Wireless Personal Area Network
A wireless personal area network is used for the interconnectivity of devices that are centered on one space of work and the connections do not need to be connected using wires. This means there must be a wireless technology that allows communication within a suitable distance, or a range that is very short. The two main technologies for this application are blue tooth and wimax. This wireless technology can connect all the usual devices for communication and computing serving purposes that are more specialized especially in hospitals where such communication may be very necessary (Haags& Cummings, 45). One of the key concepts that is applied by wireless technologies is called plug-in and this is a scenario where two wireless networked devices are in close proximity and can communicate as if they are connected using a cable. These devices can thus selectively lock out other devices, which prevent unnecessary interference or unauthorized access to information. WPAN provides seamless operations in homes and businesses where there are computing and communicative systems because they are in the same range of distance with each other.
A Bluetooth PAN is also called the Piconet and has 8 active devices that are placed in a master slave relationship in a parked mode. The first Piconet in the blue tooth is a master while all the other devices are a slave that communicates with the master (Newton, 21). Typically, a Piconet has a range of 1000 m and can be reached under circumstances that are ideal. There are constant innovations in the blue tooth that have allowed the Bluetooth devices greatly to exceed the originally designed distance with hackers even going for half a mile.
WiMAX stands for worldwide interoperability for microwave access and is a technology for telecommunication that provides wireless data transmission using the point to multipoint portable links and mobile internet. This technology can provide up to ten MPS of speed in broadband without having to use cables. It is also called the Broadband, was created to enhance the interoperability of standards, and is normally used to make remote procedure calls and exposition of business methods such as the web services.
Blue tooth and WiMAX differ in their usage. Bluetooth serves as a wireless control of communication between hands free and a mobile phone, which is one of its most popular applications. It is also a network that is used for wireless networking between PCs in a place that is confined and where the bandwidth required is very little. However, the Wimax require a very large band as compared to the Bluetooth. The mouse, the printer, and the key board can use the blue tooth. Apart from being used with the hardware components, blue tooth can be used with the software components in the transfer of files, contact details and with the OBEX devices.
It is a wireless communication between hands free set and a mobile phone and it is one of the most popular applications of the blue tooth. The wireless network can also be used with the GPS receivers, RFID, barcodes, scanners and devices for traffic control. Blue tooth devices have replaced controls that would traditionally use the infrared. It is also used for low bandwidth applications that may not require USB applications and there is a desire for cable free connections (Haag& Cummings, 67). It is also a wireless bridge between the Ethernet networks and for the three seven game consoles and Nintendo’s like Sony play station, 3 and PSP go. Finally, It can be used for dial up access of internet on PCs or the PDA’ using mobile phones that are data enabled to work as wireless modem as Mifi novatel.
The other major difference between Wimax and Bluetooth is the independence of Wimax from other interconnectivities making it a strategic system that can work in a heterogeneous environment. It can also be used with both, relational and non relational database unlike blue tooth which can only be used with relational databases. The other advantage that Wimax has over Bluetooth is that it has call level specifications for interface which provides a neutral method of accessing data while the Bluetooth system is not neutral (Kenneth, 30). Data stored in mainframe databases in a very short range can be accessed through wimax but the Bluetooth will require proprietary computations that must have an SQI access group. This means that wimax can provide faster services than Bluetooth in an office or home environment where a higher level of interoperability is required.
The other advantage is that it provides an access interface for data allowing developers to use an application that can help them to access, view and modify data from a number of different databases at the same time. The Wimax network is faster than the Bluetooth in many other aspects (Kenneth, 34). This is because network transmission can be done using small procedural differences that do not affect the whole unit. This is especially vital for setups that have data relationships that are not very vivid and need to change the relations in order to serve the new requirements of business. The advantage of using wimax in web applications is that it can run in any setup that requires access to a wide range of data. The other advantage is that with a database technology, wimax can encompass all the corporate data to a heterogenic like the Ava DB, which is a supported distribution of the apache derby database that is an open source. Furthermore, the benchmarks are clearly superior to the traditional systems meaning that the Wimax can perform superior tasks. However, Bluetooth can only perform its operations using the navigational rather than the declarative interfaces and the pointers that follow them are not very efficient in continuous transmission of data across networks. Bluetooth can also deflect some of the unfixed system data resulting in loss of data during the process of transmission.
The Bluetooth also lacks the interoperability especially when used SQL tools that have been neglected in the modern computer world but Wimax has such interoperability that helps it to support a wide range of applications in an office and home environment. However, Bluetooth can be used with PCs alongside mobile applications meaning that it is more reliable when transmitting data from a mobile set up to a PC than Wimax. Bluetooth can also construct data structure into sequences that can be stored in files and transmitted along the networks that Wimax cannot support. It can also store data as memory buffers and that data can later be re -awakened in a different computer environment. The resultant data type can be read in different formats that are identical semantically. This means that they can be used for jobs that are more complex that the wimax can hold. This means that the uses of blue tooth are extensive and it can be used in straightforward applications (Mcleod, 87). This transmission of data in a structure that is independent in format ensures that the system does not suffer from the challenges of memory layout or the challenges that arise as a result different communicative techniques. In most of the network transmissions using Bluetooth, there is the use of linear formats that create simplicity in the utilization of interfaces that may be crippled by the use of wimax, which needs applications whose performance is very high and bandwidth that is not easily detectible. On single machines, wimax can prove hard to operate since it is too fragile because of the difference in memory fluctuations. This means that it cannot manage to detect the differences between objects that are being transmitted and the copied ones (Mcleod, 90). Wimax needs a process of differential execution and it is very useful to the office networks especially the ones that have a varying time content, because the graphical data can be easily removed, altered or made to encompass some of the input events without having to use codes that are separate (Newton, 21).
Wimax also deflects the opacity of data type that is abstract by exposing some of the details of implementation that are private. However, the interoperability needs applications to have a capacity to comprehend the formats of serialization of each other. Wimax also has specification of several networks that are server sided meaning that it has a higher ability to enhance the logic of transmission. One advantage of these wimax specifications is that they provide a way that is standard of implementation of the backend code of business, in contrast with the Bluetooth code that is found in applications that are not complex (Mcleod, 92). The code can be used to address problems whose solutions could not have been gotten through the front ended mechanism. It can also be used for transaction processing, control of concurrency and data service messaging. The other usage is naming of directory services and the transmission of the components of software. Finally, it can be used to make remote procedure calls and exposition of business methods such as the web services.
In conclusion, Wimax is a standard mechanism for provision of connectivity that is independent between wide range of databases and the other sources of data that are tabular, including the spreadsheets and the files that are flat. It can encompass all the corporate data to a heterogenic like the Ava DB, which is a supported distribution of the apache derby database that is an open source. This means that wimax can provide faster services than Bluetooth in an office or home environment where a higher level of interoperability is required. The Bluetooth one the other side can selectively lock out other devices, which prevent unnecessary interference or unauthorized access to information. It provides seamless operations in homes and businesses where there are computing and communicative systems because they are in the same range of distance with each other.
