How WiMAX Wireless Internet Works
With Customer Provided Equipment
How WiMAX works:
WiMAX Internet is an important step in the future of global Internet communications, and while the whole world was just getting warmed up to WiFi Technology it’s time to take a step back and look at WiFi’s closest companion WiMAX.
If you haven’t been asked yet what is WiMAX, then you might want to prepare yourself with an educated answer, since this new and upcoming technology isn’t going away and will soon eclipse WiFi hotspot locations.
WiMAX stands for Worldwide Interoperability for Microwave Access, and it’s not just the name that’s big. WiMAX Interoperability can provide WiMAX Internet access at ranges that WiFi will only dream about, and we’re here to discuss how WiMAX works to make that all happen.
The WiMAX Internet solution is WiFi on a colossal scale.
While WiFi uses a Wireless Router Repeater to expand its wireless coverage area.
WiMAX uses cells of fixed and mobile towers called “Base Stations”.
These cells are the infrastructure, and is what we’ll be discussing so you understand how WiMAX works.
How WiMAX Works
To answer what is wimax, we’ll be covering in more detail how WiMAX works from WiMAX access point to WiMAX Internet, so you can visually perceive how it all works following your data from source to destination.
Where the WiMAX Spectrum really comes into its own is in its proficiency to pass data between WiFi and WiMAX cells, and it’s this interoperability that gives WiMAX Internet its captivating appeal.
We’re going to start at the user end of the voyage at the WiMAX access point, and carry you through the process as packets are routed through a mesh network of WiMAX towers, and passes into the ISP network on a backhaul and out to the Internet.
WiMAX Portals: (Customer Provided Equipment)
Our journey begins here with WiMAX CPE or Customer Premises Equipment.
CPE, which is basically just an acronym for Customer Provided Equipment that is any device or equipment that will allow you to communicate and gain access to a WiMAX access point. There are both indoor, and outdoor WiMAX CPE devices depending on location.
A WiMAX CPE could be a Wireless USB modem, laptop with an Intel Centrino chipset with WiMAX capability, an MRT Mobile Radio Transmitter for your vehicle, and of course a WiMAX subscriber unit for home or office WiMAX Internet services and is how WiMAX works on the subscribers side of the service.
WiMAX subscriber units can either be indoor or outdoor depending on the distance to the nearest WiMAX base station tower, and if there are obstructions within the subscribers service area. These WiMAX access point devices are what is WiMAX version of a Cable Modem Wireless Router or DSL Modem Wireless Router depending on what you’re used to.
When needed (SU-O) subscriber unit outdoor antennas can be mounted and connected by cable to (SU-I) subscriber unit indoor devices to providing stronger signals inside the customer location when tall buildings or trees restrict signals from the local service towers.
WiMAX Towers: (Fixed and Mobile Towers)
How WiMAX works and performs as your network packets enter a WiMAX access point really depends on whether you’re in a metropolitan area or rural area.
Fixed base station towers are located in cities, and Mobile base station towers are located in rural areas, which handle subscribers connecting on upgraded mobile towers interweaved through city service areas.
The Fixed towers which are connected with home or office subscriber units, such as a WiMAX Providers supplied indoor or outdoor subscriber unit operate on high power output transmissions providing 3.5GHz signals out to distances of 25 miles when passing through Fixed towers arranged in cells forming a mesh topology.
The Mobile towers accommodate smaller form factor CPE devices such as laptops with WiMAX wireless mini cards, cellular phones, and mobile hotspot devices, and are basically upgraded mobile phone communication towers with added support for fast connection relay between mobile towers as customers are traveling through service areas.
Mobile towers operate entirely different then fixed towers due to handheld devices being limited on battery and processing power. If you’re unsure which towers you’re connecting to, just look at the specifications of your WiMAX CPE device. 802.16d will connect with fixed towers, and 802.16e equipment connects and operates on Mobile towers.
ISP Network: (Backhaul Connection)
Now that your network packet has entered the WiMAX wireless network whether on fixed or mobile towers cells, it’s headed on the shortest path possible to your WiMAX Internet service provider network on a connection known as the “Backhaul”.
Just as your CPE Customer Provided Equipment; whether it be a WiMAX subscriber unit located on or inside your home or a handheld device that connects to WiMAX mobile towers on the front end, your ISP is connected to the WiMAX Fixed and Mobile tower array via the backhaul system.
The backhaul connected to your ISP is like the default gateway address on your local area network. It gives the network packets on the WiMAX tower array a destination address to reach, so they’ll pass through your ISP and out on the Internet.
The WiMAX wireless Internet solution is a very ingenious network topology of mixed telecommunication towers. The tower array not only allows for fixed and mobile communications between subscriber and ISP, but even supports roaming between ISP networks contributing to the term WiMAX Interoperability.
That’s it! We hope you now have better understanding of what is WiMAX, and how WiMAX works to provide Internet access with WiMAX wireless Internet 802.16d subscriber units and handheld 802.16e mobile wireless enabled devices.
