Click On The Image To See The Bigger Size















Finally  the clash of the Titans is here once again. Last Thursday saw the release of the Samsung Droid Charge and the white-colored iPhone 4.

The Samsung Droid Charge is the second-LTE enabled smartphone of Verizon Wireless, packed with 1 GHz single core processor, 8 megapixel camera for shooting HD videos and capturing quality still shots, and supports mobile hot spots  of up to 10 WiFi enabled devices.

Meanwhile, the white iPhone 4 is the latest product of Apple available via AT&T and Verizon. The new iPhone 4′s specs is the same as the black iPhone 4, so the only difference is the packaging of the device.

This specs sheet, from Popherald will help you to  quickly  compare  the two devices. One of the biggest advantages of the Samsung Droid Charge is the LTE support. Apparently, the Long Term Evolution is faster (way faster) than the regular 3G CDMA speed. Design-wise its always the Apple way , the  iPhone 4 is like all apple devices designed much better.

3GPP Long Term Evolution (LTE), is the latest standard in the mobile network technology tree that produced the GSM/EDGE and UMTS/HSPA network technologies. It is a project of the 3rd Generation Partnership Project (3GPP), operating under a name trademarked by one of the associations within the partnership, the European Telecommunications Standards Institute

MetroPCS, Verizon Wireless and AT&T Mobility in the United States and several worldwide carriers announced plans, beginning in 2009, to convert their networks to LTE. The world's first publicly available LTE-service was opened by TeliaSonera in the two Scandinavian capitals Stockholm and Oslo on the 14th of December 2009.

The LTE specification provides downlink peak rates of at least 100 Mbps, an uplink of at least 50 Mbps and RAN round-trip times of less than 10 ms. LTE supports scalable carrier bandwidths, from 1.4 MHz to 20 MHz and supports both frequency division duplexing (FDD) and time division duplexing (TDD).

Verizon Wireless announced their expansion into the 4G Long Term Evolution (LTE) realm. It’s an important move since competitors such as Sprint have already taken the first steps into their own WiMax-based 4G network, which is now available in nearly 50 market markets. Lowell McAdam, CEO of Verizon Wireless, announced that 38 metropolitan areas will cover nearly 110 million Americans by the end of this year. The company’s 4G LTE networks will also extend to over 60 airports across the country.

Part of the LTE standard is the System Architecture Evolution, a flat IP-based network architecture designed to replace the GPRS Core Network and ensure support for, and mobility between, some legacy or non-3GPP systems, for example GPRS and WiMax respectively.The LTE standard can be used with many different frequency bands. There are planned 700 MHz deployments in North America (Verizon); 900, 1800, 2600 MHz in Europe; 1800 and 2600 MHz in Asia; 1800 MHz in Australia.
