The maximum message size quota for incoming messages (65536) has been exceeded

I am using WCF for file uploading and downloading. uploading is successful but when i downloading a large file i found this error

Error : The maximum message size quota for incoming messages (65536) has been exceeded. To increase the quota, use the MaxReceivedMessageSize property on the appropriate binding element.

My Service.config file has the following code.

<system.web>
    <compilation debug="true" />
    <httpRuntime executionTimeout="4800" maxRequestLength="2147483647" />


  </system.web>
  <system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" maxBufferPoolSize="524288">
          <readerQuotas maxDepth="32" maxStringContentLength="2147483647" 
            maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647"  />
        </binding>
      </basicHttpBinding>
      <!--<webHttpBinding>
        <binding maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" />
      </webHttpBinding>-->
    </bindings>
    <services>
      <service name="WITSService.WITSService">
        <clear />
        <endpoint binding="basicHttpBinding" contract="WITSService.WITSService" />
      </service>
    </services>

    <behaviors>
      <serviceBehaviors>
        <behavior>
          <serviceMetadata httpGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="false"/>
          <dataContractSerializer maxItemsInObjectGraph="2147483646"/>
        </behavior>
      </serviceBehaviors>
      <endpointBehaviors>
        <behavior name="myEndPointBehavior">
          <dataContractSerializer maxItemsInObjectGraph="2147483646"/>
        </behavior>
      </endpointBehaviors>
    </behaviors>

    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
  </system.serviceModel>

You need to set basicHttpBinding -> MaxReceivedMessageSize in the client configuration.
