By John McKeague In the beginning there was GSM. And then there was GPRS, and then UMTS/W-CDMA. In the future, hopefully not too distant future, there will be LTE. LTE (Long Term Evolution) is many things but an evolution of the current 3GPP technology it is not. If an egg-laying amphibian had given...

By Robert Best - Award Solutions Summary: The deployment of LTE networks will be a disruptive event in wireless network evolution, what we refer to as a Black Swan. Traditional backhaul solutions will need to be reconsidered. Though we have always had one way of handling wireless backhaul, LTE will dictate...

Executive summary Mobile broadband is becoming a reality, as the Internet generation grows accustomed to having broadband access wherever they go, and not just at home or in the office. Out of the estimated 1.8 billion people who will have broadband by 2012, some two-thirds will be mobile broadband consumers...

By Kim Tong-hyung Korea prides itself as a high-tech innovator, but a recent government report cautions that the country's superiority in technology is declining. The contention between WiMAX and LTE (Long Term Evolution) in the standards race for next-generation wireless networks, called ``fourth...

Will milk HSPA software enhancements, then jump to LTE T-Mobile barely has their third generation HSDPA network up and running, something highlighted by the recent launch of the HTC G1 with Android. Given they're so late to the 3G game (not their words of course), T-Mobile tells Unstrung that the...

Click here for more information Free eLearning Demo Advanced multiple antenna technologies enable emerging 4G cellular technologies to achieve superior data rates over the air interface (e.g., in excess of 100 Mbps). While 4G networks utilize an efficient multiple access technique called OFDMA (Orthogonal...

This article discusses WiMAX and LTE: in particular, how to implement the core DSP algorithm of OFDMA, then the novelvariant used by LTE for the uplink, and finally a brief discussion on MIMO for both WiMAX and LTE. It describes these in the context of a software-defined flexible architecture.

Multiple Input Multiple Output is a multiple antenna technique where spatial multiplexing is used to increase data rates over the air, in proportion to the number of antennas used. In MIMO, multiple transmitting antennas will carry parallel bit streams thus creating multiple channels over the air. The...

Single Carrier FDMA or DFT-Spread OFDMA is the uplink transmission method in LTE. The main benefit of SC-FDMA in uplink is to reduce the high Peak to Average Power Ratio (PAPR) of the OFDM signal and this allows a cheaper and easier implementation in the mobile devices. The lower PAPR is achieved by...

Orthogonal Frequency Division Multiplexing is a multi-carrier technique used in LTE and other advanced wireless systems. In OFDM a high-rate bit stream is multiplexed into a number of narrow band subcarriers and transmitted in parallel on different subcarriers which do not interfere with any other subcarrier...
