4 AN-50e Core Technologies
Orthogonal Frequency Division Multiplexing (OFDM) Dynamic Time Division Duplexing (DTDD) Proprietary MAC Allows for PTP and PMP configuration Proprietary RF System T-58e Radio: GHz T-54 Radio: GHz Channel Size: 20 MHz Channel centre frequency 5 MHz steps Redline Communications

5 AN-50e Applications Examples
Internet access Backhaul of lower speed fixed wireless access point traffic WAN/LAN Connectivity Video/Security Connections Intra/Inter PBX Extensions VoiP Applications Enterprise Carrier ISP/WISPs BFW AN-50 MUSH, Govt. Security, Banks…. AN-50 is a transparent Ethernet bridge. The data must be in the form of Ethernet packets for the AN-50 which takes the packets and prepares them for transmission over the air to the remote AN-50. The remote AN-50 transforms the data back to the Ethernet format and hands over to the network through its Ethernet switch. So, the two network segments that the AN-50 wireless link connects are essentially unaware of the presence of the AN-50 system in between them. To ensure reliable high speed connectivity between, the AN-50 uses OFDM at the physical layer along with a number of other established coding methods and technologies. Redline Communications

6 Point to Multi-Point (PMP)
AN-50e PMP Application Point to Multi-Point (PMP) Software upgrade from PTP Base Station (B.S.) uses Sector Antenna 90 degrees 60 degrees 120 degrees Omnidirectional Data/Voice Applications Subscriber Stations (S.S.) In PTP application, the AN-50 link consists of two AN-50 systems talking to each other using Time Division Duplexing (TDD) which is essentially a ping-pong approach. In this application, one of the AN-50 terminals (the one local to the user) is designated as the Master and the one which is remote to the user as Slave. The AN-50 can be deployed as PMP system too, using the special software. In a PMP application in which case the Master is called the Base station (BS) and the remote terminals are called subscriber stations (SS). Redline Communications

AN-50e MAC Attributes PTP and PMP Configuration Patented ARQ Single retransmission to minimize latency Retransmission is done at 2 levels below primary speed Data Encryption MAC add based proprietary 64 bit encryption Always enable encryption for better system performance Packet concatenation Multiple Ethernet frames in a wireless frame Wireless frame could be up to 4095 bytes In PTP application, the AN-50 is a dynamic TDD system. For the PMP application, AN-50 uses TDMA for subscriber access to the base station. The AN-50 MAC functionalities are as given in the slide. Redline Communications

12 AN-50e Network Attributes
DHCP pass-through AN-50 can not obtain IP add from a DHCP server 802.3x – flow control MUST be on for TDM support Partial 802.1p/1Q support – prioritizing packets as high (4 – 7) or low (0 -3) Redline Communications

13 AN-50e Physical Layer (PHY)
Multi-carrier transmission technique Conventional telecom is single carrier AN-50/AN-30 use 64 carrier OFDM 48 is used to carry data Combats multi-path distortion effectively Minimizes frequency selective fading (FSF) Eliminates Inter-symbol Interference (ISI) Redline Communications

14 AN-50 Data Rates And Throughput
Dynamically adapts burst rate to link conditions Modulation Scheme Code Rate (FEC) Over the air rate (Mbps) UBR (Mbps) Throughput (Mbps) SINADR (dB) BPSK 1/2 12 6 5.7 8 3/4 9 8.6 10 QPSK 24 11.4 11 18 17 16QAM 48 22.4 15 36 33 64QAM 2/3 72 43.2 23 54 48.9 25 The table shows the bit rates supported by the AN-50. Each bit rate requires certain minimum SINADR (see the slide on Rx performance). In AN-50, a particular bit rate is realized using a combination of modulation and coding pre-coded in the AN-50 system. Links with poor SINADR conditions are supported using the lowest available code rate to ensure data integrity while maintaining throughput. The fact that throughput is less than the uncoded burst rate is due the overhead being added by the MAC. AN-50 allows only one retransmission of an erroneous packet and this does not contribute significantly to the fall of throughput. The coding rates used in AN-50 is the one defined by the BFWA standards. Observe that at higher bit rates, throughput to uncoded bit rate is higher for lower modulation schemes. This could be attributed to the longer processing time within the MAC and OFDM engines at higher data rates. The OFDM pilot tones are always BPSK modulated and transmitted at 6 Mbps uncoded rate. This is done to ensure the control information is received without any error. Note that while the AN-50 system is using 64QAM to transmit data, it is also simultaneously using (during the same symbol duration of 4 us) BPSK to transmit control information such the PHY overhead data and the pilots.
