What is WiMAX architecture?
The WiMAX network architecture defines the system after the air interface to enable a full end to end network to be achieved. In order that elements of network equipment can be used from different suppliers, it is necessary to define the WiMAX network architecture that is common to all WiMAX networks.
What is WiMAX signaling format?
The WiMAX RF signal uses OFDM (orthogonal frequency division multiplex) techniques and the signal incorporates multiples of 128 carriers in a total signal bandwidth that may range from 1.25 to 20 MHz.
What are the basic components of WiMAX?
WiMAX requires two main components to form an operational network:
- Base Station (BS), which can serve as a repeater or can be connected to the Internet backbone.
- Subscriber/end user, enjoying broadband wireless access through the base station.
What is the length of a frames in WiMAX frame structure?
There are four FFT sizes supported in the 16e standard viz. 2048,1024,512 and 128.

What is WiMAX PPT?
WiMAX is a digital wireless data communication system that can deliver high-speed broadband services up to a large distance of 50KMs. The name WiMAX was created by WiMAX forum, the consortium promoting this standard. The term WiMAX is derived from the phrase Worldwide Interoperability for Microwave Access.
What are the two parts of WiMAX system?
Typically, a WiMAX system consists of two parts:
- A WiMAX Base Station: Base station consists of indoor electronics and a WiMAX tower.
- A WiMAX Receiver – The receiver and antenna could be a stand-alone box or a PCMCIA card that sits in your laptop or computer.
How many subframes are in a frame?
ten
Each frame is divided into ten equally sized subframes. The duration of each subframe is 1 ms. Moreover, each subframe is further divided into two equally sized time slots, that is, each slot is 0.5 ms. 3GPP defines two types of frames based on the duplexing scheme used.
What is WiMAX PDF?
WiMAX provides wireless data transmission using different transmission. modes, from point-to-point to complete cell access. The standard was created in 2001 by the collaboration of Intel and. Alvarion companies and ratified by the IEEE under the name IEEE- 802.16.
What is the difference between Wi-Fi and WiMAX?
Wifi is used to create small networks and used to connect printers, conmputers, gaming consoles. WiMax uses spectrum to deliver connection to network. WiMax is used to provide internet services such as Mobile Data and hotspots.
What are the three types of topologies supported by WiMAX?
3.7 WiMAX Topologies
- PMP (Point-to-Multipoint) topology (see Figure 3.5); Figure 3.5: PMP topology. Figure 3.6: Mesh topology. The BS is no longer the centre of the topology, as in the classical PMP mode.
- Mesh topology or Mesh mode (see Figure 3.6).
What is the purpose of a subframe?
The purpose of using a subframe in an automobile is to distribute high local loads over a wider area of the body structure (most relevant in thin-walled monocoque body designs) and to isolate vibration and harshness from the rest of the body. The subframes are bolted or welded to the vehicle body.
What is LTE frame structure?
In LTE, DL and UL transmissions are organized into radio frames of 10 ms each. Each frame is divided into ten equally sized subframes. The duration of each subframe is 1 ms. Moreover, each subframe is further divided into two equally sized time slots, that is, each slot is 0.5 ms.
What are the advantages of WiMAX?
Advantages of WiMAX :
- A single location can serve hundreds of users.
- Single WiMax BS serves hundreds of users.
- Much faster deployment of the new user as compared to wired networks.
- It creates a volume opportunity for silicon suppliers.
- The speed of 10 Mbps at 10 kilometers with a line of sight.
How does WiMAX operate?
WiMax operates over radio waves on a tower-receiver model. A single WiMax tower can provide coverage over about 8,000 square km (3,000 square miles) and also connect to other towers via a line-of-sight microwave link to broaden coverage further.
Is WiMAX line-of-sight?
While many technologies currently available for fixed broadband wireless can only provide line of sight (LOS) coverage, the technology behind WiMAX has been optimized to provide excellent non line of sight (NLOS) coverage.
What frequency is WiMAX?
WiMAX mainly operates in two frequency ranges. One is high frequency, which is between 11 – 66 GHz and another one is low frequency, which is sub 11 GHz [3]. Line-of-sight is very essential when operating in the high frequency range. This frequency range allows this wider channel, resulting in very high capacity links.
What are the two types of connections supported by WiMAX?
A WiMAX tower station can connect directly to the Internet using a high-bandwidth, wired connection (for example, a T3 line). It can also connect to another WiMAX tower using a line-of-sight microwave link.
