Wireless Communications Expert Consultant Resume

This expert has experience in wireless communications, measurement and simulation of spatial mobile radio channels, spatial channels (including MIMO), and ultra wideband propagation channels. This consultant is also knowledgeable of smart antennas in mobile communications, MIMO systems, and ultra wideband systems.

This expert has investigated, both theoretically and experimentally, the fundamentals of wireless communications, and their impact on system design. This expert is contributing to breakthrough technologies for enabling high-speed wireless communications for next-generation cellular systems and wireless computer networks, such as multiple-antenna (MIMO) and ultra wideband (UWB) technologies, and wireless sensor networks. This expert's work experience also includes the using of cross-layer techniques to enable energy-saving, low-latency, and ultra-reliable sensor networks, as well as UWB-based sensor networks.

This consultant is recognized as one of the world’s leading authorities (as evidenced by awards, invitations for plenary speeches at major international conferences, etc.) for the following topics:

Wireless propagation channels: As new wireless technologies are developed and deployed, it is vital to understand and model the properties of the wireless propagation channel that are relevant for those channels. The well-known conventional channel models (Rayleigh fading, Hata pathloss model) are therefore not sufficient for designing, analyzing, and deploying modern broadband systems. This consultant has contributed a large part of the key measurement results and fundamental modeling techniques for propagation channels for wireless broadband systems. This consultant developed the generic models for multiple-antenna and ultra wideband channels, models that are now used by the majority of academia as well as industry. This expert also was the first one to measure many important effects in such propagation channels. This consultant has been a key contributor to the majority of internationally standardized channel models developed in the last 10 years, namely the 3GPP Spatial Channel Model, the COST 259 Directional Channel Model, the COST 273 MIMO channel model, the IEEE 802.15.3a UWB model, and the 802.15.4a UWB model.

Ultra wideband transmission is a physical-layer communication technique that has received enormous interest and is one of the most rapidly growing areas of wireless communications. It allows extremely high data rates, robust data transmission with small power consumption, and precise geolocation of nodes. It is thus of great importance for both high-speed wireless communications and sensor networks. This expert made key contributions to the field of UWB both on the theoretical side, and the development of industrial UWB systems at Mitsubishi Electric as well as international standards organizations. This expert invented original transmitter/receiver structures that reduce cost and energy consumption, and have been accepted as industry-wide standards. Prototypes developed demonstrate the feasibility of the concepts developed.

Multiple-antenna (MIMO) systems are the best and most efficient way to providing the high data rates and high spectral efficiencies that are required for next-generation cellular systems and wireless internet. Two particular examples of this consultant's contributions in this area are reducing costs through antenna selection. Antenna selection employs a large number of (cheap) antenna elements, and only a few (expensive) RF chains, which are dynamically connected to the best antenna elements. This consultant's work laid the theoretical foundations, and also explored many implementation aspects that are necessary to make it practical. Antenna selection has become very popular and was accepted into numerous international standards. Secondly, this consultant was involved in improving spectral efficiency and robustness through cooperation between base stations. Such cooperation has especially beneficial effects on devices near the cell edge, the traditional "Achilles heel" of cellular systems. This expert originally introduced this technique at AT&T Bell Labs, and made further theoretical contributions later on, including ongoing proposals to several fourth-generation cellular system standards.

Wireless sensor networks (including ad-hoc networks and cooperative communications systems) are the most recent of this consultant's research topics. Wireless sensor networks currently draw a lot of attention from the research and business communities, because they improve reliability, reduce power consumption, and allow new types of applications. While traditional sensor networks simply forward information from one node to the next along a route, this expert's research concentrates on more advanced, cooperative, methods for relaying information.

Standards and Practical Systems

This expert has been contributing to a number of international standards both for broadband wireless communications, and for sensor networks. Work has encompassed the following tasks:

Development of new technologies: generation of new ideas, validation by simulation and prototype

Applications of new technologies in products: analysis of new applications, advantages with respect to competing products,..

Patenting: cooperation with patent lawyers in writing patent bodies, claims, etc., with particular attention to future enforceability

Contributing ideas to standardization: explaining fundamental ideas to standardization bodies, drafting of standards submissions, including text that could be directly included in the final standard

Strategic/political negotiations with other companies: harmonization of standards proposals, establishment of alliances to further our ideas and patents, etc.

Leadership role in standards organizations: acting as leader of various standards groups

This expert has contributed to, and is knowledgeable about, the following:

3GPP LTE (Long-Term Evolution): this fourth-generation cellular standard will be the dominant wireless standard when it is deployed starting approximately 2010. It is supported by all the major carriers in the US (with the possible exception of Sprint), Europe, and Japan. It will provide data rates in excess of 100 Mbit/s, thus greatly exceeding the performance of the current 3G high-speed services. This consultant has worked on various aspects of the physical layer, in particular MIMO-OFDM, of this standard. Antenna selection technology and pilot tone designs developed were accepted into the standard.

Advanced Wimax (IEEE 802.16m): this standard is an evolution of the Wimax standard that is promoted by Intel and several major operators for wide-area computer networks. In contrast to WiFi, which allows laptops to access the internet in hotspots only, Wimax allows access anywhere in a city or even the whole nation. "Mobile Wimax" is currently being deployed; "Advanced Wimax" will provide significantly higher data rate and higher robustness. This expert has been involved in the development of the standard since its inception, and has contributed in many areas ranging from base station cooperation to relaying to antenna selection.

High-throughput WiFi (IEEE 802.11n): the evolution of the popular WiFi standard, 802.11n offers significantly higher data rates (up to 10 times faster) through the use of multiple antenna technology. The standard is currently being finalized, and a number of products based on preliminary versions of the standard are already on the market. It can be anticipated that within the next 2 years, all high-end laptops will have 802.11n built in. This expert was involved in the development of the standard from the beginning (lead author of one of the partial baseline proposals), and several technologies developed (training for antenna selection; certain aspects of adaptive modulation for MIMO) were included in the standard.

Low-rate ultra-wideband Personal Area Networks (IEEE 802.15.4a): the 802.15.4a standard provides efficient low-data-rate communications and high-precision ranging and geolocation for sensor networks. It is based on ultra wideband impulse radio technology, and serves as a significant improvement to the popular 802.15.4 (Zigbee) standard. This expert was the lead author of the accepted baseline proposal, and is responsible for the majority of the technology included in the standard developed.
