Wireless Data Transmission Speed

Up To 30 Gbps: New Chip Enables Record-Breaking Wireless Data Transmission Speed

It looks like we can expect faster wireless connections in the near future: Japanese electronic parts maker Rohm yesterday announced [JP] it has developed a chip that reached a wireless data transmission speed of 1.5 gigabits per second in experiments, the highest level ever. And according to the company, even 30Gbps will be possible in the future.

The semi conductor device uses terahertz waves for data transmission, has a micro antenna attached to it and is 2cm long and 1cm high (size of the module). Rohm developed the technology in cooperation with a research team at Osaka University.

According to Japanese business daily The Nikkei, Rohm expects the new chip to cost just “several hundred yen” to produce (100 Yen currently translate to US$1.30). By way of comparison: the terahertz-based wireless chips out there now cost “several million yen”, are about 20cm square and reach a top speed of just 0.1Gbps, The Nikkei says.

Understanding website security indicators

See if the site is using a secure connection (SSL)

If you’re entering sensitive personal information on a page, look for a lock icon to the left of the site’s URL in the address bar to see if the site uses SSL. SSL is a protocol that provides an encrypted tunnel between your computer and the site you’re viewing. Sites can use SSL to prevent third parties from interfering with the information traveling through the tunnel.

Icon	What it means
	The site isn't using SSL. Most sites don’t need to use SSL because they don’t handle sensitive information. Avoid entering sensitive information, such as usernames and passwords, on the page.
	Browsers has successfully established a secure connection with the site. Look for this icon and make sure the URL has the correct domain, if you’re required to log in to the site or enter sensitive information on the page. If a site uses an Extended Validation SSL (EV-SSL) certificate, the organization's name also appears next to the icon in green text. Make sure the browser is set to check for server certification revocation to identify sites with EV-SSL certificates.
	The site uses SSL, but browsers has detected insecure content on the page. Be careful if you’re entering sensitive information on this page. Insecure content can provide a loophole for someone to change the look of the page.
	The site uses SSL, but browsers has detected either high-risk insecure content on the page or problems with the site’s certificate. Don’t enter sensitive information on this page. Invalid certificate or other serious https issues could indicate that someone is attempting to tamper with your connection to the site.
