At CES, a variety of companies showed Miracast products. Miracast mirrors the display on a phone or tablet on a television. It uses WiFi to transmit the signal to your TV.

Phones like the Nexus 4 support it. To date, more than 200 smartphones, tablets, TVs have been certified by the WiFi Alliance, to support Miracast. All Intel WiDi devices also support the standard. The Wi-Fi Alliance currently has a list of more than 60 certified devices on its Web site.

The Wi-Fi Alliance demonstrated Miracast at CES last week, sending live computer game animation from a smartphone to a 27-in. television. An LG Optimus G smartphone enabled with the Miracast technology to wirelessly send an Angry Birds game from the phone a nearby TV.

Vendors announcing Miracast products included, Netgear, LG Electronics, Sony, Qualcomm, Actiontec Electronics, Advanced Micro Deices, Broadcom, Cavium and Marvell Semiconductor.

LG’s rumored Nexus 5 and Nexus 7.7, slated to arrive at Google I/O this May, may also support Miracast.

Near the Wi-Fi Alliance’s booth, promoters of wired USB connectors showed off their latest innovations.

The USB 3.0 Promoter Group, which already announced 5 Mbps development of SuperSpeed USB, announced a speed increase to 10 Gbps (pdf)– or about double the data throughput over USB 3.0. The 10 Gbps USB 3.0 standard stipulates continued use of the same cables and connectors for higher throughput. There are already more than 720 certified SuperSpeed USB products available, double the number of a year ago.

SuperSpeed USB has the backing of many major desktop makers and allows power transport as well as data transport, an advantage over Wi-Fi and other wireless, said Jeff Ravencraft, president of the USB-Implementers Forum.

The USB trade groups are also backing a new power delivery specification, USB Power Delivery, that was first announced last July. The standard aims to reduce the variety of chargers used for smartphones and tablets. It has a variety of different profiles, which can supply up to 100 watts of power through the cable.
