• Lead Access Point software development engineer on time-based solutions to facilitate low-latency indoor, Wi-Fi client location {2 US patents}
• Access Point software team’s lead representative at the Wi-Fi Alliance (WFA) contributing to industry circulated Marketing Requirements Documents and Wi-Fi handset/infrastructure interoperability decisions on Network Power Save (802.11v, 802.11k features), Wireless Network Management (802.11k) and Multiband Operations. Involves closely working with product managers and strategic initiatives/CTO office for feature selection and Cisco Access Point interoperability with handset and chipset vendors
• Test engineering for WFA interoperability testing at WFA Santa Clara Labs for Network Power Save (802.11v) features for plugfests and certification•Developed software to facilitate dual-band scanning and monitoring of the RF environment foran external dedicated scanning radio module used for Cisco Enterprise WLAN products (3600 series Access Point and WLAN controller). Software will allow for non-Wi-Fi interfering device identification and measuring characteristics such as noise, interference and general air quality

• Leading development of a Markov-based analytical model to evaluate performance metrics in a cellular load balancing system. This work has been extended to include a combined analysis of Opportunistic Spectrum Access procedures with cellular load balancing
• . Contributed in creating a dynamic simulation environment to model and evaluate the network per- formance of femtocells in WCDMA/HSPA networks
• . Characterized interfering transmitters with the use of spectrum sensing techniques and RF finger- printing
• . Helped develop a probabilistic approach to determine the number of frequency hopping interferers in a specific band of interest for spectrum
• . Developed a Markov model to assess the performance differences between adaptive and non-adaptive channel bonding in orthogonal access schemes
• Areas of interest include: spectrum sensing, digital speech processing, digital image processing, RF fingerprinting, load balancing, modeling and simulation of wireless networks
