SIMREX MAN.ESS-01, Rev. F

SIMREX Corporation

NOTE:

While the transceiver accepts RTS Threshold values below
100, the lowest value that works is 100.

TIP:

Lower the 

RTS Threshold

 as the number of Remotes or 

overall over-the-air traffic increases. Using RTS/CTS is a 
trade-off, giving up some throughput in order to prevent 
collisions in a busy over-the-air network.

The 

RTS Threshold

 should be enabled and set with a value 

smaller than the 

Fragmentation Threshold

 described above. 

RTS forces the Remotes to request permission from the 
AP before sending a packet. The AP sends a CTS control 
packet to grant permission to one Remote. All other 
Remotes wait for the specified amount of time before 
transmitting.

•

RSSI Threshold (for alarm)

—Level (dBm) below which the 

received signal strength is deemed to have degraded, and a crit-
ical event (alarm) is generated and logged. Under these condi-
tions, the 

PWR

 lamp flashes, and a trap is sent to the trap 

manager if SNMP is enabled and set properly. [

0 to -120; -90

]

•

SNR Threshold (for alarm)

—Value (dB) below which the sig-

nal-to-noise ratio is deemed to have degraded and a critical 
event is generated and logged. Under these conditions, the 

PWR

 

lamp flashes, and a trap is sent to the trap manager if SNMP is 
enabled and set properly. [

0 to 40; Not Programmed

]

•

RF Hopping Format

—Operation must be compliant with coun-

try-specific restrictions for the frequency band used. This option 
must be specified when the order is placed and cannot be mod-
ified in the field by the user. The available formats are:
•

ISM

: 902–928 MHz band

•

GSM

: 915–928 MHz band

•

SPLIT

: 902-907.5 and 915-928 MHz bands

•

CHANNELS

: 902–928 MHz, selectable hopping, from 1 to 80 

channels. This selection is available only on ESS-II or spe-
cially provisioned ESS units.

NOTE:

When using 

CHANNELS

 mode, all radios (AP and Remotes)

must be set to use the same channels in order to establish a link.
If this is not done, the radios will not connect.

NOTE:

ESS-II operates only in the 

CHANNELS

 mode, with selectable

hopping from 1 to 75 channels.

Channel Config
