Use the pretty hair extensions styling spray as a good helper. The finished styling volume doesn't have to worry even if it clip in hair extensions rains. If you are a short-haired little fairy, you want to make the hair wigs overall shape a little more playful. You can also try to add a buckle to the remy hair extensions end of the hair like the B-station up to the main meter.

Amimon takes $15 million to push the non-WiFi ticket, in WiFi’s space

The world loves a trier and Israeli’s Amimon is certainly not about to give up its bid to be the de facto video chip player in wireless HD devices around the home, and has just won another $15 million to push its WHDI chip sets.

When we were at IP&TV World Forum this week people asked about WHDI and it’s easy to get confused between this and 5 or 6 other players who are pushing the envelope on wireless connection of HD video signals. WHDI uses the same unlicensed 5GHz spectrum which has been released for WiFi in most countries, whereas SiBEAM and WirelessHD uses 60GHz spectrum and competes head on with WiGig, and in fact SiBEAM, has created a chip which offers both WirelessHD and WiGig in one.

Our money is on pure WiFi and talking to Celeno and Airties at the show, it’s what works today. The tough decisions ahead are which platform to use as a backbone for an increasingly besieged home network. As Tablets proliferate and WiFi signals are needed crystal clear in the living room, and need to be HD capable, the looming 802.11ac standard looks favorite, and companies like Quantenna, Celeno and Airties can all hop to that standard more or less unchanged.

The fight for a home backbone may be between coaxial cable, twisted pair and power cables, and there may be a different winner on each continent, but we can’t help think they are playing for a smaller piece of the pie, once wireless signals within a room become resolved for carrying HD. At the show, pure 1901 powerline looks like it is claiming 500 Mbps, is only admitting to 300 Mbps usable on its wireline portion (1 Gbps over the rest of its architecture) and that leaves the door ajar for the preferred MoCA connectivity used for multi-room DVRs in the US to take the bandwidth high ground in a bid for the home backbone, but not actual device connectivity, at least not in Europe where there is so little coax.

But as 5 GHz signals are unlicensed and clear for use, that seems a place we can see for the near future wireless standard and using 20MHz WiFi channels, or bonding them to 40 MHz channels or including smart MIMO antenna and using channel hopping to ensure the best channel is used for a signal all the time, are all common techniques for everyone – the difference is that if your technology can ONLY be used on your chips, then every home still needs to have WiFi in there somewhere. We think 60 GHz is a science project at the moment and success for it is down the line somewhat, if ever.

And that’s the problem that Amimon seems to have. It says that it is going to use this new $15 million to create follow-on generations its WHDI chipset, and that these will be used to offer wireless HDTV and PC-to-TV and mobile and tablet-to-TV connections. Amimon said that numerous companies are developing products (wireless HDTVs, PC-to-TV, tablet-to-TV, HD Wireless Bridges) based on WHDI chipsets.
