From the above table, the main frequency bands in Asia are the Sub-6G and the mm-Wave part of 28G.
At present, BTL has been subordinated to Sub-6G testing and can perform related RF/EMC/SAR testing. We also have a strong IA team to assist with South Korea's 5G certification. If you have 5G technology or certification issues, welcome to come. advisory.
