The Evolution of Wireless Radio Transceivers

In today’s constantly evolving world where wireless radio transceivers is as easy as using your phone and dialing a number to talk to someone miles away, it’s extremely difficult and somewhat unimaginable to think just what life was like before we have the means to communicate with anyone, anytime and anywhere we want. But before the 19th century, this wireless radio communication that we experience now was simply a fantasy. In fact, even after the development of the first ever radio in the late 1800s, it several years before radios became a regular part of people’s lives. Indeed, the development of the radio completely changed the world’s way of communication- making everything so much easier and more convenient. All the benefits of the invention of the radio wouldn’t be possible without the creation of this remarkable device called the transceiver.

Perhaps a simple definition of a transceiver is a device that can transmit and receive information through a transmission medium. In other words, a transceiver is a combination of the transmitter and the receiver, thus the name transceiver. Transmission by a transceiver is commonly accomplished through radio waves, but other options are wired connections, optical fiber and communications satellites.

Did Somebody Say “Walkie Talkie?”

Imagine carrying a backpack with a “radio” inside just to communicate with other people? Yes, we’re dead serious. That is exactly what the transmitter and receiver is like before. It was in 1938 when the U.S Army Signal Corps developed the SSCR-194 and -195 systems. They were heavy, bulky, consumed too much space and unreliable most of the time. They also can cover only 5 miles. Thanks to brilliant minds, the company Motorola was soon contracted to create the first ever handheld transceiver. It was called the SCR-536, or most popularly known as the “walkie-talkie.”

The Very First Phone You Can Hold In Your Hands

It was only during the late 70’s and early 80’s when the remnants of the very first mobile telephones that we have now can be seen. There was even a heated competition between the companies Motorola and Bell Systems, to create the first ever handheld cellular phone.

The Birth Of The Wireless Radio Transceivers

It was during the 1920s when the first ever transceiver first appeared. Before that, receivers and transmitters were created separately and if you have an equipment or device that needs to receive and transmit data, then you need to buy both components separately.

One type of the fully developed wireless radio transceiver is the analogue transceiver. The analogue wireless radio transceiver uses frequency modulation to be able to send and receive data. This means that the complexity of the data that can be broadcasted is quite limited, however, the analogue wireless radio transceiver is used in several emergency communication systems as it operates efficiently and reliably. When it comes to cost, the analogue wireless radio transceiver is also much cheaper than the digital wireless radio transceiver. That explains why the analogue wireless radio transceiver is popular with the CB and HAM radio communities.

Another type is the digital wireless radio transceiver which sends and receives binary data over radio waves. This means that more types of data can be broadcasted. The digital wireless radio transceiver is most commonly used by fire and police departments as it includes video and encrypted communication. The digital wireless radio transceiver is also clearer and more detailed than the analog counterparts which is why most modern wireless devices used digital transmissions.

Gedge System’s Wireless Radio 868 MHz Transceivers

Wireless communication is particularly advantageous where laying serial communication cables turns out to be expensive, when it requires trenching and conduit pipes. Going wireless also protects the entire weighing system from power surges caused by lightning.

Gedge System’s Wireless Radio 868 MHz Transceivers form a network which enables wireless communication between various devices connected into the system. This includes weighing indicators, remote displays, computers, and even printers. Both the RS-232 and RS-485 interfaces are available. These units can work in one-to-one or mesh mode (up to five units). The device comes in a durable industrial housing made of ABS and is suited for both indoor and outdoor use. The transparent front cover ensures easy verification of configuration of the unit and electrical connections without the need to disassembly. Gedge System’s Wireless Radio 868 MHz Transceivers has a line-of-sight range of approx. 1000m (3281ft) with an SMA antenna connector located outside the housing, and an antenna that comes with a 5m cable to allow more flexibility for installation locations.

The transceiver indeed went through a transformation over the years but the goal remains: to allow each human being the ability to build communication with anyone, anywhere, anytime. To make sure that you pick the right wireless radio transceiver for your application, the engineers from Gedge Systems will be pleased to give you advice on the best possible solution.
