Hitachi Kokusai Electric Showcases 24GHz Unlicensed Band 150Mbps Point-to-Point System at CTIA WIRELESS 2006; System Enables Wireless Ethernet Applications.LAS VEGAS -- Hitachi Kokusai Electric Inc., a global supplier of wireless infrastructure solutions, and Hitachi Telecom (USA), Inc. today announced that they will showcase Hitachi Kokusai's 24GHz unlicensed band Broadband Wireless Point to Point (P-P P-P Peak to Peak ) solution at CTIA (1) See CompTIA. (2) (Cellular Telecommunications & Internet Association, Washington, DC, www.ctia.org, www.wow-com.com) A membership organization founded in 1984 that is involved with regulatory and public affairs issues in the wireless industry. WIRELESS 2006, the premier event for the global mobile and wireless industry. Nearly 1,000 manufacturers, suppliers, and telecom operators will gather at the Las Vegas Convention Center The Las Vegas Convention Center is owned and operated by the Las Vegas Convention and Visitors Authority and is located in Clark County, Nevada. It is one of the largest Convention centers in the world. At the end of 2004, the center had 3. to exhibit the latest in wireless infrastructure, mobile and wireless devices, wireless services, semiconductors, test and measurement equipment, and consumer and business software applications. Hitachi Group will exhibit in booth No. 5911. Hitachi Kokusai's 24GHz unlicensed band Broadband Wireless Point to Point (P-P) system operates within the unlicensed radio frequency range of 24.050 - 24.250GHz, ensuring less interference and higher performance for customers' traffic compared to other congested con·gest·ed adj. Affected with or characterized by congestion. congested ENT adjective Referring to a boggy blood-filled tissue. See Nasal congestion. unlicensed bands. Other advantages of the Hitachi Kokusai unit include light weight (6.6 lbs (3 kg)), small plane surface antenna (11.4" x 11.4" (29 cm x 29 cm)), easy installation using the "Ethernet cable connect only" features supported by Power over Ethernet Power over Ethernet or PoE technology describes a system to transmit electrical power, along with data, to remote devices over standard twisted-pair cable in an Ethernet network. (PoE), and 100BASE-TX Ethernet full duplex connectivity. The system is extremely easy to deploy and manage, with a SNMP (Simple Network Management Protocol) A widely used network monitoring and control protocol. Data are passed from SNMP agents, which are hardware and/or software processes reporting activity in each network device (hub, router, bridge, etc. network management option. The Hitachi Kokusai 24GHz unlicensed band Broadband Wireless Point to Point (P-P) system enables in-service wireless Ethernet with innovative adaptive modulation from QPSK (Quadrature Phase Shift Keying) A phase modulation technique that transmits two bits in four modulation states. See PSK and phase modulation. , 16QAM (1) (Quality Assessment Measurement) A system used to measure and analyze voice transmission. (2) (Quadrature Amplitude Modulation) A modulation technique that employs both phase modulation (PM) and amplitude modulation (AM). to 64QAM, up to 150 Mbps air data rates TDD (Time Division Duplexing) A transmission method that uses only one channel for transmitting and receiving, separating them by different time slots. No guard band is used. Contrast with FDD. See also TDD/TTY. TDD - Telecommunications Device for the Deaf Point to Point. The system provides 56Mbps throughput for both uplink and downlink operation. The 24GHz unlicensed band Broadband Wireless Point to Point unit has already been FCC approved, and is installed in a number of customer networks in Japan at 25GHz, which is allocated as an unlicensed frequency band in Japan. "The demand for wireless Ethernet applications is strongly expanding, and this unlicensed band Broadband Wireless Point to Point system is one of our answers to the market," said Giho Makino, Executive Officer and General Manager, Wireless Communication Systems Division, Hitachi Kokusai Electric Inc. "Our 24GHz unlicensed band Broadband Wireless Point to Point system addresses such requirements and provides high bandwidth connectivity using the available unlicensed band."
