Techniques for Higher Data Rates:
Wider Radio * Channel Bandwidths:
-
Increases symbol rate, enabling higher data throughput.
-
Wider channels can lower system gain, potentially requiring higher transmit power, larger antennas, or lower frequencies t * meet link budget needs.
Carrier Aggregation (CA):
-
Combines multiple contiguous or non-contiguous channels across bands t * increase throughput.
-
Intra-Band CA: Aggregates channels within the same band (e.g., E-band).
-
Inter-Band CA: Aggregates channels across different bands (e.g., E-band with traditional bands like 18 GHz) for added flexibility and interference resilience.
Adaptive Modulation and Coding (AMC):
-
Adjusts modulation and Forward Error Correction (FEC) rates in real-time based on channel quality.
-
Shifts t * lower modulation levels in poor conditions (e.g., rain fade), balancing data rates and link reliability.
High-Gain and Parabolic Antennas:
-
Large antennas (40+ dBi) narrow beamwidth, enhancing link budget and focusing energy precisely.
-
Precision Alignment: Essential at E-band frequencies, as small misalignments cause significant path loss due t * narrow beams.
Forward Error Correction (FEC) with Low-Density Parity Check (LDPC):
-
Provides robust error correction, reducing retransmissions and improving link quality.
-
Coding Gain: Effectively increases link margin by several dB, essential in high-frequency E-band t * maintain link performance.
Link Aggregation Protocols with Load Balancing:
-
Distributes traffic over multiple links, balancing load based on link quality and capacity.
-
Redundant Link Paths: Ensures traffic continuity during link degradation by dynamically rerouting t * alternative paths.
Dynamic Beamforming and Smart Antenna Arrays:
-
Electronically steers beams t * optimize link budget and adjust for minor misalignments or changing atmospheric conditions.
-
Adaptive Beam Shaping: Smart antennas reshape beam patterns t * minimize sidelobes, reducing interference in multi-link deployments.
Network for Interference Mitigation:
- Synchronizes transmission slots and channel access in co-located links t * reduce inter-link interference, particularly in dense network setups
E-band Channelization:
-
Wide channel options available in E-band (71-76 GHz and 81-86 GHz): 62.5 MHz, 125 MHz, 250 MHz, 500 MHz, 750 MHz, and 1000 MHz.
-
Allows scalable data throughput, suitable for high-capacity links (up t * 10 Gbps+).
-
Narrow beamwidths at high frequencies reduce co-channel interference but require precise antenna alignment.
