Certification documents for two unannounced PlayStation devices, model numbers CFI-Y2000 and CFI-Y2105, have surfaced. Both run Android 15, suggesting they are updates to the current PlayStation Portal streaming handheld. While one may feature an OLED screen, the second device’s purpose remains unclear, potentially linking to rumors of a native PS6 handheld.
Wi-Fi 7 is the latest wireless standard offering incredibly fast connections, currently available in the US, UK, Australia, Japan, and Mexico, with a projected 2.1 billion devices by 2028. The new technology introduces 320MHz channels, Multi-Link Operation, deterministic latency, and 4K QAM, but requires a compatible router, with prices ranging from $300 to over $1,000. While offering impressive performance, the cost of entry and limited availability in some countries are factors to consider.
Samsung's upcoming smartphones, the Galaxy F55 and Galaxy C55, have been certified by the Wi-Fi Alliance, indicating their imminent launch. The Galaxy F55 is expected to be a rebranded variant of the Galaxy M55 and may feature the Qualcomm Snapdragon 7 Gen 1 chipset, while details about the Galaxy C55 remain scarce. The certifications also reveal that both smartphones will support dual-band Wi-Fi 6, hinting at their mid-range positioning in Samsung's lineup.
The Wi-Fi Alliance has certified the new Wi-Fi 7 standard, 802.11be, promising speeds of almost 5.8 Gbps, thanks to features like increased channel bandwidth, 4K QAM, MLO, improved latency, and MU-MIMO enhancement. While backward compatible, older devices won't fully benefit from its new features. Wi-Fi 7 is ideal for 8K movies, AR/VR gaming, and smart home devices, but its short wavelengths may limit long-range performance. Some Wi-Fi 7 routers are already available, but they come with a hefty price tag, and it's advisable for most people to wait until more devices support Wi-Fi 7 and prices come down.
The Wi-Fi Alliance has announced the launch of Wi-Fi 7 Certified products, offering "near-zero" latency for real-time applications such as wireless VR streaming. Wi-Fi 7, also known as 802.11.be, introduces features like Multi-Link Operation (MLO) and Simultaneous Transmission and Reception (STR) to support near-zero latency, benefiting wireless VR by allowing devices to connect to multiple bands simultaneously for increased throughput and reliability. While this promises significant improvements, it's important to note that Wi-Fi transmission latency is just one part of the overall latency pipeline for VR, which includes rendering, encoding, decoding, and device-dependent latency.
Wi-Fi 7 devices can now be certified by the Wi-Fi Alliance, offering higher throughput, linked wireless bands for better stability, and reduced latency. The new standard allows for 320 MHz of channel bandwidth, Multi-Link Operation across 2.4, 5, and 6 GHz connections, and Multi-Resource-Unit Puncturing, potentially achieving a 5.8Gbps connection and a maximum throughput of roughly 36Gbps. Manufacturers are already touting devices pending its certification, and while consumer-level devices may not provide the full connectivity potential, Wi-Fi 7 offers significant upgrade incentives over prior generations.
The Wi-Fi Alliance has confirmed that the final Wi-Fi 7 standard will be released before the end of Q1 2024, promising multi-gigabit speeds and improved stability compared to Wi-Fi 6. Wi-Fi 7, also known as 802.11be, allows seamless switching between frequencies and offers 320MHz superwide channels, doubling the throughput of Wi-Fi 6. It also enhances transmission rates and enables networks to accommodate more devices efficiently. Hardware vendors like Intel and Broadcom have already showcased Wi-Fi 7 speeds, and more manufacturers are expected to unveil products utilizing the new standard.
