Prove Satellite Performance at Millimeter Wave Frequencies
白皮书
In our spectrum-constrained world, the idea of going to higher frequencies, where more spectrum is available, seems like a dream come true. For cellular non-terrestrial networks (NTN) and other satellite-enabled communications, millimeter-wave technology offers the preferred spectrum for wideband and ultra-wideband communications. Moving to millimeter-wave frequencies has advantages for satellite communications (SATCOM), ranging from higher data throughput to superfine range resolution using ultra-wide bandwidth. However, technological evolution always reveals new challenges.
These challenges increase pressure to drive down space and satellite application cost while accelerating design and manufacturing. As satellite systems add capabilities and reach new levels of performance, more uncertainty arises. Designers must pinpoint potential problems, verifying performance before launch and throughout the mission to guarantee success.
Wireless technologies increase signal bandwidth and use higher-order modulation schemes to achieve faster data rates. Wider bandwidth is a sought-after feature of millimeter-wave communications. However, wider bandwidth and higher-order modulation schemes introduce challenges related to link quality requirements at millimeter-wave frequencies. Wide bandwidths also introduce more noise as they enable high-throughput data, range resolution and accuracy, and low latency.
