Abstract: A system of radio frequency communication between Readers and Tags having a scalable Media Access Control (MAC) protocol for an active RFID system employing multiple access. The system comprising at least one tag Reader and a plurality of Tags each having a unique tag ID and deployed in a region in which at least some of the Tags are in radio communication with the tag Reader. A multi-dimensional addressing scheme of the MAC protocol enables division of the plurality of Tags into a number of groups for different stages of MAC protocol processing, based on different portions of the tag ID. The MAC has an inherent flexibility in the sense that it allows readers to communicate with different versions of tags and also optimize communication parameters to reader's capabilities, without pre-configuration of the tags. Furthermore, the MAC supports means to achieve very high access reliability, such as relay between tags.

Abstract: Methods to create a cellular-like communication system, such as a Wireless Private Branch Exchange (WPBX), which includes mobile devices such as standard cordless phones (handsets), particularly, mobile devices utilizing the Bluetooth short-range wireless communication protocol. The methods provide seamless and reliable handoff of sessions between Base Stations while the mobile device is moving between picocells, by implementing a high-level of synchronization between the Base Stations and the Switch. Base Stations of picocells having small coverage areas communicate with the handsets. The communication protocol is divided into a low-level protocol performed by the Base Stations and a high-level protocol performed by the Switch connected to all the Base Stations. The methods support mobile computing or telephony devices and communication protocols, which are not specified to handle handoffs of sessions while moving between Base Stations coverage areas in a data, voice or telephony wireless network.

Abstract: A method to allow standard cellular handsets and personal data devices that support short-range communication to seamlessly connect to a wireless private branch exchange (WPBX) when it is in its coverage range. Thus the handset will become the handset of the WPBX, and there is no need to use special and expensive handsets with the WPBX. The WPBX includes a plurality of Base Stations, a plurality of gateways—all connected by communication links—and the required communication between them is also described. The operating procedures that the Base Stations and the Switch perform are described. The WPBX allows handoff between cells, when a standard cordless handset is used. The handset does not support connection to more then one Base Station and does not support mobility. The handset uses complicated digital communication methods, so simple handoff methods that only the Switch supports are not sufficient.
