Known Limitations

Coverage Maps:

• Coverage is not shown within hexes that fall on state borders
• Alaska is not included in the default coverage map (coming soon).
• Some networks report coverage more reliably than others. Coverage Critic makes rough corrections for the major networks, but there’s room for improvement.
• Reported coverage is taken at face value for Dish and US Cellular (accuracy adjustments coming in future versions)

Network Scoring:

• Networks vary in congestion levels. This is not adequately accounted for. Verizon would probably not score quite as well if the model adequately captured the consequences of congestion.
• The FCC data used for scoring networks is significantly out of date. Coverage Critic will soon move to a different approach that uses newer data.
• T-Mobile’s network has improved substantially in the last few years. This is not adequately captured (but hopefully will be soon).
• Numerical 0 to 10 scores are hard to interpret in concrete terms.
