2ad651856c72fbf2972ae7a071719ef3 | 102 079 | 4.1.1 Position of Secrétariat d'Etat à I'Industrie | The Secrétariat d'Etat à l'Industrie expresses its concerns about the premature adoption of the present document for the following reasons: • a permanent confusion about the exact purpose of the HIPERMAN system exist throughout the document. Indeed, this system is either presented as a competitor to the licensed FWA or... |
2ad651856c72fbf2972ae7a071719ef3 | 102 079 | 4.1.2 Reservations made on behalf of TC SES chairman | 1) Background The proposed Fixed Wireless Access (FWA) system under consideration would require from 120 MHz to 150 MHz of spectrum to be allocated to Fixed Services (FS) in the frequency band 5,725 GHz to 5,875 GHz. In ITU-R Region 1, the current primary allocation in the 5,725 GHz to 5,875 GHz frequency band is Fixed... |

2ad651856c72fbf2972ae7a071719ef3 | 102 079 | 4.2.1 Short background information | |
2ad651856c72fbf2972ae7a071719ef3 | 102 079 | 4.2.1.1 System description | The system is an access network, primarily intended for the delivery of IP-based services ("Internet"). Three system architectures have been considered: • PMP; • APMP; • Mesh. |
2ad651856c72fbf2972ae7a071719ef3 | 102 079 | 4.2.1.2 Applications | The system is intended for access and bridging IP applications embracing voice and broadband data services to SMEs, SOHOs and residential customers. The system is intended to fill the demand for broadband "Internet" where wired (DSL and cable) solutions are unavailable or not cost-effective. It is specifically designed... |
2ad651856c72fbf2972ae7a071719ef3 | 102 079 | 4.2.1.3 Considered technologies | |
2ad651856c72fbf2972ae7a071719ef3 | 102 079 | 4.2.1.3.1 PMP | The PMP architecture is proven, as it has been widely deployed in licensed bands [18] as access network and cellular network. It has further been used in licence-exempt applications. The use of repeaters and relays in this type of network has also been implemented. |
2ad651856c72fbf2972ae7a071719ef3 | 102 079 | 4.2.1.3.2 Any-Point to Multipoint | The Any-Point to Multipoint architecture is a hybrid network topology between PMP and Mesh. Like in the Mesh topology, any node can route traffic to its neighbours and can therefore serve as the Access Point for new nodes in the network. Like in the PMP topology, nodes attach to a specific Access Point in the network, ... |
2ad651856c72fbf2972ae7a071719ef3 | 102 079 | 4.2.1.3.3 Mesh | The Mesh architecture concept is not new either, though it has solely been used in military, mostly highly mobile applications to obtain highly redundant robust networks. Very recently, it has been introduced in licensed FWA systems above 11 GHz, using engineered point-to-point links. The application of mesh architectu... |
2ad651856c72fbf2972ae7a071719ef3 | 102 079 | 4.2.1.4 Short market information | FWA systems are designed to provide broadband data and voice services to SMEs, SOHOs and residential users. With fixed broadband connections, users can take full advantage of all the services available over the internet including email, educational materials, entertainment and more. However, today's demand for broadban... |
2ad651856c72fbf2972ae7a071719ef3 | 102 079 | 4.2.1.5 Market size, forecasts and timing | Residential fixed broadband subscribers, already numbering more than 10 Million world-wide are expected to grow more than ten-fold by the end of 2005 according to Ovum. Fixed broadband data services can be delivered over twisted pair telephone wires (xDSL), cable TV wires (cable modem), satellite dishes and through fix... |
2ad651856c72fbf2972ae7a071719ef3 | 102 079 | 4.2.1.6 Spectrum requirement and justifications | The systems may use 5 MHz, 10 MHz or 20 MHz channelization, which is necessary to obtain sufficiently high data rates. In single cell deployments, usually one or two channels suffice. In large area multi-cell deployments a common number of channels used per operator is 4. For backhaul an additional channel may be requi... |

2ad651856c72fbf2972ae7a071719ef3 | 102 079 | 4.2.2.1 Radiated power | The envisioned power is 1W mean EIRP, equal to the current regulation in 5,470 GHz to 5,725 GHz [11]. It is required to achieve sufficient link-budget margin in order to deploy PMP systems with economical cell-sizes and to initially deploy mesh system. For mesh systems, as the customer density increases, the EIRP value... |
2ad651856c72fbf2972ae7a071719ef3 | 102 079 | 4.2.2.2 Transmitted bandwidth | For the purpose of illustration, three channel bandwidths have been used in the present document: 5 MHz, 10 MHz and 20 MHz. Using 20 MHz channelization, the -20 dBr transmitted bandwidth is 22 MHz or less. The -3 dB transmitted bandwidth is less than 19 MHz. Using 10 MHz channelization, the -20 dBr transmitted bandwidt... |
2ad651856c72fbf2972ae7a071719ef3 | 102 079 | 4.2.2.3 Frequency considerations | This type of system requires transmission technology that is both low-cost, provides a reasonable range and a reasonable amount of spectrum to operate in to achieve the data-rates necessary to provide broadband services. Due to the high cost and low range of above 11 GHz RF technology, only sub-11 GHz spectrum is suita... |

2ad651856c72fbf2972ae7a071719ef3 | 102 079 | 5 Main conclusions | FWA providing narrowband connections (< 256 kbps) is not economically viable in Western Europe with wired telecommunications infrastructure reaching the vast majority of the population. In some remote areas narrowband FWA could provide a reasonable alternative to wires but this market is very small and not really attra... |
accc253622be90f5d04394f3868b00dc | 102 074 | 1 Scope | The present document aims at further assessing the rationale (pros/cons) and status of mixed mode operation in MP systems in the context of inter system co-existence ( with the specific example of EN 301 213-3 [1] "most stringent mask" requirement in mind ), envisaging various situations, producing conclusions and reco... |

accc253622be90f5d04394f3868b00dc | 102 074 | 4 General | In a recent amendment to EN 301 213-3 [1], a type C transmitter emissions mask limit has been added. This mask has been proposed as being appropriate for 64 QAM emission limits in the broadband fixed wireless access point-to- multipoint (PMP) operational environment. The specification further requires that when operati... |
accc253622be90f5d04394f3868b00dc | 102 074 | 5 Coexistence system considerations | Inter-System coexistence requires consideration of two primary interference scenarios. The first of these is interference across a boundary that separates the geographical deployments of two operators. This is primarily a co-channel interference situation and adjacent channel impairments are quite secondary. The second... |
accc253622be90f5d04394f3868b00dc | 102 074 | 6 Coexistence system studies | Recently, a number of coexistence system studies (see reference [2]) have been published that examine NFD and related guard band requirements for acceptable same-area/adjacent-frequency deployments. Summary descriptions of these system studies may be found in [3]. While each of the studies has employed quite different ... |
accc253622be90f5d04394f3868b00dc | 102 074 | 7 NFD emission mask estimates | A preliminary estimate of the NFD values to be expected from the emissions masks can be achieved by simply performing a numerical integration of the power allowed in each adjacent carrier bandwidth relative to the power allowed within the bandwidth of the transmitting carrier. There are two components associated with t... |
accc253622be90f5d04394f3868b00dc | 102 074 | 8 NFD simulation estimates | NFD estimates based on emission masks can be quite misleading as the masks are configured from straight-line segments (on a dB basis). Actual levels of emissions, still falling within the mask, may have a quite different detailed set of emission values that may result in significantly different estimates for NFD. The p... |
accc253622be90f5d04394f3868b00dc | 102 074 | 9 Conclusion | Coexistence NFD requirements have been examined for same area/adjacent operator CS to TS operational compatibility. It is estimated that an NFD of 50 dB or greater is required, a value consistent with that reported in other system studies. Both numerical mask integration and inter-modulation simulation against measured... |
