Why different phones different range of frequency?
5G sub-6GHz uses the standard (LTE) bands. These include 600-960MHz and 1700-2400MHz. They often also use the ISM bands, specifically the 2.4GHz band (although these cannot be 'reserved' for the phone.) These also include the 802.11 (wifi) and Bluetooth frequencies.The Telco 5G use which frequency?
Of course. Many phones have limited bands they can transmit and receive on. Often they are optimized for a single carrier, who uses specific ranges of frequencies. Also most carriers do not support millimeter wave.Is it possible my 5G phone not supported by certain Telco?
