Career

Perspective
In the 1980s, Rakib served as a communications engineer in the Israeli Navy.[8] Rakib also served as Chief Engineer at the communications products company PhaseCom from 1981 to 1993. As part of PhaseCom, he developed data and telephony applications.[6]
Shlomo Rakib founded Terayon in 1993 with his brother Zaki Rakib (IPO in 1998).[5][9][10][11] The company initially sold modems before developing other types of broadband technology.[12] Rakib served as the company's president and CTOs.[13][14]
Rakib invented Terayon's S-CDMA technology, which is a component of the DOCSIS 2.0 cable data specification used in cable modems.[9][15][16][8] As part of Terayon, he also developed data transmission methods utilizing Asynchronous Transfer Mode (ATM) and S-CDMA.[17] Rakib resigned as Terayon's president in 2004.[18] The firm was acquired in 2007 by Motorola.[19][20] This S-CDMA technology that Rakib developed allowed for more efficient utilization of the available bandwidth by allowing multiple signals to occupy the same frequency spectrum simultaneously.[21] It also improved security and reduced interference.[22]
In 2004, Rakib co-founded Novafora, a company that developed microprocessors for advanced video applications.[23][5] The firm acquired semiconductor and microprocessor company Transmeta in 2009 before it eventually closed in the same year.[24][25][26][20]
Rakib and Ronny Hadani co-founded Cohere Technologies in 2009.[27][28] They met at one of Hadani's lectures about Orthogonal Time Frequency and Space (OTFS) at the University of Texas at Austin.[29][30][31] and founded the company after Rakib devised the idea to apply OTFS to wireless technology and signal processing.[29][30] The firm focuses on wireless improvements using OTFS and the Delay-Doppler model to improve FDD/TDD spectrum performance.[30][32][33]
In 2012, Rakib founded Gainspeed, a company specializing in DAA (Distributed Access Architecture). The company was initially known as Cohere Networks before being renamed Gainspeed in 2013.[34] The firm was acquired by Nokia in 2016.
In 2021, Rakib became a member of CableLabs' Convergence Council, an advisory board focused on building convergence in the cable industry.[35][36]
