VOIP lets you make toll-free long distance voice and fax calls over existing IP data networks instead of the public switched telephone network (PSTN). Today businesses that implement their own VOIP solution can dramatically cut long distance costs between two or more locations. For the past 100 years people have relied on the PSTN for voice communication. During a call between two locations, the line is dedicated to the two parties that are using it. No other information can travel over the line, although there is often plenty of bandwidth available. Later, as data communications emerged, companies paid for separate data lines so their computers could share information, while voice and fax communications were still handled by the PSTN.
Today, with the rapid adoption of IP, we now have a far reaching, low-cost transport mechanism that can support both voice and data. A VOIP solution integrates seamlessly into the data network and operates alongside existing PBXs, or other phone equipment, to simply extend voice capabilities to remote locations. The voice traffic essentially “rides for free” on top of the data network using the IP infrastructure and hardware already in place.
the idea of VoIP is the hosted PBX. The IP-based PBX is usually software running on a computer based server. However, it often requires a forklift upgrade of the existing PBX, or at a minimum, an extensive software and/or hardware upgrade. An IP-based PBX is typically marketed to new installations where no legacy system is in place.
Ten years ago, who had thought there would be a small device in our hand giving so much within no time? Certainly, mobile phones have brought a paradigm shift in the history of technological development in the present era. Nokia has been the ambassador of all these changes coming with an array of innovative and entertaining handsets. “Nokia N series mobile phones” is the name of a new revolution in the coming future.
it has been a long time now since the launch of the first N-Series mobile handset. However, the N-Series after-effect is still very strong in us. We still can’t forget how radically our vision towards mobile phones did change with these brand new mobile handsets. All the handsets featured in this series are empowered by the latest in mobile telecommunication technology; in addition, they are stylishly designed and easy to use!
The Nokia N series mobile phones range is an iconic example of the fastest growing product category in the mobile space. The new addition in Nokia N series family include Nokia N95, Nokia N96, Nokia N98, Nokia and N96i. Nokia boasts of calling these handsets as the music phones which gives a new dimension of listening music on a phone. The recently launched Nokia N95 is the best manifestation of Nokia’s cutting-edge technologies till date. The handset resembles a miniature computer mainly because of its power and capabilities. An integrated 5 megapixel digital camera with auto focus, digi Continue reading »
The broadband technology in its inception has further ‘broaden and widen’ the so-called “information superhighway” allowing smooth traffic of all medium of data (voice, audio, graphics and video) with freer and faster access from their source to their destination. Major players of this technology are the Telecom and Digital Broadcasting Service (DBS) providers.
The broadband technology has created a lot of multiplier effects in the adjoining ICT technologies (Information, Communication and Telecommunications technologies) used in delivering service to their teeming subscribers. The main stream of this arrangement are the copper lines, cable-, modems and telephone-network upgrades are proceeding at varying speeds, depending on the company.
The responsibility lies on service providers to iron out any number of technological issues with the economies of scale in the broadcast and transmission distribution network before they can provide seamless, bug-free service in line of this new dynamic technology.
This consideration and the attendant deployment of the arrived business decisions on the chosen technology gave rise to digital satellite broadcasting and the rapid expansion of voice over IP (VoIP) technologies.
Also it further the growth of Wireless service providers, whose sector found the ways to speed the upstream, or return-path, delivery of data (data, voice and video)making the choice and option more attractive Continue reading »
The television, it is safe to say, has become firmly entrenched in modern day society. No other medium is as widely used – television ranks first, with computers and the radio coming second and third respectively – or appeals to such a wide range of age groups and interests. It is no surprise then that the broadcasters have worked hard to ensure television continues to provide a relevant level of service to its viewers.
One of the most notable developments in the history of the television is digitisation. No longer as limited by size, broadcasters have found that by switching to digital the channels take up less bandwidth, meaning it’s possible to provide more content within the same space. Not only that, but they can also offer the viewer additional multi-media services, which has led to a much greater level of viewer interactivity.
According to the latest statistics, seven countries, including America, Germany and Luxembourg have already changed from analog terrestrial broadcasting to digital transmission. Many others, like the UK and Australia are currently in the process of switching, and it is expected that most other countries will follow suit within the next decade.
This switch from analog to digital highlights the fundamental change television has undergone since its first appearance in the early 1900s and serves to show how the relationship between broadcaster and viewer has altered. Indeed, in contrast to merely being broadc Continue reading »
