Wireless sensors are coming

The Dash7 Alliance promotes the ISO 18000-7 standard for wireless sensor networking.
On 2013-09-25 it announced the public release of the first version of the DASH7 Alliance Protocol.
Low implementation costs will be important in its competition with Zigbee.
Operating at a lower frequency DASH7 has an inherent range advantage but lower throughput.
Dash7 also specifies lower power usage than Zigbee but lesser security features.
Although Zigbee and Dash7 have overlapping applications their different characteristics should allow both to find a niche.

Smartphones Wi-Fi and Wi-Fi roaming

On 2013-09-24 there were 2449 smartphones listed by the Wi-Fi Alliance as Wi-Fi Certified

72 were listed as 5G Wi-Fi enabled i.e. 802.11ac

63 were listed as Passpoint Certified i.e. 802.11u

5G Wi-Fi is important primarily because its speed and range improvements in the less congested 5 GHz frequencies lead to a better experience. More 5G Wi-Fi networks need to be deployed.

Passpoint (Hotspot 2.0) is important because it enables ‘Wi-Fi roaming’. This automates login to diverse Wi-Fi networks. The effect is generally a faster connection than a mobile carrier can provide because of the rapid growth in mobile data usage. As a result it is sometimes called ‘mobile carrier offloading’ or ‘Wi-Fi offloading’.

The Wireless Broadband Alliance are promoting Wi-Fi roaming in their Next Generation Hotspot (NGH) project.

Wireless Power

Many companies are developing wireless power systems, but one seems to have an advantage.

Ossia Inc. is developing technology they claim can charge devices at up to 30 feet, others claim only millimetres or centimetres.

They say they are in talks to bring their Cota system to market and think it should be in consumer products by 2015.

At Wireless Head our business is the application of wireless technology to business; so if Ossia Inc. can free us from that last wire it is great news to us.

Take a look at this presentation by the founder and CEO of Ossia for TechCrunch.
