The Benefits of LTE for Mobile Video

LTE uses a MIMO (multiple input multiple output) system in order to achieve high throughput and spectral efficiency. It uses 2 × 2 (i.e., two transmit antennae at the base station and two receive antennae at the terminal side), 3 × 2 or 4 × 2 MIMO configurations for downlink. In addition, LTE supports MBMS (multimedia broadcast multicast services) either in single cell or multi-cell mode. So far the adoption of LTE has been quite successful, as most carriers supporting GSM or HSPA networks (for example, AT&T, T-Mobile, Vodafone etc) have been upgrading their systems to LTE and a few others (for example, Verizon, China Telecom/Unicom, KDDI, and NTT DOCOMO, etc) that use different standards are also upgrading to LTE.

Mobile WiMAX is a part of the Worldwide Interoperability for Microwave Access (WiMAX) technology, and is a broadband wireless solution that enables the convergence of mobile and fixed broadband networks through a common wide area broadband radio access technology and flexible network architecture. In Mobile WiMAX, a scalable channel bandwidth from 1.25 to 20MHz is supported by scalable OFDMA. WiMAX supports a peak downlink data rate of up to 63M bps and a peak uplink data rate of up to 28Mbps in the 10MHz channel with MIMO antenna techniques and flexible sub channelization schemes.
