Free-Forming One-Way Network
- Summary
- The Free-forming One-way Network (FON) is a system of one-way or single-channel communication network utilizing electromagnetic radiation signals of a fixed single or narrow-band frequency in free air space. It consists of a plurality of transmitters and a central receiver in which each message is encoded in a wave train and is tagged with a sender identity. The central receiver, which can be a single unit or a plurality of units connected in cascade, detects the messages in the free air space and sends them along to a central processing unit (CPU) for message handling.
Such a one-way network is useful for recording group responses to a prompt such as an action, a question, or a stimulus; particularly in those gatherings that require the completion of the registration of all responses in a time span of the order of minutes.
Many communication network systems have been proposed previously. They are mostly wired and more expensive to implement due to the installation costs of electrical wires and optical fiber cables. Also, they are difficult to transport. Other wireless systems that use multi-channel communications are restrictive in use, complicated and costly. However, single-channel communication ones does not allow networked operations.
