Wireless Controller The next device is the wireless controller. Wireless controllers are centralized appliances or possibly software packages that are used to monitor, manage and control multiple wireless access points. They provide a number of different security features that aren’t possible with independent APS. You have multiple access points operating by themselves. Valves, you don’t get these capabilities. They can include interference detection and avoidance. So this can be achieved by adjusting the channel assignment as well as radio frequency power in real time load balancing. You can use that…

Chapter Introduction In this chapter, we’re going to be looking at network and security components and architecture. A secure network design is not going to be able to be achieved unless we understand the different components that have to be included in it and as well as the concepts of secure design that need to be followed. It’s true that many security features come at a cost of performance or ease of use. These are costs that most enterprises are going to be willing to incur if they understand some…

Tooltip Pages In the past few videos we’ve had a look at things like drill through which allow you to go to a secondary chart. And we’ve seen buttons and actions which equally allow you to go to various links. But what if you wanted not to go anywhere, but just to have more information to hand? Now, Tool Tips are little pieces of information, information that come up when you hover over objects and most of the time they are automatically controlled. So for instance, if I hover over…

Drillthrough In previous videos we had a look at interactions between visuals. For instance, I could click on Greater Manchester and I can see it highlighted. Or if I edit the interactions by going to Visual Tools format edit interactions, then I can change it from a highlight to a filter so that when I click on say Greater Manchester, all I see are Greater Manchester’s results. But what if I wanted to do more than that? What about if when I click on Greater Manchester I want to have…

Slicer Now there is one of a type of filter and it’s not strictly speaking of filter, it’s a visualization. And this visualization is called a slicer. And what it does is it goes through the slices data, which affects all visualizations on a particular page or in a particular report. So what I’m going to do is I’m just going to delete a few of these items and I’m going to insert a slicer in the spare gap. So it’s the one just to the left of the table…

11a. Adding Text boxes, Images and Shapes Hello and welcome to level four. And in this level we’re going to be adding more control to your visualizations. Now we’re going to start off fairly easily. We’re going to add additional elements to your pages that aren’t actual visualizations. For example, previously we have got this item, this visualization which you can click on and it highlights individual elements elsewhere and it’s also filters down on this table. But there’s no real way of knowing that without actually being a proficient…

Ribbon charts Hello and welcome to level five. In this level, we’re going to have a look at some of the other visualizations that we have not previously looked at. So in level two, we had to look at the table visualization. Level three, the matrix and the bar and the line charts. Level four, we’ve had a look at adding more control, more user interaction into your visualizations. So now we’re going to continue to expand our repertory of visualizations. So, first of all, we’re going to create a…

Maps Hello and welcome to level six. And in level six, we’ll be looking at maps and we’ll be looking at performance indicators. So in this particular section, we’re going to have a look at maps. So we’ve been looking at how we can have these six different regions, greater Manchester, Merseyside, South Yorkshire, Thailand, Weir, West Midlands and West Yorkshire being shown in different visualizations. But these, of course, are geographic locations. How can we put them onto a map? Well, there are two different types of map. There’s…

Gauges In these few videos, we’re going to go back to our HPI Admin data and just create a little dashboard. And the purpose of this dashboard is to introduce another set of visualizations. And this is specifically mentioned in the Power Bi exam as measure performance by using KPIs gauges and cards. So we’re going to start off with gauges. Gauges are semicircles, which show how much you have done towards a certain target. So over here, this is a gauge. So if I click on that and I…

Use groupings and binnings In this video, we’re going to group together values. And there’s two ways of doing this depending on whether you’re grouping together numerical or time data or whether you are grouping together text, for instance. So let’s create a very simple chart. So this is going to be a clustered column chart. And we’re just going to have region name in the axis and sales volume in the values. So we’ve got Greater Manchester, West Midlands, West Yorkshire, Merseyside, South Yorkshire and Tyne and Wear. Okay,…
