   BACKGROUND OF THE INVENTION 
   The present invention generally relates to communications systems and methods and, more particularly, relates to wireless packetized data communications providers and services and systems and methods therefor. 
   Wireless packetized data communications are becoming increasingly common. For example, certain cellular telephones can presently receive and display limited textual content. Some pagers presently have limited text messaging capabilities. Wireless modems can equip computing devices, such as laptop computers, personal digital assistants, and the like, for communicating over networks, such as the Internet, through wireless channels. 
   The presently available wireless packetized data communications are all severely restricted in capabilities because of bandwidth limitations of wireless channels for the communications. Conventional wireless modems typically communicate at about 9600 bits/second. Only small quantities of information can be communicated at such rate within reasonable time periods. Also, the wireless channels present quality of communication and interruption concerns. 
   Certain specialized formats and standards are presently employed and being refined for wireless data communications. One such format, Wireless Application Protocol (WAP), is being used for wireless communications over the Internet. The WAP protocol exhibits many of the same problems as the other wireless communications, including that only limited amounts of information can reasonably be communicated according to the protocol because of wireless bandwidth limitations. 
   It would be a significant improvement in the art and technology to provide improved wireless packetized data communications, including communications over the Internet and other networks. 
   SUMMARY OF THE INVENTION 
   An embodiment of the invention is a wireless communications network. The wireless communications network includes a wired network, a wireless channel, a wireless application service provider server computer connected to the wired network, a wireless packetized data communications provider equipment connected to the wired network, and a wireless device communicatively connected via the wireless channel to the wireless packetized data communications provider. 
   Another embodiment of the invention is a method of wireless communications. The method includes serving data over a wired network, receiving the data from the wired network, transmitting the data over a wireless channel, and receiving the data over the wireless channel. In other aspects, the method includes transmitting second data over a wireless channel, receiving the second data from the wireless channel, transmitting the second data over the wired network, and receiving the second data over the wired network. 
   Yet another embodiment is a computer readable substrate having a computer program saved thereupon. The computer program includes providing a wireless device with an on-line access to a website, the website maintained on a server computer connected to a wired network, transmitting a packetized data to the wireless device at least in part over a wireless channel, receiving the packetized data by the wireless device, transmitting a second packetized data to the server computer at least in part over a wireless channel, and receiving the second packetized data by the server computer. 
   Another embodiment of the invention is an application service provider for providing network access. The application service provider includes a server computer, a wired network connected to the server computer, a cellular wireless communications system connected to the wired network, and a wireless device communicatively connected to the cellular wireless communications system.

   DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
   Referring to  FIG. 1 , a system  10  serves as a wireless application service provider (ASP). The system  10  includes a network, such as the Internet  12 . The network is operable according to a packetized data protocol, such as transport control protocol/Internet protocol (TCP/IP) or some other network protocol. The network, such as the Internet  12 , interconnects various computing and communications devices, for example, among other devices, a server computer  14  and a wireless ASP server computer  16 . The server computer  14  and the wireless ASP server computer  16  are each one or more server computers including a microprocessor, memory storage, and communications capabilities via wire or wireless connection with the Internet  12 . The server computer  14  and the wireless ASP server computer  16  communicate over the Internet  12  or other network via the protocol of the network. 
   The network, such as the Internet  12 , is also connected with a wireless communications service provider  18 . The wireless communications service provider  18  is, for example, a cellular or other packetized data wireless communications network. The wireless service provider  18  connects by wire connection with the network, such as the Internet  12 . Alternatively, the wireless communications service provider  18  could connect with the network  12  by other communications connection, such as fiber optic, coax cable, wireless channel, or other communications connection. 
   The wireless service provider  18  is capable of communicating through wireless channels with various devices, such as a wireless device  20 . The wireless device  20  is a processing device, such as a data-enabled cellular telephone, a personal digital assistant, a laptop computer, or any of a wide variety of other processing devices that can wirelessly communicate with the wireless service provider  18 . Of course, the wireless device  20  includes communications equipment for accomplishing the wireless communication with the wireless service provider  18 , such as wireless modem. 
   The wireless device  20  communicates through the wireless service provider  18  and over the network, such as the Internet  12 , with the wireless ASP server computer  16 . The wireless ASP server computer  16  serves as a dedicated server for the wireless device  20  in its communications. The wireless ASP server computer  16  sends and receives communications to and from the wireless device  20  over the network, such as the Internet  12 , and on through the wireless service provider  18 . The wireless ASP server computer  16  also communicates over the network, such as the Internet  12 , with other network connected devices, such as the server computer  14 , via protocols in communications channels enabled for such communications on the network. In certain embodiments, for example, the wireless ASP server computer  16  and the wireless device  20  communicate with specialized protocols, such as optimized packetized data protocols, for example, optimized TCP/IP protocols or other protocols such as described in the related patent applications. 
   Referring to  FIG. 2 , a method  20  is performed by the wireless device  20 . The wireless device  20  initially contacts the wireless ASP server computer  16 , for example, over the network, such as the Internet  12 , or is otherwise able to access the wireless ASP server computer  16  or its administrator, in order to obtain a software client for performing appropriate protocols for wireless communications between the wireless device  20  and the wireless ASP server computer  16 . For example, in a step  22 , the wireless device  20  downloads from the wireless ASP server computer  16  a client software that enables operations of the wireless device  20  in communications with the wireless ASP server computer  16  according to the particular protocols. As shown in phantom in  FIG. 1 , the wireless device  20  most likely directly accesses the wireless ASP server computer  16 , such as by wired connection, to download the client software. Alternative means for download of the client software in the step  22  are possible, however, such as storage devices containing the client software can load on or make available the client software to the wireless device  20 , for example, via a floppy disk or other storage mechanism. 
   In a step  24 , after installing the client software at the wireless device  20 , the wireless device  20  communicates via wireless communication with the wireless services provider  18 . The wireless services provider  18  in the step  24  communicates over the network, such as the Internet  12 , to the wireless ASP server computer  16 , the communication from the wireless device  20 . As mentioned, this communication can be performed according to specialized protocols, such as described in the related applications. Alternatively, other protocols can be employed for the initial accessing by the wireless device  20  of the wireless ASP server computer  16  in such manner. 
   Thereafter, in a step  26 , the wireless device  20  communicates with the wireless ASP server computer  16  through the wireless channel between the wireless device  20  and the wireless service provider  18 , and through the network, such as the Internet  12 , between the wireless service provider  18  and the wireless ASP server computer  16 . The communications in the step  26  are made according to protocols of the client software and acceptable for such communications by the wireless device  20  and the wireless ASP server computer  16 . In certain embodiments, the particular protocols for such communications between the wireless device  20  and the wireless ASP server computer  16  are those protocols described in the related applications and maximized for packetized data communications systems. It is to be noted that, although the wireless device  20  and the wireless ASP server computer  16  communicate therebetween via particular protocols, the wireless ASP server computer  16  is capable of communicating with network protocols, such as protocols of the Internet  12 , with other attached devices on the network. For example, the wireless device  20  can communicate a message to the wireless ASP server computer  16  according to the particular specialized protocol. The wireless ASP server computer  16  can then communicate the message to, for example, the server computer  14 , over the network, for example the Internet  12 , via the typical protocols followed by the network, such as TCP/IP in the case of the Internet  12 . 
   Referring to  FIG. 3 , a method  30  is performed by the wireless ASP server computer  16 . In the method  30 , the wireless ASP server computer  16  uploads the client software to the wireless device  20  upon request by the wireless device  20 . Alternatively, the step  32  can be performed in other manner, including by some device other than the wireless ASP server computer  16  or in some other context, such as the administrator of the wireless ASP server computer  16  can deliver a disk containing the client software to the operator of the wireless device  20  for load and installation in typical manner on the wireless device  20 . Of course, all other possible alternatives for achieving the same result are included in the possible embodiments. 
   Thereafter, in a step  34 , the wireless ASP server computer  16  receives an initial communication from the wireless device  20 , which communication has traveled wirelessly to the wireless service provider  18  and then over the network, such as the Internet  12 . The communication from the wireless device  20  initiates communications between the wireless device  20  and the wireless ASP server computer  16 . Those communications between the wireless device  20  and the wireless ASP server computer  16  can, of course, as has been described herein, be made according to the specialized protocols in order to optimize the wireless communications. 
   In a step  36 , the wireless ASP server computer  16  communicates over the network, such as the Internet  12 , with other devices, for example, the server computer  14 . These communications over the network proceed according to typical network protocols. The communications over the network in the step  36  can include communications intended for and received from the wireless device  20 . In effect, the wireless device  20  delivers and receives messages to and from the wireless ASP server computer  16 , and the wireless ASP server computer  16  forwards and receives on behalf of the wireless device  20  those messages over the network to network connected devices. 
   In operation of the system  10  and the methods  20 ,  30 , numerous alternative business and technical arrangements are possible. In certain embodiments, the administrator of the wireless ASP server computer  16  can provide select interfaces and content to the wireless device  20 . For example, the wireless device  20  can be equipped with a form of World Wide Web (WWW) browser that performs according to the specialized protocols for the communications between the wireless device  20  and the wireless ASP server computer  16 . In such instance, the wireless ASP server computer  16  can provide to the wireless device  20  according to those same specialized protocols various data and information, including such things as graphics, images, voice, text, and other digitally represented information and matters. 
   The wireless ASP server computer  16  must also, however, be capable of communicating via typical network protocols with other network connected devices in order to receive and deliver messages from and to those network connected devices, and then transfer those messages on or receive those messages from the wireless device  20 , as appropriate. 
   Although a single wireless device  20 , a single wireless ASP server computer  16 , a single wireless service provider  18 , a single server computer  14 , and a single network, such as the Internet  12 , have been described with regard to the embodiments, it is to be expressly understood that combinations of those elements, such as a plurality of any, certain ones, or all of those elements, is possible in keeping with the scope of the embodiments herein. The network could be an intranet, or even an intranet combination or intranet-extranet combination. Numerous banks of the wireless ASP server computer  16  can be possible for receiving communications from pluralities of wireless devices, and the wireless ASP server computers can be centrally located or distributed through a wide geographic area. In the case of a global network such as the Internet, the network is capable of communicating by its protocols, which may include other specialized protocols for specific situations. The wireless ASP server computer in such instance can communicate with various devices on the network according to those other specialized protocols, if properly equipped as would be known to those skilled in the art. In general, the communications between the wireless device or devices and the wireless ASP server computer or computers occurs according to optimized protocols for wireless communications. These optimized protocols can be implemented entirely in software or alternatively can be hardware, combinations of hardware and software, or other mechanisms. The protocols of the hardware or software, as the case may be, for the wireless communications will, in any event, provide increased communications efficiency, speed, and adaptation for the wireless environment. 
   In the foregoing specification, the invention has been described with reference to specific embodiments. However, one of ordinary skill in the art appreciates that various modifications and changes can be made without departing from the scope of the present invention as set forth in the claims below. Accordingly, the specification and figures are to be regarded in an illustrative rather than a restrictive sense, and all such modifications are intended to be included within the scope of the present invention. 
   Benefits, other advantages, and solutions to problems have been described above with regard to specific embodiments. However, the benefits, advantages, solutions to problems and any element(s) that may cause any benefit, advantage, or solution to occur or become more pronounced are not to be construed as a critical, required, or essential feature or element of any or all the claims. As used herein, the terms “comprises, “comprising,” or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
