2. What is mobile computing
Mobile Computing is a technology that allows transmission of data, voice and video via a computer or any other wireless enabled device without having to be connected to a fixed physical link. The main concept involves −
Mobile communication
Mobile hardware
Mobile software

3. Mobile Communication
The mobile communication in this case, refers to the infrastructure put in place to ensure that seamless and reliable communication goes on. These would include devices such as protocols, services, bandwidth, and portals necessary to facilitate and support the stated services. The data format is also defined at this stage. This ensures that there is no collision with other existing systems which offer the same service. Since the media is unguided/unbounded, the overlaying infrastructure is basically radio wave- oriented. That is, the signals are carried over the air to intended devices that are capable of receiving and sending similar kinds of signals.

4. Mobile hardware
Mobile hardware includes mobile devices or device components that receive or access the service of mobility. They would range from portable laptops, smartphones, tablet Pc's, Personal Digital Assistants. These devices will have a receptor medium that is capable of sensing and receiving signals. These devices are configured to operate in full- duplex, whereby they are capable of sending and receiving signals at the same time. They don't have to wait until one device has finished communicating for the other device to initiate communications.
Above mentioned devices use an existing and established network to operate on. In most cases, it would be a wireless network.

5. Mobile software
Mobile software is the actual program that runs on the mobile hardware. It deals with the characteristics and requirements of mobile applications. This is the engine of the mobile device. In other terms, it is the operating system of the appliance. It's the essential component that operates the mobile device. Since portability is the main factor, this type of computing ensures that users are not tied or pinned to a single physical location, but are able to operate from anywhere. It incorporates all aspects of wireless communications.

6. Examples of mobile Computing
Smartphones/cell phones · Laptops · Tablets · Carputers · Bluetooth devices · E-book readers · Handheld game consoles · Cameras

7. What is wireless
Wireless is a term used to describe telecommunications in which electromagnetic waves (rather than some form of wire) carry the signal over part or all of the communication path. Some monitoring devices, such as intrusion alarms, employ acoustic waves at frequencies above the range of human hearing; these are also sometimes classified as wireless, fax, data communication, and the effective use of a larger portion of the spectrum, the term "wireless" has been resurrected.

8. Common examples of wireless equipment in use today include:
Cellular phones and pager
Global Positioning System (GPS)
Cordless computer peripherals
Cordless telephone sets
Home-entertainment-system control boxes Remote garage-door openers
Two-way radios
Baby monitors
Satellite television
Wireless LANs or local area networks

9. Wireless technology is rapidly evolving, and is playing an increasing role in the lives of people throughout the world. In addition, ever-larger numbers of people are relying on the technology directly or indirectly. (It has been suggested that wireless is overused in some situations, creating a social nuisance.) More specialized and exotic examples of wireless communications and control include:
Global System for Mobile Communication (GSM)
General Packet Radio Service (GPRS
Enhanced Data GSM Environment (EDGE)
Universal Mobile Telecommunications System (UMTS)
Wireless Application Protocol (WAP)
i-Mode 

10. Wireless can be divided into:
Fixed wireless -- the operation of wireless devices or systems in homes and offices, and in particular, equipment connected to the Internet via specialized modems
Mobile wireless -- the use of wireless devices or systems aboard motorized, moving vehicles; examples include the automotive cell phone and PCS (personal communications services)
Portable wireless -- the operation of autonomous, battery-powered wireless devices or systems outside the office, home, or vehicle; examples include handheld cell phones and PCS units
IR wireless -- the use of devices that convey data via IR (infrared) radiation; employed in certain limited-range communications and control systems

11. PROs and CONS MOBILE COMPUTING PROS
Being productive during down time. Obviously, being able to work virtually anywhere is the best benefit of the mobile computing. There are times when you want to do some work when you have some down time, like when you’re waiting for your flight, waiting for someone in a restaurant, and other waiting activities.
Being able to work when you least expect it. There are times when you suddenly need to do some report, respond to an important , or send a file asap. During these times, it’s reassuring to know that you can just power on your mobile device and start working! Globalization has made working with co-workers from other countries and different timezones a necessity. As a result, your working hours is oftentimes disregarded by your foreign counterparts.
Being able to play my multimedia collection anywhere. All work and no play can may you a dull person.

12. CONS
Rest time is no longer rest time. Although we can do some tasks on our computers during our rest time or down time, it also takes away actual time for rest. Our minds and bodies need time to calm down and recharge, too.
Work-Life Imbalance can happen. This is another sad consequence of mobile computing. Because we can do our work anywhere, we tend to work at home. When we do work from home, or when we bring home our work, we eat up time we can spend for our family, or for personal time. This imbalance often results in workaholism.
We become connected 24/7. As cool as it may sound, being connected 24/7 is not healthy. Being connected all the time can keep you up all night resulting in lack of sleep. Lack of sleep has been proven to cause a lot of sickness. Another ill effect of being connected 24/7 is the one mentioned in the previous bullet point: work-life imbalance.

13. Wireless
PROS
Mobility – user device can be moved easily within the wireless range
Neat and easy Installation – since no cable running here and there, just start up the wireless device and you’re ready to rumble
Less cost for cabling infrastructure and device
More user supported – cable device have limited slots whereas wireless does not.

14. CONS
Relatively lower bandwidth speed – example: although currently /n could reach 128 Mbps, UTP cable can reach 1 Gbps. And more user mean each bandwidth get smaller. That is why currently wired backbone network is still preferred.
Ease of access means more security also necessary to protect data and/or bandwidth, since people can connect anywhere within range without seeking network plug.

15. What is the difference between mobile and wireless?
Mobile is a word that is commonly used to describe portable devices. A mobile device is one that is made to be taken anywhere. Therefore, it needs an internal battery for power, and must be connected to a modern mobile network that can help it to send and receive data without attaching to a hardware infrastructure.

16. Wireless, on the other hand, does not mean mobile
Wireless, on the other hand, does not mean mobile. Traditional computers or other non-mobile devices can access wireless networks. One very common example is the use of a localized browser product in a local area network (LAN), where the router takes what used to be a cabled interaction and makes it wireless. Other kinds of wireless networks called wide area networks (WAN) can even use components of 3Gor 4G wireless systems made specifically for mobile devices, but that doesn’t mean that the devices on these networks are mobile. They may still be plugged in or require proximity to a router or network node.

18. Future of Wireless

19. CONCLUSION
In conclusion, wireless communications globally is something that people can expect as technology advances. Wireless communications has a lot of benefits and can make the world a lot more efficient. It does have concerns though as with every other new advancement that is made in today’s world.
The issues with security regarding access to a person’s personal information or the negative impact that it may seem to have on society are a few things that are holding back the progress that wireless technology could be making.
On the other hand, in mobile computing people can work from the comfort of any location they wish to as long as there is a connection.
