Abstract: A proxy mobile station for retransmitting reverse channel signals from a mobile station to a base station of a wireless network. The proxy mobile station comprises: 1) a controller for receiving reverse channel data to be transmitted to the base station and transmitting the reverse channel data using an assigned mobile station identifier associated with the mobile station; and 2) a radio frequency transceiver for up-converting the encoded reverse channel data for transmission to the base station. The assigned mobile station is modifiable and may be modified by an external control device.

Abstract: Shear-thinning ethylene/?-olefin and ethylene/?-olefin/diene monomer interpolymers that do not include a traditional branch-inducing monomer such as norbornadiene are prepared at an elevated temperature in an atmosphere that has little or no hydrogen using a constrained geometry complex catalyst and an activating cocatalyst.

Abstract: A proxy translator for use in a wireless network. The proxy translator re-transmits forward and reverse channel signals between a base station and mobile stations. The proxy translator comprises a first proxy mobile station that communicate with a base station and a proxy base transceiver subsystem (BTS) that communicates with a first mobile station. The first proxy mobile station receives forward channel signals intended for the first mobile station and transfers them to the proxy BTS for re-transmission to the first mobile station. The proxy BTS receives reverse channel signals from the first mobile station and transfers them to the first proxy mobile station for re-transmission to the base station.

Preferably, the process comprises interpolymerizing a first homogeneous ethylene/alpha-olefin interpolymer and at least one second homogeneous ethylene/alpha-olefin interpolymer using at least two constrained geometry catalysts having different reactivities such that the first ethylene/alpha-olefin interpolymer has a narrow molecular weight distribution (NMWD) with a very high comonomer content and relatively high molecular weight and the second ethylene/alpha-olefin interpolymer has a NMWD with a low comonomer content and a molecular weight lower than that of the first interpolymer. The resultant first homogeneous interpolymer is combined with the resultant second homogeneous interpolymer in appropriate weight ratios resulting in the desired finished polymer structure.
