Doodle Labs maintains a network of cost effective EMS partners with state-of-the-art manufacturing equipment and ISO certified processes to rapidly get the design into high volume manufacturing. Below are few examples to illustrate Doodle Labs capabilities. 

5 Gbit/s Wireless Communication System

This is a ground-breaking applied research project for a tier 1 telecommunication company in Japan. The customer needed to evaluate possibilities and alternatives for the next generation of cellular phone communications after 5G (“6G”). The objective was to use 500 MHz of contiguous frequency in the 4 GHz band to achieve the maximum data transmission rate at 100 meter range. Doodle Labs team decided to leverage the high data rates of the IEEE 802.11ac technology for this project. 12x channels (each 40 MHz wide) were bonded and frequency shifted to achieve a very fast wireless transmission system. A very challenging assignment indeed but Doodle Labs team exceeded the customer’s expectations. 

 

LTE-TDD in 3.5 GHz CBRS Band

Prior to FCC releasing the 3.5 GHz band as Citizen’s Band Radio Service (CBRS),  a tier 1 LTE equipment manufacturer needed to do field trials and demonstrate the co-existence in this shared spectrum. Doodle Labs developed a 2×2:2 MIMO eFES (Front-End Subsystem) to attach to the customer’s existing LTE small cell (2.5 GHz, Band 41) and transpose the wireless signals to this target band. Additionally, Doodle Labs used the IEEE802.11n radio and eFES for a 3.5 GHz Prism-WiFi transceiver. Doodle Labs has commercialized these developments and now available for a wider customer base. 

 

Frequency Shifted WiFi for Disaster Recovery Robots

After the major Tsunami disaster in 2011, the Japanese government decided to develop an army of Robots that can perform various disaster recovery tasks amongst the rubble of fallen buildings. It was recognized that the robots require high throughput C3 wireless links with deep penetration capabilities. To help with the penetration issues, the government allocated a special 5 MHz wide low frequency band at 190 MHz for this application. Doodle Labs was asked to custom design a transceiver for this special frequency band.
