在移动通信系统发展的数十年中,第一代(1G)和第二代(2G)移动通信系统均经历了创立、发展并最终获得市场利益的过程,其成功的关键在于它们顺应了集成电路的发展走向,并突破了产品大规模生产的关口,而第三代移动通信系统(3G)却正面临着生存的考验。
In the decades of mobile communication system development, the first generation (2G) and second generation (2G) mobile communication systems all underwent the process of establishing, developing and eventually gaining market benefits. The key to their success lies in their compliance with the integration The development trend of the circuit, and broke through the large-scale product of the gateway, and the third generation mobile communication system (3G) is facing the test of survival.
