The past decade has seen an explosion of creativity and progress
in radio astronomy telescopes and techniques. In the coming
decade, we will harvest the fruit of these innovations with a
powerful new generation of radio telescopes that are coming on
line. These will open avenues for new science, in areas such as
the epoch of reionization, synoptic surveys for radio
transients, and exquisitely sensitive observations of the most
distant objects in the Universe. Dramatic improvements in
digital instrumentation have been and will continue to be
central to the advancement of the field. But there has also been
a resurgence of interest in many other areas including receiver
technologies, antennas, optimized array configurations, remote
site management, software, commensal observing modes, and
algorithms. Considerable attention has been paid to
manufacturability and array costs in order to address the
prospects of optimizing array performance at costs exceeding
$1B. Telescope projects have also bifurcated into genera
