Wi-Fi Home Networks Enable HD Video Distribution

The digital home Local Area Network (LAN) will increasingly become instrumental in enabling HD video distribution within a residence, and in particular emerging over-the-top (OTT) video entertainment services.

Wired Ethernet is still the preferred method to interconnect devices on the network, such as broadband routers and digital media player set-top boxes. However, in larger homes there are times where using Ethernet cables isn't practical. Most consumers attempt to use Wi-Fi routers to provide wireless connectivity.

Using a legacy Wi-Fi router to stream HD video can be problematic, because high-definition video requires greater bandwidth. New high-speed gigabit routers are therefore becoming the preferred wireless home networking standard.

2009 was a premier year for the latest Wi-Fi standard, 802.11n. The current 802.11n devices showed significantly stronger growth than 802.11g, according to the latest market study by In-Stat. 802.11n grew 76 percent year-over-year -- compared with an annual decline of 14 percent for 802.11g.

"The wireless LAN (WLAN) market continued to grow in 2009, despite the decline of the worldwide overall market," says Vahid Dejwakh, In-Stat analyst.

In-Stat's market study found the following:

- Worldwide revenue was up 5.2 percent in 2009 compared with 2008.

- NETGEAR and D-Link took the lead in WLAN shipment market shares, at 23 percent and 18 percent respectively.

- 68.5 million WLAN units shipped in 2009.

- Small Office Home Office (SOHO) router revenues increased to $1.16 billion in 2009.

- North America accounted for 46 percent of all WLAN shipments in Q409.

Trillion-Dollar Smart Power Grid Transformation

The global energy landscape is undergoing a significant transformation. Renewable energy sources like solar and wind are rapidly gaining ground as we transition towards net-zero emissions. However, this transition hinges on a crucial but often overlooked factor: the modernization and expansion of our aging power grids across the globe. For decades the backbone of our electricity delivery system has been largely static. The influx of variable renewable energy sources like solar and wind presents a new challenge. Smart Power Grid Market Development Integrating these resources effectively requires a Smarter, more Responsive grid that can handle fluctuating power generation and efficiently distribute it across vast distances. This is where a new trillion-dollar energy market growth opportunity emerges. According to a recent worldwide market study by ABI Research, global investments in public grid digitalization and transmission network expansion must exceed $4 trillion by 2030 to meet our
