Microwave Transmission

High Performance Networks, 1994

The paper describes the design concepts that were applied to the development of a Gb/s Local/Metropolitan Area Network (LAN/MAN). The prototype network is based on the folded bus topology, operates at a data rate of 1.13 Gb/s and can span distances in excess of 50 km. With optical fibers being used for data transmission, nodes may be spaced up to 35 km apart without the need for repeaters. Data transmission in the fiber is based on a new 8B/10B code that yields excellent transmission properties. The access protocol is based on a slotted media approach that permits concurrent access to the media by multiple, geographically separated nodes. The protocol is reservation-based and thus guarantees a high degree of fairness in serving the nodes. Data payloads are transmitted in consecutive slots and data contiguity is preserved. The network is controlled by a headend that issues cycles composed of a varying number of slots; the number is determined by previously collected node requests for data transmission. The hardware of a network node is partitioned into boards providing the Physical Layer functions (block coding, parallel-serial and electro-optical conversion, including all inverse operations), Media Access Control functions and Data Buffering/Device Attachment functions. For every function and for all board interconnections the most suitable leadingedge, commercial technology was chosen. Since essentially all the control functions must be performed in real time very limited use of microprocessors could be made. All the control functions in a node are implemented with high-speed programmable logic devices, microsequencers and an Arithmetic Logic Unit. Only in the headend, the node that performs bus scheduling, is a RISC-type microcontroller used. A four-node network, transporting FDDI-backbone and high-resolution image traffic over a distance of 10 kin, was demonstrated in full operation at the TELECOM'91 exhibition in Geneva, Switzerland.

1. para sa HOP1 lang ito pero same lang yung computations para sa HOP 2,3,4 (kung ilan man yung hop na pinapagawa ni sir haha) 2. yung mga naka blue na lang yung papaltan nyo  3. yung path length ay distance between 2 towers in each hop 4. kapag may mga asteris (sorry sa spelling), ibig sabihin hindi sya kinompute, standard values sya for microwave design, (see notes and tables below). Pwedeng baguhin nyo o hindi depende sa design nyo.  5. WAG NYO NA MASYADO PANSININ YUNG COMPUTATION NA GINAWA SA EXAMPLE NA ITO, MAY MALI KASI SYANG SINUBSTITUTE, SORRY DI KO NA NAEDIT. SUNDAN NYO NA LANG YUNG FORMULA . 6. para sa full content ng paper at format, hiram na lang po kayo kay sir ng sample paper/design. Thank you.

TMR&D is developing a millimeter-wave point-to-point (PTP) Wireless Gigabit Ethernet Communication System. A 60 GHz Low Temperature Co-Fired Ceramics (LTCC) System-On-Package (SoP) Transceiver capable of gigabit data rate has been built and demonstrated with a size of 17.76 x 17.89 mm 2. A direct Amplitude-Shift Keying (ASK) modulation and demodulation scheme is adopted for the 60GHz-band transceiver. A BER of 1×10-12 for data rate of 1.25 gigabit-per-second (Gbps) on 2.2 GHz bandwidth at 1.4 km was demonstrated. This paper reports a new PTP link that has been installed at TMR&D site to demonstrate wireless gigabit operation and performance of its key components. The link will operate at the 57.65-63.35 GHz band incorporating TMR&D's designed millimeter-wave LTCC SoP RF Transceiver module. This LTCC SoP RF Transceiver is suitable for short-range wireless networking systems, security camera TV, video conferencing, streaming video like HDTV (high definition television) and wireless downloading systems for small power application.
