The present invention relates generally to the field of wireless communication. In particular, the present invention relates to a wireless communication devices configured to accommodate a second wireless communication device.
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is rapidly improving, the cards within the systems as well as the interfaces supporting them also have become outdated.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.
In one aspect, a system for wireless communication comprises a first communication device having a first interface for interfacing with a host device and a second interface; and a second communication device configured to be coupled to the second interface of the first communication device. The first communication device and the second communication device, when coupled, form a substantially integrated device.
In one embodiment, the substantially integrated device has a substantially rectangular profile.
In one embodiment, the first communication device has an enlarged portion at one end. The enlarged portion of the first communication device may include an antenna element.
In one embodiment, the second communication device includes an enlarged portion that is congruent with the enlarged portion of the first communication device when the first communication device and the second communication device are coupled. The enlarged portion of the second communication device may include an antenna element. The enlarged portion of the second communication device may include an LED, wherein the LED is operable during data transfer. The enlarged portion of the second communication device may include a finger print detection module, the finger print detection module being operable to give access to wireless communication within the system. The enlarged portion of the second communication device may include an adapter for connection to one of serial ATA (SATA), Firewire, memory card, Ethernet, SmartCard, or serial port.
In one embodiment, the first interface is configured to be coupled to a computing device.
In one embodiment, the first interface comprises a universal PC Card connector.
In one embodiment, the first interface comprises an ExpressCard connector. In one embodiment, the second interface is one of Universal Serial Bus (USB), USB 2.0, Firewire, PCI Express serial, SmartCard, or Subscriber Identification Module (SIM).
In one embodiment, the first communication device comprises a wireless modem.
In one embodiment, the second communication device comprises an ExpressCard module in accordance with PCMCIA standards. The ExpressCard module may comprise one of a tuner, adapter or reader.
In one embodiment, the first wireless communication device includes a memory element.
In one embodiment, the first communication device has a non-conductive material lining on an inner wall interfacing the second communication device when coupled. The lining may contain a slot for securing placement of the second wireless communication device.
In one embodiment, the first communication device is configured to intercept one or more wireless signals types.
In another aspect, a wireless communication adapter for a wireless communication device comprises a body; a first interface for interfacing with a host device; and a second interface configured to be coupled to a second communication device. The body is configured to form a substantially integrated device with the second communication device when the second communication device is coupled with the second interface.
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.
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.
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.
Referring to
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.
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.
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.
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
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
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
Referring now to
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.
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.
