An Cloud-Based Imp in the Internet of Things

  • PDF

Electric Imp has a simple proposal to bring about the so-called "internet of things"-- connecting almost any device to the internet with the addition of a simple card in a slot.

Created by ex-Apple and Google engineers, the Electric Imp card looks very similar to standard SD cards. It carries a wifi 802.11b/g/n radio, a Cortex M3-based processor and software-controllable I/O pins.

Once the user installs the Imp card into a device (be it a coffee machine, a washing machine or a lighting system) using an Electric Imp circuit board-- the company is also in talks with OEMs to get slots pre-installed into products--  the card connects to the internet, allowing users to control the device remotely via Electric Imp's online cloud and simple web-based software.

The "internet of things," in other words.

Currently the Electric Imp card exists as a developer preview, which company will start shipping from June 2012 for $25. It is also in talks with vendors, who will release compatible devices later this year.

CEDIA on Mobile-Friendly Networks

  • PDF

CEDIA releases the 2nd white paper on the integration of mobile devices in residential systems-- Ten Steps to Creating a Robust Wireless Environment for Mobile Device Integration.

CEDIAAs customers depend more on IP networks and mobile device numbers grow, modern homes need increasing amounts of wireless bandwidth in order to keep all devices working and communicating at all times.

Thus the white paper provides installers with a 10-step roadmap to creating a profitable and repeatable wifi solution.

The paper combines with the advanced IP and networking courses the association offers at CEDIA EXPO, and is available from the CEDIA marketplace.

Wifi Hits "T-Ray" Milestone

  • PDF

Japanese researchers at the Tokyo Institute of Technology smash the record for wireless data transmission over the "T-ray" band, achieving 3Gbps transfer over a 542GHz wireless connection.

TRay WifiThe data rate achieved is double the previous record from chip maker Rohm of 1.5Gbps transfers using a 300GHz connection. Such connections falls into the 300GHz-3THz band, known as the terahertz spectrum or simply "T-rays."

300GHz is 60x higher than the highest current wifi standard.

Tetraherz wifi has range limitations (around 10m) but supports data rates of up to 100Gb/s, nearly x15 higher than the next generation of 802.11ac wifi.

The Japanese researchers achieve such wifi speeds using a resonant tunneling diode (RTD), a 1mm-square device that "resonates" and transmits electro-magnetic signals at very high frequencies. Previous T-ray experiments required bulky, costly and power-hungry equipment with science fiction-esque names like "quantum cascade lasers."

Project leader Dr. Safumi Suzuki is confident tetraherz communications are ripe for consumerisation-- he believes "everybody will use products related to THz technology within the next decade."

Wifi Gets Fourth Revision

  • PDF

IEEE publishes the latest revision of the 802.11 wifi standard, IEEE 802.11-2012-- with revisions promising improved connections, greater security and smoother handoffs between wifi and mobile networks.

IEEE wifiThe 4th revision since 1997, 802.11-2012 consolidates the 10 amendments to the base standards approved in the 2007 revision. These include 802.11n (defines MAC and PHY modifications to enable throughputs of up to 600MB/s), direct-link setup, "fast roam," radio resource measurement, operation in the 3650-3700MHz band, vehicular environments, mesh networking, security, broadcast/multicast and unicast data delivery, interworking with external networks and network management.


EC Consultation on Internet of Things

  • PDF

The European Commission (EC) opens a consultation process on regulations regarding wireless connected devices and the internet of things, as part the Digital Agenda for Europe.

internet of thingsApparently the EC wants to start working on the framework required to "unlock the economic and societal benefits of the internet of things," together with control on the gathering, processing and storage of data by devices.

According the commission the average citizen owns at least 2 internet-connected devices-- a figure to reach 7 by 2015. The commission also says the global number of wirelessly connected devices will double to 50 billion by 2020.

The consultation seeks opinions on privacy, safety and security, security of critical IoT supported infrastructure, ethics, interoperability, governance and standards. One can participate by clicking the link below.
