Data transfer rate across different channels
Wi-Fi 5 GHz: Up to 400 Mbps (depending on operator): USB 2.0: Up to 300-400 Mbps (more stable): Bluetooth 4.0/5.0: Up to 2-3 Mbps (for text and light web browsing only)
Comparison of the 2.4 GHz and 5 GHz frequency bands
Modern models iPhone support operation in two frequency ranges, each of which has its own advantages and disadvantages. Range 2.4 GHz Provides greater coverage and penetrates walls better, but is more susceptible to interference from household appliances.
