Technologist Biography
As a technologist, Williams first worked at System Development Corp (SDC), where he served as a BSD UNIX system programmer. He contributed to a variety of early UNIX / Internet projects including Pearl with Larry Wall, and Warp, an early computer game to run on CRTs based on Star Trek. As CTO at Sonus Corp, he authored the program SuperScore, one of the first computer editing and printing programs for music. He and Cleo Huggins developed the Adobe Sonata Font. Williams also authored articles for the IEICE, Music Technology, Electronic Music Educator, and Klavier.
Williams was an early employee at Sun Microsystems in the kernel team and the OBP (Open Boot) team, and implemented the first IOMMU kernel software for DVMA (Direct Virtual Memory Access). He served as the Chief Technical Architect for Fujitsu Software, HAL computers, and represented Fujitsu in the SPARC 10 architecture committee [1] and the SPARC International certification organization. As a Senior IEEEE member, Williams served as the Vice Chair of the IEEE 802.21 working group, secretary for the IEEE 1275 Open Firmware working group, and member of the IEEE 1754 Open Microprocessor working group. He was awarded the title of Leading Scientist while working at Nokia. He represented Nokia at the Wi-Fi Alliance, IEEE (including 802.11i,s and 802.21) and 3GPP. Williams is co-author of IETF RFC 5412 "Lightweight Access Point Protocol", RFC 6520 "Transport Layer Security (TLS) and Datagram Transport Layer Security (DTLS) Heartbeat Extension" and Draft Mobile DTLS
Before the iPhone was released, Williams proposed "the computer phone" to the Nokia Technology Board. He led Nokia teams in negotiations with Google to create the first smartphone. Nokia withdrew from the negotiations. Google instead purchased several companies to create Android and the Pixel, while Apple went on to release the iPhone. Nokia did not create a smartphone, and went on to be purchased by Microsoft. Williams invented the "Interactive Broadcast Television [2] " Williams holds patents in a variety of areas including Wi-Fi, 3GPP, network security, clustering, authentication and secure search.
Wi-Fi is a family of wireless network protocols based on the IEEE 802.11 family of standards, which are commonly used for local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves. These are the most widely used computer networks, used globally in home and small office networks to link devices and to provide Internet access with wireless routers and wireless access points in public places such as coffee shops, hotels, libraries, and airports to provide visitors.
Sir George Albert Shearing was a British jazz pianist who for many years led a popular jazz group that recorded for Discovery Records, MGM Records and Capitol Records. Shearing was the composer of over 300 songs, including the jazz standards "Lullaby of Birdland" and "Conception", and had multiple albums on the Billboard charts during the 1950s, 1960s, 1980s and 1990s.
"Autumn Leaves" is a popular song based on a French song "Les Feuilles mortes" composed by Joseph Kosma in 1945. The original lyrics were written by Jacques Prévert in French, and the English lyrics were by Johnny Mercer. An instrumental version by pianist Roger Williams was a number one best-seller in the US Billboard charts of 1955.
Mulgrew Miller was an American jazz pianist, composer, and educator. As a child he played in churches and was influenced on piano by Ramsey Lewis and then Oscar Peterson. Aspects of their styles remained in his playing, but he added the greater harmonic freedom of McCoy Tyner and others in developing as a hard bop player and then in creating his own style, which influenced others from the 1980s on.
Meriwether Lewis Spratlan Jr. was an American music academic and composer of contemporary classical music.
Mobile VoIP or simply mVoIP is an extension of mobility to a voice over IP network. Two types of communication are generally supported: cordless telephones using DECT or PCS protocols for short range or campus communications where all base stations are linked into the same LAN, and wider area communications using 3G or 4G protocols.
The Nokia N95 is a mobile phone produced by Nokia as part of their Nseries line of portable devices. Announced in September 2006, it was released to the market in March 2007. The N95 ran S60 3rd Edition, on Symbian OS v9.2. It has a two-way sliding mechanism, which can be used to access either media playback buttons or a numeric keypad. It was first released in silver and later on in black, with limited edition quantities in gold and purple. The launch price of the N95 was around €550.
In radio, multiple-input and multiple-output (MIMO) is a method for multiplying the capacity of a radio link using multiple transmission and receiving antennas to exploit multipath propagation. MIMO has become an essential element of wireless communication standards including IEEE 802.11n, IEEE 802.11ac, HSPA+ (3G), WiMAX, and Long Term Evolution (LTE). More recently, MIMO has been applied to power-line communication for three-wire installations as part of the ITU G.hn standard and of the HomePlug AV2 specification.
In telecommunications, long-term evolution (LTE) is a standard for wireless broadband communication for mobile devices and data terminals, based on the GSM/EDGE and UMTS/HSPA standards. It improves on those standards' capacity and speed by using a different radio interface and core network improvements. LTE is the upgrade path for carriers with both GSM/UMTS networks and CDMA2000 networks. Because LTE frequencies and bands differ from country to country, only multi-band phones can use LTE in all countries where it is supported.

John Serry Jr. is an American jazz pianist and composer, as well as a composer of contemporary classical music works that feature percussion, on which he also doubles. He is a son of the accordionist and composer John Serry. His debut solo album was 'Exhibition', for which he received a Grammy Nomination for his composition, 'Sabotage'.
The Nokia N8 is a touchscreen-based smartphone developed by Nokia. Announced on 27 April 2010, the Nokia N8 was the first device to run on the Symbian^3 mobile operating system and it was the company's flagship device for the year. It was released on 30 September 2010 at the Nokia Online Store before being released in markets around the world on 1 October 2010. There were two version made, the N8 and the N8-00. The N8 was made for Vodafone and locked to its networks, and the N8-00 was made by Microsoft and open network.
IEEE 802.11ac-2013 or 802.11ac is a wireless networking standard in the IEEE 802.11 set of protocols, providing high-throughput wireless local area networks (WLANs) on the 5 GHz band. The standard has been retroactively labelled as Wi-Fi 5 by Wi-Fi Alliance.
Dynamic Adaptive Streaming over HTTP (DASH), also known as MPEG-DASH, is an adaptive bitrate streaming technique that enables high quality streaming of media content over the Internet delivered from conventional HTTP web servers. Similar to Apple's HTTP Live Streaming (HLS) solution, MPEG-DASH works by breaking the content into a sequence of small segments, which are served over HTTP. An early HTTP web server based streaming system called SProxy was developed and deployed in the Hewlett Packard Laboratories in 2006. It showed how to use HTTP range requests to break the content into small segments. SProxy shows the effectiveness of segment based streaming, gaining best Internet penetration due to the wide deployment of firewalls, and reducing the unnecessary traffic transmission if a user chooses to terminate the streaming session earlier before reaching the end. Each segment contains a short interval of playback time of content that is potentially many hours in duration, such as a movie or the live broadcast of a sport event. The content is made available at a variety of different bit rates, i.e., alternative segments encoded at different bit rates covering aligned short intervals of playback time. While the content is being played back by an MPEG-DASH client, the client uses a bit rate adaptation (ABR) algorithm to automatically select the segment with the highest bit rate possible that can be downloaded in time for playback without causing stalls or re-buffering events in the playback. The current MPEG-DASH reference client dash.js offers both buffer-based (BOLA) and hybrid (DYNAMIC) bit rate adaptation algorithms. Thus, an MPEG-DASH client can seamlessly adapt to changing network conditions and provide high quality playback with few stalls or re-buffering events.
Bernhard H. Walke is a pioneer of mobile Internet access and professor emeritus at RWTH Aachen University in Germany. He is a driver of wireless and mobile 2G to 5G cellular radio networks technologies. In 1985, he proposed a local cellular radio network comprising technologies in use today in 2G, 4G and discussed for 5G systems. For example, self-organization of a radio mesh network, integration of circuit- and packet switching, de-centralized radio resource control, TDMA/spread spectrum data transmission, antenna beam steering, spatial beam multiplexing, interference coordination, S-Aloha based multiple access and demand assigned traffic channels, mobile broadband transmission using mm-waves, and multi-hop communication.
Per-user unitary rate control (PU2RC) is a multi-user MIMO (multiple-input and multiple-output) scheme. PU2RC uses both transmission pre-coding and multi-user scheduling. By doing that, the network capacity is further enhanced than the capacity of the single-user MIMO scheme.
