GoodWAN LPWAN technology

The LPWAN technology developed by GoodWAN company provides transfer of short, rare, significant messages from the economic independent sensors located at long distances from each other. It is created for tasks in which LTE-M and the existing LPWAN of network are inefficient.

�� Concentration on specific optimal mass cases, but not on universality - as LoRaWAN or specialization on housing and public utilities (the Martin, Vaviot).
�� Use of the (20 years +) and world experience for development of optimal LPWAN of the technology which is most adapted for for service of the most mass, applications not available earlier.

Main characteristics of radio of a path for license-free LPWAN of technologies

• Work range in forward channel: up to 50 km in direct visibility, 10 km in rural areas, 3 km within dense urban development.
• Small consumption of the transmitter, long term of service of the battery.
• Work, generally in the license-free frequency range of 433 MHz, 868 MHz, or 2.4 GHz with a power of 10-100 MW and, most often, a limited operating cycle of 0.1% or 1%.
• Low physical information transmission rate (increase in speed leads to reduction of a range of a system).
• High receiver sensitivity – 138 dBm and more.
• The small volume of the transferred messages – in several byte or tens of bytes.
• A small amount of the transferred messages in day.
• Existence of a reverse channel is preferable.
• Enciphering of messages

Features of GoodWAN technologies

• The main feature and main advantage of GoodWAN is with big capacity and high noise immunity forward channel (as at SigFox) and, at the same time, symmetric on the range simple in implementations and a cheap reverse channel (as at LoRa).
• For transfer in forward channel UNB of a signal with frequency, but not phase shift keying as it is implemented at SigFox that considerably improves transmission quality of information from moving objects is used.
• Digital processing of a signal in the Base station is implemented on the specialized signal processor that made cost value of BS below competitors, without deterioration in its characteristics, increased resistance to "hangups" of a system and lowered its energy consumption.
• GoodWAN proposes solution of the problem of roaming of moving objects in network of a set spatially of the distributed Base stations which has no qualitative solution at SigFox (the Martin, Vaviot), the vprotokol LoRaWAN.

Design characteristics of capacity of LoRaWAN (RU) vs GoodWAN

We compare capacity of up of the channel with a standard length and 20% of probability of imposing of sendings

Outputs: Capacity of up of GoodWAN channel of the gateway at 10-20 times exceeds possibilities of LoRaWAN of gateways

Application

• Retail: The field of application of IoT in retail is very wide: it is tracking of the product range, interactive interaction with buyers, marketing, analytics of purchases, mobile payments, management of a trade remaining balance and assets
• Housing and public utilities: It is used for collection of information about indications of different counters of housing and public utilities (a hot and cold water, electricity, heat, gas) with a pulse exit for accounting systems and billing of energy resources. The device counts quantity of the impulses received from the counter with a pulse exit and transfers these data to the base station with the set frequency.
