Jarvinian, Globalstar eye Silicon Valley for tests of TLPS private Wi-Fi service

Jarvinian Wireless Application Fund has filed a second application for an experimental license to test a terrestrial low-power service (TLPS) that could be used for a private, licensed Wi-Fi service operating over Globalstar's spectrum and unlicensed ISM band spectrum.

The new application filed with the FCC would cover tests at three locations across California's Silicon Valley, specifically in the cities of Sunnyvale and Cupertino. Jarvinian previously applied to conduct TLPS tests in Cambridge, Mass., where the fund is headquartered.

Jarvinian has been working with Globalstar for two years. Globalstar is licensed to provide mobile satellite service in the Big LEO band at 1610-1618.725 MHz (the Lower Big LEO band) for uplink operations and 2483.5-2500 MHz (the Upper Big LEO band) for downlink operations. The companies envision creating a TLPS network operating in the upper 2.4 GHz band and also making use of adjacent unlicensed industrial, scientific and medical (ISM) spectrum at 2473-2483.5 MHz.

"The proposed Terrestrial Low Power Service (TLPS) would use 11.5 MHz of Globalstar S-Band spectrum paired with approximately 10 MHz of upper ISM spectrum to effectively enable the previously unusable 802.11 Channel 14 as a managed wireless service offering. This proposal is significant, since TLPS would mean a fourth orthogonal 802.11 channel in the extremely overcrowded and interference limited 2.4 GHz band," said Jarvinian in its most recent license application.

Consulting engineer Steven Crowley wrote in his blog that the California tests would use different equipment than the one planned for Massachusetts. "The Cambridge application specified 50 Linksys WRT54GL access points, 10 Ubiquity UniFi access points, 10 Ubiquity XR2 client cards and 10 Ubiquity SR-71-12 client cards. The Silicon Valley application specifies 10 TP-LINK TL-WA5110G access points, 20 TP-LINK TL-WR1043ND access points and 20 Ubiquity SR-71-12 client cards," he said.

Jarvinian filed its Silicon Valley experimental license application on March 6 and the Cambridge application on Feb. 13.
