2. General
2.0 Product Overview
The nMIMO2458 is a high-performance embedded wireless data
transceiver. Operating in the 2400 – 2483.5 MHz or 5725 – 5875 MHz
ISM bands (selectable), this spread-spectrum module is capable of
providing reliable wireless data transfer between almost any type of
equipment. The small-size and superior RF performance of this module
make it ideal for many applications.
While a pair of nMIMO2458 modules can link two terminal devices
(“point-to-point” operation); multiple modules can be used together to
create a network of various topologies, including “point-to-multipoint” and
“repeater” operation. Multiple independent networks can operate
concurrently, so it is possible for unrelated communications to take place in
the same or a nearby area without sacrificing privacy or reliability.
1.1 Features
Key features of the nMIMO2458 include:
 transmission within a public, license-exempt band(s) of the
radio spectrum

– this means that it can be used without access
fees (such as those incurred by cellular airtime).
 Up to 30dB transmit power in 2.4GHz mode, or up to 20dB in
5.8 GHz mode.
 a serial I/O data port with handshaking and hardware flow
control, allowing the nMIMO2458 to interface directly to any
equipment with an asynchronous serial interface.
 ease of installation and use – the nMIMO2458 module uses a
subset of standard AT style commands, very similar to those
used by traditional telephone line modems.
 all units in a system are physically identical, and can be
configured as a master, repeater or slave using the AT
command set. No hardware modifications are required
 128 sets of user-selectable pseudo-random hopping patterns,
intelligently designed to offer the possibility of separately
operating multiple networks while providing security,
reliability and high tolerance to interference.
 encryption key with 65536 user-selectable values to maximize
security and privacy of communications.
 32-bit of CRC error detection and auto re-transmit to provide
accuracy and reliability of data.

need to be factory-configured differently for some countries.
