2022 Telecommunications Challenge

2022 Telecommunications Challenge

Challenge Requirements and Description

Happy Valley Communications is looking to design the next generation of telecommunications, “6G.” Your manager has tasked your team to develop a protocol for encoding, transmitting, rebroadcasting, and decoding a 3-byte message with high fidelity. In order to prevent interference of the transmitting and rebroadcasting signals, one transmission signal must encode data within the frequency of the wave (FM) and the other must encode data within the amplitude of the wave (AM). Similarly, one transmission signal must use light (EM waves) and one transmission signal must use sound waves to transmit the digital information. Once the transmission is received at the final destination, the signal must be processed and decoded by a computer program to output the original message.

Happy Valley Communications has set up a simple obstacle course to simulate customer use (see diagram below).
Signal 1 must travel down Leg 1 of the course which is a straight 150 feet long corridor. Then upon receiving this signal, rebroadcast it as Signal 2 down Leg 2, which is 10 feet around a corner (note, this means you will not be able to see your teammate you are transmitting Signal 2 to).

Engineering Problem Statement

Required

Type the problem statement here:

The Basic Physics of a Cell Phone Conversation

Required

Describe the basic physics of a cell phone conversation. Use your science notebook and system analysis if needed.

Include as many of the technical terms as you can: vocal cords, vibration, sound waves, microphone, signal processor, encode, digital information, electrical signal, AM, antenna, digital transmission, FM, radio waves, cell tower, fiber optic cable, cell tower, radio waves, antenna, signal processor, decode, speaker, sound waves, resonance, ear.

Response must be at least 3 complete sentences and should demonstrate your understanding of the technical terms in your own words (no copy/paste).

Transmission Protocol

Transmission Protocol

There are three constraints (limitations or restrictions) for the digital transmission (the sending of the message). 

The light and sound sources must be a stationary digital device (for example, a laptop computer or cell phone).

The information must be encoded within the wave, not in the movement of the device or your hands. 

The transmission can only use FM once and AM once, and light once and sound once.

Required

A constraint is a restriction or limitation.
A selection of the challenge description is below. Select the constraint for the digital information you will have to send. Hint: the limitation of the information relates to the size of the message you will send.

Your manager has tasked your team to develop a protocol for encoding, transmitting, rebroadcasting, and decoding a 3-byte message with high fidelity.
