Wintegra Expands WiMAX Offering to Include Complete Base Station Development Platform and MAC and Transport Software.Reference Boards and Upper/Lower MAC Add to Growing Suite of WiMAX SolutionsAUSTIN, Texas -- Wintegra[R] Inc., a fabless semiconductor company A fabless semiconductor company specializes in the design and sale of hardware devices implemented on semiconductor chips. It achieves an advantage by outsourcing the fabrication of the devices to a specialized semiconductor manufacturer called a semiconductor foundry or "fab. targeting the access infrastructure market, announced today two significant milestones in its expanding WiMAX product offering. These include the introduction of a complete fixed and mobile 802.16e upper and lower MAC with integrated network interface and transport functions, and the announcement that the 802.16e base station development platform, WinHDP, is now shipping to customers. Both the MAC and the platform were successfully used by multiple 802.16e base station vendors to interoperate with subscriber stations and CPE (Customer Premises Equipment) Communications equipment that resides on the customer's premises. CPE - Customer Premises Equipment solutions in the WiMAX Forum "Plugfest" event held in Frederick, Maryland in September. The Wintegra WinHDP development platform has been shipped to numerous WiMAX customers worldwide - including customers in North America, Europe, Israel, Japan and Taiwan. The base station development platform provides direct connectivity between the Wintegra MAC and picoChip PHY See physical layer and physical. , and state-of-the-art RF and antenna subsystems, which together create a demonstrable WiMAX base station that has successfully interoperated with multiple CPE solutions. Fully tested software and vendor independent APIs are available for rapid system integration of these components, as well as optional licensing of tools and source code for OEMs to customize and differentiate their systems. This platform is modular and scalable, and is capable of supporting any size base station from pico-cell, to multi-sector, multi-protocol macro base station designs. WinHDP gives OEMs the capability to realize the benefits of reduced time to market as well as field upgradeability. Key Features of the WinHDP base station platform include: * Lower and upper MAC from Wintegra * WiMAX PHY from picoChip * Interface for AAS/MIMO antenna * Flexible software-defined baseband silicon from picoChip The Wintegra 802.16e MAC is a full featured and fully programmable lower and upper MAC implementation that supports both mobile and fixed WiMAX operation. Key features include: FDD (1) Abbreviation for floppy disk drive. See floppy disk. (2) (Frequency Division Duplexing) A transmission method that separates the transmitting and receiving channels with a guard band (some amount of spectrum that acts as a buffer or insulator). and 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 mode support; Point-to-Multipoint topology; multi-zone support; support for 512 subscribers; numerous queues per connection; and enhanced statistics support. The MAC is highly modular and flexible, allowing rapid adaptation to standards changes as well as integration of proprietary customer modules and features. The code is fully integrated with Wintegra production quality wireless data path software packages. All of this MAC software can run on the WinHDP and is shipping to customers worldwide. Key MAC Features: * Enhanced Packed Convergence Sublayer Support * Up to 64K CIDs * Payload Header Compression * Common Part Sublayer Support * Fully integrated security and Privacy Sublayer support * Multi-sector support on a single device (three sectors) * Field upgradeable for 802.16d or 802.16j * Handover scanning and power control * Modular PHY interface Key Transport Features: * WiMAX Forum Network Interface, including R6 and R8 specifications * Sophisticated classifier and QoS, with priority remapping, policing and congestion control * GRE (Generic Routing Encapsulation) A tunneling protocol developed by Cisco that allows network layer packets to contain packets from a different protocol. It is widely used to tunnel protocols inside IP packets for virtual private networks (VPNs). and IP-in-IP tunneling support * Software programmable backhaul * Ethernet, Gigabit Ethernet, TDM (Time Division Multiplexing) A technology that transmits multiple signals simultaneously over a single transmission path. Each lower-speed signal is time sliced into one high-speed transmission. , POS (1) See point of sale and packet over SONET. (2) "Parent over shoulder." See digispeak. POS - point of sale and ATM interfaces * Payload Header Suppression (PHS (Personal Handyphone System) A TDMA-based cellular phone system introduced in Japan in mid-1995. Operating in the 1880-1930 MHz band, PHS uses microcells that cover an area only 100 to 500 meters in diameter, resulting in lower equipment costs but requiring more base ) * Interface for ASN (1) (Autonomous System Number) A unique identifier of an autonomous system on the Internet. Of the 65 thousand ASNs available, more than 30 thousand have been assigned to ISPs and NSPs. ISPs usually have only one ASN, but NSPs may have more than one. gateway, including handover support About Wintegra, Inc.
