Full speed ahead for 802.11ac Gigabit Wi-Fi

Full speed ahead for 802.11ac Gigabit Wi-Fi | cross pond high tech | Scoop.it
Last December customers were peppering wireless LAN vendors with questions about whether to upgrade to the pre-standard-but-certified 802.11ac products flooding the market or hold off until 2015, when more powerful “Wave 2” Gigabit Wifi gear was expected to become prevalent. A year later, even though Wave 2 products have begun trickling into the market, many IT shops seem less preoccupied with Wave 2 and more focused on installing the Wave 1 11ac routers, access points and other products at hand
Philippe J DEWOST's insight:

Time to check for your 802.11ac compatibility. WiFi isn’t about the coverage anymore, it’s about capacity.

Telecom Council of Silicon Valley nominates SIGFOX as one of the world's 5 most innovative startups | cross pond high tech | Scoop.it

The Telecom Council of Silicon Valley connects companies and individuals involved in the Communications Technology industry with one another for business development, collaboration, and education.

Every year, the council organizes the TC3, Telecom Council Carrier Connections. This 2-day executive summit highlights the relationship between the companies building communication networks, with the companies and new ideas that are fueling its growth.

This event is also the opportunity for the Telecom Council to highlight innovative telecom companies with the SPIFFY Awards. And this year, SIGFOX has been invited as a nominee in the category Edison Award for Most Innnovative Start-Up.

Facebook Rattles Networking World With 'Open Source' Gear

Facebook Rattles Networking World With 'Open Source' Gear | cross pond high tech | Scoop.it

Two years ago, Mark Zuckerberg and company turned the hardware world on its head when they launched the Open Compute Project, an effort to improve every aspect of the modern data center and share the results with the world at large. They began by “open sourcing” fresh designs for computer servers and power systems and cooling equipment. Then they did the same with hardware that stores massive amounts of digital data. Then they remade the racks that hold all these machines. And now it’s time for the networking gear.


The idea is to design a networking switch that anyone can load with their own operating system — just as you can load your own OS on a computer server. Typically, networking switches are sold by hardware giants such as Cisco and HP and Dell, and they ship with software specific to the company that designed them. But Facebook aims to separate the hardware from the software.

After opensourcing data center gear end equipment, Facebook extends the approach to network : towards open SDN?

SSH Backdoors Found in Barracuda Networks Gear

SSH Backdoors Found in Barracuda Networks Gear | cross pond high tech | Scoop.it

A variety of the latest firewall, spam filter and VPN appliances sold by Campbell, Calif. based Barracuda Networks Inc. contain undocumented backdoor accounts, the company disclosed today. Worse still, while the backdoor accounts are apparently set up so that they would only be accessible from Internet addresses assigned to Barracuda, they are in fact accessible to potentially hundreds of other companies and network owners.


Barracuda’s hardware devices are broadly deployed in corporate environments, including the Barracuda Web Filter, Message Archiver, Web Application Firewall, Link Balancer, and SSL VPN. Stefan Viehböck, a security researcher at Vienna, Austria-based SEC Consult Vulnerability Lab., discoveredin November 2012 that these devices all included undocumented operating system accounts that could be used to access the appliances remotely over the Internet via secure shell (SSH).

 

Viehböck found that the username “product” could be used to login and gain access to the device’s MySQL database (root@localhost) with no password, which he said would allow an attacker to add new users with administrative privileges to the appliances. SEC Consult found a password file containing a number of other accounts and hashed passwords, some of which were uncomplicated and could be cracked with little effort.

T-Mobile's USA HSPA+ 42 smartphone users guzzle 1.3 GB per month - FierceWireless

T-Mobile's USA HSPA+ 42 smartphone users guzzle 1.3 GB per month - FierceWireless | cross pond high tech | Scoop.it
T-Mobile USA subscribers with smartphones capable of accessing the carrier's HSPA+ 42 Mbps network consume an average of 1.3 GB per month. The figure is almost double the 760 MB per month that T-Mobile said its overall smartphone user base consumes, and it highlights the fact that users generally consume more mobile data if they have access to a faster network.

Click here for Ray's full presentation. (PDF)

According to Chetan Sharma Consulting, roughly 30 percent of all U.S. smartphone users download more than 1 GB of data per month.

T-Mobile CTO Neville Ray disclosed the carrier's figures during a presentation at the NGMN conference in San Francisco. Ray also said that video accounts for almost 50 percent of T-Mobile's overall HSPA network traffic.

Currently, T-Mobile offers an HSPA+42 network covering 184 million POPs in 185 markets, and its HSPA+21 network covers around 220 million POPs. The carrier advertises the network as "America's largest" that provides "4G" speeds. Indeed, independent tests have shown that T-Mobile's HSPA+ 42 network offers download speeds of around 8 Mbps, similar to what Verizon Wireless (NYSE:VZ) provides via its LTE network.

Laurent Bloch : « La France est en train de rater la troisième révolution industrielle »

Laurent Bloch : « La France est en train de rater la troisième révolution industrielle » | cross pond high tech | Scoop.it

.../... le commerce du contenu et des données n’est que la partie visible de l’iceberg, En dessous, il y a les matériels et les réseaux. On parle souvent d’Internet comme si c’était un espace totalement immatériel. C’est faux. L’entreprise Google est un géant industriel. Elle possède des millions de serveurs dans le monde entier, regroupés dans des data centers, qui sont des usines informatiques. Pour assurer son approvisionnement énergétique, Google rachète des centrales hydro-électriques.

Même chose pour les réseaux : Google et Facebook possèdent leurs propres câbles transatlantiques et leurs nœuds de communication. Leurs activités commerciales dépendent avant tout de leurs infrastructures matérielles.

'Biggest ever attack' slows internet

'Biggest ever attack' slows internet | cross pond high tech | Scoop.it

The internet around the world has been slowed down in what security experts are describing as the biggest cyber-attack of its kind in history.

A row between a spam-fighting group and hosting firm has sparked retaliation attacks affecting the wider internet.

It is having an impact on popular services like Netflix - and experts worry it could escalate to affect banking and email systems.

Five national cyber-police-forces are investigating the attacks.

Why Cisco Just Spent $1.2 Billion on Meraki

Why Cisco Just Spent $1.2 Billion on Meraki | cross pond high tech | Scoop.it
Cisco bought a wifi startup called Meraki for $1.2 billion.

Here's the blog post everyone is passing around to explain how that happened.

It's from Doug Leone, who got his VC firm, Sequoia Capital, to invest in Meraki:

Quick: when was the last time you plugged in an Ethernet cable? If you have trouble answering that question, you’re one of the reasons why Cisco has agreed to acquire Meraki.

Smartphones Just Don’t Shut Up: some apps ping the network as often as 2400 times an hour

Smartphones Just Don’t Shut Up: some apps ping the network as often as 2400 times an hour | cross pond high tech | Scoop.it
It's not just that modern smartphones are gobbling up tons of data. Another part of their challenge to wireless networks is that they are constantly pinging the network.

A less talked-about issue is the fact that many smartphone apps are constantly pinging the network, like a kid asking his or her parents every few seconds, “Are we there yet?”

Only smartphone apps are even more annoying. Some ping the network as often as 2,400 times an hour. The result is network congestion and signal loss, as well as a far more rapid drain on battery life.

“Wireless signaling is a tricky topic because oftentimes it’s hidden, happening in the background without any user knowledge. But it’s growing bigger by the minute, as more users download more connected applications” said Isabelle Dumont, head of marketing at Seven Networks, which pitches a solution to help reduce the issue.

If current trends continue, the constant pinging of the network could eventually amount to 25 trillion signaling events per hour, Seven says.
