Abstract: A multiple radar on chip based system is disclosed in the present invention which mainly comprises a ramp generator which is configured to input and process a digital signal and convert it into a digital ramp signal. The fractional-N PLL synthesizer receives the digital ramp signal from the ramp generator and compares it with reference input signal to provide analog RF ramp signal. A frequency multiplier is provided to receive the analog RF ramp signal from the fractional N-PLL synthesizer and generates a local oscillator output signal which is sent to a plurality of receiver chains as output signal. These receiver chains receive amplified analog signal input from the power amplifier also as an output and then after comparing the frequency of local oscillator output and amplified analog signal input, final output is processed. The ramp generator and fractional-N PLL synthesizer may be off chip.

Abstract: A gateway for mobile access includes a foreign agent that receives user profile data and session state data from a home authentication, authorization and accounting (AAA) system of a mobile node, and a dynamic packet filter that performs multi-layer filtering based on the user profile data. The foreign agent transfers a session from a first network to a second network without session interruption, using the session state data, when the mobile node moves from the first network to the second network. The packet filter permits Internet access by the mobile node without passing Internet data requested by the mobile node through the first network.

Abstract: A gateway for mobile communications comprises a cache for storing network data recently downloaded from a network, a foreign agent, and a packet filter that directs requests for the network data from a mobile node to the cache. The packet filter directs the requested network data from the cache to the mobile node by way of the foreign agent, without forwarding the requested network data to a home agent of the mobile node.

Abstract: A scheme for authentication, dynamic key generation and exchange provides means for authentication of mobile nodes and networks, and for generation of per session, per node, security association and encryption keys for encrypting/decrypting communications between a mobile node and an access point in wireless local area networks. The scheme utilizes the same infrastructure and authentication information for both data link layers (layer 2) and network layers (layer 3). This scheme is particularly applicable to networks adhering to the IEEE 802 LAN family of standards.

Abstract: Portable and/or mobile IP hosts desiring to connect to the Internet can dynamically acquire a home address and other configuration information through DHCP when powering up in a foreign network. A two-stage configuration procedure is used. First, the mobile host uses the M-IP protocol to establish contact with an addressing element, referred to as a bootstrapping agent, that is usually co-located with a M-IP Home Agent, and that allocates a temporary home address for the mobile host. The temporary address is used to create a temporary tunnel. Second, this temporary tunnel is used as the communication vehicle over which standard DHCP transactions take place. The present invention is thus arranged to use a) M-IP as the signaling mechanism for reaching the home network and dynamically allocating a temporary home address for the mobile host; and b) DHCP to allocate a permanent home address and any other configuration state for the mobile host.
