Answer 1

Answer: The wireless signals can carry large amounts of data at high radio frequencies.

Explanation: the others don’t specify the kind of signal

Answer 2

The statement ''the wireless signals can carry large amounts of data at high radio frequencies' supports the student’s claim.

• A wireless network is a computer network that uses wireless connection data to connect with other computers.

• The signals (wireless signals) are electromagnetic waves that can travel through the air.

• There are wireless computer networks that use ultra-high frequency (UHF) frequencies, i.e., frequencies that range between 300 megahertz (MHz) and 3 gigahertz (GHz) of the electromagnetic spectrum.

According to the range, there are three main types of wireless computer networks:

• Short-range wireless computer networks
• Medium-range wireless computer networks
• Wide-area (range) wireless computer networks

In conclusion, the statement ''the wireless signals can carry large amounts of data at high radio frequencies' supports the student’s claim.
