Nowadays, most tablets, smartphones, ultrabooks and TVs launched are connected to the home in one way or another. This is possible through home networking technologies that are constantly being developed. Contrary to popular belief, WiFi is not the only main wireless technology available in one’s home. Those presented below should be considered and even more evolution is expected in the future.
Different forms of WiFi are included in almost all mobile and some stationary devices. Home networks can easily connect to it, with the fastest and latest version being based on IEEE 802.11 ac specification, which should appear on most modern tablets and phones in the near future. The modern technology is capable of working perfectly in homes even through tougher elements like brick retaining walls. Broadcom declared that the new WiFi 802.11 ac chips will be available for the smaller gadgets soon and will be capable of running at 300M bps. Routers and laptops using the technology are already available.
Wireless Gigabit Alliance is now pushing WiGig technology, a rather new system that uses the barely used, unlicensed spectrum in 60 GHz range. Such frequencies cannot travel far but the technology connects to nearby things, building the network point to point. As an example, a light computer can be connected to a monitor and its peripherals without the use of other connections. This technology can also send HD video streams for gaming or viewing on a TV, reaching top speeds of around 7G bps. Specialists believe speed can go even higher.
We already see WirelessHD included in adapters used for various equipment, like home theaters and projectors. The top theoretical speed is 28G bps, with a new chip designed for tablet and smartphone use being developed right now. New technology is capable of receiving and sending video at a resolution of 1080p and with multi-channel audio towards portable devices or big screen TVs.
This is an interesting set of technologies that can transmit data over a home’s electrical wiring. It can act as the network backbone, reaching gaming consoles, tablets, TVs and various other devices through Ethernet or WiFi. An adapter is plugged into the wall socket and the connection is created. Gigabit-class speeds are already available, being able to transmit HD video streams. AV2 is now included in a chipset that was already shipped to different manufacturers as samples. The HomePlug AV2 chipset gives access to over 500M bps.
MOCA (Multimedia Over Coax Alliance) offers a technology that can be used in home networks through coaxial cables sprouting from North American homes. Coax is fundamental in cable TV technology. MOCA 2.0 is perfect to distribute videos all around the home, reaching a maximum speed of 400M bps or 800M bps in a special Enhanced Performance Mode. UltraHD video can be transmitted from a set-top box to another one. MOCA has been in direct competition with HomePlug but these are 2 different technologies that have different uses. HomePlug uses electrical sockets and MOCA focuses on reliability through coax cables.
