A fourth-generation MIMO-OFDM broadband wireless system: design, performance, and field trial results

TLDR

High‑performance 4G broadband wireless relies on multiple antennas at both base station and subscriber ends, enabling high capacities for Internet and multimedia services while dramatically increasing range and reliability. The article describes a MIMO‑OFDM wireless communication system and presents lab and field test results from San Jose, California. The system is a MIMO‑OFDM wireless communication architecture evaluated through lab and field tests in San Jose, California. The field tests are the first to establish MIMO performance, showing clear increases in capacity, coverage, and reliability.

Abstract

Increasing demand for high-performance 4G broadband wireless is enabled by the use of multiple antennas at both base station and subscriber ends. Multiple antenna technologies enable high capacities suited for Internet and multimedia services, and also dramatically increase range and reliability. In this article we describe a multiple-input multiple-output OFDM wireless communication system, lab test results, and field test results obtained in San Jose, California. These are the first MIMO system field tests to establish the performance of MIMO communication systems. Increased capacity, coverage, and reliability are clearly evident from the test results presented in this article.
