Wireless communications apparatus and wireless communications method using the same

A wireless communications apparatus comprising:

• a wireless communications unit configured to communicate with an access point;
• a first controlling unit configured to detect an accessible access point which is accessible through the wireless communications unit, and control access between the detected access point and the wireless communications unit;
• a sensor unit configured to include at least one sensor;
• and
• a second controlling unit configured to receive sensing information from the sensor unit, and determine whether or not a location of the wireless communications apparatus is changed, on the basis of the sensing information,
• wherein when the wireless communications unit accesses the access point, if the second controlling unit determines that the location of the wireless communications apparatus is changed, the first controlling unit re-detects an access point which is accessible through the wireless communications unit.

A wireless communications method using a wireless communications apparatus including a first controlling unit detecting an access point which is accessible through a wireless communications unit and controlling access between the detected access point and the wireless communications unit and a second controlling unit receiving a sensing signal from at least one sensor to determine whether or not a location of the wireless communications apparatus is changed, the wireless communications method comprising:

• detecting, by the first controlling unit, an accessible access point which is accessible through the wireless communications unit around the wireless communications apparatus;
• sensing, by the second controlling unit, a location change of the wireless communications apparatus, if the accessible access point is not detected;
• and
• re-detecting, by the first controlling unit, an access point which is accessible through the wireless communications unit in a changed location of the wireless communications apparatus, if the location change is sensed.
