Nov. 16, 2011 WCA What’s Hot

On Wednesday November 16, 2011 in Santa Clara at Silicon Valley Bank hosted the WCA12th Annual VC Panel “What’s Hot (and What’s Not) in Mobility.” Carrie Walsh of Silicon Valley Bank moderated panelists Juha Christensen of Progression Partners, Steve Goldberg of Venrock, Tae Hea Nahm of Storm Ventures, Rama Sekhar of Norwest Venture Partners and Eric Zimits of Granite Ventures. They discussed the current and possible future of mobile technology.

While Apple makes most of the profits, Android is selling more phones. The diversity of devices from phones to televisions is forcing developers to prepare content for whatever “end screen” it winds up on. Much of that content will be social games running over an LTE or 4G network. Beyond games, users will navigate down the street with voice directions from services like Apple’s Siri. Once at a store, they will be guided with Location Based Systems (LBS) and scan Quick Response (QR) codes on items and compare them with online prices. If the price is right, they will buy it with Near Field Communication (NFC) technology, avoiding bank debit card fees.

While reusing available spectrum in developed countries is a major problem, getting the rest of the world online is the bigger opportunity. Most will use prepaid services and have trouble charging their devices. Solve these problems and build market growth where none existed before.

Nov. 9, 2010 WCA Cognitive Radio Commercialization

On Tuesday November 9, 2010, in Santa Clara at Qualcomm, the WCA Cognitive Radio SIG presented “Commercial Status of Cognitive Radio and SDR Technologies.” Dr. Lloyd Nirenberg of Shannon Bayes Company moderated panelists Dr. Steve Goldberg of Venrock, Dr. Ahmad Bahai of National Semiconductor and Dr. Andrea Goldsmith of Stanford University.

Cognitive Radio (CR) and Software Defined Radio (SDR) were originally developed for military and public safety interoperability requirements. Commercial demand for more allocated spectrum now drives development using wireless standard solutions like 802.11n, LTE, WiMax, IMT-A that were originally developed for CR and SDR.

Dr. Steve Goldberg focused on what constrained the technology in the past and future demands. Investors need to focus improving entire network performance, with better reception.

Dr. Ahmad Bahai reviewed optimal statistical channel search and selection techniques to intelligent spectrum sharing. He went on to describe new architectures for software radio and mixed signal processing circuits. Current global mobile traffic will increase between thirty and forty times over the next five years, most of it in video. Solutions to meeting demand on heterogeneous networks are intelligent network topology, spectrum management and interference management.

Dr. Andrea Goldsmith surveyed the CR/SDR technologies and described the design and regulatory challenges behind them. She showed recent innovations in wireless technology that may provide breakthroughs in commercializing smart radios. Cognitive radio could allow frequencies to be reused without increasing interference by using cognitive overlays, compressed sensing and other techniques.
