Problems solved by technology

Further, the combined effect of two or more simultaneously operating radios may cause intermodulation effects for another bandwidth due to harmonic effects
These perturbations may introduce errors that require retransmission of lost packets and an overall degradation of performance for one or more communication media
[0010] The use of communication devices with the ability to communicate over multiple wireless communication media would be severely hampered if only one of these communications could be used at a time

Embodiment Construction

[0034] While the invention has been described in preferred embodiments, various changes may be made therein without departing from the spirit and scope of the invention as described in the claims.

[0035] I. Wireless communication over different communication networks

[0036] WCDs can send and receive information over an array of wide-ranging wireless communication networks, each network having different advantages with respect to speed, range, quality (error correction), security (encoding), and the like. These characteristics will indicate the amount of information that may be transmitted to the receiving device, as well as the duration of that information transmission. Figure 1 includes a schematic diagram of a WCD and how it interacts with various types of wireless networks.

[0037] In the example shown in FIG. 1 , user 110 owns WCD 100 . The device can be anything from a basic cellular handheld to a more complex device, such as a wireless-enabled palmtop or laptop co...

Abstract

A system for managing the simultaneous operation of a plurality of radio modems in a single wireless communication device (WCD). The multiradio control may be integrated into the WCD as a subsystem responsible for scheduling wireless communications by temporarily enabling or disabling the plurality of radio modems within the device. The multiradio control system may comprise a multiradio controller (MRC) and a plurality dedicated radio interfaces. The radio interfaces are dedicated to quickly conveying delay sensitive information to and from the radio modems. This information may be requested by the MRC, or provided by one or more of the plurality of radio modems, if a change occurs during operation.

Description

[0001] Cross References to Related Applications [0002] This international application claims priority to US Application Serial No. 11 / 431,541, filed May 11, 2006, entitled "MULTIRADIO CONTROL INTERFACE," which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to a system for managing multiple radio modems embedded in a wireless communication device, and more particularly to a multi-radio control system for scheduling multiple active radio modems to avoid communication conflicts. Background technique [0004] Modern society is rapidly embracing, and becoming dependent on, handheld devices for wireless communications. For example, cellular telephones continue to increase in the global market due to technological improvements in both communication quality and device functionality. These wireless communication devices (WCDs) have become common for both personal and business use, allowing users to send and receive voic...
