Personal Wireless Networking

If you’ve got a wireless network for your computers already, well, you might get a bit excited about what I’m going to say next. How would you feel if your PDA, your mobile phone, your mp3 player and almost everything else you connect to your computer could be wireless too? You’d like that? Well, it’s already a reality and has been for some time now.

Bluetooth is wireless and automatic, and has a number of interesting features that can simplify our daily lives. Bluetooth is a standard developed by a group of electronics manufacturers that allows any sort of electronic equipment — from computers and cell phones to keyboards and headphones — to make its own connections, without wires, cables or any direct action from a user. Read on…

Personal Area Network.

Using wireless networking with your personal gadgets is often called PAN, which stands for Personal Area Network. The idea is that, in the future, we’ll all have laptop computers with their batteries charged and no more need to connect any wires to them at all — you just place your Bluetooth device near the computer, and the computer sees it and can use it straightaway.

Bluetooth has been around and in-use since 1999, and it’s only getting more popular. It was designed to be secure, low cost, and easy to use from day one.

There are two classes of Bluetooth that are in popular use: class 1 and class 2. Class 2 is the most common and cheaper standard, allowing you to use a device that is up to 10 metres (32 feet) away. Class 1 is rarer, but you can still find devices that use it easily enough, and it has ten times the range: 100 metres or 320 feet.

How SMS Works

SMS, or Short Message Service, is the technology behind what we often refer to as ‘text messages’ or ‘SMSes’, as well as what allows for news alerts on cellular phones. In recent years SMS has ballooned to over a 50 billion dollar industry and is quickly taking the communications world by storm.

Short Message Service actually refers to a framework that uniquely allows computers, or in this case phones, to communicate with each other without the need of a central hub. With SMS, phones can find each other, send short packets of information back and forth, and do it all without any central computer to guide them. But because the system does not rely upon fixed lines like a land based telephone system does, the amount of information that can be sent at one time is limited in size. This depends on the language spoken, but for English letters this typically means around 150 characters (Chinese and Japanese letters are limited to 70).

Quite recently, however, new developments in the technology have allowed for even longer messages to be sent. Long or Concatenated SMS is a development that allows multiple messages to be combined to form a single message. In effect, what happens is that your phone actually sends out a few smaller messages and then the receiving phone simply compiles those messages so that for users on both ends, it appears as though the message were cohesive. While there are some limitations, the brilliance behind SMS is that because there is no need for central hubs, and thus the system can be expanded indefinitely without any concerns of it slowing down or becoming more expensive.

Computer Phones – Facts and Fallacies

The stakes are high when considering security, privacy, and savings, and the old adage, “look before you leap” might be a more judicial approach when searching for a computer phone provider, aka VoIP (voice over internet protocol).

FACTS

o PC phones (VoIP) can save individuals and businesses up to 80% on current phone bills, regardless of whether calls are made from PC to landlines or mobile phones.

o Secure lines that include patented technology are protected against terminal viruses, worms, Trojan horses, unscrupulous hackers, and uninvited guests listening in on private conversations.

o Unsecure lines cripple users by creating dangerous vulnerability to security and privacy due to operating on open platforms or shared services.

o Over 90% of all VoIP provider services are on unsecure lines.

o Greater than 90% of VoIP solutions providers DO NOT HAVE their own patented technology.

o Costly computer crash repairs have resulted from using unsecure lines.

o Sound travels faster over the internet versus traditional phone lines.

o VoIP requires an inexpensive microphone when not built into the computer.

o There is usually an activation fee.

o Numerous VoIP providers host hidden costs.

o Most VoIP providers charge for de-activation.

o Some VoIP provider require a contract.

FALLACIES

o Broadband or high speed internet connections are the base requirements for VoIP connections. (There are a few VoIP solutions providers with integrity, security, and patented technology that offer service for dial-up connections, as well as DSL, satellite, cable, and broadband connections).

o All well known phone services now offering VoIP have their own patented technology (over 95% do not).

o All well known phone services now offering VoIP incorporate secure lines (over 90% do not).

o Using an open platform is safe.

o Peer-to-Peer services are on secure lines.
