An Ant-Sized IoT Radio

  • PDF

UC Berkeley and Stanford University engineers develop a possible solution for the wireless demands of the Internet of Things-- a cheap tiny (3.7mm x 1.2mm) dual-band radio powered by the signals it receives.

tiny radioSimilar tiny radios already exist, but unlike similar solutions (which operate on low frequencies), the Berkeley/Stanford radio receives data on the 24GHz band and transmits on 60GHz. This reduces the power requirements by so much the radio charges itself with energy from received signals.

Higher frequencies also allow very fast data transmission rates, even if in the data transmitted is of low volume.

“One of the benefits of going to high frequencies is that the wavelengths get smaller and you can put the antennas on the chip itself,” UC Berkeley Wireless Research Center director Ali Niknejad tells Wired.

Broadcom Intros "Most Powerful" 5G Wifi Chip

  • PDF

Broadcom claims to double the wifi performance in upcoming smartphones and tablets with the BCM4358, a 5G 802.11ac wifi 2x2 Multiple Input Multiple Output (MIMO) combo chip.

Broadcom mobileMIMO technology uses multiple antennas for both transmitter and receiver. It is already found in the iPad Air and iPad mini with Retina Display.

"The combination of 5G WiFi and 2x2 MIMO unlocks the full potential of today's smartphones and tablets. These technologies are becoming de facto requirements for connectivity in high-end mobile devices," the company says. "With the BCM4358 we are addressing critical multi-radio interference challenges while setting a new bar for performance that reflects Broadcom's continued commitment to be first to deliver the most powerful solutions in the market."

The Smallest Modem for the IoT

  • PDF

Intel reveals what it claims is the smallest standalone 3G modem in the world-- the XMM 6255, a chip around 300m2 in size designed for networked sensors, wearable devices and other Internet of Things (IoT) applications.

Intel modemIt features a SMART I UE2p transceiver, an Intel design combining transmitter and receiver functionality with an integrated power amplifier and power management on a single chip.

Intel says the design not only allows for a smaller modem, but also protects the radio from overheating, voltage peaks and damage from tough conditions. It also simplifies the design and minimises production costs.

Qualcomm Bets on WiGig With Wilocity Buy

  • PDF

Qualcomm moves forward in WiGig 60GHz wireless technology (aka 802.11ad wifi) adoption with the acquisition of pioneer Wilocity and the announcement of a mobile SoC reference design featuring the technology.

Qualcomm Wilocity"WiGig will play an important role in Qualcomm's strategy to address consumers' increasingly sophisticated smartphone, tablet and computing requirements," the company says. It does not reveal how much it paid for Wilocity, but its pricetag was reportedly set at around $300 million.

Wilocity is one of the founding members of the 802.11ad working group, and already sells WiGig solutions to Dell and Cisco.

Wi-Fi Multicast

Taiwan's Industrial Technology Research Institute (ITRI) reveals a new streaming technology that solves Internet congestion, especially in dense areas such as stadiums or concerts halls-- and the technology can also be used on high-speed trains.

Similar to broadcasting theory, the Wi-Fi Multicast technology allows 10X more users to use the same amount of bandwidth as provided by typical streaming services.

Wu Cheng-wen, general director of ITRI's Information and Communications Research Laboratories, says their software can change the coding of video data eliminating the need to buy and install new equipment.

ITRI is now talking to potential partners, including cable companies, to transfer the technology for business use. The technology could solve the growing demand for online video sharing and viewing.
