In the roughly two years since Aruba Networks was acquired by HPE, it’s become the larger company’s de facto wireless arm, more or less taking over HPE’s existing networking division and changing almost not at all after the merger.
Network World sat down with Senior Vice President and General Manager Keerti Melkote and CTO Partha Narasimhan at Aruba’s annual Atmosphere conference in Nashville last week to talk about future wireless technology, security, and more.

Staring at a Chapter 11 bankruptcy, Avaya told the court last week it wants out of the$350,000 annual payment for its San Francisco 49ers stadium suite and that the team’s recent miserable performance has made the suite harder to sell off.
According to a Reuters report, the cost of the license for the suite, $350,000 due this month, is a burden on Avaya's estate and the company is seeking court permission to reject the agreement which was signed for 10 years.To read this article in full or to leave a comment, please click here

Cisco today issued a security warning about a potential vulnerability in its NetFlow traffic monitoring device that could cause the system to lock-up.
+More on Network World: Cisco tries to squash Smart Install security abuse+
Specifically, Cisco wrote: “A vulnerability in the Stream Control Transmission Protocol (SCTP) decoder of the Cisco NetFlow Generation Appliance (NGA) could allow an unauthenticated, remote attacker to cause the device to hang or unexpectedly reload, causing a denial of service (DoS) condition. The vulnerability is due to incomplete validation of SCTP packets being monitored on the NGA data ports. An attacker could exploit this vulnerability by sending malformed SCTP packets on a network that is monitored by an NGA data port. SCTP packets addressed to the IP address of the NGA itself will not trigger this vulnerability. An exploit could allow the attacker to cause the appliance to become unresponsive or reload, causing a DoS condition. User interaction could be needed to recover the device using the reboot command from the CLI.”To read this article in full or to leave a comment, please click here
The U.S. Federal Communications Commission's net neutrality rules, passed two years, ago were a "mistake" that caused uncertainty for the broadband industry, the agency's new chairman said.The net neutrality rules, along with the FCC's decision to reclassify broadband as a regulated common carrier, "deviated" from the U.S. government's longstanding light-touch regulatory approach toward the internet, FCC Chairman Ajit Pai said Tuesday at the Mobile World Congress in Barcelona.RELATED: The hidden cause of slow Internet and how to fix it
Two years after the agency passed its net neutrality rules "it has become evident that the FCC made a mistake," said Pai, a Republican. "Our new approach injected tremendous uncertainty into the broadband market. And uncertainty is the enemy of growth."To read this article in full or to leave a comment, please click here
The digital world is all about IP (internet protocol) addresses. Every device needs an IP in order to communicate on the internet or within a private network. Given there’s not enough public IP addresses out there for every internet-connected device (at least with IPv4), this little thing called NAT becomes extremely important. It stands for network address translation (NAT) and is a function provided by routers to enable multiple devices to access the internet via a single public IP address.Behind each public IP, there can be hundreds of devices with their own private IP addresses, thanks to NAT. And almost all equipment that provides the NAT function includes a firewall to protect the private IPs and devices from public IPs and devices on the internet. Other network services are also typically offered, like DHCP (dynamic host control protocol) to give out the private IP addresses to devices that connect to the local network.To read this article in full or to leave a comment, please click here
Think about how annoyed you get when you lose your cell signal, and you can see why Intel is pushing for advances in the next generation of networking, also known as 5G. Sure, the company stands to profit from making chips and networking equipment to support faster broadband. Consumers, too, stand to benefit from a future where more things in their lives are connected. To get there, though, we’re all going to need more bandwidth.At Mobile World Congress, Intel demonstrated several initiatives for developing 5G capabilities. Watching virtual reality’s often stuttery video can make people queasy, but Intel demonstrated how 5G could let you stream 8K VR content. The company also showed how self-driving cars will need a speedy 5G network to communicate with other cars and infrastructure so they can move safely.To read this article in full or to leave a comment, please click here
Fast-growing Indian mobile operator Reliance Jio may offer a glimpse of where all mobile networks are going eventually, to packet-based Internet Protocol infrastructure.At Mobile World Congress, the world’s largest gathering of the mobile industry, Reliance Jio stands out by having none of the specialized 2G and 3G infrastructure that long distinguished cellular carriers.Almost all mobile operators still have circuit-switched network gear in addition to IP systems. It came along with the 2G and 3G networks the carriers used before adopting LTE. Most are likely to keep older networks running for years, though some are moving faster than others to clear the decks.To read this article in full or to leave a comment, please click here

For the past few weeks attackers have been probing networks for switches that can potentially be hijacked using the Cisco Smart Install (SMI) protocol. Researchers from Cisco's Talos team have now released a tool that allows network owners to discover devices that might be vulnerable to such attacks.The Cisco SMI protocol is used for so-called zero-touch deployment of new devices, primarily access layer switches running Cisco IOS or IOS XE software. The protocol allows newly installed switches to automatically download their configuration via SMI from an existing switch or router configured as an integrated branch director (IBD).The director can copy the client's startup-config file or replace it with a custom one, can load a particular IOS image on the client and can execute high-privilege configuration mode commands on it. Because the SMI protocol does not support any authorization or authentication mechanism by default, attackers can potentially hijack SMI-enabled devices.To read this article in full or to leave a comment, please click here
Seven billion connected devices and counting—and we are only at the threshold of the massive, new class of connected devices known as the Internet of Things (IoT).Devices, such as sensors, remote robots and everyday objects, are rapidly becoming connected to expand the universe of IoT and to provide valuable data. In a network-centric world, the more devices that are connected in aggregate, the more value is created for the whole. And this value scales exponentially. It’s what’s called a network effect, and it can bring boundless possibilities for value and wealth creation in the next five years.To read this article in full or to leave a comment, please click here
Mobile World Congress takes place this week, so it’s time again for carrier and vendors to serve up bold claims about what 5G cellular will do for users -- this time, with a dash of realism.“5G is not ready yet,” T-Mobile USA’s CTO Neville Ray said Monday morning. “It’s maturing quickly, but it’s not real today, and I can’t go and deploy a 5G radio to serve my customers with and give them a handset.”Like most other carriers, T-Mobile is testing pre-standard 5G technology, and Ray is enthusiastic about the next generation in the long term. But he reminded the audience that some parts of 5G, like using ultra-high frequencies to reach mobile devices, still face big technical challenges and 4G will still be around for years after the first big 5G rollouts happen around 2020.To read this article in full or to leave a comment, please click here
At Mobile World Congress this morning, Deutsche Telecom, SK Telecom and Ericsson showed a telepresence-controlled robot prototype to demonstrate the capabilities of 5G wireless networks, software-defined networks (SDN) and Network Functions Virtualization (NFV).The point made is 5G’s ultra-low latency delivered end to end with SDN and NFV will enable new real-time use cases for industrial services, autonomous cars and the Internet of Things (IoT). Within a 5G radio access network (RAN), 5G can deliver sub-1ms latency. But a loaded RAN or traversing a network between RANs can add tens of milliseconds—too much for control applications that require synchronization over distances.To read this article in full or to leave a comment, please click here
The purpose of indoor Wi-Fi is no longer simply about providing internet connectivity. Indoor positioning services that enable asset tracking and visitor navigation functions are adding to the traditional access point feature set of spotty internet access.GPS positioning doesn’t work as well indoors as out. And Wi-Fi equipment vendors are keen to point out that networks created with their equipment are better suited to indoor locationing—better than cellular, too, with its usually outdoor masts.This has led to the newest Wi-Fi system: meter-level positioning.9 tips for speeding up your business Wi-Fi
The latest nod comes from the Wi-Fi Alliance, the certifier and association of Wi-Fi technology companies. It just launched a certified program for “meter-level accuracy for indoor device location data” using its technology.To read this article in full or to leave a comment, please click here
SK Telecom and Nokia have developed a prototype quantum cryptography system that combines the South Korean company's quantum key server with an encryption device from Nokia.The system, shown Monday at Mobile World Congress in Barcelona, was put together to demonstrate interoperability between the two vendors and comes as SK Telecom kicks off a push to get telecom carriers and equipment vendors working together on next-generation quantum-secured networks.Quantum cryptography involves the transmission of encryption keys across fiber optic networks. It relies on the principles of quantum mechanics to detect if an eavesdropper has viewed a key en route.To read this article in full or to leave a comment, please click here
If your travel plans over the next week or so include Mobile World Congress (MWC) in Barcelona, then one thing I am sure you will know is that 5G will be a hot topic. The 5G requirements are now well-aired and the triumvirate of use cases (enhanced mobile broadband (emBB), ultra-low latency reliable communications (URLLC) and massive machine type communications (mMTC) are commonly understood.+ Also on Network World: 4 things we expect from Mobile World Congress 2017 +

While next-generation 5G cellular will bring faster downloads for consumers, the new networking technology is poised to bring big benefits to business users enabling new uses for cellular networks.At this week's Mobile World Congress in Barcelona, Japan's NTT DoCoMo is demonstrating one such use: remote control of robots via a wireless virtual reality system.In one corner of the company's booth was a simulated factory floor with three robots. The area was surrounded by four depth-sensing 3D cameras that together provide enough video for an immersive, all-around virtual reality image.That 3D video, totaling roughly 700Mbps of data, was sent across a 5G radio link to a receiver where it was processed and fed to a VR headset. The radio link was running across a few meters on the crowded expo floor but it was hitting a top speed of around 15Gbps -- that's many times faster than is possible with the fastest of today's 4G networks.To read this article in full or to leave a comment, please click here
While next-generation 5G cellular will bring faster downloads for consumers, the new networking technology is poised to bring big benefits to business users enabling new users for cellular networks.
Enterprises and cloud companies will start trying their hands at cellular this year, Nokia President and CEO Rajeev Suri predicts.“Enhanced reality” and events such as concerts may be where cloud giants first get into mobile services, Suri said at a Nokia event in Barcelona on the eve of Mobile World Congress.“The first webscale players will enter the wireless access domain with mainstream technologies,” Suri said. Webscale usually refers to operators of big clouds, like Google, Facebook, and Alibaba. Suri didn’t name any names.For enterprises, an emerging technique called network slicing will allow them to virtually run their own private services on mobile operator networks. Meanwhile, systems that bring LTE to unlicensed or shared frequencies, like LAA (Licensed Assisted Access), will also help open doors to private cellular networks. Nokia is already working with some energy utilities on these kinds of deployments, and at MWC it will join Qualcomm in demonstrating a private LTE network, Suri said.To read this article in full or to leave a comment, please click here
Mobile World Congress, the Davos of wireless technology, is happening next week in Barcelona, and it’s going to be a particularly important year, as the mobile landscape readies itself for a couple of fairly major shifts.Here’s our quick look ahead to next week in sunny Spain and the four main points we expect from the MWC show.5G, or at least previews of it
There’s been a big school of 5G press releases floating into our inboxes here in tech media just ahead of MWC (i.e., “Verizon plans 5G wireless trial service in 11 cities this year”), and it’s no real surprise – next-generation mobile networks are going to do a lot more than just boost speeds. They’ll also connect large numbers of devices – not just phones and tablets and laptops – to each other.To read this article in full or to leave a comment, please click here
