There's a joke, "How hard can it be not to install wires?" However, it's a good question, so let's think through this a bit.
Let's say you are deploying a new wireless network. Maybe you had it thrown at you already purchased and delivered. You just get to implement it. What fun! Maybe it's "just" an upgrade, so can't you just swap things out?
Things you need to consider: What model are the APs? Do you have enough for coverage? More importantly, what about capacity? If not, you may have to pick and choose the most important locations to get quality wireless and accept lower quality wireless at less critical spots. Maybe it's a network designed for 2.4GHz radios and you are upgrading with the expectation of 5GHz coverage. 5GHz needs more radios to achieve the same coverage, so a simple swap might not do the job. Especially if it's a 2.4GHz network that was focussed only on coverage.
Instant or controllers? Do you have multiple controllers for high availability? What happens when a controller goes down? If it's not too late, is the controller the right size for this deployment? Not long ago, I was giving some advice to a friend who had a pallet of gear handed to him and told to deploy it. Among other things, it included a single controller that was overkill for the deployment, when for less money a pair of smaller controllers would have been a better plan. We want to avoid these kinds of problems when we can, but make the best of them when we must
所以，关于无线的有趣的是它仍然需要电线。如果您无法在那里运行电缆或运行太长，那么最好地找到AP的位置并不重要。也许它将建筑月光的建筑师作为无线工程师，有助于“WAP”位置在建筑物周围传播。或者也许是一个布线承包商，他们用一些随机电缆为您提供了RF设计意见。通常太多，有时太少了，几乎总是不在正确的地方。理想情况下，我们得到了我们真正需要它们的电缆，但有时我们必须做出最好的事情
You also need a place to connect that cable. You may need more switches or an upgrade to the existing switches. Are there open ports? Are the switches PoE? Do they have the PoE budget to support the APs you are adding? Do the switches support 802.3af (15.4W max) or 802.3at (30W max)? Better make sure the APs don't require more power than you have available. Now that you are adding load to your switch, do you have the capacity on your UPS to support this additional load? That's probably not a problem, but it's worth checking.
Do you have sufficient bandwidth in the uplinks to support the requirements? What about in a year or two? Consider how the network may change in the next few years and whether it will be able to continue to meet expectations. For example, I've been designing everything for 5GHz for the last several years, even though there was no real demand for it until about a year ago. Given the explosion of 802.11ac devices, I'm very glad I did even though many of those deployments are still only 802.11n. Those 802.11ac devices are making use of that 5GHz spectrum, adding capacity for everyone.
How are clients going to authenticate? Open network, username/password, PSK, certificates? Do all the clients support your authentication protocol? Does the infrastructure actually support it? It's great to say everything will get an X.509 certificate to authenticate, but does the required PKI infrastructure already exist? If a directory like Active Directory is already there, it probably does. Pushing out certificates to AD domain joined machines isn't difficult, but is it ready for BYOD? Now you're looking at something like ClearPass to help manage the on-boarding process.
你需要多少个SSID？您在同一SSID上需要多个类用户吗？如何命名为此，所以用户可以轻松确定正确的SSID？您是否考虑过身份验证系统，可以将同一SSID的用户分配给不同的VLAN，以简化用户的界面？
有客人网络吗?它会有一个俘虏portal? Who's building that web page? Is it a static page or dynamic? What serves the portal pages? Do guests need to accept an AUP? Will you limit speeds or connection time? Do your guests need sponsorship? Depending on what is needed, the complexity can grow very quickly
它不如何努力部署电线？这取决于您是否在部署之前或在部署期间进行计划。现代无线部署并不简单，但提前规划所有这些事情会使它变得更加容易。这里没有覆盖，但是在他们有机会咬你之前，这个想法是让你开始思考所有细节。如果我错过了你最喜欢的预部署清单项目，请留言！
