Patent number: 6912409Abstract: An improved modular masthead for use in cellular communications networks is described. The masthead unit includes a power amplifier, a duplexer and a local power supply that supplies the power amplifier. The power amplifier is arranged to amplify outgoing communication signals received from a base station. In a preferred embodiment, the masthead also includes a low noise amplifier for amplifying incoming communication signals and passing the amplified incoming communication signals to an associated base station. With this arrangement, the masthead forms a modular unit that is distinct from the base station such that the modular masthead may be replaced independently of the base station. With this arrangement the range of a cell within a cellular network may be changed by simply swapping an existing masthead unit with a second masthead unit having a different power supply thereon and making software changes in the system.Type: GrantFiled: June 8, 2001Date of Patent: June 28, 2005Assignee: InterWAVE Communications International, Ltd.Inventor: Nicholas S.

Patent number: 6847653Abstract: The present invention is a communications protocol which provides for voice and data priority channels in order that both voice and data information have equal opportunity to transmit over a communications network. This is achieved by splitting the 25 millisecond FCC dwell time into two 12.5 millisecond halves, and dedicating one half to voice packets and the other half to data frames. In the voice priority channel, the frequency hopping interval is doubled. Additionally, both channels operate independently, each maintaining independent bidding, data transmission, acknowledgement and retransmission. Pad packets are used to insure voice channel connectivity.Type: GrantFiled: April 19, 2000Date of Patent: January 25, 2005Assignee: Interwave Communications International, Ltd.Inventor: Michael Smiroldo

Patent number: 6169907Abstract: A first communication device is in communication with a second communication device. The communication may be characterized by a first and a second characteristic that are affected by a transmit power of the first communication device, each characteristic having an upper and a lower bound. The transmit power of the first communication device is delayed from being adjusted to bring the communication within the upper and lower bounds of the first criteria and outside the upper and lower bounds of the second criteria when a contrary adjustment of the transmit power of the first communication device was performed until a predetermined amount of time has expired since the contrary adjustment. Thus, unnecessarily repetitive power adjustments are avoided.Type: GrantFiled: October 21, 1997Date of Patent: January 2, 2001Assignee: interWAVE Communications International Ltd.Inventors: Yu-Wen Chang, Pi-Hui Chao
