This report addresses technologies and markets for home/office (“local”) distribution of bandwidth-intensive signals. Related applications that require QoS support and demand the rate of transmission from several Mb/s and up to several Gb/s became typical for current HDV, IPTV and similar signals distribution. These applications are opening the multi-billion market for manufacturers of related ICT devices; they also intend to satisfy the growing users' demand for home/office interconnects.
Two major types of communications channels in the converged LAN/PAN environment are:
Both compressed and uncompressed transmission of HDV and similar signals is considered.
This report reflects dynamics of LAN/PAN markets and technologies for “local” distribution of bandwidth-intensive signals with an emphasis on recent advances; and, particular, it analyzes:
UWB WPAN. The UWB industry is suffering from a severe downturn. Several companies went out of business; other changed their profiles or merged.
In the analyzed time period, the UWB WPAN market will show little progress. It seems, though, that such a downturn will not last long. There are indications of the regulatory stabilization (the FCC, in 2010, reaffirmed the UWB rights on existence - ET Docket No. 98-153 and ET Docket No. 04-352; effective by November 12, 2010); EU supports several UWB projects based on participation of leading vendors and research organizations. UWB value for WPAN is clear; and this technology will be given more opportunities to prove its place in the WPAN development.
Visible Light Communications (VLC). The report addresses the emerging VLC technology as one of potential leaders in the WPAN development with a wide range of characteristics suitable for variety of applications. The technology is still in the standardization stage (IEEE 802.15.7 and other). The VLC communications channel can be extended to several kilometers (with Kb/s speed); and it supports communications with the speed of several hundreds Mb/s at the shorter distances (4-10 meters). Its most attractive feature is that VLC, in many cases, can be built on the existing illumination infrastructures (for example, modulating LEDs.) Due to the fact that solid state lighting devices will prevail as a source of light in near future, office buildings, rooms, cars and other can use such added-value communications. First commercialized VLC products are expected in 2012-2014.
60 GHz radio. The report analyzes WirelessHD - IEEE 802.15.3c, ECMA and WiGig developments. The technologies may have a different basis (for example, WiGig is an extension of Wi-Fi), but all of them are united by the fact that they can support several Gb/s communications between CE devices that transmit uncompressed HD V/A. There are first commercial WirelessHD products on the market; with WiGig prototyping. The market is expected to reach sizable volume in 2012-2013.
WHDI (Amimon). WHDI is another wireless technology to build bandwidth-intensive WPANs. These radios explore the 5 GHz band; and use sophisticated encoding of HD V/A signals. The WHDI products are in a market starting from 2008; there are multiple examples of cooperation between Amimon and CE vendors. As the company stated, the technology can support communications between CE devices located anywhere in a house.
HomePlug. Current developments in this technology (HomePlug AV2) allow enhancing of bandwidth-intense applications based on the utilization of home electrical wires. It extends coverage and allows higher speeds of transmission than previous standard options.
Home PNA-ITU. These standardization efforts lead to the development of the “universal” technology that can utilize any type of home wiring (phone, coax, electrical). So far, there is a mixed reaction in the industry to this development. 2010 was a year of ratification of several standards from this group.
MoCA. This technology also continues its evolution. MoCA 2.0 (ratified in 2010) offers two new performance modes with actual throughputs of 400 and 800 Mbps, respectively, each with a corresponding turbo mode. Also, two new lower power modes increase energy savings (sleep and standby).
HDBaseT, DiiVA, and DisplayPort technologies and related markets reflect the user demand for multi-gigabit-per-second transmission with the goal to support uncompressed HDV and similar signals distribution among multiple CE devices in the home/office environments.
The report goal was to objectively reflect multiple industry initiatives that address users' requirements for distribution bandwidth-intensive signals in LAN/PAN environments. The industry and related markets are segmented by the technology type; demand on HD and similar CEs makes the LAN/PAN market an attractive choice for many manufacturers.
