一批速度更快、传输距离 更远的新型无线局域网产品 相继上市了,我们对一些这 样的新产品进行了测试。 无线网络的发展正在加速、分化。许 多使用新天线技术(antenna technology) 的802．11a/b/g标准的网络产品显示了令 人瞩目的速度和覆盖范围。这些进步会使 人们感到欣慰,通过Wi-Fi拷贝一部电影 也不会太痛苦,也不会再经历盲区的折磨 和超出信号覆盖范围的情况。 新天线技术以多人多出(MIMO)为 特征,原因是基于此技术的产品通过使用 多个智能天线,利用客户端设备的定位来 优化传输,从而提高吞吐量和覆盖范围。 与此相对的是,老的Wi-Fi产品通常向四 面八方传送信号,而不考虑接收信号的地 方在哪里。MIMO产品的销售商声称其在 性能方面无可比拟。
A batch of new wireless local area network products of faster speed and longer transmission distance have been put on the market, and we have tested some of these new products. The development of wireless networks is accelerating and differentiating. Many 802.11a / b / g standard networking products that use the new antenna technology show impressive speed and coverage. These advances will make people feel relieved that copying a movie over Wi-Fi will not be too painful, and will not go through the torment of blind spots and beyond the signal coverage. The new antenna technology is characterized by Multi-person Multiple Output (MIMO) because products based on this technology improve the throughput and coverage by using multiple smart antennas, utilizing the positioning of the client device to optimize transmission. In contrast, older Wi-Fi products typically send signals in all directions, regardless of where the signal is received. Vendors of MIMO products claim they are unparalleled in performance.
