Which WiFi Technology Will Work For You?Welcome back to our series on WiFi networks. First, we explained the difference between the two major types of WiFi. Then we explained how to get your wireless network... uh... wired up. Now we'll help you decide the right WiFi format for you.

Now that you know the differences between WiFi-G and WiFi-N, which WiFi will work for you? Well the answer to that question depends on what sort of wireless shenanigans you have planned. But it is the most important answer of all, because the wrong choice will lead to disappointing results.

Which WiFi Where?

The differences between the two flavors of WiFi discussed in Part 1 is about a bit more than speed. It is also about future proofing your investment. While WiFi-G is widespread and your existing laptop or tablet probably has the correct WiFi component, it is also old tech. That is why it is so widespread! If it were new tech then it wouldn’t be so widespread. Bummer, huh?

In addition to availability is WiFi-G’s limited bandwidth. As we noted in Part 1, WiFi-G has a maximum bandwidth of 54 megabits per second. On a good day. Whereas WiFi-N has maximum speeds of 300 megabits and above! Doesn’t six times the data transfer speed sound enticing? We thought that it might. Luckily WiFi-N equipment will also work on WiFi-G networks. So you’ve got the best of both worlds! But like WiFi-G, it has a drawback: availability.

Since WiFi-N is newer technology, you will not find as many WiFi-N routers at your local coffee shops and elsewhere. In addition you will find that only the most recent laptops and a few tablets have WiFi-N components already installed. If you are not fortunate enough to have such a unit, you will have to purchase a WiFi-N adapter. These units are available at most big box electronic stores and are sold by companies like Linksys and Belkin but do cost more than WiFi-G adapters.

Which WiFi Will Work?

When deciding which WiFi network type is right for you, you must consider the type of work you plan on doing. Does your work consist of test documents and the odd spreadsheet? Is tending your farm on Facebook the most intensive thing you do on your computer? If you have this sort of light workload, then WiFi-G is more than you can handle! Actually even if you have more technical duties WiFi-G will work, just not as quickly.

However, if your daily routine has you working with large video or audio files then WiFi-N is for you. Transfer rates of 300 megabits or greater per second can cut downloads from sites like Dropbox and personal servers to a fraction. You’ll find that your upload rates will be much faster on WiFi-N versus WiFi-G also. So when once you have that important presentation done, you can upload it and the accompanying videos with no problems!

Stay tuned as we finish up this series with the important discussion about securing your network!
