Recommendations:

2 x IF and 1 x RF lightning arrestor should be used

Crimp-able F connectors must not be used for RG-11


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


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)


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)

antenna alignment


AN-50e Tx Parameters

Max power @ 64QAM is constrained by signal and IM distortion ATPC: Executed every 50 ms

Looks at the SINADR on the other side and adjusts Tx power @ 1dB steps


UK Operation

The AN50e is capable of operating in the band B (5470 - 5725MHz) and Band C (5725 – 5850MHz)

In Band C, 5795 – 5815MHz may not be used, Although OFCOM recently indicated that in 2005 – this restriction may be removed

OFCOM have set operational limits in these bands in documents IR2006 and IR2007

The current Maximum EIRP of a terminal operating in Band C is 2W

The current maximum EIRP of a terminal operating in Band B is 1W

DFS and TPC must be used, Without ATPC, systems may be used +3dB below current maximum EIRP

Campus Network Scenario

Between Subscriber (SS1) and Switch (SW1) Each VLAN segment is assigned a unique VID E.g. Dept 1 packets are tagged w/ VID=300 Each VID has a CIR (minimum bit rate)

For each VLAN segment A virtual group is defined as a multicast domain E.g. Group I for Dept 1 at Site 1 and Site 2 Each group has a multicast CIR

Within each virtual group VID can differ at each site E.g. Group II for Dept 2

packet VID=400 at Site 1 packet VID=700 at Site 2

Data between Dept 1 & 2 Through Router Layer 3 connectivity only

• Dept 1 packets tagged with VID= 300




• All Dept 1 connections set to Group I

• All Dept 2 connections set to Group II

V3.0 configuration notes

Max # of SS’s per sector is 20 Max # of groups per sector is 30 Max # of connections (VIDs) per link is 12 Max # of MAC addresses per group is 4000 Max # of IDs (link, group, connection) per sector is 1000

Each connection (VID) must belong to one group and one group only

Each connection (VID) must belong to one link and one link only Each group can have only one connection (VID) at a subscriber or

section controller

A pass-through group is used to pass “untagged packets” and “tagged, but undefined” packets

There can be only one pass-through group at a SC There can be only one pass-through connection at a SS
