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.

Withings raises a massive $30 Million round and welcomes Bpifrance onboard

Withings raises a massive $30 Million round  and welcomes Bpifrance onboard | cross pond high tech | Scoop.it

Health gadget company Withings will announce in a few minutes a new funding round from Bpifrance, Idinvest Partners, 360 Capital Partners and existing investor Ventech. Out of the $30 million, $15 million comes fromBpifrance, the newly created public entity — BPI means Public Investment Bank in French. It is one of its first traditional VC deal.

Withings is perhaps best known for its series of smart scales and body analyzers (along with curious one-off devices like a baby monitor), but the company has recently decided to take a stab at creating yet another sort of fitness gadget: a wearable activity tracker. Calling that particular market crowded is putting it awfully mildly. Devices from the likes of Nike, Jawbone, and Fitbit have put an approachable face on the quantified self movement and have garnered plenty of attention from press and health-conscious consumers.

Philippe J DEWOST's insight:

Massive deal for this side of the pond. Totally impressed and supportive of what Eric Carreel has been achieving in starting 3 companies after his successful Inventel exit !

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.

Samsung Electronics’ 60GHz 802.11 ad Wi-Fi Technology Accelerates Data Transmission by 5x

Samsung Electronics’ 60GHz 802.11 ad Wi-Fi Technology Accelerates Data Transmission by 5x | cross pond high tech | Scoop.it

Samsung Electronics announced the development of its 60GHz Wi-Fi technology that enables data transmission speeds of up to 4.6Gbps, or 575MB per second, a five-fold increase from 866Mbps, or 108MB per second, the maximum speed possible with existing consumer electronics devices.

Unlike the existing 2.4GHz and 5GHz Wi-Fi technologies, Samsung’s 802.11ad standard 60GHz Wi-Fi technology maintains maximum speed by eliminating co-channel interference, regardless of the number of devices using the same network. By doing so, Samsung’s new technology removes the gap between theoretical and actual speeds, and exhibits actual speed that is more than 10 times faster than that of 2.4GHz and 5GHz Wi-Fi technologies.

Philippe J DEWOST's insight:

Is Samsung 802.11ad 60Ghz WiFi "a threat or a promise" ? 15 years after 802.11b, max throughput will have increased more than 400 times ...

Presque 2 ans après son lancement, la Freebox Revolution ne supporte toujours pas le standard WDS

Presque 2 ans après son lancement, la Freebox Revolution ne supporte toujours pas le standard WDS | cross pond high tech | Scoop.it

Ce projet correspond aux anomalies ou aux demandes d'évolutions logicielles pour le Freebox Server.

Philippe J DEWOST's insight:

Le WDS (Wireless Distribution System) est un protocole de la norme WiFi qui permet à des bornes de travailler ensemble et d'étendre un réseau sans fil unique. Par exemple d'ajouter des Airport Express et autres Time Capsules à un réseau Freebox existant plutôt que d'en créer un deuxième ou de bidouiller avec du CPL

 

Or pour une raison incompréhensible, et très peu commentée, Free n'a toujours pas activé cette fonctionnalité dans le firmware de sa Freebox alors qu'apparemment sa carte WiFi Marvell le supporte parfaitement ?
