Overview
SRF 2400M is 20dBm Direct Sequence
Spread Spectrum (DSSS) wireless module that allows wireless communication
between systems using a standard UART protocol. SRF 2400M has novel
features as automatically reconfigurable network and the communication
architecture supports both direct or multi-hop message packet delivery
such that the protocol and messaging strategy supports random networktopologies.
Boasting
excellent sensitivity, networking extended range and highly robust
communication protocol against interference, SRF 2400M is perfect
for applications such as Supervisory Control and Data Acquisition
(SCADA), remote meter reading, home automation, security, instrument
monitoring, point of sale systems(POS), and countless other applications.
Multi Channel / Multi-Hop
SRF 2400M module is based on Carrier
Sense Multiple Access (CSMA) for multi channel communication and
the communication architecture supports both direct and multi-hop
message packet delivery. Multi-hop communication enables the communication
range to be extended even further. For instance, the range can be
increased three-fold using three nodes configured as a three-hop
network. SRF 2400M is especially useful in fields where cable installation
is costly or tedious.
Automatic Network
Configuration
SRF 2400M modules are dynamically
network configurable which greatly eases the installation procedure.
There is no need to go through strenuous network configuration procedures
as one would encounter setting up the I.P. address for connection
to the internet. The protocol and messaging strategy supports random
topologies.
Setting the local address of one
module to “1” makes the module the “master” or the “base station”
and all other additional modules with differently-assigned
addresses makes them “nodes”. When the network is configured,
sending a UART command to the base station, then all the other nodes
are automatically linked to the base station by both direct and
multi-hop connections. Then, the base station can communicate with
any node configured in the network.
Reliable
Data Transmission
20dBm
output power, -90dB sensitivity and robust handshaking protocol
makes SRF 2400M module a very reliable communication module.. IEEE802.11-
like Request-To-Send(RTS), Clear-To-Send(CTS) protocol alleviates
“Hidden node” problem, common in multi-hop networked communication.
Advanced Carrier-Sense protocol senses both inter-SRF 2400M carrier
and also other in-band high power RF signals such as signals from
WLAN, Bluetooth and microwave oven making it operate robustly in
the often highly congested 2.4GHz ISM band.
