What is 'Mobile Commerce' or m-commerce

Mobile commerce transactions continues to grow, and the term includes the purchase and sale of a wide range of goods and services, online banking, bill payment, information delivery and so on.

Mobile was a portable communication device which we could use to connect, make a call, receive call or sms to other person who live not near by.2000s-era mobile phones support a variety of other services, such as text messaging, MMS, email, Internet access, short-range wireless communications (infrared, Bluetooth), business applications, gaming, and digital photography. Mobile phones which offer these and more general computing capabilities are referred to as smartphones.

Smart Phones

Smartphones have a number of distinguishing features. The International Telecommunication Union measures those with Internet connection, which it calls Active Mobile-Broadband subscriptions (which includes tablets, etc.). In the developed world, smartphones have now overtaken the usage of earlier mobile systems. However, in the developing world, they account for only 20% of mobile telephony.

E-Commerce 

Commerce normally refers to the macroeconomic purchase and sale of goods and services by large organizations at scale. Properly managed, commercial activity can quickly enhance the standard of living in a nation and increase its standing in the world. However, when commerce is allowed to run unregulated, large businesses can become too powerful and impose negative externalities on citizens for the benefit of the business owners.

E-commerce describes any business or commercial transaction that includes the transfer of financial information over the Internet. E-commerce, unlike traditional commerce between two agents, allows individual consumers to exchange value for goods and services with little to no barriers.

E-commerce has changed the ways in which economies conduct commerce.

In the past, imports and exports conducted by a nation posed many logistical hurdles, both on the part of the buyer and the seller. This created an environment where only larger companies with scale could benefit from export customers. Now, with he rise of the Internet and e-commerce, small business owners now have a chance to market to international customers and fulfill international orders.

Companies of all shapes and sizes can engage in international commerce. 

Export management companies help domestic small businesses with the logistics of selling internationally. Export trading companies help small businesses by identifying international buyers and sourcing domestic companies that can fulfill the demand. Import/export merchants purchase goods directly from a domestic or foreign manufacturer, and then they package the goods and resell them on their own as an individual entity, assuming the risk but taking higher profits.

According to Investopedia 
Mobile commerce is the use of wireless handheld devices such as cellular phones and laptops to conduct commercial transactions online. 
 "the delivery of electronic commerce capabilities directly into the consumer’s hand, anywhere, via wireless technology."
-Global Mobile Commerce Forum

Many choose to think of Mobile Commerce as meaning "a retail outlet in your customer’s pocket."

Future in m-commerce 

5G is a technology and term used in research papers and projects to denote the next major phase in mobile telecommunication standards beyond the 4G/IMT-Advanced standards. The term 5G is not officially used in any specification or official document yet made public by telecommunication companies or standardization bodies such as 3GPP, WiMAX Forum or ITU-R. New standards beyond 4G are currently being developed by standardization bodies, but they are at this time seen as under the 4G umbrella, not for a new mobile generation. Deloitte is predicting a collapse in wireless performance to come as soon as 2016, as more devices using more and more services compete for limited bandwidth for their operation.
