Definition of Mobile Commerce
Any transaction conducted over a mobile telecommunications network.
It represents a subset of all e-commerce transactions both in business-to-consumer and the business-to-business area.

4
Differences between M- and E- commerce
A permanent factor that makes difference between M- and the rest of the E- commerce is the possibility of the user to engage anywhere and anytime in M-commerce transactions; for some this is the crucial difference
The main functional distinction between the E-commerce in general and M-commerce are dynamic Location Based Services (LBS) that use the actual location of the terminal on earth in one way or the other to perform the transaction.

5
Differences between M- and E- commerce (Cont.)
Further difference are the properties of the truly portable terminals: the simple UI facilities, slower processor, and smaller memory resources, as well as tiny energy reserves, as compared to PC:s or Laptops.
A fourth main difference is the relatively small wireless link transmission capacity offered to the terminals; although the capacity is increasing with every network generation (10 kbps, 100 kbps, 1 Mbps..).

Limitations of M-Commerce
Usability problem Usability of a site is critical to attract
attention and retain user stickiness Effectiveness, efficiency, satisfaction Some mobile devices are found to be
ineffective Customers want to find exactly what
they are looking for, easily and quickly, not possible in the 2G text-based environment
More and faster multimedia will be available as 3G spreads
