base station output power by 9 dB by means of built-in amplifier (for example to
use 300-500mW devices).

4. «Bad subscriber» problem
While working in Point-to-Multipoint topology wireless network could face a
problem when one of the subscriber devices has much poorer connection
characteristics to Base Station than the other ones. Such subscriber device is
using a considerable part of Base Station‘s resources. While Base Station is trying
characteristics to Base Station than the other ones. Such subscriber device is
using a considerable part of Base Station‘s resources. While Base Station is trying
to send him a packet on a low speed other subscribers are waiting for this
transaction to finish. Therefore, all the networks‘ performance will be reduced.
To lower the influence of such ―bad subscriber‖ on the overall wireless network‗s
performance it is recommended to decrease a priority of this subscriber (using
transaction to finish. Therefore, all the networks‘ performance will be reduced.
To lower the influence of such ―bad subscriber‖ on the overall wireless network‗s
performance it is recommended to decrease a priority of this subscriber (using
―qm‖ command). In this case all the packets to ―bad subscriber‖ will be sent
after other subscriber stations already get their portions of data. This will result
in wireless network performance optimization as subscriber devices‘ operation
after other subscriber stations already get their portions of data. This will result
in wireless network performance optimization as subscriber devices‘ operation
won‘t depend on the speed of ―bad subscriber‖.
5. WANFleX/MINT channel reservation
Channel reservation in InfiNet Wireless equipment can be done using several
ways. MINT-network itself determines which available channels to use for data
transmission. MINT algorithms are gathering data and perform calculations to
ways. MINT-network itself determines which available channels to use for data
transmission. MINT algorithms are gathering data and perform calculations to
find out the channel with the best parameters to use. Such calculations are done
fully automatically; moreover, MINT dynamically reconfigures network settings

and used channels according to environment conditions changes.
To perform channel reservation outside MINT-network, for example, in some
wired segment of the network connected to Ethernet interface of IW device,
STP/RSTP (Spanning Tree Protocol/Rapid Spanning Tree Protocol) are realized in
the system. These protocols are used in a switch mode and should be configured

using ―stp‖ option of the ―switch‖ command.
6. TDM transmission
InfiNet Wireless equipment allows E1/T1 flows transmission via the radio channel
in Point-to-Point topology. The System ensures transmission of 4 TDM channels
and 45 Mbps Ethernet data simultaneously. Moreover, IW devices with TDM
in Point-to-Point topology. The System ensures transmission of 4 TDM channels
and 45 Mbps Ethernet data simultaneously. Moreover, IW devices with TDM
support allow Multi-hop TDM transmission when E1/T1 data are sent via several
wireless Point-to-Point hops.
