Bluetooth Reaches Version 4.2

Bluetooth Reaches Version 4.2

The Bluetooth Special Interest Group (SIG) announces Bluetooth core specification version 4.2-- an update featuring improvements on security and speed, as well as an IP connectivity-enabling profile.

“Bluetooth 4.2 is all about continuing to make Bluetooth Smart the best solution to connect all the technology in your life-- from personal sensors to your connected home," the SIG says. "In addition to the improvements to the specification itself, a new profile known as IPSP enables IPv6 for Bluetooth, opening entirely new doors for device connectivity.”

On the security front Bluetooth 4.2 should make it harder for eavesdroppers (such as Apple's iBeacons) to track devices without direct user permission. It also promises to transfer data up to 2.5 times faster than previous versions, with reductions in both transmission errors and power consumption.

Old TV Frequencies for "Super Wifi"?

Old TV Frequencies for

Researchers at the Karlsruhe Institute of Technology (KIT) suggest governments should not auction off old TV frequencies to the highest bidders-- instead they be used to create a free "super wifi" network.

Old TV frequencies allow the transmission of wifi over lower frequencies , resulting in coverage as wide as several kilometres in radius. Such a network could replace pricey mobile services of the 4G variety, leading to far wider mobile internet use.

Current wifi technology operates at high frequencies of 2GHz and above.

The KIT researchers say they also have a technique for the prevention network congestion via the reserving of a 90MHz interval in the UHF bands. Another argument in favour is that in any case the general public should be given preference to the use of electronics communications.

ZigBee Reaches Version 3.0

ZigBee Reaches Version 3.0

The ZigBee Alliance unifies multiple ZigBee wireless networking technologies into a single standard-- ZigBee 3.0, a means enabling communications between multiple devices in both residential and enterprise applications.

ZigBee 3.0 is IEEE 802.15.4-based, operates at 2.4GHz and uses ZigBee PRO, the group's standard for network formation and the devices attached to them. However it lacks 2 ZigBee specs, namely Smart Energy 2.0 (an IP-based profile) and RF4CE (a ZigBee version geared at remote controls).

“Underneath the covers we are accommodating these multiple applications in a single standard, so ZigBee thermostats, for example, can be used in either home or office buildings,” the Alliance says.

Quantenna, SoftAtHome Team Up in Wireless

Networking vendor Quantenna and smart home platform developer SoftAtHome announce a team-up in next generation wireless home networks combining the SoftAtHome software with Quantenna wifi technology.

The first result of the partnership is the SOP7 embedded software platform. Powered by Quantera's QSR1000 4x4 800.11ac wifi chipset, the SOP7 claims to provide OEMs with greater bandwidth for TV and network operator solutions ranging from STBs to dongles, NAS and home gateways.

The partnership also covers multiple wifi and home networking areas, namely gateways-service connectivity, band steering, P1905 standard bandwidth management and cloud-based wifi network management.

Samsung Claims Faster Wifi

Samsung announces the development of 60GHz wifi technology-- enabling wireless data transmission speeds of up to 4.6Gbps (or 575MB per second), a five-fold increase over the current 866Mbps maximum.

The company says it allows the transfer of a 1GB movie in less than 3 seconds, as well as real-time uncompressed HD video streaming from mobile devices to TVs.

According to Samsung the 802.11ad 60GHz wifi technology eliminates co-channel interference regardless the number of devices using the same network in order to maintain maximum speeds and remove the gap between theoretical and actual speeds. How so? Via the use of "micro beam-forming control technology" optimizing the communications module in less than 1/3000 seconds.
