ucchip is a fast-growing chip design company, which provides fast customization of low-cost, low power iot SoC chips and iot solutions for all industries.
We can provide variety kinds of chips such as GPRS/GPS, Wiota, LTE
This project is terminal side wiota protocol and running on UC8288 chip.
UC8288 series chips are equipped with the wide area Internet of Things communication protocol WloTa, which is designed on the development platform with UCCHIP's own intellectual property rights. It is fully integrated and has advantages in cost, power consumption, performance, security and other aspects. It is highly customizable and flexibly supports different industry application scenarios.

WloTa (Wide-range Intetnet Of Things communicAtion Protocol) protocol designed for the wide-area wireless loT communication is chinese independent intellectual property rights completely.
The core characters include large coverage, low power consumption, a large number of connections, low cost, working at 230 MHZ to 470 MHZ in sub 1G spectrum.
So it is flexible and can meet the demand of Internet communication for many industries.
WIoTa protocol design fully consider the diversified characteristics of IOT, adopting flexible architecture for adapting to various application requirements.
According to the network size, multiple functional entity can be combined into a hardware entities.
★ Synchronous mode
AP network by star, point to multipoint. the system is high efficiency and has large capacity, can provide precise timing for IOT
terminal, suitable for the special frequency band such as 230 MHZ. It support hierarchical network to enlarge the network coverage.
★ Asynchronous mode
Point to point, point to multipoint. The implementation in this mode is simple for these is no need to plan network.
but the capacity is low than synchronous mode.
WloTa communication protocol has also taken measures to optimize the design of the control signal and design conflict
adjustable mechanism to maximize capacity in asynchronous mode .
★ MESH mode
This is no center mode. In asynchronous mode, the support of no center radio between IOT terminals is ebable.
