Mobile solutions company Samsung has unveiled mobile WiMax and Long Term Evolution (LTE) systems, believed to be some of the strongest 4G technology contenders today.
The two technologies are similar in nature, as both work on a backbone of Orthogonal Frequency Division Multiple Access (OFDMA), Smart Antenna and Multiple Input Multiple Output (MIMO), to name a few.
Collaboration between groups of telecommunications associations to make a globally applicable 3G and 4G standard is a natural progression for Samsung.
Samsung`s first public debut of LTE includes a total solution from infrastructure equipment to devices. The company has developed its own access network and core network systems, which support multi-vendor interoperability.
"Our LTE solution is fully compliant with the latest 3GPP LTE Rel-8 standard. We are starting active discussion and trial tests are starting this year, and we envision our first commercial LTE service to be available in 2010," says Hyojong Lee, senior VP of Samsung`s telecom systems division.
The company has invested a substantial amount of money and marketing resources into developing 4G wireless systems over the last few years, adds Lee.
"As a result, we have been able to obtain the core technologies of 4G systems such as OFDMA, MIMO and provide world first mobile WiMax commercial services.
"We see increasing demand for data services, regardless whether indoors or outside, even on the move. With our end-to-end total solution for the 4G wireless system, we will continue to constantly try and improve solutions in the mobile broadband environment for notebooks, mobile Internet devices and smartphones, targeting a diversity of consumer demands," Lee notes.
Samsung mobile WiMax Ubicell, also known as Femtocell, is a small cellular base station that provides improvements in home wireless coverage and capacity, and has been designed with ease in mind.
The company also highlighted two new base stations for macro coverage. "The U-RAS Flexible is a separated type of `digital unit` and `radio unit`, and U-RAS Compact can be used as a common platform for Mobile WiMax (802.16e) and Mobile WiMax Evolution (802.16m)," Lee explains.
