Being connected to the Internet with a excellent data transmission speed It is what we are all looking for, and that can be offered to us by new technology, known as WiMAX. We can enjoy new features with this type of connection that will improve our experience as a netizen.
You may wonder: What is it? how does it work? why is it so fast? And to please you, we leave you the answers to all those questions that are going through your head at this moment.
Although it is worth emphasizing, before beginning that this connection it’s much faster than that achieved when we use an Internet connection via satellite.
What is WiMAX and what is this radio wave Internet technology used for?
WiMAX is the new technology that allows us a greater connection to the Internet with better speed greater than that offered by Wifi. This signal is propagated by means of microwaves, obtaining a range greater than 30 kmwith a data upload and download speed of 124Mbps.
Until now the Wifi offers as maximum speed about 54 Mbps with a coverage of 300 meters at most. WiMAX connections They are very similar to those of an ADSL (acronym for Asymmetric Digital Subscriber Line, whose translation is Asymmetric Digital Subscriber Line).
The WiMAX name stands for Worldwide Interoperability for Microwave Access, which in Spanish means World Interoperability for Microwave Access, just like Wifi no need for a wired connectionIn addition, its base can support hundreds and hundreds of subscribers, for each one of them.
How does WiMAX work?
Its operation is simple, as its name indicates. Signals are transmitted from the base to the destination point. To make it work need electronic devices and a tower called WiMAX Base Station. The tower works the same as network telephone towers, which are located at a high point of it, so that the signals can be broadcast more widely.
These signals are very much compared to radio waves, because they are transmitted at a certain frequency. this antenna can cover a radius greater than 30 km around, this being a good advantage that attracts more and more users every day.
This wireless connection is compatible with any device (computers, laptops, smartphones, Android…).
The destination point of the WiMAX signal is divided into two: Receiver point, and connected device, where the receiver is a separate antenna device or a PCMCIA slot cardwhose function is to adapt the frequencies for laptops or computers, and the connected device are computers or phones.
Relatively, the WiMAX connection works almost the same as the Wifi connection, although the only difference is that WiMAX can cover a larger area, thanks to its microwave propagation technology.
At what frequency is the data transmitted?
The data is transmitted to a frequency from 2.3 to 3.5 GHz. This technology is known as last mile or local loop technology. is defined by the IEE 802.16 standard.
For this technology to work properly repeater antennas (microbases) are needed which are strategically located to be able to provide services in certain areas. It has a central antenna that communicates with the subscriber antennas, which is known as a transceiver.
What types of WiMAX are there and how are they different?
wireless networks WiMAX are divided into two types, this division differentiates the types of equipment that will be connected to them:
Fixed WiMAX
This type of WiMAX It is designed under the IEEE 802.16-2004 standard, to allow fixed access. When we talk about fixed access we refer to a kind of Wireless Landlineso named because an antenna is placed on the top of the house (Mostly users place it in their rooms), which is considered the perfect place for the good distribution of the waves.
This type of Fixed WiMAX is the wireless solution for broadband Internet access. Where you can also use your maximum speed of 5.8 GHz (licence-exempt).
Mobile WiMAX
This type of WiMAX is a revision of its IEEE 902.16.2004 standard, generating IEEE 802.16e with a focus on the mobile market adding portability as the main function. Equipment that is equipped with this standard uses the Orthogonal Frequency Division Multiple Access (OFDMA) very similar to OFDM, in that they are divided into multiple carriers.
As we saw, there are two types of WiMAX connections They work for different sides. In summary we can say that the Fixed standard It is for an area delimited by a frequency emitted by an antenna, while the mobile is a function of mobile devices.
What are the main characteristics of a radio wave internet connection?
Being able to connect to the Internet through WiMAX brings many benefits. These are essential characteristics of it.
Next, we show you a small list of the most important characteristics of this connection:
- We can enjoy a connection with distances greater than 70 kmthanks to very directional or high-gain antennas.
- Thanks to its frequency distribution, we can enjoy a browsing speed of up to 75Mbps, 35+35Mbpsas long as the spectrum is clean.
- It gives us the facility to add more channels, although this is directly related to the regulation of each country.
- a width of configurable band and not closedalways related to the spectrum.
- Divide the communication channels into small carriers (In Guards and in Data).
WiMAX vs. Satellite Internet Which is better to have a connection in rural areas?
In order to make a comparison of the WiMAX Internet connection with the Satellite Internet, we first need to know what the satellite Internet is. Next, we will see a brief description of this type of connection:
satellite internet
This is a type of connection that established through a telephone line, where in many cases we must install a satellite dish. Must comply with power minicycle for data to be transmitted.
The cycle that must be completed consists of sending the signals, whose means of transport can be a cable or a modem that transforms the connection into a wireless signal. The satellites send and receive all the data, that are transformed by a device (router).
When a signal is sent to a satellite with a distance greater than 36,000 kilometers, there is a delay for the transmission of data and the return of them, to this it is known as ping or lag which can be much higher (up to 10 times higher) than ADSL and also higher than WiMAX, so if we are going to play online, watch video conferences or watch HD video, this is not favorable at all.
Now that we know what is Satellite Internet and also knowing what is WiMAX we can conclude the following:
- WiMAX offers a faster connection than satellite Internetbecause its transmission is by waves.
- If we talk about ease of connection, with WiMAX we can obtain it, thanks to its control minibases or wave repeaters.
- With WiMAX we can enjoy a greater range than satellite Internet, in addition to its costs are lower
How fast can the internet be over radio waves?
WiMAX belongs to the new era of Internet connection. Thanks to its signal propagation technology we can enjoy fast browsing, So much so that there can be 100 users connected simultaneously and it would not affect the speed with which the data is transmitted at all.
Thanks to the fact that it covers a greater range, we can enjoy it wherever you want, and the best thing is that its signal can offer us a excellent connection speed, as long as we are within the determined range. Its speed can perform even higher than 70 Mbps, with a frequency greater than 3.5 Hz.
