Sae Young Chung, M Vedat Eyuboglu, Yong Hoon Kang, Dae Young Kim, Jin Hwa Ku, Seung Hee Lee, Michael D Pollman: Capacity enhancement schemes for forward and reverse links of distributed cellular base stations. Airvana, Solid Technologies, Fish & Richardson P C, April 3, 2007: US07200391 (299 worldwide citation)

Capacity enhancement schemes are described for forward and reverse links of distributed cellular base stations consisting of a central unit and one or more remote units. In general, in one aspect, reverse link capacity is shared among remote units. The capacity sharing can be determined dynamically. ...

Michael D Pollman, Theodore O Grosch: Providing global positioning system (GPS) timing signals to remote cellular base stations. Airvana, Fish & Richardson P C, July 7, 2009: US07558356 (55 worldwide citation)

In a cellular network, a GPS receiver includes circuitry that modulates a global positioning system (GPS) timing pulse signal with a carrier signal and transmits the modulated signal to one or more remote base stations. When the modulated timing pulse signal is received at a remote base station it i ...

Michael D Pollman, Satish Ananthaiyer, Theodore O Grosch: Measuring interference in radio networks. Airvana, Fish & Richardson P C, November 9, 2010: US07831257 (27 worldwide citation)

In a radio access network (e.g., a cellular network), a radio receiver is configured with a switch that alternatively couples an antenna and an impedance-matched load to the remainder of the receiver. Sector load, e.g., rise-over-thermal (ROT), is monitored by comparing a first measurement of signal ...

William L Pribble, Michael D Pollman, Roger D Sweeney: Method and apparatus for testing circuits containing active devices. ITT Corporation, Arthur L Plevy, Patrick M Hogan, April 4, 1995: US05404109 (8 worldwide citation)

A test system for measuring the characteristics of an active circuit employs a pulsed bias technique for periodically biasing the input control port of the active circuit into the active region of operation. Biasing is achieved with a bias voltage that is periodically pulsed ON and OFF. An RF source ...

David A Willems, Edward L Griffin, Inder J Bahl, Michael D Pollman: High efficiency harmonic injection power amplifier. ITT Corporation, Arthur L Plevy, December 15, 1992: US05172072 (7 worldwide citation)

A high efficiency harmonic injection power amplifier has a power amplifier circuit, and at least a second-harmonic termination circuit which is coupled in parallel with the power amplifier circuit so to sample a small portion of the input signal and to inject into the power output signal an amplifie ...

Capacity enhancement schemes are described for forward and reverse links of distributed cellular base stations consisting of a central unit and one or more remote units. In general, in one aspect, reverse link capacity is shared among remote units. The capacity sharing can be determined dynamically. ...
