iPad 3G Vs WiFi: Review on Both the Models

So, I agree. You may not be a sloth, and do move out of your house. You go to public places that have free Wi-Fi for your convenience with no security hassles of Wi-Fi Protected Access (WPA) technology. You sit in a restaurant, drink coffee, and start savoring the free Wi-Fi connectivity that the restaurant provides you with. But what would you do when you’re done with your coffee? You don’t want to disconnect, and so, you order another one. Bah! Public WiFi is becoming all the more common. However, it is not available everywhere. If you’re a diligent stock broker, working 24×7 on the Internet, you wouldn’t want to go for an iPad with WiFi connectivity. The one with 3G makes more sense in that case, doesn’t it?

But obviously, you cannot have WiFi range wherever you go. You’d be able to enjoy free Internet access only in places that have a Wi-Fi connectivity. On the other hand, if you’ve picked up an iPad with 3G connectivity, no matter what area of the town you’re in, unless and until your 3G plan is valid and you’ve full access to the network, the world of Internet is in your palm. 3G signals follow you even while you’re traveling in cars or trains. However, they go away when you move beyond your city (depends upon what kind of 3G plan you’ve taken). But tell me, doesn’t 3G have an edge over WiFi?

It isn’t possible to talk about wireless Internet access and not mention speed. But here, I’d like to mention that, though the iPad with WiFi is always faster, iPad with 3G connectivity offers you equally fast Internet access at many instances. Not only does it depend upon the plan you opt for, but it also depends upon the area of efficiency of your device. Okay, WiFi is faster. Period. But then, we revert to the question yet again – till where?

Last but not the least, cost of the iPad 3G is a bit more than that of the iPad with WiFi. As mentioned above, the cost of the iPad 3G is $130 more than the one with WiFi. Simply put, where iPad 3G price range lies between $629 – $829, the WiFi iPad cost lies between $499 – $699 (the upper limit depicts the additional internal memory storage). But naturally, when 3G is a costly service, price range of iPad had to exceed. In addition, while it might not cost you at all to access WiFi at public places, 3G connectivity requires a particular plan to be activated on your iPad, monthly or yearly, so that you can access it without any disruption.

The bottom line of the iPad 3G vs WiFi comparison here is, if you’re a hardcore businessman with work solely dedicated to the Internet, you might not find a device better than the Apple iPad 3G, for it is only after you use it for a while that you’d be able to figure out exactly what is 3G network capable of. Even if you’re tech-savvy with piles of money in your account, this device doesn’t fail to entice you. However, if your budget is low, and you access the Internet for no more than updating Facebook and Twitter statuses, iPad with WiFi will do the trick for you, and you need not pick up the iPad 3G. But you know, $130 isn’t so big an amount to gain some smugness, and your friends’ envy, or is it?

The WiFi signal is a radio wave, which gets weaker with increasing distance of travel. The wireless router is the transreceiver, that is the source of the Wifi signal and your laptop’s wireless adapter is its receiver. The reception of the WiFi signal is therefore dependent on the initial output power at the router’s end and the distance between the router and the adapter. Let us see how to boost your laptop WiFi signal by tweaking certain settings and adding some new equipment.

How to Boost WiFi Signal on Laptop Computers?

I faced a problem with my wireless network some years ago as despite of a high bandwidth and state of the art router installed, I used to receive a very weak signal on my laptop. I decided to look into the problem and study ways in which the WiFi signal can be boosted. With some modifications that I learned about through my research, I was able to boost the WiFi signal beyond its existing limits. Whatever I learned about how to boost WiFi signal for laptop, I share in the following lines.

Upgrade Router Firmware
One of the first things that you need to do is check to see if your wireless router’s firmware is the latest one. If you find that it’s outdated, get the latest version Updating the router firmware can take care of some of the software issues that can bring down strength of the WiFi signal. For boosting WiFi signal for laptop, make sure that you install the latest driver for your wireless adapter.

Increase WiFi Router Output Power
One way of boosting the WiFi signal is increasing the output power of the wireless router. Refer to the router manual to determine the procedure for increasing the power output of the router. When the power of router’s output signal is enhanced, the WiFi signal reception on your laptop will automatically improve. If you ask me how to boost WiFi signal on laptop, most economically, increasing router output power is the best choice.

Use a WiFi Signal Booster Antenna
You can install a WiFi signal receiver booster antenna to the laptop, which will certainly improve the signal reception and your download speed will certainly be boosted. Check out antennas which offer a high gain and reduced noise levels.

Change Position of Wireless Router
Simply changing the position of your wireless router can boost the WiFi signal reception of your laptop. Physical constraints like walls can damp out the WiFi signal. So position it in such way that the signal is least obstructed by such physical barriers. A change in installed position will certainly boost the WiFi signal strength.

Use a WiFi Signal Repeater
If you need the WiFi signal to be receivable over large distances, you need to have a WiFi signal repeater installed. These devices receive the original signal from the router, amplify its strength and then retransmit it over longer distances. Use of long range wifi repeaters will certainly help in improving WiFi reception.

Attach a WiFi Range Extender Antenna to the Router
Another simple way of enhancing reception of your router is by attaching a WiFi signal booster. Once you attach an external wireless signal booster, the coverage range of the router will certainly increase, providing better wireless Internet access. Signals boosters for WiFi are available in all the major electronics stores.

Buy a New Router
WiFi antennas and signal boosters can substantially increase the range of your wireless network. The last option of course is to buy the best wireless router (2011), which provides greater signal strength and high transmission speeds. As wireless router reviews (2011) will reveal, the latest 802.11n based routers offer dual band transmission and transmission speeds in excess of 450 Mbps, which can certainly boost your laptop’s WiFi reception.

Hope these tips on how to boost WiFi signal on laptop computers help you improve your wireless Internet access experience. If you use a home wireless networking system, I suggest that you go for the best 802.11n router, which will not only provide you with longer range, but it will also enhance the data transmission speeds over the network. Make sure that you follow all the steps to secure a wireless network, as enhanced range makes your network vulnerable to external hacking attacks.
