 1 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 spectrum1 – 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.                                                         1 2400-2483.5 MHz or 5725 – 5875 MHz, which are license-free within North America; may need to be factory-configured differently for some countries.
2     TDMA (time division multiple access) support, allowing multi-slave access in point-to-point mode.  roaming ability, allowing repeaters and slaves to re-synchronize with a new master if the synchronization pulse from the original master is lost. While the typical application for the nMIMO2458 is to provide a short- to mid-range wireless communications link between DTEs, it can be adapted to almost any situation where an asynchronous serial interface is used and data intercommunication is required.  2.1 Output Power Level The  Output  Power  Level  determines  at  what  power  the  nMIMO2458 transmits.  The nMIMO2458’s sensitive receiver can operate with very low power levels, so it is recommended that the lowest power necessary is used; using excessive power contributes to unnecessary “RF pollution”. Ideally,  you  should  test  the  communications  performance  between  units starting  from  a  low  power  level  and  working  upward  until  the  RSSI  is sufficiently high and a reliable link is established.  The conditions will vary widely  between  applications,  the  output  power  settings  can  be  calculated based on following information.  Transmitter antenna gain   Cable loss  Equivalent Isotropically Radiated Power (EIRP)    Power Setting = 31.51 – Antenna Gain  – Cable Loss The power setting must be no more than the above calculation value.

Chapter3 Installation 3 3.  Installation        3.0 Overview The  nMIMO2458  complies  with  FCC  part  15  at  the  modular  level  for operation in the license-free 2400-2483.5 MHz or 5725 – 5875 MHz ISM bands.  This  chapter  provides  guidelines  for  installing  and  deploying equipment which incorporates the nMIMO2458 module. 3.1 Estimating the Gain Margin Successful communication between nMIMO2458 modules is dependent on three main factors:  System Gain  Path Loss  Interference System  gain  is  a  calculation  in  dB  describing  the  performance  to  be expected between a transmitter-receiver pair.  The number can be calculated based on knowledge of the equipment being deployed.  The following four factors make up a system gain calculation: 1. Transmitter power (user selectable) 2. Transmitter gain (transmitting antenna gain minus cabling loss between the transmitting antenna and the nMIMO2458 module) 3. Receiver gain (Receiving antenna gain minus cabling loss between the receiving antenna and the module) 4. Receiver sensitivity (Specified as -108dBm on the nMIMO2458 module) In the following illustration, the transmitting antenna has a gain of  2 dB, and the receiving antenna has a gain of 2 dB.  The cable loss between the module and the antenna is 0.49 dB on both the transmitting and receiving side.         Transmitter 30 dBm Output Power Receiver Sensitivity = -108 dBm Cable Loss = 0.49 dB Cable Loss = 0.49 dB Antenna Gain = 2 dB Antenna Gain = 2 dB
4 nMIMO2458 Operating Manual Figure 1  Gain Calculation The power  level has been  set to 30dBm (1W) on the transmitter, and the receiver sensitivity for the nMIMO2458 is -108dBm.   System gain would be calculated to be: 30 – 0.49 + 2 + 2 – 0.49 + 108 = 141 dB.  Figure 2 System Deploying When deploying your system, care must be taken  to ensure the path loss (reduction  of  signal strength  from  transmitter  to receiver  in  dB) between equipment does not exceed the system gain (141 dB in the above example).  It is recommended to design for a gain margin of at least 20 dB to ensure reliable communication.  Gain margin is the difference between system gain and path loss.  Referring to the same example, suppose the path loss is 100 dB,  the  gain  margin  would  be  41  dB,  which  is  more  than  adequate  for reliable communication. Path loss  is a  very  complicated  calculation  which mainly  depends  on  the terrain profile, and the height of the antennas off the ground.  The following table provides path loss numbers for varying antenna heights and antenna separation:  These numbers are real averages taken from rural environments.  They do not apply to urban, non-line-of-sight environments. Table 2 Path Loss Distance (km) Base Height (m) Mobile Height (m) Path Loss (dB) 5 15 2.5 116.5 5 30 2.5 110.9 8 15 2.5 124.1 8 15 5 117.7 8 15 10 105 16 15 2.5 135.3 16 15 5 128.9 16 15 10 116.2 16 30 10 109.6 16 30 5 122.4 16 30 2.5 128.8  Base Height (m) Mobile Height (m) Distance (km)
nMIMO2458 Operating Manual 5       Once the equipment is deployed, you can verify the signal strength by entering into Command Mode and reading Register S123.  This register provides the average signal strength in dBm.  The minimum strength for communication is roughly -108dBm.  For consistent reliable communication, you should try to deploy the equipment such that signal strength exceeds -90dBm.  3.2 Antennas and Cabling This  section  describes  the  recommended  procedure  for  installing  cabling and antennas for use with the nMIMO2458 module. 3.2.1 Internal Cabling The most common method for installing the module is to run a cable from the module’s UFL connector to a reverse TNC bulkhead connector on the chassis of the equipment as shown in Figure 3.  This cable can be purchased from Microhard Systems.    Figure 3 Suggested Internal Cabling   Cable  losses  are  negligible  for  the  short  piece  used  within  the  chassis.  Additional losses up to 0.5 dB may be present in the UFL and Reverse TNC connections.

6 nMIMO2458 Operating Manual   WARNING: MAXIMUM EIRP Up to 31.51 dBm effective isotropically radiated power (EIRP) in 2.4 GHz Band.  Therefore, the sum of the transmitted power (in dBm), the cabling loss and the antenna gain cannot exceed 31.51 dBm with respect to the isotropic radiator.     WARNING: The nMIMO2458 can only be used with any antennas listed in Appendix A.   WARNING: Be careful with dBi vs dBd gains on antenna specifications.  Antenna manufactures may not clearly indicate the gain on the antenna if it is dBd or dBi. Note 1dBd = 2.15dBi.3.2.2  Antennas  Direct human contact with the antenna is potentially unhealthy when the nMIMO2458 is generating RF energy. Always ensure that the nMIMO2458 equipment is powered down during installation. At all times a distance of 23 cm (33cm for Industry Canada) must be maintained between the antenna and any person when the device is in operation. Antenna Type The nMIMO2458 is tested and approved to be used with a Rubber Ducky, Omni-directional antenna which is suitable for applications where there are multiple  units  that  you  must communicate  with,  or  with  units that are  in motion. Antenna Type Note (Rubber Ducky):  Maximum Gain of 2dBi for 2.4GHz Band with a minimum cable loss of 0.49, the antenna assembly gain shall not exceed (2 – 0.49) dBi.  Maximum Gain of 3dBi for 5.8GHz Band with a minimum cable loss of 1.02, the antenna assembly gain shall not exceed (3 –1.02) dBi. Microhard Systems Inc. can provide you with approved antennas to ensure FCC and Industry Canada compliance. The nMIMO2458 (2.4 GHz Band) has a maximum of 31.51 dBm effective isotropically radiated power (EIRP).   EIRP is calculated as follows: EIRP = Tx Power(dBm) - Cable/Connector Loss(dB) + Ant Gain(dBi) Antenna Gains must be in dBi when calculating the EIRP limit.  1dBd = 2.15dBi Use the guidelines in the previous section for calculating cable and connector losses.  If cabling and connector losses are 2 dB, then the maximum allowable gain of the antenna will be 2 dB.     Maximum Antenna, Power and EIRP values for  nMIMO2458   Band Antenna (Rubber Ducky) Power Level Minimum Cable / Loss EIRP 2.4 GHz 2 dBi 30dBm 0.49dBi 31.51dBm 5.8 GHz 3 dBi 24.33dBm 1.02dBi 26.31dBm
