“100km network won’t interfere with TV”
…which is of course the most important thing in life!
– IEEE publishes long range wireless standards (Tech Eye):
100km network won’t interfere with TV
New standards for long range wireless networks have been published today by the IEEE.
The 802.22 standard for Wireless Regional Area Networks (WRANs) means that broadband access can be provided over long distances, up to 100 kilometres.
This will mean that rural areas could more easily benefit from broadband access, with developing countries targeted by the IEEE.
Of course, as Ofcom has been reminded of lately, even in little old England there are many areas which cannot be reached.
The engineers at the IEEE have very cleverly managed to use the VHF and UHF bandwidths usually used for TV, accessing the “white-spaces between TV channels” at the 54 MHz to 862 MHz spectru,.
This is possible by using cognitive radio capabilities. These include dynamic spectrum access, incumbent database access, accurate geolocation techniques, spectrum sensing, regulatory domain dependent policies, spectrum etiquette, and “coexistence for optimal use of the available spectrum”.
Essentially this means that it will be possible to send wireless broadband access without interfering with TV signals, achieving delivery of up to 22 Mbps per channel.
According to Andrew Ferguson at Thinkbroadband.com such wireless networks could potentially be for connecting areas that are without access.
“Wireless would certainly be easier than fibre connections to areas where ground would actually be dug up to provide a connection,” he told TechEye.
“But whether the speeds would be high enough is unclear, with many looking above the 25 Mbps mark.”
Virgin Media told us that while it was looking to support access in rural communities, it places more emphasis on the higher speeds of cable broadband, with the IEE spec not necessarilty high enough for a full range of services.
According to Alex Buttle, marketing director at uSwtich telecoms, the publishing of the standards is a positive step for net equality.
“It is a hugely positive new technology, and it is good for equality of connectivity across the world,” he told us.
“The standard across the world has been quite poor so far so this would certainly be raising the bar of what is available, so is definitely a positive step.”
“Wireless networks are good way to bridge the gap where it is difficult to cable broadband.”
“So in terms of bringing rural communities up to speed it would definitely be worth Ofcom’s investment to help roll out the technology.”
The official publication of the first intermediate results of the International Interphone Study from the International Research Centre on Cancer (CIRC) dependent on WHO confirms the increased tumors and cancer cases due to the use of mobile phone

(Natural News) A new review of more than 100 studies on the safety of mobile phones has concluded that cellular devices are poised to cause an epidemic of brain tumors that will kill more people than smoking or asbestos.
The review was conducted by neurosurgeon Vini Khurana, who has received more than 14 awards in the past 16 years, who made headlines worldwide with his warnings. He called upon the industry to immediately work to reduce people’s exposure to the radiation from mobile phones.
The studies and survey conducted by Australian Health Research Institute indicates that due to billions of times more in volume electromagnetic radiation emitted by billions of mobile phones, internet, intranet and wireless communication data transmission will make almost one-third of world population (about two billions) patient of ear, eye and brain cancer beside other major body disorders like heart ailments, impotency, migraine, epilepsy.
Dr. George Carlo was the leading scientist of the biggest study ever ($28-million)conducted on Cell Phones.
Dr. Carlo was hired as an independent scientist by the industry to prove that cellphones are safe. Yet Dr. George Carlo hissed all red flags possible (incl. cancer)!

They found that mothers who did use the handsets were 54 per cent more likely to have children with behavioural problems and that the likelihood increased with the amount of potential exposure to the radiation. And when the children also later used the phones they were, overall, 80 per cent more likely to suffer from difficulties with behaviour. They were 25 per cent more at risk from emotional problems, 34 per cent more likely to suffer from difficulties relating to their peers, 35 per cent more likely to be hyperactive, and 49 per cent more prone to problems with conduct.
