Wireless LAN Part
The wireless method used for the WIP-5000M is the IEEE802.11b Wireless LAN
specification at the 2.4GHzbandwith.
Also, the major components of wireless LAN are the Prism2.5 of Intersil, and are
composed of 4 components, such as ISL3984(PA), HFA3783(IF I/Q MOD. DEMOD.),
ISL3685, and MAC/BBP ISL3873B.
CPU, VoIP (SIP) Part
The CPU used for the WIP-5000M is a combined type that the RISC and DSP
functions are combined into one processor. That is, there is no need for a separate
DSP when processing voice for the Voice over WLAN. Also, the internal SRAM
allows the program performance possible without a separate external memory.
The major functions for the main processor are summarized as the wireless LAN,
