The transceiver is suitable for industrial environments

Hi

What is the transceiver is suitable for industrial environments ?

Thanks.;-);-);-)

A transceiver is a combination transmitter/receiver in a single package. The term applies to wireless communications devices such as cellular telephones, cordless telephone sets, handheld two-way radios, and mobile two-way radios. Occasionally the term is used in reference to transmitter/receiver devices in cable or optical fiber systems.

In a radio transceiver, the receiver is silenced while transmitting. An electronic switch allows the transmitter and receiver to be connected to the same antenna, and prevents the transmitter output from damaging the receiver. With a transceiver of this kind, it is impossible to receive signals while transmitting. This mode is called half duplex. Transmission and reception often, but not always, are done on the same frequency.

Some transceivers are designed to allow reception of signals during transmission periods. This mode is known as full duplex, and requires that the transmitter and receiver operate on substantially different frequencies so the transmitted signal does not interfere with reception. Cellular and cordless telephone sets use this mode. Satellite communications networks often employ full-duplex transceivers at the surface-based subscriber points. The transmitted signal (transceiver-to-satellite) is called the uplink, and the received signal (satellite-to-transceiver) is called the downlink.


yes specified transreceiver is suitable for industrial environments...

Industrial environments are hot and noisy. So first you would pick a transceiver that can handle extended temperature ranges.

A lot of electronic noise will be contained in the 30 MHz (an its harmonics) and lower frequency range, so a communications link at 915 or 2450 MHz will, in general, do better.

A spread spectrum system, especially one that monitors the available channels and avoids heavily congested ones, is preferred.

A simple modulation scheme, such as FSK, 4FSK, bpsk, or qpsk might get thru the best. More complex modulation schemes like ofdm might do well for broader band signals in an indoor environment. You want to avoid ASK or OOK modulation.

Hi,
thanks for your answer
I have two way:
1- use modules, such as zigbee , ...
2- design circuit transceiver that is suitable for environments industrial
I like use module what is your idea?
Plz help me!!!

you just go through which is suitable for you

What is your requirement? Such as range, temperature, environment, etc?
