      This Statement on Schedule 13D relates to shares of common stock, $0.001 par value per share, of Metricom, Inc., a Delaware corporation (the "Issuer"). The principal executive offices of the Issuer are located at 333 West Julian Street, San Jose, California 95110.

Item 2 Identity and Background.

      WorldCom, Inc. ("WorldCom") is a Georgia corporation. The principal business of WorldCom and its subsidiaries is communications services. The principal business and principal office of WorldCom are located at 500 Clinton Center Drive, Clinton, Mississippi 39056. During the past five years, neither WorldCom nor, to the best of its knowledge, any of the directors or executive officers of WorldCom, has had any criminal convictions, and none has been subject to a judgment, decree or final order of a judicial or administrative body of competent jurisdiction enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

      Certain information pertaining to executive officers and directors of WorldCom is set forth on Annex A attached hereto and incorporated herein by reference.

Item 3 Source and Amount of Funds or Other Consideration.

      On November 15, 1999, WorldCom acquired 30,000,000 shares (the "Shares") of Series A1 Preferred Stock of the Issuer ("Series A1 Preferred Stock") from the Issuer pursuant to a Preferred Stock Purchase Agreement dated as of June 20, 1999 between the Issuer, WorldCom and Vulcan Ventures Incorporated (the "Preferred Stock Purchase Agreement"). Vulcan Ventures Incorporated ("Vulcan Ventures") purchased 30,000,000 shares of Series A2 Preferred Stock of the Issuer ("Series A2 Preferred Stock") pursuant to the Preferred Stock Purchase Agreement. WorldCom purchased the Shares for cash consideration of $10.00 per share, for an aggregate consideration of $300,000,000. The funds for the purchase of the Shares were provided from the general working capital of WorldCom.

      Dividends on shares of Series A1 Preferred Stock may, at the election of the Issuer, be paid in additional shares of Series A1 Preferred Stock. WorldCom acquired an additional 1,950,000 shares of Series A1 Preferred Stock as payment for dividends.

Item 4 Purpose of Transaction.

      WorldCom acquired the Shares for investment purposes. Shares of Series A1 Preferred Stock become convertible into common stock at the rate of 25% every six months, commencing May 15, 2002, except in the event of a change in control of the Issuer or a major acquisition by the Issuer, in which event all such shares become convertible at the option of the holder. Shares of Series A1 Preferred Stock are automatically converted into common stock in the event of any transfer of shares other than to Vulcan Ventures or to affiliates of WorldCom or Vulcan Ventures. Each share of the Series A1 Preferred Stock is convertible into one share of common stock, subject to adjustment for stock splits, stock dividends, reclassifications, certain reorganizations, mergers, sales of assets and the like. Holders of shares of Series A1 Preferred Stock have no voting rights with respect to such shares except that, as long as more than 7,500,000 shares of Series A1 Preferred Stock (as adjusted for any stock dividend, split, combination or other similar event with respect to such shares) remain outstanding, (i) holders of shares of Series A1 Preferred Stock, voting as a separate class, have the right to elect one member of the Issuer's Board of Directors and (ii) the consent of the holders of at least a majority of the outstanding shares of Series A1 Preferred Stock is required to effect certain significant corporate actions by the Issuer.

CUSIP No. 591596 10 1 Schedule 13D Page 5 of 10 Pages

      WorldCom has no present plan or proposal that relates to or would result in (i) the acquisition of additional securities or the disposition of securities of the Issuer by any person; (ii) an extraordinary corporate transaction, such as a merger, reorganization, liquidation, or sale or transfer of a material amount of assets involving the Issuer or any of its subsidiaries; (iii) any change in the Issuer's present Board of Directors or management; (iv) any material change in the Issuer's present capitalization or dividend policy or any other material change in the Issuer's business or corporate structure; (v) any change in the Issuer's charter or by-laws or other action that may impede the acquisition of control of the Issuer by any person; (vi) any change that would result in any class of the Issuer's equity securities becoming eligible for termination of its registration pursuant to Section 12(g)(4) of the Securities Exchange Act of 1934, as amended, or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association, or (vii) any similar action.

      WorldCom, however, reserves the right to acquire or dispose of shares of Series A1 Preferred Stock it holds, the common stock issuable upon conversion thereof or other shares of the Issuer's common stock or to formulate other purposes, plans or proposals regarding such shares to the extent permitted under the securities laws and deemed advisable in light of general investment policies, market conditions and other factors.

Item 5 Interest in Securities of the Issuer.

      (a) and (b). WorldCom owns beneficially 7,987,500 shares of the Issuer's common stock issuable upon the conversion of an equal number of shares of Series A1 Preferred Stock, which become convertible on May 15, 2002, representing approximately 20.5% of the outstanding shares of the Issuer's common stock (based upon 30,910,645 shares of common stock of the Issuer issued and outstanding as of April 30, 2001, as reported in the Issuer's Form 10-Q for the quarterly period ended March 31, 2001, filed with the Commission). Upon conversion, WorldCom would have the sole power to vote and the sole power to dispose of such shares.

      (c) Neither WorldCom nor to the best knowledge of WorldCom any officer or director of WorldCom has engaged in any transaction during the past sixty (60) days in any shares of the Issuer's common stock.

      (d) Not applicable.

      (e) Not applicable.

Item 6 Contracts, Arrangements, Understandings or Relationships with respect to Securities of the Issuer.

        See discussion of the Preferred Stock Purchase Agreement and the terms of the Series A1 Preferred Stock in Items 3 and 4 incorporated by reference herein.

        On November 15, 1999, pursuant to the Preferred Stock Purchase Agreement, WorldCom, Vulcan Ventures and the Issuer entered into an Amended and Restated Registration Rights Agreement (the “Registration Rights Agreement”), which gives WorldCom and Vulcan Ventures the right, subject to specified limitations, to cause the Issuer to register such amount of Registrable Securities (as defined in the Registration Rights Agreement, which definition includes the shares of common stock issuable upon conversion of shares of Series A1 Preferred Stock and Series A2 Preferred Stock) as WorldCom or Vulcan Ventures may request, provided that the anticipated aggregate offering prices of such Registrable Securities would exceed $10,000,000. The Registration Rights Agreement also provides that WorldCom is entitled to unlimited “piggyback” registration rights permitting it to include its shares of common stock in registration statements that the Issuer files from time to time.

CUSIP No. 591596 10 1 Schedule 13D Page 6 of 10 Pages

      Holders of the Registrable Securities have the right, subject to certain exceptions, to cause the Issuer to effect a registration on Form S-3 with respect to the Registrable Securities owned by such holders, provided that Form S-3 is available for such offering and the securities to be registered will be sold at an aggregate price of at least $1,000,000.

      WorldCom has agreed not to dispose of any or all of its shares of Series A1 Preferred Stock or the common stock into which the shares of Series A1 Preferred Stock may be converted except pursuant to an effective registration statement or unless the transferee agrees to be bound by the Registration Rights Agreement. WorldCom has further agreed not to sell or otherwise transfer any shares of common stock or other securities during a period specified by the underwriters of the Issuer not to exceed ninety (90) days following the effective date of a registration statement of the Issuer filed under the Securities Act of 1933, as amended, provided that all officers and directors of the Issuer enter into similar agreements.

      The foregoing descriptions are only summaries of the agreements and other documents and are qualified in their entirety by reference to the agreements and other documents themselves, which are filed as exhibits to this Schedule and incorporated herein by this reference.
