  1. 1. FEMTO Arief Hamdani Gunawan Manajemen Telekomunikasi Universitas Indonesia 10 Maret 2010
  2. 2. About Femtocell <ul><li>Simple, low cost, easy-to-install cellular access point for homes (& offices & metro areas) </li></ul><ul><li>Delivering fast, reliable service to standard phones over licensed spectrum </li></ul><ul><li>Supported in 3G and next-generation standards by 3GPP, 3GPP2, WiMAX Forum, Broadband Forum </li></ul>
  3. 3. Standards Progress <ul><li>April 2009: Release 8 provided end-to-end UMTS standard, with Broadband Forum management data model </li></ul><ul><li>Release 9 provided feature enhancements for UMTS and end-to-end LTE femtocell support </li></ul><ul><li>Phase 1 cdma femtocell standard expected shortly </li></ul><ul><li>Phase II features are under consideration now </li></ul><ul><li>Phase 1 expected for completion </li></ul><ul><li>Phase II to include advanced network features and air interface optimization </li></ul>
  4. 4. Femto Standards Allow Mixed Vendor Deployment
  5. 5. Introduction <ul><li>As the revenues from voice tend to diminish, high competition forces mobile operators (MOs) to seek new revenue generating sources through innovation in services and technologies. </li></ul><ul><li>The commercialization of femtocells was investigated in 2008 (through tenders, technical trials, and business models) by MOs worldwide. </li></ul><ul><li>Femtocells or femto access points (FAPs) are miniature base stations connected to an MO’s network via a broadband connection (e.g., asymmetric digital subscriber line [ADSL]), typically designed for use in residential or small office/home office (SOHO) environments </li></ul>
  6. 6. Femtocell Standards <ul><li>Most air interfaces included in the global ITU-R IMT family have active programmes to develop standards for femtocells. These include: </li></ul><ul><ul><li>3GPP standards for Home Node-B, which is a WCDMA femtocell. Both FDD and TDD options are likely and a TD-SCDMA variant is also planned. </li></ul></ul><ul><ul><li>3GPP standards for Home eNode-B, which is an LTE femtocell. Both FDD and TDD options are envisaged. </li></ul></ul><ul><ul><li>3GPP2’s programme for femtocells for cdma2000, cdma2000 1x, HRPD, 1x EV-DO and UMB. </li></ul></ul><ul><ul><li>WiMAX Forum’s programme for WiMAX femtocells based on IEEE standards. </li></ul></ul><ul><li>In all cases femtocell standards will support deployments in all of the existing licensed spectrum bands in which macrocells operate. </li></ul>
  7. 7. Important 3GPP Standards <ul><li>3GPP TR 25.820, “3G Home NodeB Study Item Technical Report. </li></ul><ul><li>3GPP TS 22.220, “Service Requirements for Home NodeBs (UMTS) and eNodeBs (LTE). </li></ul><ul><li>3GPP TS 25.467, “UTRAN Architecture for 3G Home Node B (HNB); Stage 2 UTRAN Architecture for 3G Home NodeB (HNB). </li></ul>

  10. 10. Human Protection (1/2) <ul><li>Since femtocells are in essence base stations, public concern regarding the levels of RF radiation may appear. </li></ul><ul><li>According to 3GPP TS25.104, the maximum output power of FAPs should range between 17–20 dBm (without/with transmit diversity or multipleinput multipleoutput [MIMO]). </li></ul><ul><li>In addition, FAPs must comply with the guidelines for human exposure to electromagnetic emissions issued by the International Commission on NonIonizing Radiation Protection (ICNIRP) and other relevant regulatory authorities. </li></ul>
  11. 11. Human Protection (2/2) <ul><li>Given the low output power of FAPs, they could be considered to have the same level of radio frequency (RF) exposure risk as WiFi access points, commonly used in home/office environments, thus facilitating wide market adoption. </li></ul><ul><li>In this context, MOs could be relieved of reporting (to a regulator) femto base station locations and functional characteristics (e.g., operating frequency, output power, antenna polarization). </li></ul>Class license and/or Certification can be used as the approach to provide human protection
