What's a G? The mobile industry refers to new "generations" or Gs each time it introduces a new industry-wide technical standard and rebuilds the fundamentals of mobile data networking. That's been happening at roughly a once-a-decade pace.

How it works: The initial version of 5G builds on today's LTE networks but introduces a new type of radio technology that responds more quickly, moves data faster, and uses less power.

Sound smart: Here are some key 5G terms.

  • Small cells — as the name implies, these devices for providing network service are smaller than a traditional cell tower but as a result have to be placed much more closely to one another. Critical to 5G, carriers have also been using small cells to improve their 4G LTE coverage and capacity in cities.
  • Latency — the amount of delay, or lag in response, in a network. One of 5G's main advantages, along with faster speeds once a response has started.
  • Spectrum — the frequency of airwaves used to carry, among other things, cell phone signals. 5G uses a wide swath of airwaves, including higher frequencies than have been used in the past.
  • Millimeter wave — This ultra-high-frequency spectrum is key getting the fastest speeds out of 5G. These signals are also fragile, traveling comparatively small distances and easily blocked by buildings and other objects.

Qualcomm CEO Steve Mollenkopf will step down from his position in June, after more than 26 years with the company, according to a press release out Tuesday.

A Uganda Olympic team member tested positive for COVID-19 upon arrival in Japan late Saturday, officials said.

Why it matters: Japan's government has faced criticism for vowing to host the Tokyo Games next month as coronavirus cases rise. The Ugandan team is the second to arrive in Japan after the Australian women's softball players, and this is the first COVID-19 infection detected among the Olympic athletes, Al Jazeera notes.
