RAMP MODULES
Laird Technologies RAMP (Range Amplified MultiPoint) modules are designed to provide
robust wireless communications for any number of applications requiring a wireless
transport for serial data. RAMP modules feature a Frequency Hopping Spread Spectrum
(FHSS) protocol for excellent interference and multipath immunity. RAMP modules
Server/Client architecture allows for more than 16 million clients to be addressed and
communicating within the network.
RM024
The RM024 RAMP module is based on Laird Technologies LT2510 core technology,
enhanced with a new RF front end for improved sleep, improved link budget and a
switchable antenna output. The RM024 is available in two versions, one with 125 mW
maximum conducted output power and approved for North American and similar
markets and one with 50 mW maximum conducted output power and approved for
European and similar markets. These modules are identical except for output power,
transmit power consumption, and the number of RF Channels available. Differences
between the two versions, where applicable, will be denoted based on part number.
Enhanced API commands provide packet routing control and network intelligence.
With its field-proven FHSS air interface protocol, the RM024 rejects RF noise, excels in
multipath scenarios, allows for co-located systems, and provides an extremely reliable
communication link. It also provides a more robust, but simpler, link than ZigBee for RF
applications that do not require a mesh topology.
With a throughput of up to 280 Kb/s, RM024 delivers speedy data rates. In addition,
variable output power options (up to +21 dBm) enable communication over distances
that arent achievable with competing technologies. At the same time, a range of
ultra-low power modes plus low Tx/Rx power consumption make the RM024 ideal for
power-restrictive or battery-operated applications. The mini SMT package is well-suited
for space-constrained designs and is available in pick-and-place packaging for volume
manufacturing.
