New USB standard doubles up

Published

on

The USB Promoter Group has announced the pending release of the USB4 specification, a major update of USB architecture that builds on the existing USB 3.2 and USB 2.0. It doubles the bandwidth of USB and enables multiple simultaneous data and display protocols. The USB4 architecture is based on the Thunderbolt protocol specification recently contributed by Intel.

The new USB4 architecture defines a method to share a single high-speed link with multiple end device types dynamically. This ensures that the connections best serve the transfer of data by type and application. As the USB Type-C connector has evolved into the role as the external display port of many host products, the USB4 specification provides the host the ability to optimally scale allocations for display data flow. Even as the USB4 specification introduces a new underlying protocol, compatibility with existing USB 3.2, USB 2.0 and, Thunderbolt 3 hosts and devices are supported; the resulting connection scales to the best mutual capability of the devices being connected.

“The primary goal of USB is to deliver the best user experience combining data, display and power delivery over a user-friendly and robust cable and connector solution,” said Brad Saunders, USB Promoter Group Chairman. “The USB4 solution specifically tailors bus operation to further enhance this experience by optimizing the blend of data and display over a single connection and enabling the further doubling of performance.”

Key characteristics of the USB4 solution include:

  • Two-lane operation using existing USB Type-C cables and up to 40 Gbps operation over 40 Gbps-certified cables
  • Multiple data and display protocols to efficiently share the total available bandwidth over the bus
  • Backward compatibility with USB 3.2, USB 2.0 and Thunderbolt 3

With over 50 companies actively participating in the final stages of review of the draft specification, the USB4 specification is on track to be published around the middle of 2019. Coincident with the release of the USB4 specification, the release of an updated USB Type-C Specification will be made to comprehend USB4 bus discovery, configuration and performance requirements.

USB Developer Days 2019, in the second half of this year, will include detailed technical training covering the USB4 specification and the latest for USB Type-C, USB Power Delivery, and other exciting topics.

This update is part of the USB performance roadmap and is specifically targeted to developers at this time. Branding and marketing guidelines will be established after the final specification is published.

“Releasing the Thunderbolt protocol specification is a significant milestone for making today’s simplest and most versatile port available to everyone,” said Jason Ziller, general manager of Client Connectivity at Intel. “By collaborating with the USB Promoter Group, we’re opening the doors for innovation across a wide range of devices and increasing compatibility to deliver better experiences to consumers.”

“USB4’s high throughput and advanced features enable new scenarios in consumer, enterprise, and intelligent edge markets, while maintaining interoperability with existing USB and Thunderbolt 3 devices,” said Roanne Sones, Corporate Vice President, Microsoft OS Platforms. “We are excited to work with our partners in the ecosystem to bring USB4 to market and showcase its benefits.”

Broadband gets a helping hand

Behind this week’s news that MTN fibre provider Supersonic has launched a fixed LTE service is an effort to rethink home connectivity, writes ARTHUR GOLDSTUCK

Published

on

This week, MTN made its biggest play yet into the market for fibre connections to homes, but its biggest impact may well be within the home.

The mobile operator’s fibre-to-the-home subsidiary, Supersonic, launched a Fixed LTE offering on a month-to-month basis, meaning that homes in areas not yet wired for fibre can receive high-speed broadband. More important, they can get that access at rates that seem unprecedented for mobile data. 

There are two differences from regular packages, however. For one thing, the SIM card that comes with the package only works in specific routers that have to remain plugged into a power supply. For another, the data allocation is split half-half between regular hours and a Night Owl timeframe: the hours between midnight and dawn.

“It just needs users to adjust their internet behaviour a little,” says Calvin Collett, MD of Supersonic. “Conducting massive mobile phone updates or downloading an entire library of Netflix content shouldn’t be prioritised during the day, but should be scheduled for Night Owl data consumption.”

The biggest benefit, aside from pricing, is that one does not have to wait for fibre to arrive in a specific area. While Supersonic’s core business is fixed-line fibre-to-the-home, it is now set to leverage its parent company’s massive mobile data network.

“MTN’s LTE network coverage sits at 95%, after billions of rand was invested in network upgrades in recent years. There is absolutely no reason why those waiting for a fibre connection shouldn’t move to Fixed LTE.”

Collett argues that consumers are far more savvy and well informed of developments in the telecoms space than observers think. They carefully investigate the products and services they choose to spend on, and are looking for the best deals available.

The result is that Supersonic has quietly built up a side business in installing what is called a Mesh Wi-Fi network, consisting of a main Wi-Fi router connected to the standardfibre or LTE or router, and a series of additional access pointscalled plumes, placed in areas of low coverage through ahome.

The plumes – small pods that plug into any power point –connect to one another to expand the network across a wide area. Where traditional WI-FI extenders lose up to half the fibre bandwidth with every extension, the plumes maintain most of the speed regardless of how far the network is extended. All the pods connected to the same router form a single network with the same network name, eliminating the complications Wi-FI extenders usually introduce.

“The traditional Wi-Fi router has replaced the dial up connection, and we’re all happy about this – the infamous dial up tone is ingrained in the brains of anyone over the age of 30,” says Collett. “Wi-Fi revolutionised our way of life as the router gave us access to the internet without directly connecting to a modem. 

“We’ve moved forward, transitioning from ADSL to fibre. While fibre allows for high speed internet access, it is still connected to your Wi-Fi router. Naturally, the further you move away from the hub, the poorer your internet connection will be. Those dead spots around the house can become frustrating when your Wi-Fi signal shows 1 bar and it takes 5 minutes to load a single web page. Mesh Wi-Fi is the solution.”

Collett says he specifically researched a product that looked good, offered app-based management and required no cables. His research led him to Silicon Valley, and the result is the Supersonic Plume Mesh network system.

The drawback is that installation can be complicated for the non-technical consumer. To plug the gap, so to speak, Supersonic sends out technicians who conduct a Wi-Fi sweep of a home and advise how many Plume devices will be needed for 100% coverage. Based on this the technicians make a recommendation for an optimal “smart Wi-Fi”solution. Once installed, though, the network can be monitored and managed from a Supersonic App.

We tried it out and found it was a tale of two experiences. The initial experience was frustrating, as the pods tried to find each other. This is a necessary evil, it seems, as the Plume Mesh network optimises itself over a period of several days. That means the experience at the edge of the network can be very poor at the time of installation. After a few days, however the network was flying.

With a 100Mbps line, the experience next to the main router was around 105 Mbps, both up and down. That in itself was something of a marvel. But the biggest impact was felt at the furthest point from the router: where a Wi-Fi extender had previously delivered speeds of below 10Mbps, download speeds of 80Mbps became not only commonplace, but almost taken for granted.

One of the most useful features of the Plume Mesh is the level of monitoring offered through the Supersonic app. One can observe exactly what devices are connected to which pods – each is given a name, typically of the room, that is visible only through the app.

The biggest surprise of the plume solution is that it has not become a standard solution for Wi-Fi networks everywhere. In an era when we have become deeply dependent on a decent Wi-Fi signal, it has become a necessity rather than a luxury. As a result, home connectivity should be taken far more seriously than merely fobbing consumers off on low-performance extenders. 

MTN seems to have taken this message to heart, rethinking its own approach to home usage.

“Internet access has become the third utility behind electricity and water,” says Collett. “Our goal is to ‘own the home’ but not just by connecting a bunch of devices to a central point. It’s really about how these devices can pioneer habitual change in the home that’s convenient and saves valuable time and money.”

Location data key to transforming SA’s transport system

Published

on

Location technology can transform South Africa’s transport system – but don’t expect to see self-driving cars on our roads any time soon. What’s more relevant is the need for the public and private sectors to work together more closely to unlock the significant social and economic benefits that more efficient transport and mobility systems would bring to the country, including less congestion and fewer road accidents. 

That was the message from Michael Bültmann, Managing Director, in charge of international relations  atHERE Technologies, a global leader in mapping and location platform services, at an event hosted by the international law firm Covington & Burling in Johannesburg last week, to discuss how digitization could support better mobility, safety and integration in South Africa. 

“Society needs to solve some fundamental challenges, and relevant location data can play a key role in creating a better future for mobility in South Africa. If we know where the goods and people are, and how and why they move, we have the basis for a system that matches demand and supply far more closely, and uses our transport infrastructure more efficiently,” saidBültmann.

“But no company, government or individual can do it all themselves. It’s all about collaborating. If we get real-time data use right, it would have a profound effect on the way the entire economy works: less congestion, fewer accidents, more efficient use of vehicles and public transport, less air pollution, greater quality of life, and potential savings of billions of rands in fuel, time and safer roads.”

Speaking at the event, the CSIR’s Dr Mathetha Mokonyama said that despite the billions of rands pumped into the country’s mass public transport network in recent years, 90% of commuter seats available are still provided by either cars or taxis.

“We have the right to dignity. If you want to see indignity, look at people getting up at 2am to get unreliable transport to a job that only pays R3500 a month. In our country, access to transport is critical for people to make a living, and our focus as a country should be to implement an equitable and just transport system that caters to all sectors of society,” he said.

“It was a pleasure to support the event that brought together so many viewpoints on the question of the effective use of data and location intelligence to enhance the mobility of goods, people and services,” said Robert Kayihura, senior advisor in Covington’s Johannesburg office.  “While the harmonization of regulatory regimes around the continent will take time, a key takeaway from our discussions is the critical need to build a shared vision of the future through consistent public-private dialogue and collaboration in order to accelerate and ensure the sustainable and safe digitization of Africa.”

Paul Vorster, the chief executive of the Intelligent Transport Society of SA (ITSSA), said the effective sharing of data between metros, government and the private sector would ‘go a long way’ to improving the efficiency of existing transport infrastructure.

“The starting point is to improve what we already have. Once we know what we have – that is, data – we can start solving real problems, like knowing where the demand and supply are. But to do this, metros will need to learn from each other, and they often face political hurdles in the process,” he said.

Bültmann said increasing levels of urbanisation across the world were creating the need for cities to better predict, manage and plan future urban movement. Combining and analysing data from different, complementary sources could help South African cities to improve urban planning, relieve congestion and curb pollution for better quality of life.

The event was also attended by Presidential Investment Envoy Phumzile Langeni, the National Planning Commission’s Themba Dlamini; SANRAL’s Alan Robinson; and Dr Rüdiger Lotz, the Deputy Head of Mission at the German Embassy. The guests were welcomed by Witney Schneidman, the head of Covington’s Africa practice and former Deputy Assistant Secretary of State for African Affairs (1997-2001) in the U.S. Government.
