In another embodiment, a base unit of a cordless telephone is made a member of a first wireless piconet network while its remote handset is made a member of a second wireless base unit, and piconet content information is passed from a device on one wireless piconet network to another device on the other wireless piconet network over the wireless cordless telephone (e.g., 900 MHz or 2.4 GHz range) channel established between the cordless telephone base unit and its remote handset.

A method for providing a local cordless-type service comprises the steps of receiving subscriber neighborhood zone selection input so that a mobile telephone equipped subscriber may place or receive calls for a fixed rate, for example, per month without having to pay radio frequency air time charges any time they are located within their selected subscribed-to zones. If the subscribed-to zones are adjacent to one another and the mobile subscriber roams from one zone to another, the subscriber may continue their free call uninterrupted and without paying air time charges. However, when the subscriber roams outside their subscribed-to zones they may be switched from the present local cordless-type services to conventional personal communications services and pay air time charges. However for an active call, no air-time charges are incurred as the user transitions between the cellular / DPCS environment and the local cordless service environment. Associated apparatus comprises an IBS for automatically changing radio frequency channels as the subscriber roams within a subscribed-to neighborhood zone, roams to another subscribed-to zone or roams outside a subscribed-to zone. Subscribers may choose to use their mobile identification number, their current directory telephone number for wired public switched telephone service or obtain a new directory number. Subscribers can actuate their service over-the-air automatically without service personnel assistance from their home neighborhood zone.

A novel and useful apparatus for and method of determining the channel order and channel estimate in a communications system such as a wireless communication system including cellular and cordless. Such channels are typically characterized by rapidly changing impulse response and their taps can be modeled as zero-mean, complex, Gaussian random processes. A sufficiently long, initial channel estimate of length is performed so as to ensure that the actual channel taps will be contained in the estimated taps thus making certain that the equalizer will effectively eliminate intersymbol interference. Channel estimation is performed during each burst using the training sequence transmitted in the middle of the burst. The tap energies are averaged so as to track slow variations in the pattern of resultant channel taps. A noise floor is calculated using the lowest averaged taps and a threshold is computed based thereon and applied to the average taps. The channel order and the tap positions are then selected in accordance those average taps that are above the threshold.

A means for charging the battery of a battery powered tool or device automatically, as said device is used is disclosed. A battery operated device, such as a cordless power tool, can have its battery re-charged without using a AC plug-in type battery charger. This can be accomplished by installing a DC charging component, as a permanent part of the said device. The said charging component is installed in such a manner that the same motor that operates the said device, also energizes the said charging component. The power generated by said charging component, is then transmitted to said battery via a voltage regulating device. The process thus mentioned eliminates the need for a separate charging device for normal operation. This makes said tool or device more convenient to use, thus eliminating the gradual loss of power associated with conventional cordless power tools. This device will also save time and money to consumers. Another aspect of this invention is the establishment of a standardize, universal battery system which will create uniform battery standards world-wide for industries.
