What do we need to evaluate n-Link technology?

We provide an evaluation platform for evaluation the performance, power and throughput of n-Link module. The evaluation platform has
n-Link evaluation board, (Either RS9110-N-11-02 or RS9110-N-11-03 EVB)
Driver binary
Wi-Fi application provided with the package
x86 Platform with SDIO slot

How much does it cost to get the drivers?

The binary versions of the drivers are free to download. You can use the binary version with the recommended platform. The reference code for the drivers can also license for a fee. You can use the driver reference code to re-compile the driver to your target platform.

Are you modules FCC compliant?

RS9110-N-11-02 is FCC, IC and CE compliant

What do we need to do from an FCC standpoint if we use one of your modules?

The customer can re-use our modular certification as modular certified. This would require the customer to use “Contains FCC ID …” caption on the product. However, this is kind of certification depends on the end customer market regulation. In many markets the complete product is required to undergo FCC certification testing.

What is the power consumption of 02 modules?

We are leaders in ultra low power consumption in the market. We achieve it through 802.11n standard and proprietary algorithms in our internal processor. You can review the power consumption numbers in the datasheet for RS9110-N-11-02. This is a detailed datasheet available upon signing an NDA.

What is the power consumption of 03 modules?

We are leaders in ultra low power consumption in the market. We achieve it through 802.11n standard and proprietary algorithms in our internal processor. You can review the power consumption numbers in the datasheet for RS9110-N-11-03. This is a detailed datasheet available upon signing an ND

What are the different modes of operation for RS9110-N-11-02 module?

The module can operate in 802.11b, 802.11g and 802.11n modes.

What are the different modes of operation for RS9110-N-11-03 module?

The module can operate in 802.11a, 802.11b, 802.11g and 802.11n modes.

What are the different modes of operation for RS9110-N-11-04 module?

The module can operate in 802.11b, 802.11g and 802.11n modes

Does nLink have ad-hoc functionality?

Yes, n-Link modules RS9110-N-11-02 and RS9110-N-11-03 modules can operate in ad-hoc mode using the existing client driver software.

Is a demo of ad-hoc functionality available?

Yes, the demo and complete functionality is available. You can test the functionality on the evaluation board of the client.

How to configure the module to create an Ad-Hoc network?

Please refer to the application note available here for creating the ad-hoc mode network creation.

How many nodes are supported in Ad-Hoc network?

We support up-to 32 clients in an Ad-Hoc network.

Is security enabled in Ad-Hoc mode?

Yes, WPA, WPA2 and PSK security can be enabled in Ad-Hoc mode.

What are all the configuration commands that are supported?

We support iwconfig utility to configure the n-Link driver. You can refer to iwconfig user guide for complete list of commands.
The complete list of configurable commands is present in Driver porting guide document. Please refer to that.

Is wireless configuration possible?

Yes, you can use iwconfig and iwpriv utility on Linux to configure wireless parameters. On WinCE you can use Windows Zero Configuration utility (WZC) for configuring the wireless parameters.

What does the LED indicate on evaluation board?
