Frequently Asked Questions

Each SX1257/50/55 chip can digitize almost 1 MHz of spectrum, therefore two are required typically to achieve 8 channels with a channel separation of 200 kHz or so. The limitation of using a single SX1257/50/55 chip and one SX1301/08/02 chip is that you can only digitize 1 MHz of spectrum (and not 2 MHz) and can only build a 4 channel modem since the channels are spaced 200 kHz apart.

A PicoCell Gateway is typically a small, localized device or system used to manage cellular network connections, specifically for the purpose of improving cellular coverage within a specific, limited area, such as a building or a campus. It can be considered part of a femtocell or small cell network, which is a low-power, short-range cellular base station that connects to the internet or a private network to provide improved service in areas where traditional cell towers might not provide adequate coverage. Key features of a PicoCell Gateway include:
  • Local Cellular Coverage: It enhances signal strength in areas with poor network coverage, such as indoor locations or remote areas.
  • Internet Backhaul: It connects to the internet via broadband or other backhaul methods to route calls, data, and texts through the larger cellular network.
  • Improved Data and Voice Quality: With a PicoCell Gateway, users experience better data speeds, voice clarity, and fewer dropped calls.
  • Private Network Support: In some cases, the PicoCell Gateway can provide a private network for a company or home, ensuring more secure communication.

The CoreCell Gateway is a term often associated with advanced telecommunications infrastructure, specifically in the context of 5G and small cell networks. While the exact definition can vary depending on the vendor or context, a CoreCell Gateway generally refers to a key component in the deployment of small cells, providing integration and management between the Radio Access Network (RAN) and the core network. Key Functions of a CoreCell Gateway:
  • Aggregation and Processing: It aggregates data traffic from multiple small cells (like picocells, microcells, or femtocells) and processes it for routing to the core network.
  • Network Optimization: Enhances the performance of small cells by optimizing communication, managing interference, and ensuring efficient use of resources.
  • Seamless Connectivity: Bridges the small cell environment with the larger cellular network, ensuring uninterrupted service for users.
  • Edge Computing Integration: Many CoreCell Gateways integrate edge computing capabilities to process data closer to the user, reducing latency and improving performance for applications like IoT and real-time analytics.
  • Backhaul Support: Provides backhaul connectivity (wired or wireless) to the core network, facilitating the transfer of large volumes of data.
