Information About SpectraLink NetLink Telephones
For the best integration with the Cisco UWN solution, SpectraLink NetLink Telephones require an extra operating system configuration step: enable long preambles . The radio preamble (sometimes called a header) is a section of data at the head of a packet that contains information that wireless devices need when sending and receiving packets. Short preambles improve throughput performance, so they are enabled by default. However, some wireless devices, such as SpectraLink NetLink phones, require long preambles.
