Up to now, the whole country has only 11,591 5G BTS stations; 26% of the population has access to 5G services. Network operators plan to speed up the installation of 5G BTS. Photo: VNPT
For the record, the number of 4G base stations China's operators reported at end-June was significantly higher than CAICT's total. China Mobile had 1.65 million, China Telecom 1.05 million and China Unicom 770,000, for a grand total of at 3.47 million.
According to the Ministry of Science and Technology, as of early May 2025, network operators have installed 11,591 5G base transceiver stations (BTS), equivalent to 7.72% of 4G stations. About 26% of the population has access to 5G services. According to the plan, the number of 5G stations will gradually increase in the last months of 2025.
Mobile broadband access speed is 150.43 Mbps (assessed by Speedtest). Previously, after receiving the license to establish a network and provide services in 2024, the Military Industry-Telecoms Group (Viettel) launched 5G services in October 2024. Vietnam Posts and Telecommunications Group (VNPT) launched 5G in December 2024.
A flywheel-storage power system uses a flywheel for grid energy storage, (see Flywheel energy storage) and can be a comparatively small storage facility with a peak power of up to 20 MW. It typically is used to stabilize to some degree power grids, to help them stay on the grid frequency, and to serve as a short-term compensation storage.
Giant flywheels are to be installed around the UK to minimise the risk of blackouts as the power system goes carbon-free. Flywheels are energy storage systems that use surplus electricity to accelerate a massive metal “wheel”, thereby turning it into mechanical energy. To avoid energy losses, the wheels are kept in a frictionless vacuum.
These storage facilities consist of individual flywheels in a modular design. Energy up to 150 kWh can be absorbed or released per flywheel. Through combinations of several such flywheel accumulators, which are individually housed in buried underground vacuum tanks, a total power of up to several tens of MWh can be achieved.
A grid-scale flywheel energy storage system is able to respond to grid operator control signal in seconds and able to absorb the power fluctuation for as long as 15 minutes. Flywheel storage has proven to be useful in trams.

The billions of dollars are spent on producing war materiel, investing in military research and technology, and maintaining its military presence outside American soil. Currently, the US military is present in more than 80 countries with 750 bases across the globe in the guise of global peace-keeping and security (Vine, 2021).
These are bases, facilities and other installations that the United State Navy controls in other countries. Some bases may be joint use with branches of our other military, or they may be shared with other allied countries. For overseas bases not listed, try looking under the major command of that region.
