If you have a cell phone that is WiFi ready then you may be able to make calls, text, and do a number of other things without using any minutes or being charged by the cell phone company.Many times these WiFi cell phones will have features that people will be unaware of that will allow them to connect up to a wireless network and start talking for free.

How A WiFi Cell Phone Works

The way a WiFi cell phone works is that it will connect up to a local available wireless network then use some other service to make a voice over IP conntection to the phone number.  What this means is that any calls you make will be completely free of charges from the cell phone company because you are not using their service at all.  While the quality of these WiFi cell phone calls may not be as high as what you would see using your normal cell phone, they are more then adacuate for making calls on a regular basis when you simply need to talk and do not want to pay much for it.

Voice over IP will usually have a bit more lag then a normal to cell phone connection, but for the most part this is not significant.  The key is that you need to make sure that are able to run service on your phone to use the WiFi connection to talk.  Some may not have the ability be a WiFi SIP phone, Skype or any of the other programs that are available.In addition the strength of your connection will be dependant on a couple of factors.  The first is how good the wireless is in the WiFi cell phone.  I would recommend if you intend to use your cell phone for this making absolutely sure that it has at least wireless G.  Wireless N would be great, but those phones can be incredibly expensive.

This will ensure not only that you have the bandwidth to make the call but also that you have a strong signal strength and range to make it reliable.Voice over IP does not require a huge amount of bandwidth so the more important part is that you have a nice strong single and you are not getting disconnected frequently.By getting at least a G phone you can make sure that this will be the case.

There are some things you may not be able to do with a WiFi cell phone.  The first of which is receive incoming calls.  While you will be able to get incoming Skype requests, to get an incoming call form a land line will be a problem.  It is however a great tool for making outbound calls.

There are many electronic gadgets on today’s market that are available to the consumer.  Some of these electronic gadgets are designed for entertainment purposes and some of these electronic devices are designed to streamline one’s busy schedule.

One such electrical device that is designed with the busy person in mind is the PDA.A PDA stands for personal digital assistant.Specifically, a PDA is a hand held organizer that is a standardized with certain functions already installed on the device. 

Also, there are other peripheral applications that may be incorporated on a PDA.  One of those productive applications is WiFi or wireless fidelity.  This is an application that is either built into the PDA or has the capability of hosting a WiFi card.  This WiFi capability allows the user to utilize the internet through their PDA or some organizers have PDA GPS Wifi capabilities which are extremely helpful for business travelers.

Therefore, if considering the purchase of a fully functional PDA it is important to consider the WiFi application.  Subsequently, when considering this application, it is import to know how a PDA WiFi works and whether one wants a built in PDA WiFi or not.

How A PDA WiFi Works

First of all, when in the market for a personal digital assistant, it is important to know whether or not the unit is equipped with WiFi.  This can be easily accomplished by conducting research on a number of units and looking to see what the particular specifications of the PDAs are.  Generally, the specifications list whether or not it has the capability of WiFi.

Once the potential buyer has established that the unit is WiFi capable and is purchased, then the unit is simply powered and the owner goes to the WiFi setup icon on the application display.  Often, the screen is sensitive to touch and is activated through the use of a stylus.  Simply tap the WiFi setup icon with the stylus and follow the instructions that are displayed on the screen. 

Eventually the screen will display networks that are available to the user so that they can access that network and go online.It is also very important to note that many of the networks that are displayed on the WiFi setup screen will have a lock icon displayed next to the systems that have been identified.  Therefore, unless the individual has permission to access these networks, they will be locked out from gaining access.

Following this step, the individual, using the stylus, taps the network of choice.  Following this step the screen will display whether or not the WiFi setup is complete and whether an internet connection has been establish.   Once the setup is finished the PDA Wifi can be used to go online by tapping the internet browser icon on the unit.

Maybe With or Without

One other important aspect of utilizing a PDA WiFi is whether the consumer wishes the WiFi card to be installed internally on the PDA. The main advantage of having the card internally installed on the PDA is that the unit is ready to go in any given moment without having to insert the WiFi card.However, it is important to note that these units are much more expensive because of this added internal application.

On the other hand, the purchase of an external WiFi card is an additional cost and therefore, it is important for the consumer to note that once the card has been purchased they may eventually reach the same total buying cost as if they were to buy the WiFi card separately.
