Specs and Design Info

As mentioned earlier, the WSKP100 is manufactured by SMC's parent company Accton and will also appear as the EdgeCore WM4201 and Belkin F1PP000GN-SK. A close comparison of the phone with photos of the Netgear phone, however, confirms that the SPH101 is not the same design.

The phone came in a box marked with an "smc-asia.com" URL and had neither the Wi-Fi mark shown in Figure 1, nor any FCC ID marking. So I got out my dissection kit and opened it up. Figure 2 shows that the design is based around a TI OMAP 1710 single-chip cell phone application processor.

The other larger chips visible in the photo are:

  • TI TPS65013 Multi-Channel 1-cell Li-Ion Power Management chip
  • TI TSC2101 Audio Codec w/ Integrated Headphone Speaker Amp & Touch Screen Controller
  • Samsung K4S54163 256Mbit SDRAM
  • Intel Z422070C (couldn't find this)

I didn't remove the board from the case, since it seemed to resist my gentle efforts. So I didn't get a look at the other side of the board. I suspect all that I would see, however, is the 1.8"CSTN, 65K color 128 x 160 LCD screen with LED backlight and keypad contacts. Also not shown in the picture is a buzzer that nestles in the back cover for the phone's silent vibrate mode.

I also didn't remove the shield over the radio section, but given the other TI components, I'm guessing I'd find a TI WL1251 WiLink 4.0 single-chip 802.11b/g radio. The SMC User Guide specs the phone's radio at a decent RF output power of 16 dBm (40 mW) for 802.11b and 12 dBm (16 mW). This, coupled with a 5.5 dBi antenna helped to give the phone decent range (more later).

The phone is powered by a removable Li-Ion 3.7 V minimum 1100 mAH battery that the phone's User Guide said will supply "Use Time: 3 hrs" and a standby time of 50 hrs. However, I got nowhere near that in a couple of days of use with overnight recharges in between. I found that the phone was pretty much tapped out after about 8 hours of standby and perhaps 15 minutes of calling.

The User Guide says the battery will fully charge in three hours, but the charge indicator that appeared on the phone screen never showed higher than a half charge. However, when the phone was powered up, the battery indicator on the Main screen showed a full charge. One other battery-related issue is that I found the back cover a bear to open with the battery inserted. I had to pry it open using a screwdriver, which fortunately didn't seriously damage the relatively-thin battery compartment cover.

Finally, while browsing through the Settings > Information menu, I came upon a "Powered by TrollTech.com" logo. So I guess it's safe to assume one of TrollTech's products is at work in the WSKP100.
