Apparatus and method for providing network configurability in a wireless network

1. A node configured to operate in a wireless network, comprising:

scanning circuitry to perform a scanning process to detect one or more upstream nodes of said wireless network, wherein an existing connection to an upstream node is broken as a consequence of said scanning process;

connection circuitry to form a connection to at least one of said one or more upstream nodes in response to said scanning circuitry completing said scanning process;

storage circuitry to store one or more triggers; and

processing circuitry to cause said scanning circuitry to perform said scanning process in response to at least one of said one or more triggers, wherein

said scanning circuitry is restricted to performing said scanning process within one or more allowed times; and

said one or more allowed times include at least one of:

a time when usage of said node is at or below 25% of its average maximum usage for a given day, and

a time when usage of said node is at a lowest point.

2. A node according to claim 1 , wherein said one or more triggers specify a condition comprising expiration of a timer.

3. A node according to claim 1 , wherein

said node comprises ranking circuitry to rank said one or more upstream nodes based on a set of criteria;

said connection circuitry is configured to form a connection to a highest ranked upstream node; and

said one or more triggers specify a condition comprising failing to connect to said highest ranked upstream node.

4. A node according to claim 3 , wherein said set of criteria includes radio frequency properties.

5. A node according to claim 3 , wherein

said set of criteria includes a preferred upstream node; and

said one or more triggers specify a condition comprising failing to connect to said preferred upstream node.

6. A node according to claim 1 , wherein said node is stationary.

7. A node according to claim 1 , wherein

said node comprises an antenna array; and

said scanning process causes said antenna array to sweep an area over a period of time.

8. A node according to claim 7 , wherein said antenna array sweeps over said area over a period of time by rotation of said antenna array.

9. A node according to claim 7 , wherein said antenna array sweeps over said area over a period of time by altering a shape of a beam of said antenna array.

10. A node according to claim 1 , wherein said scanning process causes upstream nodes of said wireless network to be discovered by scanning a plurality of frequency bands.

11. A node according to claim 10 , wherein

said node comprises an antenna array; and

said scanning process causes said antenna array to sweep an area over a period of time for each band in said plurality of frequency bands.

12. A node according to claim 1 , wherein

said one or more upstream nodes provide a wireless backhaul; and

said node acts as a relay node connectable to one or more items of user equipment to which access to said wireless backhaul is provided.

13. A method comprising:

performing a scanning process to detect one or more upstream nodes of a wireless network, wherein any existing connection to an upstream node is broken as a consequence of said scanning process;

forming a connection to at least one of said one or more upstream nodes in response to completion of said scanning process;

storing one or more triggers; and

performing said scanning process in response to at least one of said one or more triggers, wherein

said scanning process is restricted to being performed within one or more allowed times; and

said one or more allowed times include at least one of:

a time when usage of said node is at or below 25% of its average maximum usage for a given day, and

a time when usage of said node is at a lowest point.

14. A node configured to operate in a wireless network, comprising:

means for performing a scanning process to detect one or more upstream nodes of a wireless network, wherein any existing connection to an upstream node is broken as a consequence of said scanning process;

means for forming a connection to at least one of said one or more upstream nodes in response to said means for performing said scanning process completing said scanning process;

means for storing one or more triggers; and

means for causing said means for performing a scanning process to perform said scanning process in response to at least one of said one or more triggers, wherein

said means for performing a scanning process are restricted to performing said scanning process within one or more allowed times; and

said one or more allowed times include at least one of:

a time when usage of said node is at or below 25% of its average maximum usage for a given day, and

a time when usage of said node is at a lowest point.
