LIVE5G NSA (manage by DNB)
700 MHz (b28)
3.5 GHz (n78)
mmWave refers to higher frequency radio bands ranging from 24GHz to 40GHz (Up to 3 Gbps)
5G band : n258 = 26GHz
5G Band : n257 = 28GHz
mmWave 5G networks are ultra-fast, but they're also ultra-short range. To use mmWave technology, you need to be within about a block of a 5G tower, which isn't feasible in suburban and rural areas. mmWave spectrum is also blocked and obscured by doors, windows, trees, and walls, further limiting its available range, and because it requires so many towers for coverage, it's expensive for carriers to deploy.
Because of its limited range, accessing mmWave spectrum has only become possible over the course of the last few years due to technological advancements like Massive MIMO, adaptable beamforming, and miniaturization of complex antenna processing functions, and mmWave is still nascent technology that's in the process of being adopted.
mmWave's limitations make it best suited for dense, urban areas, or specific targeted spots like airports or concerts. In rural and suburban areas, mmWave technology is not practical because it doesn't have enough range, which is where the Sub-6GHz networks come in. Sub-6GHz 5G is faster than 4G, but it doesn't offer the blazing-fast speeds that you can get with mmWave. Since it has a longer range and can better penetrate objects, it's much more affordable for carriers to implement.
Sub-6GHz refers to mid and low-frequency bands under 6GHz. (Peak 5.8Gbps)
5G band : n78 = 3500MHz (or 3.5 GHz)
Most area Malaysia is using this frequency band
Low-frequency bands are under 1GHz (230Mbps)
5G band : n28 = 700MHz
