摘要： A method for improving the display of the interaction between cells in wireless environment by a computerized site layout system is presented. Each cell has a cell boundary threshold signal level and a hand-off trigger threshold signal level. After the signal strengths of the cells throughout the environment are calculated, the signal strength data is examined to determine for a primary cell and each of its neighbor cells, in turn, a handoff region where the signal strength of said primary cell is at least equal to its cell boundary threshold signal level and the signal strength of the particular neighbor cells is at least equal to its hand-off trigger threshold signal level. The position of the primary and neighbor cells and the identified handoff regions are graphically displayed. Preferably, each cell is assigned a unique display indicium and the handoff regions are displayed using a combination of the indicia for the primary and respective neighbor cell.

摘要： A tree removal device configured for coupling on a working vehicle is usable for slicing tree roots. The working vehicle has a front element which is pivotal relative to a frame of the vehicle about a lateral axis in front of a forward end of the frame, thereby allowing a knife element of the tree removal device to be pivoted into the ground for performing a cutting action with a sharpened cutting edge so as to slice the tree roots.

摘要： A combination of a tree removal device and working vehicle for coupling the device thereon such that the combination is arranged for slicing tree roots. The working vehicle has a front element which is pivotable relative to a frame of the vehicle about a lateral axis in front of a forward end of the frame. The tree removal device includes an attachment portion for coupling to the front element and a knife element having a blade portion. The blade portion has front and rear edges arranged for engaging the ground in respective forward and backward directions of movement of the vehicle which are sharpened so as to perform a cutting action in the respective direction of movement when the blade portion engages the ground. Furthermore, the knife element is pivotable relative to the attachment about an axis in a vertical plane that divides the vehicle into symmetrical halves.

摘要： The present invention provides an apparatus and system for accurately predicting and evaluating cellular system performance before an actual system is installed at a site. In accordance with an embodiment of the invention, only two persons (or under certain conditions, as few as one) are required to operate the portable measurement and antenna placement (MAP) tools of the invention, and evaluate system performance (e.g., voice quality) at varied locations of a site without the system being in place. A user can measure out the size of cells using a bar graph display that shows the range of acceptable signal levels for the system, and an audible warning tone that signals the user when the cell edge has been exceeded. In addition, other quality determinative system parameters (e.g., bit error rate (BER), etc.) can be evaluated simultaneously with voice quality and average received signal strength.

摘要： The present invention provides a method and apparatus for transmitting a synchronization beacon from a wireless base station to a wireless terminal in a wireless communication network installed in a building. The wireless network comprises a private branch exchange (PBX) connected to a wireless fixed base station (WFB) having a plurality of cell antennae units (CAUs) connected thereto. In a first embodiment, the plurality of CAUs are located in a single cell of the wireless network and are configured to receive two synchronization beacons from the WFB. In a second embodiment, each CAU is located in a separate cell in the network and is configured to receive a single synchronization beacon from the WFB. The synchronization beacon(s) is/are managed by the WFB and WT to virtually eliminate loss of synchronization between the WFB and WT if the frequency-timeslot at which the beacon is transmitted is changed or if transmission of the beacon is temporarily discontinued. In addition, synchronization between the WFB and WT is also maintained when the WT is moved to another cell in the wireless network.
