1 2 3 4 Grant CommentsOutput power listed is ERP for operations below 1 GHz, EIRP for operations above 1 GHz. This device supports bandwidths of 1.4 MHz in LTE Bands 2 (1850-1910 MHz), LTE Band 4 (1710-1755 MHz) and LTE Band 12 (699-716 MHz). Powers listed are for the highest power and widest bandwidth within each band for QPSK and 16QAM modulations. Grant lists the widest bandwidths and bandwidths with the highest power for each emissions designator in each LTE band. For satisfying FCC RF exposure compliance requirements, this transmitter must be installed to provide at least 20 cm separation between the device and the user's body. This device contains functions that are not operational in U.S. Territories; filings under this FCC ID are approved only for U.S. operations.
1 2 3 4 Listed output power is peak conducted. This device supports 802.11b, 802.11g and 802.11n with 20MHz Bandwidth. This device also supports 915MHz. This transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. End-users and installers must be provided with transmitter operating conditions for satisfying RF exposure compliance. Antennas used with this device must be of the same type with gains equal to or lower than described in this filing.
