Why 5G’s Speed, Latency, and Massive Connectivity Matter for the Next Decade

New infrastructure is a hot topic this year, and 5G, as the flagship, has become the focus of industry development and application.

Since the national new‑infrastructure push in March, 5G has accelerated: the three major operators released nearly 500,000 5G base‑station main‑equipment procurements, and the Ministry of Industry and Information Technology requires them to finish the year’s 5G base‑station construction by the third quarter.

The China Academy of Information and Communications Technology’s “5G Economic and Social Impact White Paper” predicts that by 2030 5G will generate over 6 trillion yuan in direct output and over 10 trillion yuan in indirect output, delivering huge economic benefits.

Compared with 4G, 5G’s core technical indicators focus on three main scenarios: high data rate, ultra‑low latency, and massive connectivity.

1. High data rate (eMBB) – Real‑world tests show 5G download speeds of about 300–600 Mbps, roughly 2–4 times that of 4G. Carrier aggregation can further increase speed depending on use cases and operator investment.

2. Ultra‑reliable low‑latency communication (uRLLC) – Latency below 1 ms (versus 100 ms for 4G) enables future factory‑floor applications requiring ultra‑high reliability.

3. Massive machine‑type communications (mMTC) – Designed for IoT scenarios with low power, low bandwidth, low cost and modest latency, 5G mMTC can support up to one million devices per square kilometre.

These three technical features will shape industry application directions, and virtually every 5G‑enabled industry solution depends on them.

Although 5G has been commercial for a year, many still feel no change, raising questions such as “Is 5G really fast?”, “Will it ignite industry opportunities?”, “Which core technologies link to which sectors?”, and “What are the most promising application scenarios?”.

At the “New Infrastructure – Alibaba 5G Insight” ebook launch, the strategic director of Alibaba Cloud Research Center answered these questions and shared Alibaba’s 5G research directions and fields.
