Understanding how environmental factors can affect range is one of the key aspects to deploying a radio frequency (RF) solution. This paper will provide a high-level overview of the factors that can affect RF range, including hardware selection, environmental factors, frequency ranges, and proper implementation.
Whether you are looking to connect across 10 meters in a crowded hall or 10 kilometers outdoors, the environment plays a significant role in the maximum range that can be achieved. This white paper explains how range numbers are calculated and discusses the factors that limit range.
IEEE and industry standards define how a Wi-Fi radio interoperates with a wireless LAN infrastructure, and the Wi-Fi CERTIFIED™ seal ensures interoperability. For many organizations that rely on mobile computers, however, Wi-Fi CERTIFIED is not enough. These organizations need assurance that their mobile computers will interoperate with a Cisco wireless LAN infrastructure and support Cisco wireless LAN innovations for enhanced security, mobility, quality of service, and network management. The Cisco Compatible seal gives organizations the assurance that they seek.
Many medical devices require persistent network connections. Providing such connections over Wi-Fi in a hospital can be a challenge.
When a medical device is mobile, the Wi-Fi radio in that device must switch, or roam, from one infrastructure endpoint to another. Fast and effective roaming is essential to maintaining a persistent network connection and ensuring the reliable operation of the applications that rely on such a connection.
This white paper explains how roaming works and how roaming can be optimized to ensure the reliable operation of client devices, including medical devices, that use Wi-Fi in a hospital.
With throughput much greater than that available with previous wireless local area networking (WLAN) standards, the IEEE 802.11n standard has had a significant impact on the WLAN, or Wi-Fi, industry. Most of today’s WLAN infrastructure products support 802.11n, and support on client devices is growing.
Present in nearly all wireless phones and an ever-growing number of wireless devices, Bluetooth technology has become an exceptional performer for audio and data transmission. Bluetooth 4.0 introduces Bluetooth Low Energy (BLE), a new protocol that allows for long-term operation of Bluetooth devices in low-volume data transmission. BLE enables smaller form factors, better power optimization, and power cells that last for years on a single charge.
