Tma 02


Question 1

(a) '2b: In cases where a calculation is required, it is often useful to
include the actual data and the formula used in order to gain the
result.  In this case you would use: 31x1800/100=558.  By doing this
you ensure that, even if you have made some mistakes in the answer, you
will gain some marks for the process involved.'

'Please use a spell checking system in order to improve the quality of
your written document (see my notes in the inline comments).'

(b) The first comment helped with question 3 (b) (ii) in TMA02; it helped me to show,   whether right or wrong, that I can gain marks for showing the calculation using the correct units.

The second comment helped me to understand how important it it to do a word count and a spell check to keep the text concise and clear; e.g. when writing a summary, as in question
3 (a).

Question 3

What's the big deal about WiMax

Margaret reardon (3 october 2008)

A brief summary

(a) WiMax (Worldwide Interoperability for Microwave Access) is an IP-based technology which can be used in fixed, mobile, or portable devices.
It's main purpose is to offer wireless broadband and   It supports high data rates, which allows users a little more speed.

This particular technology can be used to connect to the internet while on the move, through digital cameras and smartphones for example.
It is claimed that WiMax can deliver 40mbps through each channel, split among many businesses, residences and mobile phone users.

Wi-Fi and WiMax are both IP-based wireless technologies, Wi-Fi catering more for indoor connection over shorter ranges, used for home networks and libraries etc.

One technology used is HSDPA (High Speed Data Package Access) which offers speeds upto 3.6 mbps, though in reality, something more like about a fifth of that; and the more users there are on a network the less capacity is available for users.   also, the further a signal travels...
