As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.
Information handling systems, and in particular mobile information handling systems, often use wireless networking interfaces to communicate through wireless networks. The wireless networks support a variety of different protocols over a variety of different frequencies and communication ranges. One example of such wireless networks is the wireless wide area networks (WWAN) used by mobile (cellular) telephones, such as 3G and 4G mobile broadband. WWAN networks typically use licensed frequency bands assigned to particular network providers. Another example of such wireless networks is the networks that operate in the unlicensed frequency bands. For instance wireless local area networks (WLAN) use the 2.4 GHz and 5 GHz frequency bands to support shorter range communications typically restricted to a home, office, or retail “hot spot” location. WLAN networks also support peer-to-peer device connectivity for adjacent devices and peripherals. Other unlicensed networks typically used for short range device and peripheral connectivity include Bluetooth and 60 GHz WiGig. Some wireless network devices only receive data, such as GPS and television receivers. Others operate over extremely short ranges, such as near field communication (NFC) devices.
One difficulty faced by information handling system manufacturers is adapting systems to include new wireless devices as such devices become available. For example, future wireless communications systems may include broadband wireless access known as White Space Spectrum, real-time multimedia services, DVB-H/FLO/DMB-T mobile television, 802.20 Flash OFDM and WiMax. Adding additional integrated wireless devices into existing portable information handling systems presents substantial electrical and ID design challenges. Consumers who purchase portable information handling systems generally want the lightest and most streamlined form-factor platforms; however, placing multiple radio and antenna structures in a device typically involves a considerable footprint in order to obtain acceptable performance with each device. Each radio and antenna structure has mechanical constraints for the placement of components, electrical constraints for powering the components and thermal constraints to ensure that the system operates at acceptable temperatures. Radio performance depends upon antenna placement and tuning as well as the material used in the device platform. Further, passing required emissions testing with minimal signal interference and antenna coupling tends to further restrict design alternatives for adding radio and antenna structures. EMI emissions and regulatory compliance varies worldwide, which introduces other design challenges. In addition, end users probably will not desire all possible radio configurations in every system so that different housings may include different structures that introduce difficulties in the manufacture process.
