Station device and method of checking communication performance thereof
A station device includes an output unit that outputs a massage, a communication unit that communicates with a wireless access point which is movable from one place to another place, a determination unit that determines current communication performance with the wireless access point, a storage unit that stores the determined current communication performance, and a controller that compares the current communication performance with pre-stored previous communication performance and controls the output unit to output a message according to a result of the comparison.
1. A method for checking communication performance of a station device, the method comprising:
communicating with a wireless access point which is movable from one place to another place;
determining a current communication performance with the wireless access point;
storing the determined current communication performance;
comparing the current communication performance with a previous communication performance which was previously stored; and
performing an output according to a result of the comparing,
wherein the determining the current communication performance comprises iterating an operation of transmitting a test packet to the wireless access point and receiving the test packet returning from the wireless access point a predetermined number of times, determining a number of packets that are damaged during the iterating the operation, and determining the current communication performance according to the number of damaged packets.
2. The method as claimed in claim 1 , wherein the performing the output according to the result of the comparison comprises:
outputting a first message if the result of the comparing indicates that the current communication performance is better than the previous communication performance; and
outputting a second message if the result of the comparing indicates that the current communication performance is the same as the previous communication performance.
3. The method as claimed in claim 2 , wherein the performing the output according to the result of the comparison comprises not outputting a message if the result of the comparing indicates that the current communication performance is worse than the previous communication performance.
4. The method as claimed in claim 1 , further comprising, by the station device, reducing a size of a packet to be transmitted next if a damaged packet is generated, and increasing the size of the packet to be transmitted next if the transmitting of the test packet is successful.
5. The method as claimed in claim 1 , wherein the station device includes a television that wirelessly communicates with the wireless access point.
6. A method for setting a location of a wireless access point, the method comprising:
fixing a station device in an environment where the wireless access point is to be installed and placing the wireless access point at a predetermined location;
communicating between the wireless access point and the station device; and
retaining or changing the location of the wireless access point by checking a message output from the station device according to a result of comparing current communication performance with previous communication performance,
wherein the communicating between the wireless access point and the station device comprises iterating an operation of transmitting a test packet to the wireless access point and receiving the test packet returning from the wireless access point a predetermined number of times, determining a number of packets that are damaged during the iterating the operation, and determining the current communication performance according to the number of damaged packets.
7. A station device comprising:
an output unit that outputs a message;
a communication unit that communicates with a wireless access point which is movable from one place to another place;
a determination unit that determines current communication performance with the wireless access point;
a storage unit that stores the determined current communication performance; and
a controller that compares the current communication performance with pre-stored previous communication performance and controls the output unit to output a message according to a result of the comparison,
wherein the controller controls the communication unit to iterate an operation of transmitting a test packet to the wireless access point and receiving the test packet returning from the wireless access point a predetermined number of times, and
wherein the determination unit determines a number of packets that are damaged during the iterating of the operation and determines the current communication performance according to the number of damaged packets.
8. The station device as claimed in claim 7 , wherein the controller controls the output unit to output a first message if the result of the comparison indicates that the current communication performance is better than the previous communication performance and output a second message if the result of the comparison indicates that the current communication performance is the same as the previous communication performance.
9. The station device as claimed in claim 8 , wherein the controller does not output a message if the result of the comparison indicates that the current communication performance is worse than the previous communication performance.
10. The station device as claimed in claim 7 , wherein the controller reduces a size of a packet to be transmitted next if a damaged packet is generated, and increases the size of the packet to be transmitted next if the transmitting of the test packet is successful.
11. The station device as claimed in claim 7 , wherein the station device includes a television that wirelessly communicates with the wireless access point.
