Multimode vector radio dismantles barriers to SDR software portability
My friends at Sigmatix and Octoscope have a nice follow-on EE Times article about Vector SDRs. The original article (mentioning Sandbridge) is here.
As an excerpt: To ensure the cost reduction of SDR platforms via economies of scale, software portability across processors must be achieved. The new generation of SDR, called multimode vector radio (MVR), offers that [...]
Network Performance – or when is a hub better than a switch?
Today is one of those crazy days where my network can not even seem to sustain a voip call. Frankly this really annoys me so I decided to debug my network. Recently I upgraded my home office to a business class cable modem with 5/22Mbps service. Simultaneously with that (yes, unadvised in any network deployment) [...]

Multimode wireless and SDR success lies in software optimization
I have a nice quote in a Mobile Handset DesignLine article written by Fanny Mlinarsky.
Shark Tank
Other than soccer I don’t watch much TV. Tonight though I caught the finale of Shark Tank. The Examiner gives a rundown. It was an interesting dynamic watching entrepreneurs and investors negotiate on TV. I couldn’t help but notice one even looks like fellow blogger (and original investor in my company) Mike Feinstein.
I’m not sure [...]
Crazy Entreprenuers?
The Kaufman Foundation published a 24 page report on the characteristics of entrepreneurs titles The Anatomy of an Entrepreneur: Family Background and Motivation. In it they profile the backgrounds, histories and beliefs of entrepreneurs. After a survey of 549 entrepreneurs from diverse industries including: aerospace and defense, computer and electronics, health care, and services, they [...]

Shameless plug…
The SDR Forum announced that Dr. John Glossner of Sandbridge Technologies has accepted an appointment as General Chair of the SDR ‘09 technical Conference and Product Exposition.
Morpheus Reconfigurable Processor Announced
The European Commission Information and Communication Technologies (ICT) announced The EU-funded MORPHEUS project, which includes big manufacturers of embedded systems such as Thales, Thomson, Alcatel-Lucent, STMicroelectronics and Intracom, is exploring a new approach.
Pressure is coming mainly from high-performance applications that need to process huge amounts of data in a short time. Examples include digital video [...]
Infineon Emerges with Satellite + Terrestrial SDR design win
Infineon announced that they are working with TerreStar on an SDR platform aimed at satellite-terrestrial handsets operating with multiple cellular and satellite-based communications technologies including GSM, GPRS, EDGE, WCDMA, HSDPA, HSUPA and GMR1-2G/3G. One year ago TerreStar announced the selection of [...]
Using software modems to enable low-cost, converged wireless
Chet Babla of Mirics Semiconductor has published a technical paper on multistandard Broadcast receivers implemented with a Mirics FlexiTV RF front end plus x86 processing for the baseband.
They implemented this on a 2.6GHz dual core x86 processor. Benchmarking standard definition (SD) DVB-T required 25% of the CPU load. The media player decoding of the SD [...]

Mobile World Congress (MWC): Observations from Barcelona
Last week the wireless industry met in Barcelona for the annual Mobile World Congress. I had the good fortune to attend the show and my company Sandbridge was an exhibitor.
The big announcement at the show was Nokia’s license to Broadcom of their modem IP. This legitimizes Broadcom’s cellular offerings on top of an already strong [...]
SDR Insider
John Glossner’s musings on Software Defined Radio (SDR), Digital Signal Processing (DSP), Wireless Communications, Computer Architecture, Programming, Technology, and Entrepreneurship
Commentary: Vista Rage
By John Glossner on June 18, 2009
I have finally begun the liberating experience of converting from Microsoft Windows-based installations to Linux. My final straw was constantly watching my CPU peg on an IBM X61s core duo 1.8GHz laptop with 4GB of physical memory. I can honestly say my user experience is worse on this machine than the 1983 IBM PC I [...]
