Executive

18、summary On the basis of selected applications and use cases in the millimetre wave band, especially in the V- and E-bands, and based on operators expectations as defined in ETSI GS mWT 002 i.1, appropriate antennas requirements have been identified. Several deployment scenarios as well as the releva

19、nce of antenna features. A current technology review and a status review of existing standards put in perspective the challenges that the industry is facing with those new requirements. Introduction The number and quality of services that can be offered in a given band highly depend on the efficient

20、 use of spectrum which is closely related to the performance of the antennas. Antenna functions are key when it comes to effective spectrum management and consequent service availability. The present document reflects a common agreement on how best to make spectrum available for the different use ca

21、ses in order to avoid delays, confusion, and missed opportunities. Antenna requirements for different mm-wave applications and use cases vary significantly. The variety of antenna options and requirements are of great relevance for different applications and use cases. While strict licencing and tou

22、gh antenna quality requirements may be the best solution in one application, another use case may call for a more self-organized deployment with antenna features that help avoid interference.

Integrated antennas mean simplified logistics, easier installation and no electrical interface thats exposed

36、 to the environment. (See also clause 3.1). 5.3 Antenna Requirements for various deployment scenarios 5.3.0 Introduction When looking at the enablers for wireless transmission applications described in ETSI GS mWT 002 i.1 all use cases have a need for high frequency re-use and network densification,

37、 require an optimized TCO and rapid time-to-market of broadband services, and most use cases call for “non-telecom“-shaped equipment form factor/aesthetics. Network design and implementation practices however indicate that the relevance of specific antenna features depends on application, use case a

38、nd deployment scenario. This clause maps the use cases and applications described by ETSI GS mWT 002 i.1 to the three most relevant deployment scenarios and describes with which antenna features their specific challenges can be addressed. 5.3.1 Rooftop Installations Figure 2 Rooftop installations ar

39、e well supported by conventional antennas and current regulations. When equipping macrocells with mm-wave backhaul solutions, the motivation is typically higher throughput per cell site compared to the ones of legacy networks. Point-to-Point LOS radio link and regulation schemes that ensure interfer

40、ence-managed operation are preferred. Aesthetic concerns apply only in some places. For most installations a split-mount radio unit form factor is acceptable. ETSI ETSI GS mWT 006 V1.1.1 (2015-12)12 To reach last-mile distances of up to 5 km and target availability medium gain (40 dBi to 50 dBi) ant

41、ennas of ETSI class 2 to 4 are required with long known interference-managed operation. As pre-aggregation sites have to accommodate more and more backhaul links, antennas with very high frequency re-use capabilities, namely higher class antennas with better sidelobe suppression or dual polarization

42、 become more probable. Auto-alignment of radio units might be handy, in case it expedites drastically the installation time over relatively long transmission distances. This is done one-time during installation and does not justify beamsteering functionalities. Although temporary transmission links

43、for special events and emergency are not mandatorily installed on rooftop sites only, requirements for this use case are comparable to roof top installations. The main difference is that such links need to be quick to install which makes auto alignment functionalities more important. Typical roof to

44、p applications: Macro-cell mobile backhaul application (mobile network upgrade (existing cells) and expansion (new cells). Fronthaul for macro cells application (mobile network upgrade (existing cells) and expansion (new cells). Temporary infrastructure application (Special events and Public safety)

45、. TV signal relay application. Next-generation mobile transmission applications. Business-to-business application. Broadband connectivity to governmental buildings. 5.3.2 Street Level Installations Figure 3 In urban and sub-urban environments outdoor operator-managed small cells are placed at lamppo

46、sts, outside buildings walls, payphones, notice boards and similar public spots. This introduces a few new requirements for the backhaul solutions and antennas in particular. Roll-out has to be easy and fast, due to the “non-telecom“ professional working environment. Therefore, automation mechanisms

47、, such as self-alignment by beam-steering looks to be quite significant for efficient small-cell backhaul. If beemsteering is not available, low gain antennas with a wide opening angle make alignment easier. This goes along with the fact that only relatively short distances have to be covered. In lo

48、cations that are fully or partially isolated by surrounding obstacles (trees, buildings, hills, etc.) interference is limited by these obstacles and the directivity of the antenna becomes less significant. A trade-off between a highly demanding RPE and the cost/size/weight of the antennas, compatibl

49、e with the constraints is advisable. ETSI ETSI GS mWT 006 V1.1.1 (2015-12)13 At street-level radio propagation conditions express a more dynamic behaviour compared to roof top installations due to the increased phenomenon of multipath. In addition, clear LOS conditions are not always found because of obstacles (e.g. signposts) or could be variable (e.g. seasonal trees foliage). A wireless transmission technology that supports PtP/PtMP topologies, nLOS/NLOS radio propagation conditions and building penetration is desired.
