:arrow_right: Correct answer: Letter c.

3.5G (HSPA/HSPA+) marked the first widespread availability of truly high-speed mobile data, with download speeds reaching multiple Mbps, enabling more advanced mobile internet services. While 3G introduced mobile data, its speeds were relatively low compared to 3.5G.

Q. In which generation did mobile technology start supporting high speed data?**

a) :x: 2G
→ Incorrect. 2G had very limited data capacity, mainly for SMS and low-speed packet data.

b) :x: 3G
→ Incorrect. 3G introduced mobile data but at relatively low speeds (hundreds of kbps to ~1 Mbps), not yet “high speed” by modern standards.

c) :white_check_mark: 3.5G
→ Correct. 3.5G (HSPA/HSPA+) significantly increased mobile data speeds (several Mbps), considered the real start of high-speed mobile data.

d) :x: 4G
→ Incorrect. 4G greatly improved speeds and latency but was not the first generation to support high-speed data.
