Survey of Wireless Computing


Wireless technology can provide many benefits to computing including faster response to queries,

reduced time spent on paperwork, increased online time for users, just-in-time and real time control,

tighter communications between clients and hosts. Wireless Computing is governed by two general

forces: Technology, which provides a set of basic building blocks and User Applications, which

determine a set of operations that must be carried out efficiently on demand. This paper summarizes

technological changes that are underway and describes their impact on wireless computing development

and implementation. It also describes the applications that influence the development and

implementation of wireless computing and shows what current systems offer.

1 Introduction

Wireless computing is the topic of much conversation today. The concept has been around for some

time now but has been mainly utilizing communication protocols that exist for voice based

communication. It is not intended to replace wired data communication but instead to be utilized in

areas that it would be otherwise impossible to communicate using wires. Only recently has the industry

been taking steps to formulate a standard that is more suitable to data transmission. Some the problems

to be overcome are:

(1) Data Integrity - relatively error free transmission,

(2) Speed - as close as possible to the speed of current wired networks,

(3) Protection - making sure that the data now airborne is encoded and cannot be tapped by

unwelcome receivers,

(4) Compatibility - ensuring that the many protocols that sure to be created subscribe to a standard

to allow inter-operability,

(5) Environmentally safe - strengths of electromagnetic radiation must be kept within normal levels.

In our study of the theories and implementation concerns of wireless computing, we found that it is

being treated in an object oriented fashion. Scientists and development crews, including the IEEE, are

doing their best to implement wireless connectivity without changing the existing computer hardware.

As a result, a lot of focus is on using existing computer hardware and software to convert data to a

format compatible with the new hardware which will be added to the computer using ports or PCMCIA

connections that already exist. This means that wireless communication will be transparent to the user

if and when wireless computing is utilized on a wide scale.

Wireless computing applications covers three broad areas of computing today. Replacement of normal

wired LAN's need to retain the speed and reliability found in wired LAN's. Creation of semipermanent

LAN's for quick and easy setup without the need for running wires. This would be necessary for events

such as earthquakes. The last category is that of mobile computing.
