Ingenu, a link to their site. I wasn't able to determine the topology of it, I'm not sure, I think it's a star. That's what the question mark is there, I don't have 100 percent confidence in that. They claim range up to 50 kilometers. I went to their website and they still have this example as a success story, I guess. 17 towers covers the whole Dallas/Ft Worth area which is about 2,000 square miles covered with 17 towers, which seems to me to be a decent coverage with only $17. Although, it's not super high-speed, so it's for low data need applications. Just like the Internet has connected people around the globe, the Internet of Things is poised to connect the objects and machines we haven't all around us. Everything from street lights to parking meters will communicate to make our cities and homes safer. More energy efficient, and better places to live. Everyday, billions of people use cell phones, but cell networks can't handle the hundreds of billions of devices connecting to the Internet of Things. Cell networks were designed for people not machines. That's where RPMA comes in. RPMA or Random Phase Multiple Access is a wireless technology designed and built for machines. Because it uses the universally available 2.4 Gigahertz wireless spectrum, RPMA could be deployed in any country on the planet. RPMA devices are smart, they're designed to communicate freely, and independently. An RPMA device only transmits as loudly as needed. Not at a low, but at a whisper. That way, they play nice with neighbors, and every message gets through. Our devices are energy conscious. Since each transmission uses energy, they choose the right data rate for the job, transmitting in the shortest time possible. An RPMA device can last for years, even decades between battery charges. With RPMA, hundreds of billions of machines will have reliable secure two-way connectivity on an out-of-the-box ready professionally managed network. RPMA from Ingenu, it's simply genius. That brings us to our next one known as WiMAX, it stands for Worldwide Interoperability for Microwave Access. Designed for the "last mile", this is a term that was used widely in the late 90s and the early 2000s, where thinking was fibre optic cables would be run everywhere, and then to get to the final destination: the home, the factory, the business would go wireless for that particular last mile. It is also IEEE standard, so it's 802.16 you can go, take a look at that. Supports a mesh topography. Operates in the 2-60 Gigahertz range, and that varies depending on the country and the radio frequency spectrum available on a per country basis, I claim the range is about 10 kilometers, and speeds of approximately 70 Megabits a second depending on the antenna. I'm in Santa Clara, California, outside Intel's headquarters. It's what you'd call a liberated building, there's a Wi-Fi signal in every floor, you don't have to stay in your office to get onto the network. The trouble is when you go outside. Here we are in the parking lot, and in fact, I can still get a signal, it's a secure networks icon hack-in, but let's see what happens if I walk a little bit further away. I've now walked to the far side of the parking lot, and I guess some about 500 feet from the building, and there it is I've lost the signal. The problem is how do you get those kind of broadband wireless spades out to a large area like this, where many places can't even get DSL? Now, we'd love to get fibre out to every home, but to do that, you have to dig a trench that costs as much as $300 per foot through a busy area. To go 10 miles, could cost you as much as $15 million, there has to be another way. Here's what's now emerging as the solution. This looks like a normal Wi-Fi access point. Actually, this from Aperto networks is an early version of the big brother to Wi-Fi, WiMAX. WiMAX is designed to send a signal a much, much greater distance at even faster speeds than Wi-Fi. So, we're going to take a look at how well this works. To do it, we're going to take a video signal, compress it through this PC, and send the video over IP, and see how far away we can pick up that signal. I'm on a balcony on a house on the far side of San Jose, and my GPS locator here is telling me that I'm 10.2 miles from my WiMAX access point. I'm still getting a good signal. Robert, could you give me a wave? How about that? That's showing up getting about six megabits per second or there abouts, over a distance of 10 miles. That gives us a radius of enormous coverage of course, several 100 kilometers. This technology is still in it's early days, we're going to see a lot of improvements in the next two years. WiMAX is a global standard. That means that companies all over the world are going to be working and improving on the equipment. Right now, we have a line of sight antenna to get this kind of performance. Over the next couple of years, you're going to see equipment that can be installed inside the home without an external antenna. The result is that WiMAX is going to be able to connect up a lot of places that can't get high-speed Internet access. It's going to give an alternative to current technologies like DSL. Homes, buildings, schools, hospitals, all have a new way now of getting new high-speed broadband Internet access through wireless. We've driven our van here, literally to the end of the road in the hills above San Jose. The GPS locator is telling me we're now 12.2 miles from the WiMAX transmitter on the top of the Intel building. We're still getting a great signal, seven megabits in one direction, 1.5 megabits in the other direction. I said earlier on that you're going to see the benefits of WiMAX in urban areas extending DSL cable or fiber, and reaching other areas that can't be accessed. But rarely, this is also the technology that's going to reach the next five billion people. Realistically, there's something in the range of five billion people that will not be able to get onto the Internet via copper or via fiber, this is the way they're going to get access to that technology.
