CSR, which is short for Cambridge Silicon Radio, is a pioneer in Bluetooth and its silicon is in portable audio speakers and Apple-owned Beats headphones. CSR rejected a takeover bid from Microchip Technology in August. CSR’s deal with Qualcomm is expected to close by the end of the summer of 2015.
Classic Bluetooth and Bluetooth Low Energy chips are quickly getting commoditized, but CSR is a pioneer of the short-range wireless technology and is now pushing CSRmesh, a ZigBee-like mesh technology built on Bluetooth. CSR sees CSRmesh as a linchpin for its foray into the IoT market, reports EE Times.
In July Qualcomm bought WiGig chipmaker Wilocity, a move designed to enable Qualcomm to easily integrate the 60 GHz Wi-Fi technology into its mobile platforms to enable wireless streaming of 4K video for mobile and settop devices. Qualcomm also developed AllJoyn, an open-source platform that allows devices to share information with other nearby devices.
White space technology in the UK was among the first of its kind in Europe. Their pilot projects utilize unused terrestrial TV broadcasting channels (from 470 MHz to 790 MHz).
For this reason the Weightless SIG is developing a variant called Weightless-N. The two variants of the Standard, Weightless-W (for White Spaces) and Weightless-N (for the unlicensed ISM band) will coexist offering benefits to developers and users according to their specific use cases. Weightless-N will typically be deployed in unlicensed spectrum in the region 800-900MHz such as the 868MHz band in Europe and the 900MHz ISM band in the US. It is also designed to work in licensed spectrum around these frequencies.
The Weightless connectivity platform was developed by Neul (the Gaelic world for ‘cloud’). It was first targeted at the TV white spaces (TVWS) spectrum, but extending the spec to 900MHz and other bands (including licensed) requires some modificiations. The unlicensed bands are narrower than those found in TVWS, and that required some changes to the air interface which are found in Weightless-N. Neul itself has released the first commercial chipset to support the would-be standard, called Iceni.
The Narrowband IoT is designed to work at sub-gigahertz frequencies as part of future 3GPP cellular standards for connecting low data rate devices that have exceptionally long battery life. There is great spectrum efficiency using just 200kHz. It will work at the 450, 850 and 900MHz frequencies used by GSM and at the lower frequencies that some LTE uses.
The CEO of the Weightless special interest group, Professor William Webb, offered up some comment on the launch of Weightless-N, saying “Enabling the vision of 50 billion connected devices requires chipset costs below $2, battery life of 10 years or more and a range of 5km or more to ensure ubiquitous coverage from a low cost network.
The 802.11af standard, based on Wi-Fi like protocols, is designed for ranges up to 5 km, while the 802.22 standard is based on WiMax chipsets and incorporates polling, for wireless regional area networks with ranges up to 100 km.
PX4 is an independent, open-source, open-hardware project aiming at providing a high-end autopilot. The PX4 from 3D Robotics, for example, features advanced processor and sensor technology for controlling any autonomous vehicle.
“By becoming a Linux Foundation Collaborative Project, the Dronecode community will receive the support required of a massive project right at its moment of breakthrough. The result will be even greater innovation and a common platform for drone and robotics open source projects.”
According to Iliad, “Following this offer rejection, Iliad put in place a consortium with two leading private equity funds and Tier-1 international banks allowing it to improve significantly the terms of its offer by enhancing the cash amount and increasing the share of T-Mobile US’ capital to be acquired from 56.6% to 67%”. This new offer was valued at about USD 36 per share.
More than 8 million consumers flocked to Free Mobile as Orange and France’s two other wireless operators, Vivendi’s SFR and Bouygues suffered steep declines in sales. In April, Vivendi vacated the market altogether by selling SFR to Luxembourg-based Altice in a deal valued at 17 billion euros, reports Bloomberg.
Free offers 20 GB/mo 4G service along with unlimited voice and messaging for $US27/month. The Freebox Revolution router, which delivers a triple play of broadband, TV and landline telephone calls to Iliad’s 6 million subscribers, is a big reason Iliad’s stock returned 151 percent in the three years ended on June 24.
Orange and Bouygues Telecom, France’s third-largest mobile provider, had discussed partnership to buy SFR, but now Altice will merge SFR, France’s second-largest mobile provider, with its French cable unit Numericable.
KT’s Gigatopia strategy involves building a high-speed, integrated wired/wireless next-gen network that is ready for all manner of future media and data transport and geared up for the Internet of Things. The Cloud-based wireless network approach was largely developed by AlcaLu subsidiary Nuage Networks.
Evolved Packet Core is an evolution of the packet-switched architecture used in GPRS/UMTS. The use of individual circuits to carry voice and short messages are now being replaced by IP-based solutions. The radio access network (RAN) provides the radio access technology. Much of that cellular hardware is now being “virtualized” in the data center.
Cloud RAN virtualizes the hardware. Hardware that was once located on the mast or at the base of a cellular tower is now being replaced by software running in a data center, creating a virtualized radio network. A fiber link connects the remote RF head to the data center. Alca-Lu’s CloudBand platform is one of the leaders bringing cloud computing and IT technologies to wireless networks.
The Alcatel-Lucent opened a Customer Network Center in Japan this month. It was created to make the trend towards cloud-based networking, tangible for customers. It will allow for demos and interoperability testing of virtualized solutions over the CloudBand NFV platform to support Alcatel-Lucent’s Japan NFV/Network Transformation initiative which is already under way in Japan.
Samsung Electronics today announced a 60GHz (802.11ad) Wi-Fi technology that enables data transmission speeds of up to 4.6Gbps, a five-fold increase from 866Mbps, using the 5 GHz band. The 60 GHz Wi-Fi technology will enable a 1 gigabyte movie to be transferred between devices in less than three seconds while allowing uncompressed high-definition videos to be streamed from mobile devices. Samsung likely to include WiGig as a differentiator in its Galaxy and
Note smartphones by the end of 2015, say industry observers.
The Wireless Gigabit Alliance (WiGig) was a trade association that developed and promoted the adoption of multi-gigabit speed wireless standards over the unlicensed 60 GHz frequency band. The alliance was subsumed by the Wi-Fi Alliance in March 2013.
Samsung notes there are challenges in commercializing 60 GHz Wi-Fi because millimeter waves that travel by line-of-sight and have weak propagation characteristics that will be easily blocked by walls.
IEEE 802.11n: Increased the maximum raw data rate from 54 Mbit/s to 600 Mbit/s by using as many as four spatial streams with a double width channel (40 MHz). MIMO architecture and wider channels improved speeds on 5 GHz and 2.4 GHz channels.
IEEE 802.11ac: Provides high throughput in the 5 GHz band. It uses 80 MHz and 160 MHz channel bandwidths (vs. 40 MHz maximum in 802.11n) and supports up to 8 spatial streams (vs. 4 in 802.11n)
The unlicensed 60 GHz band varies slightly around the world. The standard divides the unlicensed 60 GHz band into four 2.16 GHz wide channels. Data rates of up to 7 Gbits/s are possible using OFDM with different modulation schemes. A single-channel version for low-power operation is available and can deliver a speed up to 4.6 Gbits/s.
ABI Research estimates over 1.5 billion chipsets with 802.11ad will ship in 2018. Smartphones will account for nearly half of all 802.11ad-enabled products in 2018, though with less than half the volume in smartphones compared to 802.11ac, says the research firm.
