The transceiver NR-486 is a tri-band analogue/digital device.

​

Operating modes:

• VHF (Analogue/Digital): 140~174MHz

• UHF (Analogue/Digital): 430-540MHz

• High-UHF License-free (Digital): 860~890MHz 

 

In UHF and VHF bands the transceiver can be operated either in traditional analogue mode, or in Frequency Hopping Spread Spectrum (FHSS) mode with low rate hopping (33-50 hops/sec).

​

Also the unit can be used in NetRadios® networks, having the complete set of mesh network features.

 

NR-486 provides cross-band communication between either VHF or UHF bands and NetRadios® Hi-UHF band.

 

The device can be programmed either with buttons or with a computer, connected to the device with USB-type cable.

 

AES/DES cryptographic protection can be employed in digital transmission modes (optional).

 

GPS receiver can be embedded into the transceiver (optional), and send location data in one of three selectable modes:

- Every time when TX starts

- Every period of time, which is programmable

- By request from remote device

 

The housing of the transceiver is shockproof, dust and water protected in compliance with IP67.

 

NetRadios® system’s main features:

* Fast deployment of the Network

* 100% coverage of any object (installations, complex buildings, territory)

* Unlimited number of subscribers distributed among 256 groups

* Re-transmission of received voice and data by each user within a network

* Data can be relayed up to 56 times without degradation

* Absolute autonomous operations by a group of users

* Data exchange among terminals, which are connected to devices of the system (i.e. portable computers, navigation devices, etc.)

* Encryption of transmitted data (AES or DES)

* Individual, group and conference calls within the radio network

* Remote monitoring and control of the radio network’s operating modes

* Real time control of mobile operators’ movements and location

* Small dimensions and low weight of all individual use devices.

* No need for licensing because of extremely low radiated power of communication units.
