A new Wi-Fi standard that promises speeds sometimes breathtaking. In the meantime, follow our tips to make the most of your home network.
Go! Wi-Fi or 802.11 ac fifth generation is in the starting blocks. The first compatible hardware routers and end were presented in May 2012 in Monaco, at the show that brings MedPi manufacturers and vendors and they would be marketed this summer.

Wi-Fi ac promises to be much faster than its predecessor, Wi-Fi n. It is supposed to deliver a maximum bandwidth of 1.3 Gbit / s while its predecessor caps today to 450 Mbit / s. Of course, we are talking about theoretical throughput because the reality is probablementmoins glorious.
Wi-Fi n to 300 Mbit / s does he not the best actual throughput of 100 Mbit / s? So, count on us to measure the true performance of Wi-Fi action as soon as possible! One reason for optimism is that it will finally abandon the frequency band of 2.4 GHz exploited by other standards Wi-Fi (IEEE 802.11b, g and n) and the more saturated it is also used by other devices (cordless phones, wireless controllers, baby monitors ...).
Wi-Fi uses ac him, only the 5 GHz band benefiting from additional non-overlapping channels 23, almost eight times more than the Wi-Fi n.
But do not worry: who can do more can do less! You can use your existing hardware routers with Wi-Fi ac: they also work on the 2.4 GHz band for reasons of compatibility. Flows will be just limited to a maximum throughput of 450 Mbit / s Wi-Fi n.
Another advantage of this standard is to concentrate the signal to devices on the network instead of radiating in all directions. We should therefore see an improvement even staying in Wi-Fi mode n. A priori not worry about the compatibility between the first material and the following ac 802.11.
The framing of the standard is well advanced and it should be ratified by the IEEE in early 2013. She will not know the woes of Wi-Fi n that, he was not finalized until two and a half years after the release of the first products.
But what can these outlandish rates?
First eliminate the bottleneck that can represent the Internet box (or router). Even Wi-Fi, watching the saturation from three simultaneous connections, a condition more common given the number of devices that may be connected to our home network computer, printer, game console, smartphone, tablet, TV, media gateway ... And also to enjoy a comfortable speed when it moves away from the source.Until this new Wi-Fi is widespread and it integrates the box of our service providers (ISPs), the many tips in this folder will already be put into practice to push the boundaries of your home network.
Rates of different tech
| STANDARD NETWORK | RATE THEORETICAL / ACTUAL MAX. | RECOMMENDED USE | |
| G WI-FI | 54 MBIT / S | 25 MBIT / S (3.1 MB / S) | SURFING |
| WI-FI N | 300 MBIT / S | 100 MBIT / S (12.5 MB / S) | HD VIDEO, SURF |
| WI-FI AC | 1.3 GBIT / S | FORTHCOMING | MULTI-SCREEN VIDEO, VIDEO GAMES, SURFING |
| CPL 85 | 85 MBIT / S | 21 MBIT / S (2.6 MB / S) | SURFING |
| CPL 200 | 200 MBIT / S | 72 MBIT / S (9 MB / S) | HD VIDEO, SURFING, VIDEO GAMES |
| CPL 500 | 500 MBIT / S | 232 MBIT / S (29 MB / S) | MULTI-SCREEN VIDEO, VIDEO GAMES, SURFING |
| FAST ETHERNET | 100 MBIT / S | 88 MBIT / S (11MB / S) | HD VIDEO, SURFING, VIDEO GAMES |
| GIGABIT ETHERNET | 1000 MBIT / S | 640 MBIT / S (80MB / S) | MULTI-SCREEN VIDEO, VIDEO GAMES, SURFING |
Initial advice
1 - To give a boost to your home network router choose power run last generation, Wi-Fi n and Gigabit Ethernet. The box of your ISP will no longer serve as Internet modem (DSL, cable or fiber).
2 - To transmit the video signal in the channel without interference or galleys configuration, go through the electrical outlets in your installation (CPL).
Health: waves under surveillance
The impact of electromagnetic fields on health is the subject of numerous studies and those of Wi-Fi do not escape. They have been evaluated and, according to the World Health Organization, prolonged exposure to waves of Wi-Fi without risk to health. Indeed, there is, to date, no scientific evidence confirming potential harmful effects of wireless networks. But as a precaution, the Wi-Fi networks have been officially banned in schools in England, Germany and Austria. Our common sense advice: Avoid placing your box or your Internet router on your bedside table or in the childrens room ...
