What is Mobile Frequency?
Mobile frequency refers to the radio spectrum allocated for transmitting data and voice communication over mobile networks. It is divided into bands, each serving specific purposes such as voice calls, texting, or internet connectivity. These frequencies are regulated by authorities like the FCC and ITU to avoid interference.
How Mobile Frequency Works
- Transmission and Reception: Mobile devices communicate with cell towers using radio waves, which connect to the core network to route calls or data.
- Division into Bands: Mobile frequencies are divided into different bands (e.g., 700 MHz, 1800 MHz), assigned to technologies like 2G, 3G, 4G, and 5G.
- Frequency Allocation: Operators are assigned specific frequency ranges to provide services in a region.
Types of Mobile Frequencies
1. Low-Band Frequencies
Range: Below 1 GHz (e.g., 600 MHz, 700 MHz).
Pros: Excellent coverage and penetration indoors.
Cons: Limited capacity and slower speeds.
2. Mid-Band Frequencies
Range: 1 GHz to 6 GHz (e.g., 1800 MHz, 2600 MHz).
Pros: Balance between speed and coverage.
Cons: May struggle in densely populated areas.
3. High-Band Frequencies
Range: Above 6 GHz (e.g., 24 GHz, 28 GHz).
Pros: Extremely high speeds for 5G networks.
Cons: Limited coverage and poor penetration through walls.
