The FCC and Canadian regulator Industry Canada agreed through "an exchange of letters" onn10 interim spectrum sharing arrangements covering operations along the border between the twoncountries. "These arrangements will aid in the deployment and use of mobile broadband and improvenpublic safety communications along the U.S.-Canada border by facilitating the efficient sharingnof spectrum and avoiding potential interference," the FCC said (http://bit.ly/YHvNpz). Thenagreement relies on contention-based protocols, which "allow multiple users to share the same spectrumnby defining the events that must occur when two or more devices attempt to simultaneouslynaccess the same channel and establishing rules by which each device is provided a reasonable opportunitynto operate," the FCC said. An agreement on the 3650-3700 MHz band "allows wirelessnbroadband and high-speed Internet services to coexist along the U.S.-Canada border," the agencynsaid. "Technical sharing arrangement reached on the 700 MHz band will allow public safety licenseesnon both sides of the border to fully implement their 700 MHz narrowband systems." The agreementsnalso cover PCS and AWS spectrum, the 4.9 GHz public safety band and spectrum used fornrailway communications systems.
