I got myself a job as a taxi driver and stuck a laptop with external GPS and external 802.11 connected to the roof for good reception.

    Prestige 2000W
    VoIP Wi-Fi Phone

    The Prestige 2000W VoIP Wi-Fi phone, compatible with IEEE 802.11b wireless standard, is a perfect solution for Voice over IP applications. It allows users to make or receive phone calls as long as they are in the coverage of IEEE 802.11b or 11g wireless Access Points. By using the Prestige 2000W, users no longer have to pay expensive communication fees and can enjoy the convenience of wireless mobility.

    The brand new application is developed to support open standard SIP (Session Initiation Protocol), which interoperates with major SIP-based call servers, IP-PBXs and various VoIP client devices. It is not only an ideal alternative for ITSPs (IP Telephony Service Providers) to deploy their VoIP services; it can also be the wireless handset, which is applied in corporate IP-PBX centric VoIP environment.

    The Prestige 2000W is very easy to use and configure. It allows users to configure with LCD screen menu or web browser. Meanwhile, with the smart auto-provisioning mechanism, ITSPs can easily deploy and manage the VoIP services. Easy-to-use and convenient, the Prestige 2000W delivers high quality voice functionality in a cost-effective way.


    Open Standard SIP v2 Support
    The call control protocol of the Prestige 2000W is based on SIP v2 (Session Initiation Protocol version 2, RFC 3261) open standard, which is interoperable with major SIP-based call servers, IP-PBXs, and other standard SIP-based client devices.

    Mobility with IEEE 802.11b Wireless Standard Compliance
    The Prestige 2000W is compliant with the IEEE 802.11b standard and interoperates with any existing 802.11b or 802.11g wireless AP and gateway. It may be used as a cordless handset for residential users or for business users in an office environment. The small form factor of the handset is easy to transport and allows users to place VoIP phone calls in public 802.11-based hot spots.

    High Voice Quality with Low Communication Costs
    The Prestige 2000W is capable of tagging features that support a service provider?s QoS (Quality of Service) planning, such ToS (Type of Service), and DiffServ. It allows gateways or central side equipment to identify and prioritize voice and data traffic. By supporting G.711 and G.729 voice compression technology, the Prestige 2000W effectively reduces bandwidth consumption caused by voice traffic.

    Enhanced Power Saving Design for Extended Standby and Talk Time
    With an improved power-saving design, the Prestige 2000W can be used for a relatively long period of standby and talk time. With an extended life for each recharge cycle, the Prestige 2000W is available where and when you need it.

    Direct IP-to-IP Call and Ad-hoc Intercom Mode Support(Optional)
    By configuring a remote IP address in the built-in phone book, the Prestige 2000W provides a direct IP-to-IP call feature when there is no intermediate SIP proxy server available in the network. The Prestige 2000W can also establish an 802.11 ad-hoc network (computer-to-computer network without Access Point), which allows users to use the handsets as wireless intercoms.

    - IEEE 802.11b support
    - Frequency band: 2.400 ~ 2.497 GHz
    - Channel: FCC Ch1~11, ETSI Ch1~13, Japan Ch1~14
    - Data Rate: 11 / 5.5 / 2 / 1 Mbps
    - Output Power: 14 + 1dBm
    - Sensitivity: -82 dBm@11Mbps
    - Operating range: Out-door up to 300m, In-door up to 75m
    - 64/128 bit WEP encryption
    - Site Survey: Scan available APs in hand set?s environment
    - Support infrastructure (public) mode and Ad-hoc mode (option)

    - SIP (RFC 3261) version 2
    - SDP (RFC2327)
    - RTP (RFC1889)
    - RTCP (RFC1890)
    - CODEC: G711, G.729a
    - DTMF detection and relay
    - G.168 echo cancellation
    - Silence Suppression
    - Voice Activity Detection (VAD)
    - Comfort Noise Generation (CNG)
    - QoS support TOS / DiffServ
    - Support outbond proxy for NAT Traversal

    Also, since Wi-fi coverage is still spotty, even inside of cities, traditional mobile service is probably still the best solution for most folks. Once Wi-fi becomes more widely deployed, then this kind of device could displace traditional mobile techs.

    Seriously though, this looks like fun, I'll have to ask the Zyxel people for one, they make cool WiFi stuff.

  • ...the question that I have is will it work with existing VoIP providers like Vonage, VoicePulse & Packet 8? If not, then wouldn't I need to have some sort of SIP gateway sitting somewhere in order to use this thing? Sounds great if you're a corporation who could afford that kind of thing. But if you're a corporation, are you really going to expose your SIP gateway to the Internet?

    Or am I just being dumb?

    It's actually just a BCM WLAN600 [bcm.com.tw] (from a Taiwanese manufacturer) that's rebranded. ZyXEL develops very few of their products themselves.
  • I could see this being neat in perhaps a corporate area or somewhere at home, where in either case you or IT has some sort of control over the WAP settings, but this whole "wardriving" nonsense (using WEP) wouldn't work.

    WAP Clients need to use a matching WEP key of the AP, therefore if this roamed to someone's AP, they'd either have to change to that person's WEP key, or disable it. Plus, what about coffee shop / BBSM / Nomadix type solutions that require authorization with a web page redirect first? Someo

    But the 2.4GHz spot in the frequency spectrum in a typical household is so crudded up already. I mean, I already have these in use in that space:

    o 802.11b network (2 APs, 4 clients)
    o Cordless phone
    o X10 video camera (for baby monitoring)
    o Microwave oven

    The X10 camera goes mostly unused nowadays due to interference from the APs. The telephone has some very annoying pops and clicks when the microwave is in use. I'd be hard-pressed to shell out many buckazoids for one of these until I was certain it worked better than my existing phone that's using that spectrum.

    Assuming there's enough recovery for corrupted packets when interference is occurring (tried to read the article to get more info, but can't get to the site as usual), I can see where it might work better than my existing phone in the presence of such interference. But I won't be in a big hurry to go buy one just yet.

    • Adding this phone in your house wouldn't add a fifth, distinct 2.4GHz competetor to your air-space. This phone would ride over your existing 802.11b (or g) network, working with it, not competing with it. Additionally, it could replace your cordless phone, reducing the cross-talk. Next, do some channel management between your AP's and the X10 to keep them away from each other, and now all you have to worry about it the microwave.

      Of course putting this in at home would require you to somehow put a VoIP

      Ofcourse the phone will use that 802.11b network rather than interfere with it.

      I read somewhere that TCP/IP and VoIP has data recovery...

    It's called a Pocket PC, a WiFi adapter, and WiFive [wifive.net]

    Wifive can connect to other wifive users or netmeeting, and if you have an IP-PSTN service, you can place calls to regular phones as well.

    Cool though that someone made an actual phone to make the process easier
  • I want to use my cell phone as a modem for my craptop, not use my craptop as a ISP for my phone.
  • If you wardrive and get on another network, the phone will send out packets tagged with 5 in the TOS field, but the network you got onto is almost certainly not going to honor the field, whether it be TOS in the packet or DSCP in the frame.

    Also, QoS in wireless as a whole in an incomplete field. Cisco's AP still can't change the underlying "time on the air" algorithm of 802.11b and thus, you can get into a priority queue on the backside, but if there are too many people associated to the AP, you aren't ge
  • With a typical 3V 1800mAh NiMH battery you would have a talk time of 2.7 milleseconds.
