The technical
Seizing the salient points that are at this article, we can say that WiMAX is an "evolution" of the WIFI that is designed to connect large distances between them and overcome the various obstacles. The WIFI instead is designed for offices, housing, etc.., In short, short distances. However, it is possible, of course, a WiMAX network to connect to a wireless network. The WIMAX
to transmit data will not need the sight, that is, if there are trees, houses and anything else of half the transmission is always possible.
" Technology supports a shared data transmission speeds up to 70 Mbit / s in metropolitan areas, using technology that does not require line of sight between the stations. According to WiMAX proponents of this bandwidth is sufficient to support at least 40 companies simultaneously with T1-type connectivity and 70 homes with DSL connectivity to the level of 1 Mbit / s. "
The piece above means that the maximum speed, adding the traffic of all users (whether they are business consumer), is 70 Mbit / s. In fact, after states "According to the proponents of WiMAX this bandwidth is sufficient to support at least 40 companies simultaneously with T1-type connectivity and 70 homes with DSL connectivity to the level of 1 Mbit / s "
WIMAX technology can work on both frequencies for which a license is up for those that do not need. I found a wonderful article on howstuffworks.com that explains everything in simple terms.
"In simple terms, WiMAX would operate in a manner similar to WiFi but at higher speeds over long distances and for a greater number of users. WiMAX could potentially erase the blackout (the lack of access to the Internet, ed) in rural and remote areas that do not currently have access to broadband internet because the phone companies and those Cable does not yet have the necessary wires to those remote places. A WiMAX system consists of 2 parts.

-
A WiMAX tower, which is similar in concept to a tower deicellulari. A single WiMAX tower can provide coverage for a very wide area, large 8000 square km approximately.
-
A WiMAX receiver - The receiver and antenna could be a small box or PCMCIA card (such as those that bring in laptops to connect to the Internet editor's note) or may be integrated into a laptop as is WIFI access today.
A WiMAX tower can connect directly to the Internet using a broadband connection via cable (for example, a T3 line). It can also connect to other WiMAX tower to use a microwave link with sight. This connection to a second tower (often referred to as backhaul), along with the ability of a single tower coprirefino to 8000 square km, is what allows WiMAX to provide coverage to remote rural areas.
What this points out is that WiMAX actually can provide two forms of wireless service.
- There is the type of service without visibility optics, a kind of WIFI service, where a small antenna on your computer connects to the tower. In this mode, WiMAX uses a lower frequency range - 2 GHz to 11 GHz (similar to WiFi). The shorter wavelength transmissions are not easily disrupted by physical obstructions, are better able to diffract, or bend around obstacles.
- There is the type of-sight service, where a satellite dish pointing straight at the WiMAX tower on top of a roof or a pole. The connection-sight is stronger and more stable and thus is able to send lots of data with fewer errors. Broadcasts -sight use higher frequencies, with ranges reaching a possible 66 GHz to higher frequencies, there is less interference and lots more bandwidth.
Health Effects
To summarize what I found on sites such as Timesonline, BBC, etc.. at present there are no studies that demonstrate 100% correlation between the effects of various health and mobile phones, WIFI, microwave ovens, ecc.Non There are, however, even studies that show 100% otherwise. Currently, if we were to say that we could give a percentage to 50%, probably, all these waves are responsible. But let us remember that we are already surrounded by waves (television, radio, mobile phones, microwave ovens, computers, etc.) and that the waves of WIFI - WIMAX are much weaker than those used for cellular repeaters. So it would be wise, in a not far future it is hoped, replace conventional antennas for mobile WiMAX with those. Also because a WiMAX antenna from what I read it cover distances greater than those that the antennas' traditional "reach.
Why I believe WIMAX is important that the
believe that WiMAX is a technology that will revolutionize the future. The literature now also considers ovens, refrigerators, air conditioners as devices that can potentially be connected to the network, as well as mobile phones, smartphones, PDAs (personal data assistant), ecc.Già some implementations are available today, we have the first WiFi phones, the most we can say the iPhone is popular, but there are other open source software solutions that mount as OpenMoko.Contestualmente, Microsoft and other companies are pushing surface on the computer. All these devices will be connected wirelessly. And WiMAX will allow other operators to acquire efficient connections, overcoming the resistance of these possible because of the cost of connections, even in those areas not reached dall'ADSL. WiMAX will allow us to connect to the Internet wherever we want, we can finally connect to the university even with our computer. In my university education is only an island with four computers where you can stay only for a certain period. The wireless connection is not all x, because, probably fearing that students from discharging programs P2P.Con the WIMAX we can call anywhere, using voice over IP. Calls practically exploit the Internet to reach the destination. This can be done today with a computer, but in the future, it can be dealing with a "phone" will allow us to reduce costs of mobile telephony. On the iPhone is already possible to install Skype from what I know. Ergo you can call it "the cell" around the world at local rates and you can call other Skype users for free as it does from casa.Il WIMAX can really become the engine of a new economy and may set the tone for a new type business.Bon of, I think I've said everything there was to say. I wait for a response from the Meetup Grillo.
