If you’ve chosen to move forward with an 11ac deployment, you will be faced with one of two deployment options: greenfield or upgrade. Either you are installing a Wi-Fi infrastructure for the first time or you are upgrading an existing deployment. Given the pervasive nature of Wi-Fi technology, it’s far more likely that you are considering an upgrade. You may also be facing a fiscal decision on whether your existing equipment has reached the end of its useful and/or cost-effective life.
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). These two types of systems are very different, and deployment of 11n or 11ac as a replacement to 11a/b/g systems should always entail a new network design, survey, and validation.
There are, additionally, very few scenarios in networking where eliminating a device, or device type, can yield a 10-fold performance increase. Removing legacy 11a/b/g clients and APs from the network can produce just such an increase due to removing the need for some MAC layer protection mechanisms. If an end user wants to maximize ROI and to experience the benefits that 11ac can bring, they must aggressively remove legacy clients and APs.
So, which option is best for you?
