Description Are you looking for affordable adapters? Look no more. This LB-Link 150Mbps Wireless USB Adapter WiFi with WPS Soft AP Hotspot among others JUMLA BEI LTD NETWORKING PRODUCTS WHAT TO CONSIDER IN USB ADAPTERS Wireless Standards The radio waves used by wireless adapters have to satisfy one of the 802.11 broadcast standards of the Institute of Electrical and Electronics Engineers (IEEE). The most recent standard in common use as of January 2013 is 802.11n, but older adapter models use the “b” or “g” standards. These standards determine the speed of data transfer at which the adapters broadcast, and all use the 2.4GHz radio frequency band. Adapters using the recent standards also support the older standards. A draft standard expected to be approved in 2013 is 802.11ac which will be able to use the less-crowded 5GHz radio frequency band. Speeds The oldest standard, IEEE 802.11b, specifies broadcast speeds of up to 11Mbps. The later model adapters broadcast at IEEE 802.11g speeds that can range up to 54Mbps. The IEEE 802.11n standard can theoretically reach speeds of 300Mbps but the adapters using it are usually slower because the radio frequencies are crowded and there is interference. The draft 802.11ac standard will theoretically be able to reach 1Gbps and will in fact be quite fast because it can operate in the 5GHz frequency band. A business can purchase adapters and routers now satisfying the 802.11ac standard to reduce obsolescence. Security Wireless adapters broadcast the signals from your computer with a range of about 200 feet. Anyone with a wireless adapter installed in their computers or laptops can pick up your signal and access your files. Securing your wireless network is especially critical for businesses protecting sensitive material and their intellectual property.To avoid this unauthorized access, wireless adapters use encryption to secure their signals. The WEP, WPA and WPA2 protocols offer password-protected and encrypted transmissions for wireless networks. Your adapter must support these protocols to use them; most do support them. The WEP protocol has some weaknesses, while the WPA2 protocol has the strongest security. links to similar products 5.0 nano adapter bluetooth Ubiquiti LAP-120 LiteAP AC Access Point are available.
