MOBILE COMPUTING Vs WIRELESS
"mobile" and "wireless" are often used interchangeably but
in reality, they are two very different concepts applied to modern computing
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.
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 3G or 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.
and wireless systems really accomplish two very different things. While a
wireless system provides a fixed or portable endpoint with access to a
distributed network, a mobile system offers all of the resources of that
distributed network to something that can go anywhere, barring any issues with
local reception or technical area coverage.
another example of the difference between mobile and wireless, think of
businesses that offer Wi-Fi hotspots. A Wi-Fi hotspot is typically a resource
for someone who has a relatively fixed device, such as a laptop computer that
doesn‘t have its own internal Internet access built in. By contrast, mobile
devices already have inherent access to the Internet or other wireless systems
through those cell tower networks that ISPs and telecom companies built
specifically for them. So mobile devices don‘t need Wi-Fi - they already have
who are used to using both wireless and mobile networks, this distinction may
seem very simple. However, the difference between providing mobile and wireless
is likely to be something that gets explored more as new technologies continue
to develop, and companies continue to offer more different kinds of interfaces
subgroup from wireless. We have wireless systems that are not mobile and we
have technologies which are wireless but not mobile in sense of technologies
deployed in mobile operators networks. We have fixed wireless (e.g. fixed
WiMAX) and e.g. TETRA which is not technology deployed in mobile (operators)
communication engineering, wireless communication(both static and dynamic) is
communication between Nodes/system without use of direct physical connection
rather it is through a non conducting or dielectric media. Where as in mobile
communication, communicating nodes moves within specified area and method of communication
is wireless communication suitably..e.g.-Mobile Ad-hoc networks (MANETs).
Communication in itself is a very broad concept that is achieved using various
inter-related technologies. Mobile Communication utilizes some of the
technologies that are made available / possible by Wireless Communication. Some
of the popular wireless technologies employed in Mobile Communication include:
GPRS (General Packet Radio Service), LTE (Long Term Evolution), HSPA (High
Speed Packet Access), GSM (Global System for Mobile Communication), EDGE
(Enhanced Data GSM Environment), CDMA (Code Division Multiple Access) and its
refers to the method of transferring information between a computing device,
such as a personal data assistant (PDA), and a data source, such as an agency
database server, without a physical connection. However, not all wireless
communications technologies are created equally, offer the same uses or are
computing refers to computing devices that are not restricted to a desktop. A
mobile device may be a PDA, a smart phone or a web phone, a laptop computer, or
any one of numerous other devices that allow the user to complete tasks without
being tethered, or connected, to a network. Mobile computing does not
necessarily require wireless communication. In fact, it may not require
communication between devices at all.
communication is simply data communication without the use of a landline. This
may involve a cellular telephone, a two way radio, a fixed wireless connection,
a laser, or satellite communications. Here the computing device is continuously
connected to the base network.
computing essentially refers to a device that is not always connected to a
central network. This group of devices includes laptops, newly created smart
phones and also PDA's. These products may communicate with a base location,
with or without, a wireless connection
