Expert is also cognizant of Packet over SONET (PoS) technology and 10 Gigabit Ethernet connection to a SONET network at OC-192. He produced a comprehensive 300-page market study on these technologies, which is sold globally through the IGI Group.
He has expertise on wide area networks (WANs). He is cognizant of the International Standards Organization's (ISO) Open Systems Interconnection (OSI) protocol stack, which divides communications into seven independent protocol layers. He is familiar with asynchronous, isochronous, and synchronous networks, half- and full-duplex transmission, network protocols (such as SDLC, HDLC, TCP/IP, and SNMP), network interfaces, signaling, permanent virtual circuits (PVCs), switched virtual circuits (SVCs), and multiplexing technologies including frequency division multiplexing (FDM) and time division multiplexing (TDM), switching, X.25 packet switching, frame relay (a fast packet switching technique), Fractional T1, T1/E1, and T3/E3, ISDN Basic Rate and Primary Rate transmission and Asynchronous Transfer Mode (ATM) technology. He is familiar with modems, modem pooling, statistical and T1 multiplexers, CSU/DSUs, Channel Banks, Digital Access and Cross-connect Systems (DACS), X.25 Packet Assembler/Disassemblers (PADs), Frame Relay Assembler/Disassemblers (FRADs), and communication processors. He is also cognizant of digital encoding techniques, such as Pulse Code Modulation (PCM), Adaptive PCM (APCM), Differential PCM (DPCM), and Adaptive Differential PCM (ADPCM).
He has expertise in various types of broadband network concepts and technology for enterprises, service providers, and carriers, including T1/T3, E1/E3, ISDN (Basic Rate and Primary Rate), Digital Subscriber Line (DSL), Asynchronous Transfer Mode (ATM), Synchronous Optical Network (SONET), Synchronous Digital Hierarchy (SDH), Wavelength Division Multiplexing (WDM) Course WDM (CWDM) & Dense WDM (DWDM), and others, such as Gigabit Ethernet over SONET and Gigabit Ethernet and 10 Gigabit Ethernet over WDM. He has developed a seminar on ATM technology. Expert is also cognizant of Resilient Packet Ring (RPR) technology for metropolitan area networks (MANs).
He also specializes and has expertise in wireless communication and technology. He is cognizant of wireless concepts established by vendors in the wireless industry and wireless standards created by the IEEE 802.11 Task Group. He is cognizant of protocols, and security measures such as the IEEE 802.11i standard which the Wi-Fi Alliance dubbed Wi-Fi Protected Access (WPA). He maintains an awareness of ongoing development in the wireless industry, such as voice over wireless LAN (VoWLAN), as well as the development of wireless standards by IEEE 802.11 Task Groups, such as QoS for voice/data convergence on WLANs supported by IEEE 802.11e, fast roaming supported by IEEE 802.11i and developing IEEE 802.11r standards, VoIP, and emerging new concepts and technologies, such as IEEE 802.11n that promises minimum raw data rates of 100 Mbps, which has been dubbed MIMO for Multiple Input/Multiple Output, and IEEE 802.11s for mesh networks in this rapidly-growing industry. He is also in touch with the Wi-Fi Alliance and is cognizant of wireless IP phones produced by vendors such as Motorola and SpectraLink. Expert also remains in touch with the WIMAX Forum and the work it is doing to support the IEEE 802.16 Working Group on the Air Interface Standard for broadband wireless access applications. Expert is also familiar with the IEEE 802.15 Wireless Personal Area Networks (WPAN) standard and with Bluetooth and ZigBee WPAN technologies, which operate in the 2.4 GHz frequency spectrum.
