ECE Seminar - LTE MIMO Over the Air Test Methodologies
The Electrical and Computer Engineering department will be hosting a seminar featuring Istvan Szini from Antenna Innovation Research Lab, Motorola Mobility, Chicago. The topic of the seminar will be LTE MIMO Over the Air Test Methodologies
Abstract
The new technologies adopted for high data rate mobile devices communications; i.e. Long Term Evolution (LTE) and LTE-advanced, relies on Multiple-Input-Multiple-Output (MIMO) radio channel to increase capacity. MIMO physical layer has been rigorously investigated and it is a reality today in fourth generation (4G) of mobile devices. The deployment of commercially capable MIMO devices is largely motivated by the increased demand for smart-phones replacing feature phones. In spite of the large demand and consequently deployment of these devices, the certification process didn’t follow the industry needs, nowadays many cell-phone operators still defines MIMO compliance tests based on antenna figure of merit measured under uniform incoming power, and total isotropic sensitivity thus without the implementation of realistic spatial/temporal channel models.
This seminar content is based on work done in multiple MIMO OTA standard and research groups (CTIA MOSG, 3GPP RAN4 and COST IC1004 TWGO), supporting the definition of the upcoming MIMO over the air conformance test that meet the industry needs, presenting test methodologies that emulate channel environments with realistic spatial and temporal characteristics, as well as demonstrating that the behavior of different MIMO antenna systems under spatial channel models can’t be predicted while adopting isotropic channel models, neither can evaluate MIMO antenna design innovation.
Speaker Bio
Istvan Szini received bachelors degree in Electrical Engineering from Mogi das Cruzes University-Brazil in and Ph.D. from Aalborg University-Denmark. Currently, he's Distinguished Member of Technical Staff at Motorola Mobility Antenna Innovation Research Lab, at Chicago design center in USA. He's primary interests are related to research, innovation and design on electrically small antennas for mobile devices, antenna adaptive tuning systems, RF Front-end design and MIMO antenna systems. Prior to his research role, he was the antenna lead designer for dozens handsets antenna systems including the iconics StarTAC Tri-mode Dual-band, he lead the design of the first Motorola 3G handset with internal autonomous GPS antenna (A920/925), the first Motorola 3G Smartphone with four internal antennas (A/M1000), and the first handset with aluminum extruded housing (Devour/2009). Nowadays he's involved with 4G smartphones LTE MIMO antenna system design, Over The Air MIMO measurements, 5G mm wave and LTE Carrier Aggregation antenna systems enablers, he's Motorola delegate to MIMO OTA groups in CTIA, 3GPP RAN4, and COST IC1004 with liaison to CTIA. He has 11 peer-reviewed publications in the area of mobile devices antennas and holds 24 granted and pending patents.
