Taiwan-based leader in smartphones HTC unveils its second full-QWERTY slider Android in the HTC Desire Z, a good 18 months after the first, the HTC Dream. Running the latest Android v2.2 Froyo, the new handset is powered by a Qualcomm MSM7230 engine clocked at 800 MHz. That’s a bit less muscled than the 1 GHz Snapdragon of the HTC Desire. From the aesthetics, it’s really a Desire that grew a QWERTY keyboard slider.

Great Flagship Features

Looking like the Desire when closed, the HTC Desire Z actually has the same the feature of the HTC Desire HD which is only distinguished by its larger 4.3-inch screen display. Instead you get a 3.7-inch capacitive S-LCD touchscreen with multitouch, WVGA (480 x 80) resolution, 16 million colors, accelerometer and proximity sensors.

Despite a set of flagship features, it is positioned as a more modest option than either the earlier Desire or its successor the Desire HD. It also boasts of social networking prowess that comes with Facebook, Twitter, Picasa, YouTube and Google talk integration.

The new HTC Desire Z is a cornucopia of data and telephony connectivity options. It’s 3G handset on the dual band UMTS/HSDPA/HSUPA and a quad band GSM on 2G with class 32 GPRS/EDGE data speeds. Local connectivity gets WiFi 802.11 b/g/n with DLNA, Bluetooth v2.1 with A2DP and microUSB v2.0 including GPS SatNav with A-GPS support.

Imaging gets a 5-megapixel autofocus camera with LED flash, face detection, geo tagging and video recording at 720p high definition while mobile entertainment gets the usual media playback features, a stereo FM radio with RDS and headphone listening in either wired (3.5mm jack) or wireless (A2DP) mode.

Internal memory gets 1.5 GB with 512 MB RAM and microSD expansion for up to 32GB. Its li-ion batters rated at 1300 mAh delivers up to 9.8 hours of call time on 2G, 6.6 hours on 3G with 430 hours on standby.

Wi-Fi stands for wireless fidelity. This technology was released in 1997 and is widely used around the world. The system uses the 802.11 standard which is a standard developed by the Institute of Electrical and Electronics Engineers.

Wi-Fi technology has common alternative spellings such as WiFi, Wifi, or wifi. The term Wi-Fi was initiated by a trade group that pushed for the commercialization of the internet technology. This trade group is the Wi-Fi alliance.

The purpose of Wi-Fi is to provide internet connection wirelessly with the use of wireless routers. Computers with Wi-Fi network cards can access the internet within the spectrum of a Wi-Fi network. The router connects to the internet with the help of a modem which is either cable or DSL. If the computer or device communicates with the router, internet access is achieved.

The estimated spectrum of a Wi-Fi access is 200 feet or 61 meters from the access point. However, it is suggested that a user remains within 100 feet or 30 meters to get good internet speed rates. Products are being manufactured and sold to users in the effort to boost the wireless signals of Wi-Fi networks to be able to extend its spectrum of coverage.

Wi-Fi networks can be open or closed. An open network provides internet access to anyone. A closed network requires a password so that a user can access the network.

The “wireless hotspot” refers to the area covered by the Wi-Fi wireless access. More cities are continuously making efforts in developing huge wireless hotspots as cities in themselves. San Francisco, Portland, and Philadelphia are some of the cities that have successfully made internet access widely available throughout the cities. Internet service can be given for free through the support of advertisements. Ad-free internet service is sometimes made available for a small internet fee.

The Wi-Fi technology uses radio communications with 2.4 GHz frequency. Wi-Fi certified electronics are guaranteed to communicate through the internet without having to be compatible in terms of brand. This internet technology is deliberately suitable for mobile and lightweight electronic devices that are designed to use nominal electrical power.

People require advanced technology that will allow them to remain mobile. The increasing popularity of mobile devices such as PDAs and laptops allow the Wi-Fi technology to reach its full potential matching the increasing mobility of the society.
