Bluetooth Connectivity

When you use computers, entertainment systems or telephones, the various pieces and parts of the systems make up a community of electronic devices. These devices communicate with each other using a variety of wires, cables, radio signals and infrared light beams, and an even greater variety of connectors, plugs and protocols. Driver access is needed to operate these electronic devices.

There are lots of different ways that electronic devices can connect to one another. For example:

* Component cables

* Electrical wires

* Ethernet cables

*WiFi

* Infrared signals

The art of connecting things is becoming more and more complex every day. In this article, we will look at a method of connecting devices, called Bluetooth, that can streamline the process. A Bluetooth connection is wireless and automatic, and it has a number of interesting features that can simplify our daily lives.

When any two devices need to talk to each other, they have to agree on a number of points before the conversation can begin. The first point of agreement is physical: Will they talk over wires, or through some form of wireless signals? If they use wires, how many are required — one, two, eight, 25? Once the physical attributes are decided, several more questions arise:

* How much data will be sent at a time? For instance, serial ports send data 1 bit at a time, whil­e          parallel ports send several bits at once.

* How will they speak to each other? All of the parties in an electronic discussion need to know           what the bits mean and whether the message they receive is the same message that was sent.            This means developing a set of commands and responses known as a protocol.

the Right Card for Mobile Internet

Once deciding to purchase a Mobile Broadband Card for you laptop there are still several choices to be made. The first is: Which Carrier to get?

Since Sprint & Verizon are generally considered the leaders in this technology, we will limit the discussion to these two choices. As far as monthly pricing goes they are exactly the same, $59.99 a month. However, there is a very important distinction. Sprint offers truly Unlimited service for businesses and a 5GB limit for individuals, where Verizon has a 5GB limit per month for all customers. For the casual user this is plenty of data, but for a power user, Sprint clearly is the better choice here.

The other factor is coverage. Both carriers are going back and forth with their claims of “more coverage”. The best thing to do is check the coverage maps and see who has the most Rev A coverage in the areas you need service. Rev A is the fastest service currently available, so go with the carrier that covers you the best, but if it seems equal, Sprint would be the better choice since you do not have any usage restrictions.

Now that we have picked a carrier, it is time to decide which card to get. This involves several steps depending on what you plan to use the card for.

If using the card only in your current laptop, then determine what kind of slot your computer has. There are 3 types of slots now in use.

1) PCMCIA or Type ll Card Slot.

This slot is the size of a Credit Card and has been around for over 5 years. Most older laptops have this slot. The advantage of using this type of card is that it keeps most of the card inside the laptop, with just about an inch of the card sticking out. You can install this card once and just leave it in the laptop. As these are going away and being replaced by the smaller express slots, it is probably best to go with one of the options below unless you know you will be staying with the same computer for a few years.

2) ExpressCard Slot.

This is the newer type of card slot that is about half the width of the PCMCIA card. Most of the newer laptops will have this slot. Once again, the advantage here is that most of the card is inside the computer and you can just leave it there without risk of it getting bumped or loosing it. ExpressCards vary in price from $0 to $150 with a new agreement.

3) USB Card Slot.

Every modern computer has a USB slot. This is the main advantage of a USB Card – it will work with a new or old laptop, and even desktop computers. If you have an older laptop with a PCMCIA slot, but know you will be upgrading laptops in the next 6-18 months, then get a USB card so that you won’t limit your selection of a new laptop. The one slight downside to a USB card is that most of it is external to the computer, making it a bit more to keep track of when transporting your laptop. USB cards are usually priced from $0 to $100 with a new agreement.

Other factors to consider:

Mobile Routers.

If you want to use a Mobile Router to share your connection, currently you will want to stick with either the PCMCIA cards like the Novatel S720, with the Kyocera KR2 router. Almost all the USB and Express Cards are compatible with the CradlePoint line of routers.

GPS Functionality.

To take advantage of some neat and free GPS functions like finding the nearest restaurant, gas station, mapping your location, and even real time traffic updates, go with a Sierra Wireless Card from Sprint. The Sprint Connection Manager for these cards allows you to use this service at no extra charge.
