Lexar 2GB Wi-Fi Memory Card

Really a great initiative.. .Love to see its Market success. As i used to say....all the devices soon be part of Internet World..to communicate directly (not via any computer)... Surely soon IPv6 enabled WiFi Memory cards will be available.

I find the following pic from Lexar website:

Lexar is giving digital photo enthusiasts the opportunity to “cut the cord” with the introduction of its Shoot-n-Sync Wi-Fi memory card - a convenient wireless solution for uploading digital photos to computers as well as sharing them via social networking and photo-sharing websites.

The 2GB memory card, compatible with SD-compatible digital cameras, records and stores digital photos in a camera just like a standard memory card, but adds the time-saving convenience and simplicity of wireless uploading from camera to computer - and directly to the Internet.
With its advanced Wi-Fi connectivity, the Lexar Shoot-n-Sync Wi-Fi memory card is a great product for a wide range of photographers from bloggers, web surfers, and social-networkers to busy parents, traveling executives, and students. The Lexar Shoot-n-Sync Wi-Fi memory card provides a simple and convenient solution for managing all their digital photos. Instead of removing the memory card from a camera, transferring it to a reader, connecting the reader, and then dragging each individual photo onto the computer, the Lexar Shoot-n-Sync Wi-Fi memory card offers users a much simpler solution.
As an Eye-Fi Connected product, the Lexar Shoot-n-Sync Wi-Fi memory card features Eye-Fi technology and connects to Eye-Fi’s web service to wirelessly and automatically upload photos from a digital camera to the web and to a computer. Eye-Fi is dedicated to building products and services that help consumers navigate, nurture and share their digital memories. After the brief initial installation of Eye-Fi Manager software on your PC, the card is ready to wirelessly download copies of any photos stored on it, automatically to your computer, as soon as it comes within range of your home computer’s wireless network. Without removing the card from the camera, users can back up photos to a computer or transfer them to photo-sharing, social networking, or blog sites. After the digital photo copies are sent, all a user has to do is approve the transfers and they can be instantly shared with the world.
“Lexar is committed to delivering innovative products that enhance people’s enjoyment of digital photography. The Lexar Shoot-n-Sync Wi-Fi memory card not only provides our customers the reliability and quality of Lexar memory, but the opportunity to enjoy a new level of wireless convenience - free from the hassles of cables and greatly simplifies transferring photos from camera to PC,” said Manisha Sharma, Lexar director of product marketing.
Compatible with both Windows and Mac operating systems, the 2GB Lexar Shoot-n-Sync Wi-Fi memory card will ship in October.

MPLS & Relevance in WiMax

WiMAX is not dependent on MPLS but the IP base infrastructure. ...but as this technology need to lead in the market & compete with its rival technologies. ...& offer Multiplay services...that hasnt been offer before...The Technology developers.. .combine all the best of the Technologies to built the Converged/Unified Network.
Aim of WiMAX is to offer,
  • Broadband Wireless Access (Huge amount of bandwidth per user) .. so that every user can enjoy the Voice/Video/ Data Services over the same Last mile by spending minimum possible $$$.
  • More Strong Coverage: To target Metropolitan areas, so that single BS can cover more n more business area.

For offering good services...with the above mentioned aim..it is necessary to have all three segments of networks with the huge capacity to handle VAS like Voice, Video, Data. These segments are,

Access: WiMAX RF interface offer good bandwidth using OFDMA & its varients.

Distribution/ Aggregation: WiMAX recommend Metro Ethernet for backhualing WimAX users traffic to ASN Gw....but u can also us Ethernet Microwave, E0SDH or Existing TDM/ATM network.

Core: Currently available Core network technologies are TDM, IP, FR/ATM, MPLS. MPLS is the most powerfull & most widely adopted technology in the World. Currently worldwide oeprators are already using MPLS in their existing 2G or 3G core...along with TDM by some operator..So WiMAX chooses best of the best methodologies to compete in the market.

Now the second question can be What is MPLS & What it can do for any network (including WiMAX)? Check the following detail list of MPLS related documents present at Xpedient Portal Files Section.
