## Abstract

A mechanism for providing tuning values to an RF radio module that, does not have memory for storing tuning values. Tuning values are requested from a server maintaining tuning values. The request is made by a device including the RF radio module for which the tuning values are requested. Requested tuning values are then received in accordance with the request. The received tuning values are stored in to a memory of the device including the RF radio module and applied to the RF radio module.

## Claims

### Claim 1

A method comprising:
determining tuning values for a radio frequency (RF) radio module or receiving determined tuning values for the RF radio module;
storing said determined tuning values to an external device;
using an identification code of the RF radio module to request the tuning values for the RF radio module from the external device maintaining tuning values, wherein the request is made by a host device comprising the RF radio module;
receiving said requested tuning values in accordance with said request; and
storing said received requested tuning values to a memory of the host device comprising said RF radio module, and applying said tuning values from the memory of the host device to said RF radio module in operation.

### Claim 2 (depends on 1)

The method according to claim 1, wherein the method further comprises manufacturing said RF radio module.

### Claim 3 (depends on 1)

The method according to claim 1, wherein the determined tuning values of the RF radio module are stored at the external device in association with the identification code for the RF radio module.

### Claim 4 (depends on 1)

The method according to claim 1, wherein said determined tuning values are associated with the RF radio module via the identification code.

### Claim 5 (depends on 1)

The method according to claim 1, wherein the method is executed after the RF radio module is inserted into the host device and before a first use by any end user.

### Claim 6

A radio frequency (RF) radio module, wherein said RF radio module is connectable to a host device comprising an external memory and said RF radio module comprises an interface for accessing said external memory, wherein said RF radio module is configured to receive determining tuning values associated with an identification code of the RF radio module from the memory of the host device before a first use of the host device by any end user.

### Claim 7 (depends on 6)

The RF radio module according to claim 6, wherein said RF radio module does not comprises memory for storing tuning values.

### Claim 8 (depends on 6)

The RF radio module according to claim 6, wherein said radio module comprises one time programmable memory configured to store the identification code.

### Claim 9 (depends on 6)

The RF radio module according to claim 6, wherein said RF radio module is a part of system-in-a-package.

### Claim 10

A host device comprising:
a data communication connection;
a radio frequency (RF) radio module; and
a memory separate from the RF module;
wherein said host device is configured to:
use an identification code of the RF radio module to retrieve, via the data communication connection, tuning values that are determined for the RF radio module from an external device that maintains tuning values;
store in the memory the retrieved tuning values; and
apply the tuning values from the memory to the RF radio module in operation.

### Claim 11 (depends on 10)

The host device according to claim 10, wherein said RF radio module does not comprise memory for storing tuning values.

### Claim 12 (depends on 10)

The host device according to claim 10, wherein said RF radio module is a part of system-in-a-package.

### Claim 13 (depends on 10)

The host device according to claim 10, wherein the host device is further configured to validate tuning values by performing self-testing procedure.

### Claim 14 (depends on 10)

The host device according claim 10, wherein said data communication connection is a serial port.

### Claim 15 (depends on 10)

The host device according claim 10, wherein said data communication connection is a fixed network connection.

### Claim 16 (depends on 10)

The host device according to claim 10, wherein said data communication connection is a wireless connection.

### Claim 17 (depends on 16)

The host device according to claim 16, wherein said wireless connection is said RF radio module using default tuning values.
