WiFi 7 MLO multi link operation

Compex Systems (Compex), a global leader in wireless communication technology, is taking Wi-Fi 7 to new heights with an innovative connector design for Multi-Link Operation (MLO). This breakthrough enables seamless deployment of MLO across off-the-shelf platforms, including those with Intel x86 and ARM processors (e.g. NXP and Marvell), eliminating the need for custom-made host boards and unlocking the full potential of Wi-Fi 7 features for a wider range of users and applications. Multi-Link Operation (MLO) is a key performance advantage of Wi-Fi 7 (802.11be), setting it apart by allowing the routing and aggregation of throughput across multiple radio links in different frequency bands. It enables data to be routed through the least congested links, improving overall latency and reliability. MLO can also aggregate bandwidths from more than one wireless link, enhancing throughput and network performance. It is ideal for bandwidth-intensive and real-time applications such as 4K/8K video streaming, cloud gaming, [...]

Raspberry Pi product series explained

30 October 2024 at 18:31

As our product line expands, it can get confusing trying to keep track of all the different Raspberry Pi boards out there. Here is a high-level breakdown of Raspberry Pi models, including our flagship series, Zero series, Compute Module series, and Pico microcontrollers.

Raspberry Pi makes computers in several different series:

  • The flagship series, often referred to by the shorthand ‘Raspberry Pi’, offers high-performance hardware, a full Linux operating system, and a variety of common ports in a form factor roughly the size of a credit card.
  • The Zero series offers a full Linux operating system and essential ports at an affordable price point in a minimal form factor with low power consumption.
  • The Compute Module series, often referred to by the shorthand ‘CM’, offers high-performance hardware and a full Linux operating system in a minimal form factor suitable for industrial and embedded applications. Compute Module models feature hardware equivalent to the corresponding flagship models but with fewer ports and no on-board GPIO pins. Instead, users should connect Compute Modules to a separate baseboard that provides the ports and pins required for a given application.

Additionally, Raspberry Pi makes the Pico series of tiny, versatile microcontroller boards. Pico models do not run Linux or allow for removable storage, but instead allow programming by flashing a binary onto on-board flash storage.

Flagship series

Model B indicates the presence of an Ethernet port. Model A indicates a lower-cost model in a smaller form factor with no Ethernet port, reduced RAM, and fewer USB ports to limit board height.
