries.

This agreement highlights Nokia's growing momentum around the delivery of critical communications networks for customers outside of the traditional communications service provider market. Large industrial and public sector organizations are seeking robust, reliable and highly resilient networks to support services on which - in some cases - lives depend, and Nokia's solutions are ideally suited to addressing this challenge.

"With their LTE network based on Nokia's wide portfolio of technologies, Ukkoverkot brings the benefits of broadband data to the reach of new customer segments such as the industrial IoT market and public safety authorities,” said Thorsten Robrecht, head of Advanced Mobile Network Solutions at Nokia. “We are proud to team up with Ukkoverkot in its network modernization to ensure these customers can benefit from first-class network quality, and to prepare them for the services enabled by future 5G networks."

Russia’s MegaFon shows strength and denies CEO rumors

Written on Wednesday, 13 September 2017 06:37

MegaFon, one of Russia’s leading telecom providers, posted positive results for Q2 2017, with revenue up 13.9 percent year-on-year (y-o-y) to reach RUB 89,689 million. OIBDA increased by 15.8 percent y-o-y to reach RUB 34,236 million. The company has denied recent press speculation regarding the possible resignation of its CEO Sergey Soldatenkov.

In an effort to reassure its shareholders, MegaFon said recent reports and media speculation published in Russian business daily Vedomosti on the possible resignation of the company’s CEO are inaccurate. Sergey Soldatenkov has the “full support” of the board of directors, the company said in a press release, who have been “encouraged by a number of improvements in performance.”

“Shareholders are satisfied with the company’s development and support the management and specifically Mr. Sergey Soldatenkov,” said Mr. Streshinsky, Chairman of the Board of Directors at MegaFon. “Competent implementation by the company’s management of the new strategy made it possible to turn around negative sector trends in 2Q 2017, and the situation in the company’s business and on the market has shown the first signs of improvement.”

According to the press release, the Board of Directors is looking forward to Mr. Soldatenkov “leading the company forward in implementation of its 2020 development strategy.” In May, MegaFon announced a new strategy for its development over the next three years, to transform from a traditional telecom operator into an integrated digital services provider.

In terms of financials, Mr. Soldatenkov said the company has “reached a turning point where we see signs of recovery in our overall mobile revenue which has been declining during the previous quarters.” Mobile data and VAS services were the strongest revenue drivers, he said, as customers “continue to recognize the high quality of our 4G/LTE network.” MegaFon is also focused on increasing efficiency and improving margins, he added.  

In August, MegaFon became one of the first operators in Europe to launch a commercial Gigabit LTE network in partnership with Nokia. The peak data download speed reached 979 Mbps using Nokia Air Scale. The test was conducted using Sony’s Xperia XZ Premium smartphone, using the Qualcomm Snapdragon X16 LTE modem, which was the first commercial mobile device in Europe which supports Gigabit LTE.

Nokia Flexi Multiradio modules were used as the base station, which are equipped in most of the sites of the Moscow MegaFon branches, and the Nokia AirScale system module is already in place in order to support the path to 5G.

The demonstration, according to Nokia’s vice president, Eastern Europe, Demetrio Russo, was “another important step towards the launch of MegaFon’s 5G network.”

Russo noted that Nokia was “excited by the cooperation involved in this project, the successful implementation of which will make it possible for MegaFon to offer its subscribers a unique experience of using modern broadband services during the transition to 5G.”

In June, during the Saint Petersburg Economic Forum, together with Huawei, MegaFon demonstrated the operation of a 5G network at 35Gbps, achieving what was then the absolute record in Russia for mobile internet speed.
