Welcome to voip architecture.

This web site has been designed with the sole intention of providing one-stop information about Voice over Internet Protocol (VoIP). All the information on this site has been collected by doing a careful and in-depth research on the internet about VoIP and presented in a very user friendly manner. We are in the process of compiling VoIP comparison of services provided by major companies in the industry.

Prior to the advent of internet interactive communications were only made by telephone at PSTN line cost, which was very expensive especially over long distances. With the advent of highly advanced network technology and computers being massed produced and available to consumers at a lower; people begun to communicate with new services like email, chat, etc. These services were extremely cheap and easy to use but lacked the personal touch provided by telephone. Therefore big corporations began to fiddle with the idea of allowing people to have real-time vocal communication and thus beginning a totally new chapter in internet history: VoIP.

What is VoIP? (Definition of VoIP)

As stated above VoIP stands for Voice over Internet Protocol and is a technology for transmitting ordinary telephone calls over the Internet using packet linked routes. VoIP is also referred to as IP telephony. VoIP involves the transmission of telephone calls over a data network like the Internet. In other words, VoIP can send voice, fax and other information over the Internet, rather than through the (PSTN) or regular telephone network. A major advantage of VOIP and Internet telephony is that it avoids the tolls charged by ordinary telephone service. VoIP telephone calls (voice) bypass the typical public-switched telephone network and transmit voice calls over a private network (the same network that carries web, e-mail and data traffic). In General Voice over Internet Protocol (VoIP) refers to the use of the Internet for making telephone calls. The main advantage for users of VoIP connections is that they generally only have to pay their usual (local) Internet connection charges regardless of where they are calling anywhere in the world. VoIP telephony hence threatens the traditional distance and even time-based pricing model upon which all major voice line telephone services are currently based.

How does VoIP work?

VoIP generally work on the established methods of sending packed digitized data over the internet. TCP/IP networks are made of IP packets containing a header (to control communication) and a payload to transport data: VoIP use it to go across the network and come to destination. While sending information analog data is digitized with the help of an ADC (analog to digital converter), transmitted and then at the other end the data is again transformed in analog format with DAC (digital to analog converter) to use it. VoIP also works in very similar manner. VoIP digitalizes voice in data packets and then sends them to the destination and reconverting them back to voice at destination.

Voice at the Source -> Digitized using ADC -> sent over Internet -> Digitized Data Received at Destination -> Data is reconverted to Voice using DAC.

Bluetooth - Discover the Magic of Wireless Technology
By Chonticha Marijne

Bluetooth technology got its name from the Viking King Harald Bluetooth of Denmark, who was famous during his time for his excellent mediation skills. He connected with a lot of people and was admired by his men for this talent. Hence, when the technology was invented, the name stuck.

This wire free technology enables a broad selection of devices to be able to exchange information with the help of 2.4 GHz short-wave radio signals within a range of up to 120 feet. Devices like video game consoles, mobile phones, PCs, laptops, PDAs, MP3 players, stereo headsets and printers all can be connected to each other through Bluetooth. 

Technology has made our lives so much easier and Bluetooth is one such invention. The best thing about Bluetooth is that you can connect any two devices without using any wires. The wiring of the computer with various other devices like the fax machine, printer, Internet server can sometimes be a nuisance.

Thanks to Bluetooth technology, pesky wires are no longer required. This technology can connect laptops, headphones, PDAs, cell phones and printers. And now, you can set up your own PAN (Personal Area Network) where you can be linked to other laptops, cell phones, printers, etc. as long as the other devices used are also Bluetooth enabled.

The Bluetooth keyboard and mouse are some of the best applications of this technology, as it makes it easy for people to use their computers. With Bluetooth technology you can have hands free communication; you can now take your phone calls while driving, cooking, jogging, etc. and you can listen to your favorite tunes within the house without that cumbersome cord getting in your way.

Even if the appliances and devices that you already have at home do not have in-built Bluetooth technology, you can upgrade them with the help of a USB Bluetooth adapter, commonly known as the Bluetooth dongle. Bluetooth technology is excellent for multiple users sharing a common device. For example, a good number of computers can use the same printer without having to be connected to it with wires.

The Bluetooth technology products are also very reasonably priced and everybody can afford them. Because 2.4 GHz, the radio band where Bluetooth operates in, is an unlicensed industrial, scientific, medical (ISM) radio band, there is no cost for the use of Bluetooth technology. You pay for your device and it is definitely worth every penny.

Bluetooth is tomorrow's technology, available today. Discover more about the freedom of Bluetooth, such as the Bluetooth headset at http://WirelessRevealed.com. Article Source: http://EzineArticles.com/?expert=Chonticha_Marijne




Keep An Ear On The Future With A Bluetooth Headset

Bluetooth headsets, whether the kind used for phone conversations or the double-eared variety for listening to music, pod casts, and so forth, are gaining in popularity. In fact, Bluetooth headsets, which were not even around a few years ago, seem to be on

everyone’s head or in their ear. Interestingly, the technology used to develop Bluetooth headsets is somewhat similar to the technology we are already accustomed to and literally cannot live without. The nice thing about Bluetooth headsets, though, is the quality of sound. In fact, the sound is so clear and crystalline that it is almost unbelievable that there are no wires, cords, or cables involved.

That is right—no cords. No cables. No wires. Bluetooth headsets utilize wireless technology, similar to that of radio controlled items. Think about your cell phone, your cordless home phone, or even your children’s walkie talkies. These electronic devices are using wireless technology to send information to and from different devices. It is not so implausible, then, that the wireless features we have come to expect, to demand, even, are getting better all of the time.

Bluetooth headsets are among this new breed of wireless pieces that allow the user to move freely, as long as the Bluetooth headset is set to a coordinating channel of radio frequency as the device to which it is supposed to communicate. Bluetooth headsets can be connected to the home computer, to an iPod or MP3 player, to a cell phone, and even to a stereo. The static or interference normally associated with loose wiring connected to headphones is a thing of the past, as the Bluetooth headset communicates via radio frequency to deliver the clearest sounding music and voices than are even possible in face to face interactions.

Another feature of the Bluetooth headsets on the market now is that, unlike those cordless home phones, cell phones, or really anything else that uses wireless technology, there is a surprisingly low energy output, so recharging the batteries does not have to happen as often as, say, your cell phone. Bluetooth headsets, then, with their high efficiency and outstanding clarity, are another item on the “I NEED THAT” list. Going cord and cable free is a huge benefit. Suppose that you are up late at night, downloading music to your PC. You don’t want to wake the house, but you really need to preview the songs before purchasing them, right? A Bluetooth headset will allow you to move about your home office, listening to the music, without blaring it through your computer’s speakers.

Bluetooth headsets are able to be used in conjunction with a variety of other devices, so long as those other devices are what are known as Bluetooth compatible. You may have noticed, especially if you have purchased a cell phone in the last year, that Bluetooth compatibility is a marketing point. This is because so many people have realized the benefits of this cutting edge wireless development. Crystal clear sound, long battery life, and, of course, reasonable prices, makes wireless Bluetooth headsets the hot “must have” item.

Bluetooth Proximity Marketing

Bluetooth Proximity MarketingBluetooth technology is now the latest medium for advertising and marketing. Bluetooth proximity marketing has become all the rage overseas as the newest way to connect with potential or existing customers.

The definition of proximity marketing via Wikepedia.com is “the localized wireless distribution of advertising content associated with a particular place. Transmissions can be received by individuals in that location who wish to receive them and have the necessary equipment to do so.” In other words, if you have a cell phone in the proximity of a marketing broadcast, you would be able to receive the message or advertisement.

Here’s how it works. Imagine you’re walking through a mall, and you pass a proximity broadcast station. The key is to have your phone on and in “discoverable” mode. This will allow all possible ads in the area to “hit” your phone – asking if you want to receive free content from the provider. For example, say you’re shopping for gym equipment at a specialty shop and they have a proximity marketing station set up. If your phone is in discoverable mode, you’ll receive a message asking if you want to receive free content from “ABC Company”. Think of it as a virtual billboard or flyer advertisement.

Bluetooth ProximityThis form of advertising has been in use for quite some time in Europe, as well as various other overseas locations. There are dozens of companies already in full swing of promoting Bluetooth proximity marketing, with many more in the start up phase here in the United States today.

Proximity marketing can also be received via laptop or PDA. The range and accessibility to most Bluetooth proximity marketing depends on your equipment, many which don’t require pairing for receipt of text or graphics. The average range of Bluetooth proximity marketing is 100 meters, although with advances in technology, this distance is increasing. Although some critics of the technology claim this as a potential problem, we can refer to the virtual billboard idea. The billboard doesn’t move with the driver as they pass it on the road, but looks for an instantaneous response to the ad in the general vicinity. The same is true of proximity marketing.

Going paperless has been a concept for so long that it can be taken for granted in most businesses. Bluetooth proximity marketing is simply the next technological step for businesses to take.

Accessories For Your MP3 Player

By: Eddie Lamb

If it's hard to choose an mp3 player these days, it's getting to be just as difficult to choose the accessories for it as well. First of all, we'll start with what kind of accessories that are available.

Speakers and Headphones

These are the accessories that count the most when talking about the listening experience of your music or audio books. Even if the original manufacturers might not supply quality or comfortable headphones with the player, there are many other companies that will offer you some of the best portable speakers, ear buds or headphones. These are specially created to offer you amazing audio quality and are worth the extra price.

Batteries and Chargers

Flash mp3 players (the models that work with an embedded memory chip) usually need AA or AAA size batteries. However, if you're using your mp3 for extensive period of times, you will need to change the batteries quite quickly. This might not be at all convenient to you and can also be costly in the long run. A quick fix is to use a charger and rechargeable batteries.

Most hard drive mp3 players (the models that hold the memory on a hard disk) have a built in lithium-ion rechargeable battery. These models need a special type of charger and cable to recharge, but they are usually included in the pack when you buy it.

Armbands

Armbands are ideal if you want to use your mp3 player while walking, running or exercising. However, you need to choose the right armband for the exact model that you have. Click Here to Buy Apple iPod Armbands 

Adapters and Cables

You need a cable or an adapter if you want to connect your mp3 player to your car, your PC or your stereo system from home. Most of the time, a USB cable will do the job.

Docking Stations

Besides the headphone jack, not all models of mp3 players have other needed output connections. In this case, you will need to separately buy special adapters and cables, or a special docking station for iPod, for example.

The docking station can also act as a charger for the battery, it has a remote control and sometimes even output connections for video.

However, a docking station is an extra expense, as very few manufacturers will offer a dock in the same package with the player.

Bags and Cases

You can use hard cases, plastic or leather cases and bags. The plastic cases are the most used, as hard cases are not always easy to use, and leather cases and bags are trendy, but they will not protect your mp3 player all the time.

Now you know what kind of accessories you can have for your favorite mp3 player. As with any product, it is wise to shop around because you can stumble on a great bargain. So ... happy shopping!
