Beam Modem Architecture for Cellular Data Compression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In regions with limited or expensive data connectivity, such as China, Cuba, and parts of Africa, users face challenges in accessing data services due to lack of local SIM cards, high costs, and restricted internet access, making it difficult to connect to external web services without direct network connections.
Innovation Solution
A communications system comprising a client device, a beam modem, and a beam API server, where the client device generates encrypted web requests that are transmitted via short-range transceivers to the beam modem, which connects to the API server through a cellular transceiver, allowing access to external web services by reducing and compressing response data to optimize data transfer in limited networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users access external web services in regions with limited connectivity, then service accessibility is improved, but data consumption increases
Solution Approach 1:
The patent introduces a beam modem as an intermediary device between the client device and external web services. The beam modem receives requests from the client device, forwards them to web services, receives responses, and then transmits compressed versions back to the client device. This intermediary role allows the system to access external services while managing data consumption through compression and selective data transmission.
Solution Approach 2:
The patent applies parameter changes by compressing response data before transmission back to the client device. The beam modem modifies the data parameter by reducing its size through compression algorithms, thereby maintaining service accessibility while reducing the quantity of data transmitted over the limited connectivity network.
2Productivity
If data is compressed and reduced, then data transfer efficiency is improved, but processing complexity increases
Solution Approach 1:
The patent extracts the compression and data processing functions from the client device and places them in the beam modem. By taking out these complex processing tasks from the client device, the system improves data transfer efficiency while managing processing complexity centrally in the beam modem rather than requiring complex client-side processing.
3Reliability
If local SIM cards are obtained in regions like China, then network access is improved, but cost and availability constraints worsen
Solution Approach 1:
The beam modem provides universal network access capability that works across different regions and network conditions. Rather than requiring separate local SIM cards for each region, the beam modem serves as a universal interface that can connect to various networks, thereby improving network access reliability while overcoming availability constraints in regions where local SIM cards are difficult to obtain.

AI summary
A communications system provides access to services when direct Internet connectivity is not practical. The system includes a beam modem and a beam API server. The beam modem receives a web request from a client device through a short range interface, modifies the request, and transmits the modified web request to the beam API server via a cellular connection. The beam API server then extracts an endpoint address and request data from the web request and determines an external web service from the endpoint address. The server transmits the request data to the external web service and, after receiving a response to the request data, reduces the size of the response data and sends it back to the beam modem via the cellular connection. The beam modem converts the response data to client device readable form and transmits it to the client device via the short range interface.
