The 5G networking hype has been in full force since Qualcomm declared “5G is here, and it’s time to celebrate” in February of last year. The reality, however, has required patience from consumers due to the time needed to roll out the new networks and the dearth of applications to put additional speed to compelling use.
A year after South Korea launched the world’s first full commercial 5G network and months after China opened the world’s biggest commercial 5G network, Bloomberg News reporters tested the leading carriers in both countries to see how far 5G has really gotten. Tests in Hong Kong and Tokyo also showed similar results -- gaps in coverage that could leave most early adopters waiting for networks to reach full speed.
Carriers aren’t moving quite as fast. They’re investing billions of dollars to set up and expand their 5G networks, but the technical design of this new standard demands high network density to provide the advertised stratospheric speeds. Once they have enough masts in place, they aim to recoup the initial costs by offering more bandwidth-hungry add-ons, such as Nvidia’s GeForce Now game-streaming service, which SoftBank Corp. launched in Japan on June 10.
Where it’s available, even without hitting its max theoretical speeds, 5G is an impressive upgrade for most consumer applications. For example, at a gigabit per second (1Gbps), a user could download a 9-hour audiobook in less than 1 second, according to Fastmetrics, a U.S.-based internet service provider. Even at 1/10 of that speed, 100 megabits per second, a 45-minute TV show takes only 16 seconds, Fastmetrics estimates.
Carriers in North America, Europe and Australia have also set up 5G, with so far underwhelming results for consumers. In March tests conducted by RootMetrics in the U.S., the choice appeared to be between fast speed with negligible availability -- Verizon Wireless Inc. recorded a max speed of 846 Mbps with 3.1% availability in Chicago -- or wider availability without much of a speed bump -- T-Mobile US Inc. covered 57% of Washington but at a less impressive 148 Mbps.
While 5G uptake has been incremental, companies that make parts for the phones are betting on a wave of upgrades to drive smartphone demand and help spur economies from Taiwan to South Korea. To test download speeds and coverage, Bloomberg sent four reporters out into Seoul, Beijing, Tokyo and Hong Kong with 5G phones and speed-measuring apps. Here’s what those tests showed:
SEOUL (SOUTH KOREA)
KT Corp, the No. 2 South Korean carrier, has improved 5G service since the commercial debut in April 2019, though it still lacks the high-frequency airwaves necessary to reach top download speeds in the range of 20 Gbps. SK Telecom Co., the country’s largest carrier, achieves a download speed of 1.5 Gbps inside its headquarters, which drops to 1 Gbps in the same building’s lobby.
KT’s average 5G data speed ranges between 800 Mbps to 1 Gbps. The company responded that it is hard to simply compare data speeds in South Korea, which has nationwide services, with other countries that only have test services or have services in a few cities.
In Beijing, tests using a Huawei P40 Pro phone showed 5G service was consistent enough to play high-definition (1080p) video while riding in a car. There was no 5G signal inside the subway and the shopping mall in Guomao, an area at the centre of the Beijing Central Business district. Most of the Zhongnanhai district, home of the central government, has no 5G coverage, according to a map provided by China Mobile. A China Mobile representative in Beijing emailed a video showing download speed exceeding 1.1 Gbps at Beijing Daxing International Airport. The representative had no further comment.
Tests using a Huawei P40 Pro showed streaming of high-resolution 4K video was smooth outdoors even in a moving vehicle. The fastest download speed was recorded in the carrier’s flagship store in the city’s central business district. According to Alex Cheng, China Mobile principal engineer, the carrier expects its 5G network to “penetrate deeply” in Hong Kong.
At two locations in the city, the 5G signal was strong inside the Docomo shop but became unstable a short distance away from it, using a Samsung Galaxy S20 phone and Netflix’s speed test app. Both of Tokyo’s main airports, two Olympics facilities and Tokyo Sky Tree are among the covered spots. Two more waves of 5G network expansion are planned by the end of July and end of October, the carrier said. Smartphone makers have swept in with a flood of 5G devices this year with Samsung, OnePlus and others pushing the new technology without asking for much higher prices or design compromises. Millions of 5G phones have already been sold, and for the billions of people not yet on the bandwagon, the new wireless standard will soon be the default option anyway. But it might take few more months for 5G to be available widespread with high speeds and minimal latency.
