Intersil
manufactures a host of spread-spectrum
related ICs and chip sets, most notably
the well-known Prism I, Prism II, and
Prism 2.5 chip sets. They also offer a
number of evaluation/reference boards for
these and other wireless chips, as well
as numerous online application notes and
tech briefs.
Miniature
FHSS digital transceiver modules
operating in the 2.4 GHz license-free
band. No additional hardware or software
development required. RS232 or TTL serial
interface, up to 115.2 kbps data rate (or
882 kbps non-standard), up to 77
channels, 500 ft range indoors, 10,000 ft
line-of-sight.
The
EWM-900-FDTC is a complete 56-channel,
full duplex FM/FSK in a .83x1.22"
package. It supports voice and data
communications. It sells for less than
$30 in quantities of 1000.
The
Wi.232DTS module combines a
state-of-the-art low power RF transceiver
with a powerful multipoint to multipoint
protocol controller to form a transparent
wireless communication link capable of
replacing most wires in RS-232/422/485
applications. Has a link budget of 111 dB
and a 1600+ feet line-of-site range.
The
Wi.232FHSS-25 module combines a
state-of-the-art low power transceiver
with a powerful multipoint-to-multipoint
controller to form a complete frequency
hopping spread spectrum wireless
communication solution. With a simple
UART interface and a 111 dB link budget,
these modules are perfect for application
such as AMR, home controls, and
industrial controls.
Low-cost,
miniature FHSS digital transceiver module
operating in the 900 MHz license-free
band. The MicroHopper transmits data at
19.2 kbps with a range of 500 meters,
line-of-sight.
Long-range
FHSS digital transceiver module operating
in the 900 MHz license-free band. This
powerful 1 watt transceiver communicates
at distances of up to 40 kilometers (25
miles) line-of-sight, depending upon
antenna selection and the environment.
The Hopper transmits data at 56 kbps and
has a high tolerance to environmental
conditions and interference.
