Why can 5G transfer data faster than 4G?

Answer: It uses a broader band of radio frequencies to carry more data at once.

It squeezes the same data into fewer bits before sending it. — Compressing the user's files is not the mechanism behind 5G's higher radio capacity. Compression reduces the amount of data to send; a wider radio channel increases how much the link can carry. They are different ways of shortening a download.

It increases transmitter power so each signal reaches farther and stays strong. — Higher transmitter power is not what gives 5G its peak data-rate advantage. A strong signal can improve a connection, but wider channels can carry more data at once. High-frequency bands can offer wider channels, with coverage and obstacle-penetration tradeoffs.

It uses a broader band of radio frequencies to carry more data at once. ✓ — 5G can use wider radio channels to carry more data at once. Higher-frequency bands can provide large blocks of spectrum, although 5G also operates at lower frequencies. Actual speed depends on available bandwidth, signal quality and network load, so 5G is not always faster than 4G.
