Current Use Cases
• For the last year, Carlson has shipped nearly 2000 radios to 38 countries around the globe.
• The type of use cases vary from curious microphone companies to oil and mineral, public safety, railroads for PTC, municipal wireless, backhauling hotspots in Africa, US WISPs as well as WISP’s in many other countries.
• Following is a couple of the entrants into new verticals:
Use Case Demonstrating NLOS
• McKinleyville case
Traction in the Industry• Alaska Railroad
• 470 Miles of Track
• Used to backhaul PTC
• Fairbanks to Seward
• Runs passenger service daily
Public Safety – Police Dept.• Peru, IN Police dept
• 30 Cars equipped with TVWS clients
• Nomadic up/down data transfer
• Big cost reduction from cellular costs
Next Gen - Unlocking the Market
• The last 4 years, Carlson Wireless has been surveying global regulators and service providers.
• Summations from these discussions are that the TV white space market is held back mainly due to price-performance metrics and standardization.
• We believe the solution to unlocking the NLOS market is met by offering a product meeting the price and perf. of current microwave products.
