Expert Solution

Higher data rates within a limited bandwidth higher order modulation as discussed in the previous section providing data rates largeer than the avaliablle bandwidth is fundamentally inefficient in the sence that it requires disproportionally high signal to noise and signal to interface ratios at the receiver.still bandwidth is often a scare and expensive resorce and at least in some mobile and expensive resource and at bleast in some mobile communication scenarious high signal to noise and signal to interfrence ratio can be made available

example: if small cell environment with a low traffic load or for UEs close to the cell site future mobile communication system including the evolution of 3G mobile communication should be designed to be able to take advantage of such scenariors they shold be able to offer very high data rates within a limited bandwidth when the radio condition so allowed

a straightforward means to provide higher data rates within a given transmission bandwidth is the use of higher order modulation implying that the modulation alphabet is extended to include additional signaling alternatives thus allowing for more bits if information to be communicated per modulation symbol

In order to take full advantage of the growing markets of mobile phones in the ASEAN, WingWei Corporation has decided to setup its first manufacturing unit in Malaysia. When officially launched in January 2020, WingWei expects to sell their phones only through their official retail stores. WingWei has estimated to invest RM 50 million in initial investment. This investment includes the market cost of land, basic machineries, and modification cost of the machines. To avoid long-term risk, WingWei has decided...

One of the assumptions made by economists is that firms maximise profits. Using appropriate diagram/s, discuss the long run and the short run profit maximization behaviour in a perfectly competitive market and in a monopoly. In your conclusion you should comment on whether a perfectly competitive market or a monopoly is better for society and why.
