what is the limitation of wireless communication?

Question

wireless communication

Answer 1

Primary areas of concern in general:

- coverage area
- mobility
- security
- reliability

Wireless technology is just getting to the point where a reasonable number of client access points, with enough bandwidth, may be economically to deploy widely.

The issue with mobility has to do with roaming for the GSM networks to wifi networks, primarily for voice today. This isn't really a technol,ogy issue but a tarrifing issue - the cellular providers will drag their feet on this one as long as they can becasue it ultimately will mean lost revenue for them.

Security is still evolving, but wireless is so easy to access, no physical security involved to speak of, that the security involved becomes very difficult. Difficult in the sense that good security has to be usable, it can't be made so difficult that legitimate end users are looking for ways to bypass it.

Wireless quality is difficult to maintain - the RF space can be a noisy, congested, and varying environment so wireless tends to be less stable than todays wired infrastructure.

Answer 2

Let me tell you, dear Friend, that there are 2 basic drawbacks to modern-day wireless communication.
There are limitations to signal coverage area which doesn't make it as reliable as WiRE communication over longer distances or in some areas. There could be physical obstructions, too.
It is common sense, really.

The other thing about this type of commnication is the level of radiation it produces. This may not be a reason for concern, but it is wotrh it to take into account.

There are also higher prices to pay for your own wireless communication. Companies can afford it in a blink of an eye, but I would personally stick to traditional communication for the near future.
... at least untill prices go down a little more :)

Answer 3

GPRS is an acronym from General Packet Radio Service and it refers to the transfer of information in a mobile network, using a compatible handset. The limitation could be speed, at about maximum 115 KBps, but this depends very much on the network. If you have such a cell phone that supports GPRS you can visit websites like Yahoo, via WAP (wireless application protocol). But GPRS is used also for sending, receiving MMS on your cellphone. To access it, you need an IP, a gateway, username, node and so on... but they should all be provided by your operator.

Answer 4

low power devices,absence of CSMA/CD,freq reuse.SDM is needed.

Answer 5

eliminating static inerference.

Answer 6

low resolution/clarity...
