Patent number: 6407992Abstract: A method of multiplexing multiple terminals in a distributed network includes transporting user traffic and telephony signaling information. Transporting user traffic includes converting the user traffic into ATM cells, passing the ATM cells over a wireless link to a TDM port in an ATM multiplexer wherein the ATM multiplexer includes an ATM circuit emulation service, and converting the ATM cells into user traffic. Transporting telephony signaling information includes extracting the telephony signaling information from a user interface, passing the telephony signaling information to a base station using an ATM virtual circuit, processing and aggregating a number of telephony signaling information into a single channel, and transmitting the single channel to the ATM multiplexer.Type: GrantFiled: August 11, 2000Date of Patent: June 18, 2002Assignee: Netro CorporationInventors: Eliezer Pasternak, Itai Aaronson, Gideon Ben-Efraim

Patent number: 5936949Abstract: The present invention provides an efficient point-to-multipoint microwave ATM network including a base station (BS) broadcasting a continuous transmission with a sector antenna. The system uses time division multiplex (TDM) for downstream transmission and time division multiple access (TDMA) for upstream transmission. The downstream transmission consists of ATM cells encapsulated in MAC protocol data units (PDUs) for forward error correction (FEC) and synchronization. Small Subscriber Terminals (STs), including Subscriber Radio Units (SRUs), receive the broadcast and pass it to a Subscriber Access System (SAS) that drops the ATM cells addressed only to them. To allow strong FEC protection and to maintain the same symbol rate as the downstream transmission without sacrificing bandwidth, a modified trellis code modulation technique, which incorporates Reed Solomon coding, is used during upstream transmission.Type: GrantFiled: September 5, 1996Date of Patent: August 10, 1999Assignee: Netro CorporationInventors: Eliezer Pasternak, Gideon Ben-Efraim, Stuart M.

Patent number: 5648969Abstract: A digital radio link suitable for transmitting digital voice or data signals includes an input circuit for ATM or equivalent cells, a processing circuit to encapsulate the input cells received by the input circuit with at least error check bits so that detected error can identify a specific cell or group of cells, a digital transmission circuit for transmitting the encapsulated cells via a wireless link, a reception circuit for receiving encapsulated cells from an opposite side of the digital radio link, a cell decapsulation and error detection circuit connected to said reception circuit and a cell output circuit for connecting said decapsulation circuit to a digital access unit. The system includes structure for allocating more than one type of service, such as low delay service for voice transmission and extensive forward error correction service for data transmission.Type: GrantFiled: February 13, 1995Date of Patent: July 15, 1997Assignee: Netro CorporationInventors: Eliezer Pasternak, Gideon BenEfraim
