The Future Of Wireless Technology

Nowadays, wireless technologies have caused new transformations in urban mobility and, consequently, new designs in cities such as San Francisco, New York, Paris, London, Seoul and, of course, São Paulo. These enter the age of ubiquitous computing, where you can access what you want, where, when and how you want, through virtualization of information, services and applications. This is with the help of new wireless technologies such as 3G, Wi-Fi, Wi-Max and bluetooth.

The contemporary urban area walks to become a place of permanent connection, allowing mobility and exchange of information anywhere and at any time. In addition, wireless technologies can help the country accelerate digital inclusion projects, especially in areas lacking infrastructure.


There are globally more than 200 million broadband users in all its forms, and the pace of growth presented does not show any signs of cooling, with growth projections to around 700 million in 2008. Of the total current users , it is estimated that two-thirds or more have connections over fixed networks, such as DSL and cable modems. The other accesses are offered by wireless networks, which already have several devices capable of rapid access to data and provide users with the benefits of full or restricted mobility.

A more recent development is the increasingly solid evolution of wireless broadband offerings through 3G solutions as well as “alternative” wireless technologies such as Wireless Mesh (based on the WiFi standard) and WiMax.

As a result of the advancement of these technologies, trends are already beginning to indicate that global growth in the number of broadband users should have a strong wireless component. If today users with high-speed downloads via wireless connections account for less than a third of the total, it is estimated that in 2008 they represent more than half of global users. The reasons for this transformation are the proliferation of the number of wireless broadband networks and devices and the cheapening of the technology in general, due to the growth of its scale.

The Future

Asking for the Wi-Fi password has already become a convention in any visit to family, friends, and also in bars and other places of social interaction. And this will hardly change. With the growing number of devices connected to each network, now that even children and pre-teens also have their cell phones and the internet of things is advancing exponentially, the telecommunications industry has been looking for new avenues for Wi-Fi.

The main recent novelty in expanding the possibilities of the wireless connection is mesh technology. To spread the signal with quality in large environments, it uses several physical devices, which exchange information between themselves and also with the connected devices, in order to define the best specific point of connection for each of them.

Although somewhat similar to signal repeaters, mesh devices are gifted with greater intelligence so that each point on the Wi-Fi “bridge” supplies the other with a larger band, rather than just receiving the one-sided signal coming from the router.

Router manufacturers have been launching their devices with this technology, and also combining it with other possibilities. In the latest case, Samsung has in its new device a mesh connection that uses artificial intelligence to give a greater band to a certain device depending on the flow of data. That is, if someone is watching a high resolution movie on a computer and no one is using the printer connected to the network or the smart refrigerator in the house, the connection automatically privileges the PC that requires a larger bandwidth.

Already in its second attempt at smart routers, the company now licenses the Plume provider’s AI, and combines the novelty with another: a hub so that it can easily manage the various connected devices, from computers and cell phones to appliances and even lamps – a trend that should grow as more and more household objects gain intelligent versions and connect to the internet.

With technology, it is possible for parents to know the time and volume of connections used by their children, for example, and to create temporary passwords so that visitors do not have access to certain resources. They can also remotely unlock doors, turn on the television, and tinker with the air conditioning as long as they are connected to the Wi-Fi.

The possibilities of this new standard of Wi-Fi connection have been attracting companies that, by nature, did not even act in this market. Google itself has entered the wave, with its mesh devices that connect to the router and allow to manage all the details of the connection on the smartphone itself.

A barrier to the spread of technology, however, is the high values ​​- especially if you have a home that will need more than one connection switching point. Both Google and Samsung sell their handsets individually or in packs of three, which cost $ 300.
