Inside Story

The internal pictures on the FCC website provide a detailed view of the GPE's construction. Figure 4 shows an open-case view, with the dual internal patch antennas clearly visible in the left-hand module.

With the antenna board removed, the power supply is visible, as is the heater module positioned over the boards (Figure 5).

Once the heater module is removed, you can see the main board with separate mini-PCI radio (Figure 6).

The GPE uses an Intel-based design, more similar to the unannounced WAP54GP than the standard Broadcom-based WAP54G. Figure 7 shows an Intel IXP425 Network Processor, Kendin KS8721 supplying the 10/100 Ethernet port and one of the two Dynachips D98SD12816 RAM chips. The other is on the bottom of the board along with a single Intel TE28F640 Flash chip.

Figure 8 completes our tour of the GPE's innards, showing the mini-PCI 802.11b/g radio based on the Ralink RT2560 802.11b/g Baseband/MAC processor and RT2525 tranceiver.
