Hardware differences between WiFi Galaxy Tab and Galaxy Tab 3G
Weaker GPU – One obvious difference that affects performance would be the weaker GPU, which basically means that video playback and gaming will be taking a huge hit. The lack of HDMI output also doesn’t help.
Fast CPU – In order to compensate for the WiFi Galaxy Tab’s weaker GPU Samsung has bumped to speed to 1.2 Ghz from 1.0 Ghz so the devices feel pretty fast and snappy when navigating it on the home screen.
Downgraded Bluetooth – Samsung also downgraded the Bluetooth; the 3G version supports Bluetooth 3.0 but the Wifi version only supports Bluetooth 2.1.
How to connect WiFi Galaxy Tab to 3G network
Apart from the obvious difference price and the hardware, the lack of 3G should be the biggest difference between Wifi version and 3G version.
But this is not the hardest problem for the moment as mobile WiFi hotspot becomes more and more popular. The mobile hotspot is actually a mini router which can convert 3G to WiFi signal and share with 5 people at least, and as it is very small, just the size of a cell phone, so you can take it wherever you go. Someone may say that many Smartphone already have the personal hotspot feature. That’s true, but there are two important disadvantage of the cell phone personal hotspot: Speed and users amount. Let’s take iPhone 4 for example, the fastest mobile hotspot by now is up to 21 Mbps download speed, but as far as I know, iPhone 4 can only supports 3 users with up to 2Mbps speed.
So, if you already had a cell phone personal hotspot, is it still worth it to get a mobile WiFi hotspot for Galaxy Tab? Depends on your needs I guess. If you’re getting it to just surf the web and check emails and do the occasional YouTube video then it definitely isn’t worth it but if you want to play online games, watch online HD quality movies or make video call, just get the high speed mobile hotspot. Paying extra $100-200 for it is definitely worth it. Not only Samsung Galaxy Tab, but for other Tablets the mobile hotspot would be a good partner.
