Full-Duplex ESA Antenna: Simultaneous Transmission and Reception

Alpha2 Jumbo ESA antenna offers full-duplex to simultaneously transmit and receive data in different directions. This eliminates delays between data transmission and reception, enhancing bandwidth efficiency in two-way communications.

Key benefits:

• More data to be processed faster
• Advantageous for high-capacity data communications such as high-speed Internet, real-time streaming, and high-resolution video transmission

Full-duplex ESA antennas are highly compatible with next-generation communications technologies such as 5G and 6G. These technologies require high-speed data transmission and low latency, making full-duplex mode essential.

Excellent Alpha OTM antenna performance with fast beam switching speed

• Full Switching Time: <0.5ms
• Satellite Switching Time: <0.5ms

Fast beam switching speed enables satellites to track and communicate with multiple ground terminals or fast-moving low Earth orbit satellite users or base stations. This is especially advantageous for communication with moving aircraft, ships, and vehicles.

Signal interference is a major problem in satellite communications. Fast beam switching speed allows signals from specific users to be quickly switched to another direction to minimize interference. This allows for cleaner and more stable communication signals.

Fast beam switching speed enables efficient allocation of network resources. Antennas can quickly switch beams as needed to optimize resources and improve the overall performance of the network.

Electronically steered beams without using traditional mechanical motors

Without mechanical motors, ESA antennas can steer beams rapidly, avoiding mechanical problems such as wear, failure, and maintenance. This greatly improves the reliability and lifespan of the antenna.

Electronic beam steering is much faster than mechanical motors. This is a significant advantage in multi-satellite tracking, etc. The fast response speed minimizes communication delays and maximizes efficiency.

Electronic steering allows for precise beam steering. This allows for precise control of the directionality and strength of the signal, minimizing interference and improving communication quality.
