Telecommunication has come a very long way over the years. The technology, though, appears to be simplistic yet carries intriguing sophistication. Now, wireless systems are highly regarded and used as entry control systems in houses and workplaces. Read the post below to understand the historical development of wireless intercom systems.
What is a Wireless Intercom?
A wireless intercom system primarily operates using either the electrical wiring system of a particular building, radio frequencies, WIFI, or a digital spectrum spread. The market is filled with a whole range of wireless intercom systems. Moreover, there are never before seen systems in there, and their technology is becoming intriguing and complex by the day. Going wireless is the key of the age.
History of Wireless based Intercoms
The conception of wireless intercom system is regarded to be due to John Bardeen’s works on the transistors. It is due to his work that multi-directional communications could develop. The latest in this field could be the WiFi intercom technology.
Furthermore, in the year 1982 for the first time, an intercom system was developed which had both audio and visual capabilities. Also, these systems came to be used in not only communications but also for security. For instance, the intercoms that operate on radio frequency have started being used in as baby monitors.
Some wireless intercoms come with battery operation feature. This Business Intercom System promotes portability and thus efficiency.
Issues of costing
Wireless phone intercoms systems, on the other hand, are cost efficient to a large extent. The basic costing that would be involved to retrofit the building or the home itself would mean quite a lot of extra spending.
Intercom systems do not have networks recurring cost involved. Whatever the first cost is incurred during the installation process, it essentially remains fixed to that. However, of course, there are other costs such as electricity and maintenance. Moreover, apart from that, there are endless uses for these systems just because of their practicality and efficiency.
The first intercom systems operated using the same wiring network involved in any other form of telecommunication. It communicated through low voltage signal wires. These cables were usually installed in the walls of a building. Though retrofitting older buildings and houses was an option, but again the costing involved was quite a hindrance.
Later on, a new system would come up. It operated in a non-radio wireless format. They again used the electrical wiring system of a building. They became popular in offices and home environments in the form of wireless desk intercoms. The purpose of the intercom is not limited to two-way communication alone.
In most cases the issues of privacy remain secured in a wired intercom system. Though there can be wiretappings, insertion of bugs et cetera. These are the very generic issues. On the other hand, the issues of privacy are the major problem(s) of a wireless intercom service. The major issue here is that of encryption.
The best way probably to avoid this obstacle to a great extent would mean for one not to use publically available frequencies.
In the current wireless intercoms for homes and the general spaces as well, the frequency of communication is set at 4KHz. This indeed reduces voice clarity and quality in certain situations.
In the United States of America, an encrypted wireless intercom device was first used in the sport of American football in 1996. Subsequently its usability improved and so did its use. It was employed in the Super Bowl in 1999 for the first time. Moreover, as the technology was developed, so did the increase in its use.
History of wireless intercoms has been quite interesting. It has developed as a prominent and handy device. It is not only efficient and cost effective but also most essential for office environments. Its popularity has rather increased manifolds and is also found in the new apartment and/housing societies.
Since these systems are wireless – it yet remains the most secure and private way to communicate. The risk is mitigated by the added benefits of encryption. These systems suffer from interference in the signals. These systems show promises in medical centers and hospitals which require constant monitoring of patients.
The wireless intercom systems have immense potential in disaster management as well. Essentially, the possibilities are only limited by one’s imaginations.
