Antiope Associates's CTO, Gregory Wright, spoke about our experience using the Haskell programming language at the Commercial Users of Functional Programming (CUFP) meeting in September 2008.
His talk, From Functions to Junctions: Ultra Low Power Chip Design with Some Help form Haskell, describes how we use advanced functional programming techniques to deliver state-of-the-art communication systems to our customers.

Radio Frequency Identification (RFID) is key to automating many logistical processes. Antiope Associates has expertise in all aspects of RFID, from circuit design and radio propagation to system level integration.
In September 2008 we did a high level survey of the radio frequency identification market for the New Jersey Technology Council RFID Work Group. The slides below introduced a roundtable discussion of business opportunities and challenges in RFID:

Electronic Price Labels are one of the most successful RFID products in the market today.
Antiope Associates' Gregory Wright was extensively involved with the design of the leading electronic pricing system on the market. He describes the difficult process of bringing an innovative product from concept to realization in:

Some of our work involves the rapid prototyping of communications systems. Our CTO initiated the Berkeley Emulation Engine (BEE) project, a large field programmable gate array (FPGA) system for testing new radio design ideas quickly.
The BEE connects to real radio hardware, allowing signal processing algorithms and hardware to be tested in an actual radio communication environment. Simulations are frequently over-simplified, and systems designed on the basis of software-only simulations often require extensive in-the-field debugging or fail to realize their design goals entirely.

Radio propagation inside buildings and other structures (e.g., ships, aircraft) is a specialized field in which Antiope Associates has considerable experience.
The presentation below discusses the indoor radio channel, the difficulties it presents and the how some of those difficulties can be turned to our advantage.
Since the presentation was first given, CMOS and SiGe chips have made inexpensive radios for the 5 GHz Industry-Science-Medical (ISM) band possible and systems using the faster 802.11a/g standards have been widely deployed. The core design information remains current and relevant.

Antiope Associates' Gregory Wright has recently worked on the fundamentals of energy efficient communication. This has led to a re-thinking of the best way to send information over very long distances.
A short version of this work appeared as a letter to the journal Nature and was featured on the cover of the 2 September 2004 issue.
A longer version was presented at the 38th Asilomar Conference on Signals, Systems and Computers in November 2004.

Antiope Associates' CTO has contributed to improvements in radio systems operating at submillimeter wavelengths: frequencies thousands of times higher than conventional cellular telephones or television broadcasts.
In an article that appeared in the Optical Society of America's Optics and Photonics News, he describes what we can learn about the universe from submillimeter radiation and why it takes him to the very end of the earth.
