Provides Eduroam which allows students and staff to gain wireless access to a network of an institution (connected to SURFnet) where they are a guest by using their own institutional account.
eduroam-US -- US Eduroam Access
Networks from R&E institutions negotiate once during the federation process and for all members of participating institutions. The eduroam network addresses CALEA requirements for visitors from other schools. A non-AARNet branded version of what is eduroam that is available for participating National Education and Research Networks and academic institutions that are part of the eduroam community to use or link to.
As a user: If you can join eduroam at your home institution then you can join the eduroam wireless network everywhere you see it, in exactly the same way. If you have difficulty joining, many schools have support sites for users; check there for more information on getting online with eduroam.

 

BROADBAND

WIFI SPECTRUM

 

 

The National Telecommunications and Information Administration announced on March 27, 2012 that is taking steps to clear the 1755-1850 Mhz band for commercial purposes. It is an enormous undertaking and will take years to complete. In the meantime, and afterwards, the fear of spectrum "shortages" persists. Few in Washington are willing to ask the tough question: Why is there a "shortage" of spectrum? The answer is not the finiteness of spectrum as no one focuses on a "land shortage" or a "copper shortage."
Ask any student of introductory economics--at least those who stayed awake through part of the classes--about shortages, and they will know the answer. In a well-functioning market, shortages simply do not exist. At a market-clearing price, demand just equals supply. If there were a "shortage," i.e. less supply than demand, prices would be bid up to the point where the market would clear. Prices of spectrum are highly volatile, moving in dramatic short cycles, but on an upward trend. Prices are up, yet spectrum is still widely described as having a "shortage." Why? Should prices increase further?
The only reason we can have "shortages" in a market is because the market is not functioning well. Perhaps the most common reason for "shortages" is the government prevents markets from responding to price signals. Sadly, that is precisely the situation with spectrum: the government is standing in the way of the market.

OpenRadio changes what it means to be an ISP
The havoc that OpenFlow is wreaking in the data center along with its promises for home broadband networks may change the way we think of Internet service providers and in the process solve the spectrum crisis. OpenRadio is a project from Stanford that hopes to use OpenFlow to create pools of available broadband from Wi-Fi, cellular and other networks. The project team is working with Texas Instruments to build $300-$500 base stations for the hardware component, while researchers try to build the orchestration software.
Sachin Katti of Stanford presented the OpenRadio idea at the Open Networking Summit held in Santa Clara, Calif. this week, and laid out a clear rationale for using a software-defined network to aggregate all the available wireless technologies together to deliver services. By layering the orchestration software on top of the networks, operators can easily write programs that can help them optimize their networks. For example, an operator could limit Netflix or YouTube traffic to only 40 percent of the LTE airwaves and save the remainder for other data traffic and voice.

Accommodating M2M applications in underutilised spectrum in bands assigned for other primary uses appears to be an ideal way to meet their growing demand. Wi-Fi currently operates in licence-exempt spectrum (at 2.4GHz or 5GHz), but with the 2.4GHz band becoming increasingly congested, there is commercial interest in extending into other bands. In particular, bands below 1GHz are attractive, because of their greater range and indoor penetration (into buildings).

Wifi Hot Spot List

Loki software www.loki.com has created WiFi maps of the nation's 100 largest cities, with precise locations for five million wireless data signals. Loki uses these wireless signals to tell users with WiFi laptops where they are -- and where they can obtain a variety of products and services. Anybody with a WiFi-equipped portable computer that runs Microsoft Corp.'s Windows operating system can use Loki, downloaded onto your pc.

US company offers Wi-Fi-proof paint
An American company says it has successfully tested wireless-blocking paint. EM-SEC Technologies, in a release last week, said its "Coating Solution", applied to a test facility, had successfully protected "wireless devices and other electronic equipment". According to the company, "a one-time application of the coating creates an 'electromagnetic fortress' by preventing airborne hackers from intercepting signals". EM-SEC reckon this would be useful for corporate offices, boardrooms, server and computer rooms, and R&D labs. It seems that wireless nets can be operated without trouble inside a painted building or room.

"Google is arguing that it did nothing wrong in sucking up sensitive information from unsecured Wi-Fi networks. Google says that anyone using such a network is essentially broadcasting their online activity on a radio channel, and that tuning in shouldn’t be illegal."

Wi-Spy Google Engineer Outed As 'Hacker' 'God' Marius Milner
When the Wi-Spy mess was originally revealed in 2010, Google said it was an accident, due to code mistakenly created by a rogue engineer. But subsequent federal investigations into the incident revealed that Milner clearly stated his attentions in design documents (that his supervisors claim they didn’t read). He hoped the snapshots of where people were and what they were doing might be useful for other Google projects. Milner, now an employee at YouTube, is thought of as a “god” among engineers for creating NetStumbler, a tool for detecting wireless access points. On a LinkedIn page that has since been taken down, he described himself as a “hacker” who knows “more than I want to about Wi-Fi,” reports the IBTimes. Meanwhile, Geekwire reports that Milner is listed as an inventor on a Google patent filed in 2007 for technology to protect against “hackers and other ne’er-do-wells [who] may seek to tap into communications on a network.” *Irony alert*
