    Are Internet Service Providers Blocking VoIP?

    October 16th, 2008

    Having used VoIP problem free for for a good few years I was confused as to why out of nowhere I had been having lots of issues. Sound quality has massively deteriorated and latency issues have become markedly noticeable. Users on VoIP online forums in the US and other countries, including Spain and Mexico, have been noting similar problems since last year. For a while VoIP might seem like a good deal for the average person, more established interests in the telecoms industry view it differently - and are trying to make a stand.

    Consultation

    knowledgeable of what has happened elsewhere the UK telecoms regulator Ofcom took the decisive step in February of announcing that it will look at the increasing Voice over IP industry and report next month on whether new laws are needed to shield it. The consultation document says: “VoIP service providers have expressed concern that their ability to provide a reliable service may be impacted by internet access providers (ISPs) selectively degrading or blocking their VoIP traffic.”

    Ofcom says it has no evidence this is happening in the UK; only about 000 customers use Voice over IP services. But the forecast is for that to rise by 4m in the next six months.

    And VoIP blocking occurs in other countries, more often than not those where there is still only a single telecoms company. In Saudi Arabia, for instance national carrier Saudi Telecom is using software from US supplier Narus to block all Voice over IP phone calls.

    Telecommunication companies in the US as well as other countries are reluctant to have their bandwidth taken up by traffic from which they earn no revenue and have been challenged over similar alleged incidents of VoIP barring. Hindering VoIP traffic is technically difficult but not illegal and barring precise kinds of internet traffic is on the increase.

    The European based VoIP giant Skype who are now owned by eBay has been particularly controversial. Skype is used by 75m people. But not everyone wants Skype on their network.

    Skype is considered by a lot of people to pose a potential security risk as it creates an encrypted tunnel out of the network and forms supernodes that sit on a network and connect internet telephony calls. There is considerable debate about how much bandwidth such supernodes eat up. There have been warnings that in supernode mode, Skype may even saturate a 100 Mbps line.

    The Fantastic Futuristic Features of the GPS System

    June 29th, 2008

    Man has always speculated about what lies beyond his immediate circle of knowledge. Many a journey has been taken and many a new land has been discovered all because of man’s curiosity. The uncertainties faced and risks taken in the name of adventures and travel has claimed many lives. Navigation and maps are vital to these activities.

    Luckily for us, we live in an age of new and innovative ways for technology to help us and one of them is the GPS system.

    Global Positioning System (GPS) is a worldwide navigation system formed from a constellation of 24 satellites and the associated ground stations. There can be more than 24 operational satellites; new ones are launched periodically to replace older satellites.

    Each satellite orbits continually about the same ground track (as the earth turns beneath them) once per day, at an altitude calculated to ensure the satellite repeats the same track over all points approximately each 24 hours (actually 4 minutes earlier each day).

    There are six orbital planes, equally spaced (60 degrees apart), and inclined at about fifty-five degrees with respect to the equatorial plan. The GPS system uses “man-made stars” as reference points to parse accurate positions to within meters.

    The GPS system in it’s entirety is comprised of a network of satellites, signals, support personnel, ground based hardware and software, which make possible the establishment of one’s precise location on the Earth’s surface. The Global Positioning System is funded by and overseen by the U. S. Department of Defense (DOD). While there are many thousands of civil users of GPS world-wide, the system was designed for and is operated by the U. S. military.

    The accuracy of location measurements using the global positioning system depends on the GPS receiver. High-end, survey-grade GPS receivers can determine locations precise to within centimeters. But even low-end, handheld consumer receivers, can be accurate to within fifteen meters. GPS receivers have been miniaturized to just a few integrated circuits and so are becoming economical and readily available.

    The first commercial global positioning system units were precise for only about 100 meters because the military scrambled the signal–a program called Selective Availability. In the year 2000, the U.S. government removed Selective Availability, improving the accuracy of even basic handheld units to within fifteen meters. Today, with additional information from ground based correction services such as WAAS WAAS (Wide Area Augmentation Service) or U.S. Coast Guard differential GPS beacons, accuracy can be improved even further.
