Operators need to take a holistic approach to their network and embrace the ‘power of and’ if they are to meet rising customer demand, improve scalability and reduce network complexity.
Speaking during a keynote conference session at Broadband World Forum, Federico Guillén told the conference session there is no single technology or access mode which will deliver ubiquitous ultrafast connectivity, and instead a combination of technologies is required. This is especially true if the industry is to deliver on the promise of 5G.
Those operators which don’t recognize the ‘power of and,’ he warned, could fail to meet speed and connectivity targets and lose ground to competition.
“The strategy of deploying fiber to the most economical point in the network is still valid, but the combination of fixed fiber, wireless and other access technologies is now even more crucial to the operator’s business case,” said Guillén. “Fixed networks are going to be essential for the growth of 5G, for example, as they will complement wireless for mobile transport. We will also see a combination of fiber and fixed wireless access to deliver ultra-broadband to the home using technologies such as WiGig. This convergence of fixed and wireless is one aspect of what we are calling the ‘power of and’.”
According to Guillén, the second element of this approach is delivering a gigabit experience both to and into the home. This, he continued, has been a pressure point for operators with poor in-building wiring or Wi-Fi, and can comprise more than 30% of calls to a broadband operator’s helpdesk.
“With all the focus on getting ultra-broadband to the front door, it is also important not to neglect the in-home network,” said Guillén. “Wi-Fi is a critical part of the end-to-end service, but is often the weak link. Delivering a gigabit experience both to and throughout the whole home is crucial, and we need to reach a point where end-users don’t have to think about their Wi-Fi – it’s just there.”
Guillén went on to explain that virtualization will have a key role keeping operational costs low as the network gets more complex, provided it is used in the right way.
“There is no doubt that virtualization can simplify networks, and the third ‘power of and’ is in the network and the cloud; moving hardware here makes networks easier to manage and scale,” he said. “However, virtualizing everything is not the answer. Operators must look at the business case for virtualization and identify which areas are going to provide the most value.”
Guillén’s presentation comes as Nokia launches Intelligent Access, an enhanced portfolio of access solutions to build gigabit-ready networks. This includes Software Defined Access Network (SDAN) technology and a new carrier-grade in-home Wi-Fi solution.
“The ‘power of and’ is the driving concept behind Intelligent Access. By taking a holistic approach, operators can enhance their network, deliver a gigabit experience to the end-user and make their operations faster, better and smarter,” Guillén concluded.
Kenya tool to help companies prepare for emergencies
After its team members survived last week’s Nairobi terror attack, Ushahidi decided to release a new preparedness tool for free, writes its CEO, NAT MANNING
On Tuesday I woke up a bit before 7am in Berkeley, California where I live. I made some coffee and went over to my computer to start my work day. I checked my Slack and the news and quickly found out that there was an ongoing terrorist attack at 14 Riverside Complex in Nairobi, Kenya. The Ushahidi office is in Nairobi and about a third of our team is based there (the rest of us are spread across 10 other countries).
As I read the news, my heart plummeted, and I immediately asked the question, “is everyone on my team okay?”
Five years ago Al-Shabaab committed a similar attack at the Westgate Mall. We spent several tense hours figuring out if any of our team had been in the mall, and verifying that everyone was safe. We found out that one of our team member’s family was caught up in the attack. Luckily they made it out.
At Ushahidi we make software for crisis response, including tools to map disasters and election violence, and yet we felt helpless in the face of this attack. In the days following the Westgate attack, our team huddled and thought about what we could build that would help our team — and other teams — if we found ourselves in a similar situation to this attack again. We identified that when we first learned of the attack, nearly everyone at Ushahidi had spent that first precious few hours trying to answer the basic questions, “Is everyone okay?”, and if not, “Who needs help?”
People had ad-hoc used multiple channels such as WhatsApp, called, emailed, or texted. We had done this for each person at Ushahidi (their job), in our families, and important people in our community. Our process was unorganised, inefficient, repetitive, and frustrating.
And from this problem we created TenFour, a check in tool that makes it easier for teams to reach one another during times of crisis. It is a simple application that lets people send a message to their team via SMS, Slack, Voice, email, and in-app, and get a response. It also works for educational institutions, companies with distributed staff, as well as part of neighbourhood networks like neighbourhood watches.
This week when I woke up to the news of the attack at Riverside, I immediately opened up the TenFour app.

Kia multi-collision airbags
The world’s first multi-collision airbag system has been unveiled by Hyundai Motor Group subsidiary KIA Motors, with the aim of improving airbag performance in multi-collision accidents.
Multi-collision accidents are those in which the primary impact is followed by collisions with secondary objects, such as other vehicles, trees, or electrical posts, which occur in three out of every 10 accidents. Current airbag systems do not offer secondary protection when the initial impact is insufficient to cause them to deploy.
However, the multi-collision airbag system allows airbags to deploy effectively upon a secondary impact, by calibrating the status of the vehicle and the occupants.
The new technology detects occupants’ positions in the cabin following an initial collision. When occupants are forced into unusual positions, the effectiveness of existing safety technology may be compromised. Multi-collision airbag systems are designed to deploy even faster when initial safety systems may not be effective, providing additional safety when drivers and passengers are most vulnerable. By recalibrating the collision intensity required for deployment, the airbag system responds more promptly during the secondary impact, thereby improving the safety of multi-collision vehicle occupants.
“By improving airbag performance in multi-collision scenarios, we expect to significantly improve the safety of our drivers and passengers,” said Taesoo Chi, head of the Hyundai Motor Group’s Chassis Technology Centre. “We will continue our research on more diverse crash situations as part of our commitment to producing even safer vehicles that protect occupants and prevent injuries.”
According to statistics by the National Automotive Sampling System Crashworthiness Data System (NASS-CDS), an office of the National Highway Traffic Safety Administration (NHTSA) in USA, about 30% of 56,000 vehicle accidents from 2000 to 2012 in the North American region involved multi-collisions. The leading type of multi-collision accidents involved cars crossing over the centre line (30.8%), followed by collisions caused by a sudden stop at highway tollgates (13.5%), highway median strip collisions (8.0%), and sideswiping and collision with trees and electric poles (4.0%).
These multi-collision scenarios were analysed in multilateral ways to improve airbag performance and precision in secondary collisions. Once commercialised, the system will be implemented in future new KIA vehicles.
