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.
The Wi-Fi Alliance has expanded its Passpoint program, which provides seamless connection and WPA2 security, to include a streamlined method to establish new user accounts and connect Wi-Fi-only devices.
The WiFi Alliance is a non-profit trade organization formed to provide interoperability between device and promote the benefits of WiFi. The new features in Passpoint are particularly valuable to mobile and fixed operators, and open opportunities for other sectors, says the organization.
“Wi-Fi-first” business models have provided a disruptive counterpoint to traditional operator services, and retailers are deploying Wi-Fi as a way to improve customer engagement, says The Alliance. Wi-Fi roaming agreements among service providers are emerging as an important complement to traditional cellular roaming.
“Enthusiasm for Passpoint from both mobile and fixed operators continues to mount, and the strategic value of Passpoint extends into new segments as well,” said Edgar Figueroa, CEO of Wi-Fi Alliance. “What makes the new features exciting is that they empower businesses to realize the powerful commercial impact that Wi-Fi can offer by giving them the ability to engage with customers on a new platform in a secure and streamlined fashion.”
Passpoint was launched in 2012 and is based on Wi-Fi Alliance’s Hotspot 2.0 Technical Specification. Fixed and mobile operators, including Boingo, Orange, SK Telecom, and Time Warner Cable. More than 20 operators are now participating in Wi-Fi roaming trials based on Passpoint.
The Passpoint program expansion builds on its foundational authentication and security mechanisms, adding features that make Passpoint more versatile and scalable:
Online sign-up and immediate account provisioning: Passpoint now enables a streamlined process to establish a new user account at the point of access.
Secure registration: The process of establishing a new account or connecting a second device takes place securely.
Operator policy: Passpoint now includes the capability for service providers to distribute their specific subscriber policies, such as which networks to join and in what order of preference.
The Passpoint certification program test suite includes support from Aruba Networks, Broadcom, Cisco, Ericsson, Intel, Marvell, MediaTek, Qualcomm Atheros, and Ruckus Wireless.
