       Note 4. Segment Information and Major Customers, page 53

   1.                                                   We note your breakdown 
of industry sectors that are served by each operating segment for
                                                        both the IoT Product & 
Services (P&S) and IoT Solutions (Solutions) segments in
                                                        response to prior 
comment 2. Please tell us whether sales for any of the operating
                                                        segments included in 
each of your reporting segments are concentrated in a particular
                                                        industry sector or 
sectors, and if so, why. In your response, provide us with a breakdown
                                                        of revenue by operating 
segment for each industry served.
   2.                                                   We note that while the 
CODM    focuses    on operating income as a percent of revenue for
                                                        your P&S segments and 
gross profit margin for the Solutions segments, he receives both
                                                        of these measures, as 
well as revenue, for each of your operating segments. Please explain
                                                        how the CODM uses 
revenue for each of the operating segments, gross profit for the P&S
                                                        segments, and operating 
income for the Solutions segments. For example, clarify whether
                                                        he uses it to allocate 
resources, in discussions with segment managers, segment manager
                                                        compensation, etc.

3.       You state in your response the primary measure of profit used by your 
CODM to make
         decisions in your P&S segments is operating income as a percent of 
revenue, excluding
         certain allocations. However, there do not appear to be unallocated 
expenses in the
         measure of profit disclosed in Note 4. We also understand that your 
CODM receives each
         of gross profit and operating income for each of your operating 
segments. Please tell us
         how you determined the measure of profit or loss required to be 
disclosed for each of your
         reportable segments. Refer to ASC 280-10-50-22 and 50-28.
4.       You state in your response to prior comment 3 that pricing for the 
product sales in your
         P&S segments can be variable, and the mix of product sales plays a 
heavy factor and does
         not always have consistency over reporting periods. Please explain 
further your references
         to variable pricing and to the mix of product and their impact on 
consistency over
         reporting periods. In this regard, clarify whether you are referring 
to variability for a
         particular operating segment period-over-period. If so, provide us 
with quantified
         information that supports such variability. To the extent you are 
referring to variability
         among the four operating segments in a given period, if any, explain 
further why such
         information would not be relevant in assessing performance and 
allocating resources for
         your P&S operating segments. In addition, tell us whether similar 
impacts from these
         factors would be observed in operating income, and if not, why not.
5.       Please provide us with an analysis of available quantified data as it 
relates to revenue,
         gross profit, and operating income for each individual operating 
segment aggregated
         within your P&S and Solutions reportable segments.
6.       You state that operating income as a percentage of revenue in fiscal 
2021 and 2023 was
         similar for three of the four P&S operating segments. You further 
state that COVID-19
         had a more significant impact on one operating segment than the other 
three in the P&S
         segment. For the one segment you indicate was outside of the band of 
operating income as
         a percentage of revenue for each year, please explain why you believe 
it was impacted
         more by the COVID-19 pandemic, why you believe the other segments were 
not similarly
         impacted, and how this factored into your aggregation analysis. If 
this did not factor into
         your analysis, explain why. Also, provide us with quantitative 
information to support your
         assertions that historically this one segment has demonstrated 
economic similarity with
         the other three operating segments.
7.     You state that projected future performance for the P&S segments is not 
expected to
       change in a way that would impact your analysis other than in the one 
segment, and that

       projected future performance is not expected to change for the Solutions 
segments. Please
