GRS-1915D-SPR is a 3G Indoor repeater, which has been designed to improve signals in

blanket/shadow areas inside of buildings to transmit Sprint signals at PCS 1900MHz band.

Characteristics

PCS Band: 72dB Gain with 15dBm maximum composite output power.

Bandwidth: Entire PCS 1900 frequency A Block to F Block (45MHz). Bandwidth selection

adjustable per user’s situation.

5MHz, 10MHz, 15MHz Blocks

Three continuous 5MHz, 10MHz, 15MHz block combinations ( only continuous )

See page 10 for more details.
