Both Mobile device and the Dongle are
connected to same Access Point
Direct Connection using Hotspot on the
handset
Mobile device hosts an Access Point and the
dongle is the client
Direct Connection using W i-Fi Direct
Mobile device and the dongle form a W I-Fi

3.1 Streaming Mode
This mode uses DLNA (Digital Living Network Alliance) protocol: the Smart Phone (or any other
device on the network) provides DMC, and optionally DMS functionality while the dongle acts as
DMR. The smart phone typically does not transcode the content as long as it conforms to DLNA
codec specification. Note that DLNA discovery and connection works over any IP network. DTCP/IP
can be used for premium content.
Following network topologies can be supported by this mode.

Antenna
PIFA Antenna
Flash memory
Serial NOR Flash: Both 64 Mbit (8 Mbyte) NOR flash and 512 K-bit serial are
supported by the Gemtek WiFi Display firmware. The NOR flash connects to
the CPU via SPI. The CPU can be configured via strapping resistors to read a
boot-loader from SPI NOR flash, then will continue execution by
uncompressing an image from NAND flash.
NAND Flash: A 1Gbit (128 Mbyte) parallel SLC NAND flash stores the Linux
kernel and application code. Also stores the bootloader, and encrypted
DTCP-IP and HDCP 2.1 keys.
DDR3 memory
The 16-bit wide DDR3 interface can run up to 648 MHz for speeds
approaching DDR3-1333. Gemtek WiFi Display features a 2Gb (256 Mbyte)
DDR3 DRAM.

5 Statement
5.1 Federal Communication Commission Interference Statement
This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to
try to correct the interference by one of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which
the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
FCC Caution: Any changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to operate this
equipment.
Operations in the 5.15-5.25GHz band are restricted to indoor usage only.
This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) This device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that
may cause undesired operation.
IMPORTANT NOTE:
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with
minimum distance 20cm between the radiator & your body.
This transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter.
The availability of some specific channels and/or operational frequency bands are
country dependent and are firmware programmed at the factory to match the
intended destination. The firmware setting is not accessible by the end user.
