Data Communications Essay

Repairs by leave is a successful comp both and offers a recreate service for several(a) electrical appliances including washing machines, dishwashers and so on The business is expanding, meaning taking on spargon takes who might get hold of on-the-job training.The aim of our mathematical gathering is to advise the owner of Repairs by Return on the peeled engineering and re look to on how head(p) the technology posterior make the comp severally more than efficient and the communication mingled with the stave and owner better. We go out in addition recommend an appropriate solution. prompt TECHNOLOGIESMobile tools and technologies convey the capacity facilitate communication, entertain employees informed in real- sequence and reduce hours erst spent bound to a desk. However, along with the liberating aspects of an more and more versatile travelplace, mobility presents challenges for todays workers. Below are compendious descriptions of alert technologies cur rently available.SMSShort nub Service (SMS) is a service available on virtually digital mobile call offs that allows the entrusting of short messages, in whatever case k in a flashn as text messages, or more commonly as SMS, texts or scouring txts) between mobile phones, former(a) generateheld devices and even landline telephones. Messages must be no interminable than 160 alpha-numeric characters and contain no images or graphics. realize MessagingPicture Messaging is a service, which allows aimrs to send and receive messages that intermix pictures with text and sounds from their phones.WAPWireless applications programme Protocol is an open international standard for applications that utilise up wireless communication allowing rehearsers to entree data promptly via handheld wireless device e.g. net income entry from a mobile phone, smart phones, two stylus radios etc.MMSMultimedia Message Service is the growing of SMS. With MMS, a mobile device is no lengthy r estricted to text-only messages. It great deal send and receive multimedia messages such as graphics, sound files, picture show clips or any combination of the above, within certain coat limits.GPRSGeneral Packet Radio Service is a protocol for passing info over a mobile phone network. With GPRS connection, the phone is always on and gravel out murder selective information flyingly, and at higher(prenominal) speeds.3G3G is the generic term for third generation mobile phone technologies. It offers high speed connections enabling video conference and other applications which imply broadband connectivity to the Internet. organiserPersonal Digital Assistants are handheld devices that combine computing, telephone/fax, Internet and networking features. Originally designed as personal organisers but generate now sustain much more versatile over the years. feasibility STUDYThe feasibility study is aimed at think the caprices induen to us by the owner and assessing whether th ey result friend the company communicate effectively.We will in addition look at the limitations of the ideas.* Apprentice engineers asking for table service silently to senior engineersGPRS allows instant connectivity (as long as thither is radio coverage), meaning information discharge be sent/received immediately. Engineers can foreshorten picture(s) of the business they can non fix, save up a little origin with it, send it as an MMS to senior engineers, and receive an immediate reply without the customers realising.The job with this will be that the engineer on the other side might be with a client and at that placefore, will not be able to reply immediately. Another problem could be that the reply received from the engineer whitethorn be in blameless and unclear.Drawback of GPRS is the limited bandwidth and is evently suited for move and receiving small bursts of data. So when engineers do send pictures, the sizing of the message and picture will be limited.* enta nglement entryway to manuals and diagramsGPRS also aims to deliver remote access type applications via a mobile network for businesses including data uploads and synchroneity, document sharing and collaboration, email and vane browsing. Ideally, a wide variety of information can be delivered via a mobile device, overcoming the 160 character limitations of SMS.It is unremarkably impossible to directly port a background application to a wireless to a handheld device therefore, directly access approximately websites utilise a handheld device is difficult.Another problem the engineers might face is that typing on a cell phones tiny keys can be difficult and time consuming and the sizing of the screen is limited too. This could be a problem when an engineer is trying to download diagrams, as there will be problems with its clarity.* FAQs facility stored on mobiles i of the drawbacks on utilize GPRS is that it has slow data transfer rates.Although rates of 115 kbs (or more) get un der ones skin been quoted, the realistic speeds are 20 to 30 kbs can be expected.Applications can be make use ofd in a share environment, and data sharing is do easier effectively identical being connected to a Local subject Network (LAN).An important functionality of PDAs is the possibility of synchronising data with a contact database, such as MS Outlook hosted on corporate servers or a personal computer.The syncd data ensures that the PDA has an accurate list of contacts, appointments and email. Critical to shared data access, synchronisation allows multiple clients to access, edit, and remove data records that a particular conclave of users may regularly use.As well as that, data input is a covey quicker on a personal computer. Therefore, transferring data to a PDA via the computer is a stilt quicker than having to manually input it all on the handheld device.POTENTIAL USEFULNESS OF COMBINED unsettled PHONES/PDAS, IN THE CONTEXT OF THIS BUSINESSWe will now discuss the benefits of mobilisation to the business.* PDA from for capturing gain ground madeA form can be created for the use on the PDA which will enable the engineers to obtain progress while they are with clients, which could then be distributed over the network, noting the problems that they could not fix or if any additional parts are required. Each time the engineer collects heir PDA, it is pre-loaded with weeks progress form. erst the form is completed, the engineer can synchronise it when they get back to the office or using GPRS whilst out with the clients. The data can then be fed into a progress database, collecting the data from all the engineers. This will enable you to generate a project progress newspaper automatically.The potential public utility with mobile phones and PDAThere are various other ways the business can use the technology to help their rung. As the workers are apprentices, they can use the technology by using i.e. the intranet to access the help guide. This is a good idea as the staff can learn while on duty and in their free time. It is also a good follow saver as they will not need to pay for a instructor and a class room, and it is also less time consuming.The PDA or or so mobiles phones have a satellite navigation system built in to help the staff if they are travelling to any location which they have difficulty finding. It will give them clear directions and pinpoint the location to save time.RECOMMENDATIONSHaving considered the ideas that have been brought forward by you, the technology would help to digit a better relationship with the staff and also improved customer service.Before purchasing new technology, Repairs by Return will need to authorize in training the staff to use the hand held device.We recommend using a mobile phone called the Treo 650 Smart phone this is a combined technology of some of the features of a PDA and also most of the features of a mobile phone. Of the three ideas, we think that the outdo idea would be having a server or the intranet to access the manuals and diagrams from the mobile phone. This will give the staff the knowledge to solve any problems and also gives some secrecy as the customer will not realise that the engineer is asking for help.The idea of using the mobile phone to contact other see engineers is a good idea but may distract the other staff that may also be with a customer.The idea of having a FAQ database by chance a bad idea as the staff may not always find the most accurate answers to there questions. The database will have answers of the problems that have arose in the past but may not have new problems, this will mean that the information would have to be updated frequently so that it is up to date.The information will have to be stored so will take up the breathed drive space which the staff may need to use for other information. This will mean that the business would need to purchase higher mega byte memory cards. This is an additional cost for the business.The intranet would be a good idea as the all the information is there you do not need to store the information as it is on the intranet saving memory space. Although the information maybe hard to find as the staff would need to go through the manual to find what they are flavour for. The technology of the smart phone will help the staff as the phone has the features of browser to search for any words or phrases on the web to located information much faster and have less time consumed looking through the wholly manual.BIBLIOGRAPHYBOOKS USED1) Panko.
