Ubiquiti AirFiber AF60 CPE, 60GHz and 5GHz

Gbps (Gigabits per second) is a unit of data transfer rate equal to one billion bits per second.

In telecommunications and network engineering, Gbps defines the bandwidth capacity of fiber optic infrastructures (FTTH) and core backbones. This metric quantifies the effective throughput of a communication channel, enabling massive packet transfer without link saturation. Implementation at the physical layer requires high-speed interfaces like Gigabit Ethernet to manage digital signaling and ensure data flow integrity across the network nodes.

Bandwidth Management and Network Capacity

A 1 Gbps link allows for efficient service segmentation via VLANs and traffic prioritization through QoS, supporting data-intensive real-time protocols without encountering bottlenecks at the hardware level.

Advantages of Gigabit Connectivity

• Significant reduction in latency for critical applications.
• Support for multiple concurrent 4K/8K video streams.
• Enhanced cloud synchronization and backup speeds.
• Seamless scalability for IoT device density.

Gbps is the primary performance indicator in modern broadband and enterprise networking.

• 21 DBM-> 125 MW> Maximum output power for a mobile phone UMTS/3G (phone power class 4).
• 15 DBM-> 32 MW> Typical power transmission WiFi laptops.
• 0 DBM-> 1.0 mW = 1000 ?W-> Standard Bluetooth Class 3 coverage 1m.
• DBM- -10> 100 ?W-> Typically the maximum Potentiometeria that can be received on a wireless network (-10 to -30 dBm).
• -194 DBM-> 0.00004 AW-> thermal noise bandwidth of 1 Hz in outer space (4 kelvin).

dBi (decibels relative to isotropic) is a logarithmic unit of measure that expresses the gain of an antenna compared to a theoretical isotropic antenna that radiates energy uniformly in all directions.

Imagine a light bulb that shines in all directions equally. If you put a reflector on it so the light concentrates in a single spot, that light will be much more intense there. The dBi measures how much extra "strength" the signal gains by focusing it in a specific direction instead of wasting it everywhere.

Directivity and Energy Focus

A higher dBi value does not mean the antenna produces more energy, but rather that it redirects existing energy more precisely, narrowing the beam angle to reach greater distances.

Advantages

• Increased range for wireless links.
• Reduction of side and rear interference.
• Better signal-to-noise ratio in the main direction.

A higher dBi value indicates a more directional and longer-range signal.
