KONA MOBILITY is exclusively providing DM solution fulfilling OMA international standards among various DM technologies to global mobile phone manufacturers, and major telecommunication business holders in all over the world make it obligated to equip OMA DM in mobile devices such as smart phone.
OMA (Open Mobile Alliance)
OMA is an industrial forum for the development of telecommunication service and is comprised of telecommunication business holders (Telco), device manufacturers, and network manufacturers in all over the world. The purpose of operation is to enact and distribute open technology specifications for the compatibility among devices, areas, service providers, operators, and networks, and major fields enacted with specifications include DM (Device Management), LBS, IoT, and APIs.
Go to OMA websiteDM (Device Management)
For OMA DM, telecommunication business holders or device manufacturers enact specifications for users to efficiently setup and use devices with explosively increasing amount of functions for mobile devices and applied services. DM technology is contributing to create indirect profit and reinforce brand competitiveness by saving operating costs, efficiently managing the product, and providing user convenience such as A/S or recall. At the same time, major telecommunication business holders in North America, Europe, Japan, and Korea make it obligated to equip OMA DM on devices that use their own telecommunication network.
LwM2M (Light Weight M2M)
OMA LwM2M was developed to overcome low-end device and bandwidth limitations of existing DM protocols such as OMA DM, TR-069, SNMP, and more within IoT environment LwM2M is developed based on CoAP and UDP to enable IoT device management, firmware updates, positioning, remote control, and device security.
While OMA DM is suitable for smartphone, mobile modem, and connected car, OMA LwM2M is suitable for constrained devices such as IoT devices.

| Communication Model |
More Complex
(Package 0-4) |
Registeration followed by simple CoAp
(GET,PUT,POST,DELETE) |
| Data Model | DM Tree for Management object | Flat, Simple, Object with URI |
| Message Overhead | HTTP+XML (or WBXML) Message | CoAP + binary encoded TLV or JSOn |
| Device Applicability | Mainly Mobile device | Constrained local wireless or M2M cellular based devices |
FOTA Firmware Over The Air
Firmware over-the-air technology empowers firmware/software updates of the device by resolving issues with low-bandwidth and high packet costs of mobile services Rather than downloading whole firmware/software packet, only the smallest delta files are generated from the new version and the original version of the firmware/software for an update.
FOTA technology is most widely used for updating F/W binary file, high-volumed map file, audio files for smart phones, Connected Car, and AVN (Audio Video Navigation) Size of the delta file generated between two version can be reduced up to 0 01% of the original version which reduces cost of mobile data usage and time it takes to update.
* Over The Air With Delta Technology
Generating the smallest delta between two versions of the firmware/software leads to lighter and faster update Licensed with one of the original patent holder for delta generation, SmithMicro, KONA MOBILITY became very first local company to provide patent-issue free FOTA solutions to customers in Korea
