Description

OTREC-RR-10-16This project pursued implementation and testing of a Bluetooth (BT) travel time data collection system, including comprehensive testing of all components. Two different BT based systems were installed. The first, composed of two DCUs, was installed on a corridor in Salem, OR. Extensive testing was done here, including collection of travel time samples. A second system of five DCUs was installed along 99W in Tigard, OR. Very limited data was collected

This project pursued implementation and testing of a Bluetooth (BT) travel time data collection system, including comprehensive testing of all components. Two different BT-based systems were installed. The first, composed of two DCUs, was installed on a corridor in Salem, OR. Extensive testing was done here, including collection of travel time samples. A second system of five DCUs was installed along 99W in Tigard, OR. Very limited data was collected here due to lack of network connectivity.
Six different antenna types were characterized using the two DCU BT-based data collection system. The result of the characterization tests showed that vertically polarized antennas with gains between 9 and 12 dBi are good candidates to support a BT-based system. Travel time samples were also collected with this system. The results indicate that a trade-off exists between the number of samples obtained and the accuracy of the samples, most likely due to differences in coverage areas provided by the different antennas.

AWESOME Look and Quality
Color: Brown, Size: 2Tier60in
I love these shelves and have bought additional for other areas in the house. I love the look of the industrial pipes, the color of the shelves is perfect, they are sturdy and hold a lot of weight. They are somewhat difficult to assemble, but it's expected as hanging shelves are never fun to hang. I love them. If you are on the fence, just do it :)

Nice, but a bear to install
Color: Black, Size: 3Tier48in
Quality product that looks good on our shiplap wall of the wet bar space. The install was a real trip and extremely difficult. You definitely need 2 or more people to install as the direction tell you to put the entire item together, then hang on the wall. This makes it impossible to do yourself.

Exactly what I was looking for
Color: Brown, Size: 3Tier48in, Color: Brown, Size: 3Tier48in
Very sturdy shelves and super easy to put together. I would put the shelves together starting with the bottoms then after it’s put together tighten everything up also starting from the bottom.

Great buy
Great shelf base! The price is great and it does the job. I just got the actual shelves from Lowe’s and they work great. I used for my teen son’s room and he loves them!
