The Universal Handset

Suppose you set up a transmitter with a single antenna and then move a receiver, also with a single antenna, far enough away for the reception to fade in and out once in a while. Such problems arise because the transmitted signal takes multiple routes to the receiver—some of it perhaps bouncing off a passing car, other parts reflecting off the steel beams of the building where the receiver is located.

Winner: Radio Revolutionaries

Software-defined radio is one of those promising but elusive ideas that’s been anticipated for quite some time. The concept is elegantly simple: get rid of the specialized electronics used to process radio signals and instead do everything with software. The result, we’ve been promised, will be a universal wireless device that can seamlessly handle a range of frequencies, modulation techniques, and encoding schemes. Just as the personal computer replaced the typewriter, the adding machine, and even the telephone, so too will a software radio one day replace your cellphone, Blackberry, and any other wireless device you may happen to use. A cellphone based on software-defined radio would be lighter, smaller, cheaper, and more power efficient. We aren’t there yet, but software-defined radio is definitely coming.

USB in a NutShell - Chapter 1 - Introduction

With the USB 2.0 specification at 650 pages one could easily be put off just by the sheer size of the standard. This is only the beginning of a long list of associated standards for USB. There are USB Class Standards such as the HID Class Specification which details the common operation of devices (keyboards, mice etc) falling under the HID (Human Interface Devices) Class - only another 97 pages. If you are designing a USB Host, then you have three Host Controller Interface Standards to choose from. None of these are detailed in the USB 2.0 Spec. The good news is you don’t even need to bother reading the entire USB standard. So now we can begin to read the parts of the standard relevant to our needs. 4 - Architectural Overview 5 - USB Data Flow Model 9 - USB Device Frame Work, and 10 - USB Host Hardware and Software.
