Being connected to the Internet with excellent data transmission speed is what we all look for, and that can be offered by the new technology, known as WiMAX . We can enjoy with this type of connection new features that will improve our experience as a cybernet.
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 right now.
Although it is not enough to emphasize, before starting that this connection is much faster than the one reached, when we use a satellite Internet connection.
What is WiMAX and what is this wave Internet technology used for? radials?
WiMAX is the new technology that allows us a greater Internet connection with a better speed, greater than that offered by Wifi. This signal is propagated by microwave , obtaining a range greater than 30 km , with a data upload and download speed of 124 Mbps .
Up to now, Wifi offers a maximum speed about 54 Mbps with a maximum coverage of 300 meters . WiMAX connections are very similar to those of an ADSL (acronym for Asymmetric Digital Subscriber Line, whose translation is Asymmetric Digital Subscriber Line).
The name WiMAX comes from the acronym Worldwide Interoperability for Microwave Access, which in Spanish means World Interoperability for Microwave Access, just like Wifi does not need a wired connection , and its base can support hundreds and hundreds of subscribers, for each one.
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 you need electronic devices and a tower called WiMAX Base Station. The tower works just like the towers of network telephones, which are located at a high point of it, so that the signals can be emitted with greater amplitude.
These signals are very much compared to radio waves , because they are transmitted at a certain frequency. This antenna can cover a radius of more than 30 km in the round, this being a good advantage that attracts more and more users every day.
This wireless connection is compatible with any device (computers, laptops, smartphone, 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 card >, whose function is to adapt frequencies for laptops or computers, and the connected device are computers or phones.
Relatively the WiMAX connection works almost the same as the Wi-Fi 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 at a frequency of 2.3 to 3.5 GHz . This technology is known as last mile technology or local loop, is defined by the IEE 802.16 standard .
For this technology to work properly repeater antennas (microbases) are needed which are strategically placed to provide services in specific areas. It has a central antenna that communicates with the subscribers’ antennas, which is known as a transceiver .
What types of WiMAX exist and how are they different? / span>
Wireless networks WiMAX are divided into two types, such division differentiates the types of equipment that will be connected to them:
WiMAX Fixed
This type of WiMAX 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 Fixed , named in this way because an antenna is located in the upper part of the house (mostly users locate it in their rooms), which is considered as the perfect place for the good distribution of the waves.
This type of WiMAX Fixed is the wireless solution for broadband Internet access . Where it can also be used at its maximum speed of 5.8 GHz (license free).
WiMAX Mobile
This type of WiMAX is a revision of its IEEE 902.16.2004 standard, generating the IEEE 802.16e with a focus on the mobile market, adding portability as the main function. Devices that are equipped with this standard use the Orthogonal Frequency Division Multiple Access (OFDMA) very similar to OFDM, in which they are divided into multiple carriers.
As we saw, are two types of WiMAX connections that work for different sides. In summary we can say that the Fixed standard 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 features of a radio wave internet connection? ?
Being able to connect to the Internet through WiMAX brings many benefits. These are essential features of it.
Here is a small list of the most important features of this connection:
- We can enjoy a connection with distances greater than 70 km , thanks to very directional or high-gain antennas.
- Thanks to its frequency distribution, we can enjoy a browsing speed of up to 75 Mbps, 35 + 35 Mbps , provided the spectrum is clean.
- It gives us the facility to add more channels, although this is going directly related to the regulation of each country.
- A bandwidth of configurable band and not closed , always related to the spectrum.
- Divide the communication channels in small carriers (In Guardians and in Data).
WiMAX vs Satellite Internet Which is better to have 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 is established through a telephone line , where in many cases we must install a satellite dish. You must comply with the mini power cycle so that the data can be transmitted.
The cycle that must be fulfilled is the sending of the signals, whose means of transport can be a cable or a modem that transforms the connection into a wireless signal. Satellites send and receive all data, that is transformed by a device (router).
When a signal is sent to a satellite with a distance greater than 36000 kilometers, there is a delay for the transmission of data and the return of them, this is known as ping or lag that It 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.
Now that we know what is the Satellite Internet and also knowing what WiMAX is, we can conclude the following:
- WiMAX offers a faster connection than the satellite Internet , because 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 the satellite Internet, in addition that its costs are lower
How fast can the Internet be through radio waves?
WiMAX belongs to the new era of Internet connection. Thanks to its signal propagation technology we can enjoy fast navigation, so much that there can be 100 users connected simultaneously and it would not affect the speed with which the data is transmitted.
>
Thanks to the fact that it covers a greater range we can enjoy it wherever we want, and the best thing is that its signal can offer us excellent connection speed , as long as we are within the determined range. Its speed can yield even greater than 70 Mbps, with a frequency greater than 3.5 Hz.
