4G Americas, a wireless industry trade association representing the 3GPP family of technologies, has announced the publication of a technical report: “MIMO and Smart Antennas for Mobile Broadband Systems”, on progress with advanced antenna systems to provide a comprehensive solution for the growing data traffic over mobile networks.
“The wireless traffic in the United States nearly doubled over the past year and is expected to aggregate mobile data traffic worldwide which will grow between 11 and 13 times in the next five years,” said Chris Pearson, President of 4G Americas. “This puts pressure on the entire wireless industry to provide increased capacity and improved network performance. Many wireless carriers are facing this challenge by a variety of means, one no less has been rolling the deployment of smart antenna solutions with increasing capacity. ”
The 4G Americas white paper: MIMO and Smart Antennas for Mobile Broadband Systems, provides specific details of the techniques of Multiple Input Multiple Output (MIMO) antennas and configurations that have helped cover the burgeoning growth in demand for mobile broadband. The work focuses on the modes of transmission (TM, for its acronym in English) and the appropriate antenna configurations that have been tested in field deployments.
“The technology for base station antennas has been made in response to the requirements and trends of the industry,” said Stephen Wilkus, Director, Chief Technology Office Wireless Alcatel-Lucent and leader of the technical work group of 4G Americas white paper. “The main engines have been continuously adding frequency bands for cellular, integrating more functionality into a single shell in radomes, and antenna techniques to provide additional capacity for cellular networks.”
The 4G Americas report highlights the growing importance not only of smart antennas but the intelligent application of satellite technologies of all kinds, and highlights the important advances in the art of antenna technologies and associated signal processing. There will still be new optimizations as new technologies become standardized in 3GPP and operators and suppliers to collaborate to develop and implement antenna techniques with advanced technologies. MIMO and smart antennas have an important role in the ability of operators to increase their network performance with the commercial deployment of LTE (4G).
The LTE standard has made tremendous gains in the efficient use of MIMO and general smart antenna schemes, many of which have been increasingly applied to HSPA systems. LTE is unique in requiring that all terminals include a second receive antenna for receive diversity and downlink MIMO support.
