BACKGROUND OF THE INVENTION

[0002] Network access has generally been limited to wired connections such as dial- up and Ethernet. In addition, users have typically had to subscribe to internet service providers (ISPs) which provided service solely over local area networks (LANs). However, as the demand for mobility increases, wireless technology has emerged. At first, wireless connectivity was developed in the form of external components, such as PCMCIA (PC) cards in order to accommodate computing systems already available to consumers. Of course, such cards were built to accommodate the interfaces of these computing devices, with the 68 pin dual row connecting interfaces being an industry standard. Then, newer computing systems began to incorporate these cards and wireless connectivity to diminish the need for extraneous devices. However, as wireless technology is rapidly improving, the cards within the systems as well as the interfaces supporting them also have become outdated. Thus, current systems on the market cannot support the best wireless technology.

DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS

[0024] Newer wireless systems may need to support not only several wireless interfaces, but also several modes of wireless connectivity. This is due to the emergence of improving and faster wireless network technology. For example, wireless wide-area network (WAN) standards such as GPRS offer reasonable service quality at an affordable price and have relatively wide coverage. Unfortunately, for many high data rate applications, existing WAN technologies are too slow and expensive. On the other hand, wireless local area network (WLAN) running off the traditional LAN standards such as IEEE 802.11 have proven superior for use in localized data applications. LANs are faster, cheaper, and consume less power than their WAN counterparts. However, for all practical purposes, a mobile subscriber is not afforded continuous WLAN coverage throughout the day or in all geographic areas. WLAN or LAN coverage available to a subscriber at work does not usually extend to the subscriber's home or other locations where the subscriber may be located. Therefore, it would be advantageous to provide a subscriber a way to connect to a network in any location without having to buy or utilize various communication devices.

[0025] Accordingly, there is a need to incorporate such capabilities into prior computing systems, without have to re-design them. Thus, there is a need for the current systems to be able to support various modes of accessing differing wireless networks. Currently, a user wishing to gain access to multiple systems will often carry at least two devices, each device supporting a different system (WLAN/LAN, WAN). For example, a personal computer capable of supporting a wireless modem for Institute of Electrical and Electronics Engineers (IEEE) 802.11 access and a personal digital assistant (PDA) or cellular telephone for access to a wireless broadband network such as GPRS, EDGE or GSM. Manufacturing a multitude of modem devices dependent on interface and network type greatly increases manufacturing costs. Therefore, the market would benefit from a single modem device that could conform with a standard form factor and that comprises the technology required to access a plurality of communication systems.

[0026] Embodiments of the present invention pertain to a communication device which may be coupled with a second communication device for wireless communication, for example, over a network and through usage of a computing device. In one embodiment, a first communication device, which may be an adapter and may include an antenna element, has an L-shaped body with a rectangular area open for receiving an ExpressCard or other communication device. A rectangular ExpressCard may reflect symmetry both alone and when coupled with the adapter. When the adapter and the ExpressCard are coupled, a substantially integrated device is formed. In this regard, "substantially integrated" refers to the appearance of the device formed by the coupling of the adapter and the second communication device, such as the ExpressCard.

[0027] Referring to FIG. 1, a top view of an adapter 101 in accordance with an embodiment of the present invention is illustrated. In the illustrated embodiment, the adapter 101 has a body with an L-shape configuration with a base portion 103 and an arm portion 106. The base portion 103 is defined by an interior portion 107 for receiving a second communication device, and an exterior portion 108 with an interface 102. The interface 102 is configured to couple the adapter 101 to a host device (not shown) such as a personal computer (PC), a laptop or another communication device. The interface 102 may be a PCMCIA (PC) card connector, conforming to industry standard Type I, II, III or IV card slot (16-bit or 32-bit ISA bus interface) or an ExpressCard connector, USB connector, or similar connector for use with a computing device port, for example. The interior portion 107 of the base portion 103 may also include an interface for electronically coupling the second communication device received therein. The interface on the interior portion 107 may be any type of interface, such as ExpressCard, subscriber identification module (SIM) card, Universal Serial Bus (USB), USB 2.0, Firewire, PCI Express serial, SmartCard, or mini SIM.

[0028] The arm portion 106 of the adapter has an inner portion 105 which may be lined with plastic, rubber, or a similar type of non-conductive material for protection of the arm portion 106. This lining may also serve to secure placement of the second communication device when coupled to the interior portion 107. Accordingly, the lining along the inner portion 105 of the arm portion 106 may be ridged or slotted to form an inner channel, or slot area, to receive a portion (or edge) of the second communication device. Similarly, the interior portion 107 of the base portion 103 may include a protective layer of a non-conductive material as well. The interior portion 107 of the base portion 103 may be configured with a slot portion which includes the above-described interface for receiving an ExpressCard or other detachable device.

[0029] One end of the arm portion 106 may include an enlarged portion 104. In this regard, the enlarged portion 104 has a top surface which is raised relative to the remainder of the arm portion 106 and the base portion of the adapter 101. The enlarged portion 104 may only include a small portion of the arm portion 106 and may be configured to enclose an antenna for receiving wireless communication signals from varying networks, for example. The enlarged portion 104 may be larger or smaller, depending on the size necessary for the antenna element.

[0030] In one embodiment, the interface 102 of the exterior portion 108 is a PC connector, and the interface of the interior portion 107 is an ExpressCard interface. FIG. 2 illustrates an example of a second communication device which may be received in the interface of the interior portion 107. In various embodiments, the second communication device 201 to be received in the interior portion 107 may be an ExpressCard module in accordance with PCMCIA standards. In other embodiments, the second communication device 201 may be a subscriber identification module (SIM) card, mini-SIM card, memory card, SmartCard, or similar type of information card and/or communication device that may be interfaced with the first communication device, or adapter 101 illustrated in FIG. 1. [0031] In one embodiment, the second communication device 201 includes an interface 202 for electronically coupling the second communication device 201 to a communication device such as the adapter 101 (or first communication device) described above with reference to FIG. 1. The interface 202 of the second communication device 201 may be configured to be complimentary to the interface of the interior portion 107 of the adapter 101 of FIG. 1 or of any other first communication device with which the second communication device 201 is desired to be coupled.

[0032] In one embodiment, the second communication device 201 includes an enlarged portion 203. The enlarged portion 203 may be configured to compliment a corresponding enlarged portion of a first communication device with which the second communication device 201 is desired to be coupled. For example, the enlarged portion 203 of the second communication device 201 may complement the enlarged portion 104 of the adapter 101 of FIG. 1. The enlarged portion 203 of the second communication device 201 may include a secondary antenna element capable of receiving a wireless network signal. In other embodiments, the enlarged portion 203 of the second communication device 201 may include a fingerprint detection module configured to give a user access to a specific wireless communication network or access to the second communication device 201, for example. In yet another embodiment, the enlarged portion 203 may include an LED that is active, or lit, during transmission of data through either the first communication device or the second communication device 202. Further, the second communication device 201 may include a secondary adapter having a module (not shown) capable of receiving a serial ATA (SATA), Firewire, memory card, Ethernet, SmartCard, or serial port located at the top raised portion 203.

[0033] In addition, the second communication device 201 may include plastic, rubber or another type of non-conductively lined edge portions 204, similar to that of the material lining the inner portion 105 of the arm portion 106 of the adapter 101 of FIG. 1. The edge portions 204 of the second communication device 201 may include a singular notch portion for being received by the ridged, slot portion of the inner portion 105 of the arm portion 106 of the adapter 101. [0034] Referring now to FIGS. 3 and 4, a system including the adapter 101 coupled to the second communication device 201 is described. FIG. 3 illustrates a side view of the adapter 101 coupled to the second communication device 201 to form a substantially integrated device 301. FIG. 4 illustrates a frontal view of the substantially integrated device 301. In one embodiment, such as the embodiment illustrated in FIGS. 3 and 4, the second communication device 201 and the assembled integrated device 301 reflect similar symmetry. Accordingly, the adapter 101 and second communication device 201 are of approximately the same thickness throughout the bodies of the each, as well as at the enlarged portions 104, 203. One end of the assembled integrated device 301 includes the interface 102 of the adapter 101 for interfacing with, for example, a host device. The interface 102 may include allow connection to a 16- or 32-bit bus. As illustrated in FIGS. 3 and 4, one or both of the enlarged portions 104, 203 may include an antenna element for wireless communication. In other embodiments, the enlarged portion 203 of the second communication device 201 may include an LED which becomes visible during data transmission. Alternatively, the enlarged portion 203 of the second communication device 201 may include a secondary adapter for Ethernet, SD card, mini SD card, serial port, or similar port interface. In another embodiment, the enlarged portion 203 of the second communication device 201 may include no internal elements and may only be enlarged so that, when the second communication device 201 is coupled with the adapter 101, the enlarged portion 203 is congruent with the enlarged portion 104 of the adapter 101, or first communication device, in order to provide symmetry and to form a substantially integrated device.

[0035] Accordingly, in accordance with the illustrated embodiment, the second communication device 201, which may be an ExpressCard, is fitted within the L- shaped form of the adapter 101 against the lining material 105 of the arm portion of the adapter. The lining material 105 of the adapter 101 may include a ridge, or slot region, for secure placement of the second communication device 201 within the adapter 101. The interface portion 202 of the second communication device 201 also securely fits for coupling with the interface 107 of the adapter 101. Further, the receiving interface 107 of the adapter 101 may be within a slot or gap region of the adapter for secure placement and fitting of the second communication device 201. Thus, for congruence, the interface portion 202 of the second communication device 201 may be slightly thinner in width than the remaining central portion of the device. The interface may be an ExpressCard, SIM card, USB port, or a similar interface. When assembled, the adapter 101 and second communication device create a flush surface throughout the body and at the enlarged portions 104, 203 to form a substantially integrated device.

[0036] Thus, in accordance with embodiments of the present invention, the substantially integrated device 301 formed by the coupling of the adapter 101 and the second communication device 201 may be substantially rectangular in shape, similar in symmetry to an ExpressCard. In various embodiments, the "substantially rectangular" configuration may include variations, such as a decorative design across or a curvature across one edge of the substantially integrated device 301. The enlarged portions 104, 203 of the adapter 101 and the second communication device 201 may be flat while the two devices are flush when coupled. In one embodiment, the interface 102 of the adapter 101 may be a PCMCIA (PC) card connector, conforming to the industry standard Type I, II, III or IV card slot (16-bit or 32-bit ISA bus interface) or an ExpressCard connector, USB connector, or similar connector for use with a computing device. Accordingly, in one embodiment, when the adapter 101 and the second communication device 201 are coupled, the substantially integrated device 301 forms a complete PC card.
