如果您选择继续 11ac 部署,那么将面临着选择其中一种部署:新建或升级。首次安装 Wi-Fi 基础设施或升级现有部署。鉴于 Wi-Fi 技术的普遍性,您很可能会考虑升级。您可能还面临着财务选择:您现有的设备是否达到了寿命和/或成本效益年限。

When budgetary constraints allow it, “rip-n-replace” deployments can be exciting… so exciting in fact that some network managers miss the significance of moving from a legacy Single Input Single Output (SISO) system (e.g. 11a, 11b, & 11g) to a Multiple Input Multiple Output (MIMO) system (e.g. 11n and 11ac).这两种系统非常不同,部署 11n 或 11ac 进而取代 11a/b/g 系统始终需要新的网络设计、调查和验证。

There are, additionally, very few scenarios in networking where eliminating a device, or device type, can yield a 10-fold performance increase.从网络中删除旧版 11a/b/g 客户端和 AP 会实现此类增长,原因在于不再需要部分 MAC 层保护机制。如果最终用户希望最大化 ROI 并体验 11ac 带来的优势,则必须逐步删除旧版客户端和 AP。

So, which option is best for you?
