New Wi-Fi software separates data traffic from control traffic

Published

on

Ruckus Wireless has developed the Virtual SmartZone Data Plane, a virtual data plane for Wi-Fi that separates data traffic from control traffic on large wireless networks.

Carriers and enterprises will now have maximum flexibility in network deployments, installing multiple data flow managers across a distributed network to help optimise cost and performance based on user demands.

The new software – called Virtual SmartZone Data Plane (vSZ-D) – works with Ruckus’ Virtual SmartZone controllers, which provide a software-based system for managing wireless networks. Virtual SmartZone has built strong market momentum in just one year, with more than 700 customers in production networks – managing more than 200,000 access points. Virtual SmartZone is an early highlight in the industry’s network functions virtualization (NFV) movement, which encapsulates key network functions in software that can run on industry-standard hardware.

“Ruckus is once again leading the way in Wi-Fi innovation, making it easier for carriers and enterprises to virtualise and optimise their networks,” said Greg Beach, vice president of product management at Ruckus. “Separating control and data traffic delivers significant flexibility, cost and performance advantages for networks that support thousands of devices and access points.”

Virtual SmartZone Data Plane provides a flexible, cost-effective approach to aggregate and tunnel end-user data for specific application or security policy needs. Tunneling traditionally drives up cost and lowers performance, requiring expensive physical controllers to be replicated at each site – while increasing hardware and labour costs as the network grows. By contrast, vSZ-D distributes the workload across multiple, inexpensive systems – requiring only a single controller instance along with inexpensive vSZ-D deployments at remote sites. Data also moves faster because it can bypass the controller with only incremental impact on each site.

Functionally, the vSZ-D is manageable by the Virtual SmartZone controller, while enabling independent scaling of control and data planes. Multiple vSZ-D instances can be deployed at distributed sites – or an instance can be deployed centrally, helping to afford maximum network design flexibility. The NFV-based design eliminates deployment limitations due to physical computer hardware and geographic location. Virtual SmartZone controllers feature a tremendous level of flexibility: scaling up to 300,000 devices, offering single and multi-tenancy, and enabling “WiFi-as-you-grow” for networks to expand and adapt to the changing needs of their business. The SmartZone software platform supports all of Ruckus’ ZoneFlex indoor and outdoor wireless access points.

Key vSZ-D product features include:

·         Encrypted data tunneling: Provides flexible options for data tunneling from all types of Virtual LANs (VLANs), including guest traffic encryption; point of sale data tunneling for PCI compliance; VoIP traffic tunneling; and seamless roaming across Layer 2 subnets.

·         Dynamic data plane scaling: Provides scale and resiliency for large deployments supporting 1Gbps, 10Gbps or higher throughput – which can be dynamically tuned without needing software updates.

·         Cluster architecture: Provides scale and resiliency for large deployments supporting up to 30,000 access points and 300,000 devices. One Virtual SmartZone controller can manage up to two vSZ-D instances, and four-controller cluster can manage up to 8 vSZ-D instances.

·         Support for multiple hypervisors: Provides initial support for two of the industry’s most widely deployed virtualisation engines – VMware vSphere and KVM (OpenStack).

vSZ-D is immediately available as an extension to Ruckus’ existing Virtual SmartZone controllers – offered in a “high scale” version (vSZ-H) for carriers and large enterprises, and an “essentials” version (vSZ-E) for large and mid-size enterprises. Virtual SmartZone software extends the Smart Wi-Fi technology that has made Ruckus so popular, including proprietary breakthroughs such as BeamFlex+ adaptive antenna technology, ChannelFly predictive channel selection, SmartMesh self-optimised network meshing and Dynamic PSK Wi-Fi security – all of which help Ruckus deliver reliable, secure and scalable high-performance Wi-Fi for enterprise and service providers.

Auto rivals team up for connected car demo

Rivals BMW, Ford and Groupe PSA, maker of Peugeot and Opel cars, have teamed up with the 5G Automotive Association (5GAA), Qualcomm Technologies and Savari for Europe’s first live demonstration of C-V2X direct communication technology operating across vehicles from multiple auto manufacturers.

The live demonstration also featured a live showcase of C-V2X direct communication technology operating between passenger cars, motorcycles, and roadside infrastructure. C-V2X is a global solution for vehicle-to-everything (V2X) communication in support of improved automotive safety, automated driving and traffic efficiency.

The demonstration exhibited the road safety and traffic efficiency benefits of using C-V2X for Vehicle-to-Vehicle (V2V) collision avoidance, as well as Vehicle-to-Infrastructure (V2I) connectivity to traffic signals and Traffic Management Centers (TMC). C-V2X was operated using real-time direct communications over ITS spectrum and demonstrated its ability to work without cellular network coverage, and underscores its commercial readiness for industry deployment as early as 2020. Superior performance and cost-effectiveness compared to other V2X technologies, along with forward-compatibility with 5G, make C-V2X direct communications a preferred solution for C-ITS applications.

Six demonstrations were shown including: Emergency Electronic Brake Light, Intersection Collision Warning, Across Traffic Turn Collision Risk Warning, Slow Vehicle Warning and Stationary Vehicle Warning, Signal Phase and Timing / Signal Violation Warning and Vulnerable Road User (pedestrian) Warning. The vehicles involved included two-wheel e-scooters provided by BMW Group, and automotive passenger vehicles provided by Ford, Groupe PSA, and BMW Group, all of which were equipped with C-V2X direct communication technology using the Qualcomm® 9150 C-V2X chipset solution.  V2X software stack and application software, along with roadside infrastructure, were provided by industry leader, Savari.

C-V2X is globally supported by a broad automotive ecosystem, which includes the fast growing 5GAA organization.  The 5GAA involves over 85 global members comprised of many leading automakers, Tier-1 suppliers, software developers, mobile operators, semiconductor companies, test equipment vendors, telecom suppliers, traffic signal suppliers and road operators.  

Cellular modems will be key to the C-V2X deployment in vehicles to support telematics, eCall, connected infotainment and delivering useful driving/traffic/parking information. As C-V2X direct communication functionality is integrated into the cellular modem, C-V2X solutions are expected to be more cost-efficient and economical over competing technologies, and benefit from accelerated attach rates.  C-V2X direct communication field validations are currently underway in Germany, France, Korea, China, Japan and the U.S.

C-V2X currently stands as the only V2X technology based on globally recognized 3rd Generation Partnership Project (3GPP) specifications, with ongoing evolution designed to offer forward compatibility with 5G.  C-V2X also leverages and reuses the upper layer protocols defined by the automotive industry, including the European Telecommunications Standards Institute (ETSI) organization. C-V2X includes two complementary transmission modes: 

  • Direct communication as shown in this demonstration for V2V and V2I use cases
  • V2N network communication, which leverages mobile operators for connectivity and delivers cloud-based services, including automated crash notification (ACN, as mandated by eCall), hazard warnings, weather conditions, green light optimal speed advisory (GLOSA), parking spot location, and remote tele-operation to support automated driving, to name a few.

“This demonstration builds on the successful C-V2X showcase we organised with our members Audi, Ford and Qualcomm in Washington DC in April, said Christoph Voigt, Chairman of 5GAA.

“We are excited to witness the growing momentum behind this life-saving technology and to see our members working together to deploy C-V2X, and to make it hit the road as soon as possible.”  

“The BMW Group introduced the first C-ITS use cases already in 2013 with the market introduction of the BMW i3. Today most of envisaged C-ITS use-cases are already institutionalized. With the implementation of C-V2X, the BMW Group accomplishes the last set of the puzzle with a practical path to C-ITS showing quick benefits,” said Christoph Grote, Senior Vice President Electronics, BMW Group. 

“With its ability to safely and securely connect vehicles, along with its evolution into 5G, C-V2X is integral to Ford’s vision for future transportation in which all cars and infrastructure talk to each other,” said Thomas Lukaszewicz, Manager Automated Driving, Ford of Europe. “We are very encouraged by preliminary test results in Europe and elsewhere which support our belief that C-V2X direct communications has superior V2X communication capabilities.”

“We’re moving forward with seamless communication between cars and their environment for enhancing road safety, as well as our customers’ safety,” said Carla Gohin, Group PSA’s Vice President for Research and Advanced Engineering. “Following the first European C-V2X direct communications demonstration we hosted with Qualcomm Technologies last March, we’re pleased to work with leading automotive and technology companies today to highlight that C-V2X interoperability is a reality.” 

“This demonstration of interoperability between multiple automakers is not only another milestone achieved towards C-V2X deployment, but also further validates the commercial viability and global compatibility of C-V2X direct communications for connected vehicles,” said Enrico Salvatori, senior vice president & president, Qualcomm Europe and MEA. “We look forward in continuing to work alongside leaders in the automotive industry, like the 5GAA, BMW Group, Ford, Groupe PSA and Savari, to help advance the automotive industry’s shift towards a safer, connected and more autonomous future.” 

“As one of the V2X pioneers, our company is extremely pleased to continue to help enable the next step in the V2X revolution that we helped start back in 2008,” said Ravi Puvvala, CEO of Savari. “For the last year and a half, the Savari team has worked diligently alongside the dedicated C-V2X engineers in the 5GAA partnership. The resulting string of increasingly impressive demonstrations is continuing to convince the world that C-V2X will soon be deployed around the world.”

Win a Poster Heater with Gadget and Takealot.com

This winter Gadget and Takealot.com are giving away three Poster Heaters, which look like posters but become heaters when you plug them in.

Published

on

Three Gadget readers will each win a unit, valued at R550 each. To enter, follow @GadgetZA and @Takealot on Twitter and tell us on the @GadgetZA account how many Watts the heater consumes.

What’s the big deal about these heaters? Many of us are struggling to keep the balance between soaring electricity costs and the need to keep warm this winter.

However, the recently launched Poster Heater by EasyHeat and distributed in South Africa by Takealot.com is not only one of the most cost effective electric heaters currently on the market, it is also easy to setup and use.

As the name indicates, it is a poster similar to one you would hang on a wall. But, plug it in and it turns into a 300 Watt heater. The Poster Heater isn’t designed to heat hallways or large rooms, but rather smaller ones like a bedroom or a baby’s nursery or a dressing room.

It uses radiant heating, which means that it heats up in a couple of minutes and the heat is directed at the objects or people around it, quickly taking the chill out of the air and providing a comfortable ambient temperature.

The other advantage of radiant heating is that it doesn’t dry out the air like infrared or gas heaters. Users also don’t have to worry about their children or pets getting too close to it because, even though it gets hot, it can be touched.

To enter the competition follow the steps below:

Competition entry details:

1. Follow @GadgetZA and @Takealot on Twitter. (We will ONLY be accepting entires via Twitter, so please don’t enter through the comments section of this article.)
