3G Mobile Phones


Techs & Specs

The 3G mobile phone network uses a different frequency band than its predecessors to deliver increased data transfer rates. The 3G network uses the 2100MHz frequency, while the existing 2G network operates at the 900MHz frequency band (GSM) and 800MHz (CDMA). This high-speed data capacity enables more content to be sent to and from mobile handsets through calls, messaging and Internet-based content. For example, 3G phones can be used for video phone calls, video message bank, Internet and e-mail, real-time interactive gaming and media streaming, such as news, weather and dedicated TV shows.

The original analogue network was the first-generation cellular mobile phone network which was operational in the 1980s when handsets resembled 'bricks' rather than the tiny, feature-packed devices they've become today. The next major development was the digital cellular mobile phone network that started to offer data as well as voice services and was considered the second-generation mobile network. The 2G network has a data rate of between 9.6Kbps and 14.4Kbps and the 2.5G network boosted rates to between 56Kbps and 144Kbps. The 3G network can deliver data rates up to 2.4Mbps although High-Speed Downlink Packet Access (HSDPA) is a 3G technology that allows for higher data transfer speeds. Current HSDPA in Australia now supports 1.8Mbps or 3.6Mbps in downlink. Speeds of up to 14.4Mbps and beyond are planned for the future. But the real future is 4G that will deliver data transfer rates of between 20 and 40Mbps, comparable with ADSL and cable Internet transfer speeds. However, the 4G network is only in development and is still some time away from trials and commercial release of services.

Mobile phone coverage

While everyone does a great job of describing all the extra features, etc of the phones and that is very helpful, no one seems to comment on the actual reception. I know that most reviewers are probably in the city so that may be why. But for those of us in the country we seriously don't care about the camera or the looks, etc very much. For us the priority is will it work in rural areas often on the fringes of the network. Really all we want is a phone that we can actually make and receive calls on. It would be great if that could be included.

STYLISTIC Q702

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

STYLISTIC Q572

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
