Telcos prepare plans to prevent network congestion at TetLocal mobile carriers have unveiled plans to cope with possible network glitches during the upcoming Lunar New Year holiday, or Tet, which falls next Friday. Notably, this is the first Tet the Viettel network has included 4G which now accounts for half of the total just after over 10 months of operation. Viettel has recently installed 1,000 4G cell towers, bringing the total number of 4G transceiver stations to over 37,000 nationwide. Given the strong growth of mobile internet services, MobiFone has also raised its internet capacity to around 200 Gbps, an 80% rise against 2016. It has plans to adjust network configuration and use mobile base transceiver stations in crowded sites.
