UK wireless broadband provider 3 has announced real speeds for its improved networks. The company is more precise and circumspect about its upgrade schemes than other providers who advertise mind-boggling speeds that customers never experience.

The company already has a 3.6Mbps network in place and is in the process of taking it to the next level of 7.2Mbps.

Although the company has recently upgraded almost 40 percent of its network to the new 7.2Mbps, it admits that the projected speed is just a technical marker. It has asked subscribers not to confuse between the advertised speed and the actual speed, which is lower than the former in almost all cases. The company has said the advantage of the upgrade is that more people will now have access to broadband with speeds between 1 to 2Mbps.

The provider has also pointed out that not all customers will be able to use faster internet speeds in the new 7.2Mbps network. It has said customers will have to be present in areas where network signals are excellent and also use high-speed dongles to benefit from the new upgraded network.

The straightforwardness of 3 in today’s competitive world is definitely commendable. The company, by upgrading its service, wants more people to access broadband from their offices or homes, rather than making any tall claims to provide the highest broadband speed. 3 confesses that applications requiring high bandwidth or quicker data speeds will not be supported by its network, and its frank and honest approach is sure to win many new customers who are otherwise dissatisfied with broadband services never fulfilling their advertised claims.

Recently many people have argued that mobile broadband has reached a stage in Sweden where it can replace fixed line broadband. Reports of the Swedish Post and Telecom Agency state that the traffic of data in the country’s mobile broadband network has grown four times. Further data consumption by mobile broadband subscribers has also grown to almost double last year making many believe that this replacement is possible.

Sweden is considered as one of the topmost countries in usage of mobile broadband. Recently, a senior partner of Rewheel, a telecom consultancy from Helsinki, said that the data shows the future possibility of mobile broadband and its capacity to supplant fixed line broadband.

This fast change has been due to mobile broadband in Sweden being comparatively less expensive than fixed line broadband. Owing to competition between service providers, the prices have come down, thus allowing many to avail the technology - click for mobile broadband reviews of UK service providers.

However, the same low prices may upset the profit margin of the companies, as they will try reducing prices further to unsustainable levels in order to attract more subscribers. Undercutting will be bad for the industry and thus, before mobile broadband can become a substitute for fixed broadband, it is important to have a price structure in place in order to protect the industry.

A bright future awaits mobile broadband if a recent report released by Juniper Research is to be believed. The telecom research and analysis company has attempted to chart the future of LTE, the technology that is being seen as the next generation of mobile broadband and is expected to completely transform the mobile data services market.

The telecom industry is also of the opinion that Long Term Evolution, which is theoretically capable of speeds of 100Mb, is the gen-next of mobile broadband.

LTE is likely to cross the $70 billion mark globally within five years and is being seen as a catalyst for bringing mobile communications and consumer electronics within touching distance. To illustrate this point the report gives the examples of digital cameras and games consoles, which could be made capable of connecting to the internet as well as interacting with each other through mobile communication.

The report by Juniper Research advises that mobile providers must be careful about the business model that they use to commercialize the technology to ensure both profits for themselves as well as a price that would suit the budget of the consumers.

Taking an upbeat view, the report also claims that recession is not expected to affect the long-term prospects for LTE; however, in the short run, the growth of the technology could suffer as investments will be reduced and operators will be hesitant to start major projects.

Having made calls using VoIP without issue for for ages I was baffled as to why out of nowhere I had been having lots of issues. Sound quality has reduced and latency issues have become markedly noticeable. Users on VoIP online forums in the US and other countries, such as France and Mexico, have been noting similar issues since last year. For a while Voice over IP might seem like a good deal for the average person, more established interests in the telecoms industry see it differently - and are doing something about it.

Consultation

Well aware of what has happened elsewhere the United Kingdom telecoms regulator Ofcom took the unusual step in February of announcing that it will look at the growing VoIP industry and report next month on whether new laws are necessary to protect 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 it. But the prediction is for that to go up by 4m in the next six months.

And VoIP barring takes place in other countries, more often than not those where there is still only a single incumbent 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.

Telcos in the United States as well as other countries are hesitant to have their bandwidth used by traffic from which they earn no revenue and have been challenged over similar alleged incidents of VoIP blocking. Barring VoIP traffic is a challenge but not illegal and barring precise kinds of internet traffic is going up.

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

Skype is considered by a lot of people to pose a potential security threat because it creates an encrypted channel out of the network and forms supernodes that sit on it and set up VoIP calls. There is big debate about how much bandwidth such supernodes eat up. There have been claims that in supernode mode, Skype could possibly saturate a 100 Mbps line.

GPS, or Global Positioning System, is the latest thing in keeping from getting lost when trekking out to visit your Aunt Louise. Years ago you had to rely on landmarks, your handy compass or the guy at the corner gas station, assuming he knew where everything was. Today for about a hundred bucks you can get a little gadget that will tell you exactly where you are, any place on Earth. By using some basic mathematical calculations and a rather complex system, you can be in the middle of the desert, lost as can be, push a button and have your GPS tell you exactly where you are so that you can hopefully find your way back home.

So what exactly is GPS and how does it work?

GPS is actually a very complex and expensive system but the fundamental concepts of the system are very simple.

The GPS system is a group of 27 Earth orbiting satellites. Twenty-four of them are in operation and 3 are backups in case one fails. The system was originally created for the US military but was eventually opened up to everyone else.

Each one of these satellites, weighing in at about 4,000 pounds, circles the Earth at about 12,000 miles per hour and makes 2 complete rotations everyday. The orbits are arranged so that at any one point in the day 4 of these satellites are visible from any place on Earth.

The complimenting receiver that was created to receive signals from these satellites has the job of locating 4 or more of these satellites, figure out the distance to each and from that information determine where on the planet the receiver itself is located. It then transmits this location back to the person who happens to be in possession of the receiver. The operation is based on a simple mathematical principal called trilateration. To simply explain how this works, let’s say someone tells you that you are 10 miles from Newark, NJ, another person tells you that you are 15 miles from Maplewood, NJ and a third person tells you that you are 20 miles from Woodbridge, NJ. By taking those three facts you can figure out exactly where you are because each radius of each distance when linked together will intersect at only one point. That point is where you are located.

In order to actually do the calculation from space the GPS receiver needs to know 2 things. The location of at least 3 satellites above you and the distance between you and each of those satellites. The reason that only 3 satellites or spheres are needed is because the Earth itself can act as a fourth sphere. The GPS receiver itself works by radio waves which are a kind of electromagnetic energy and travel at the speed of light The receiver can actually figure out how far the signal has travelled by timing how long it took for the signal to arrive from each of the satellites.

In the next article on GPS we’ll go over exactly how this system works to measure distance.
