Introduction

RJIL will provide truly ubiquitous coverage across all geographies of interest such that a customer shall by and large never experience out of service scenarios within the designed coverage area and all offered services shall be available while transitioning through the network across multiple cell boundaries. Coverage holes and hot spots will be covered by using additional network elements like Small Cells. These Small Cells will complement for coverage, capacity and quality to support in ubiquitous coverage of LTE services for both Outdoor & Indoor coverage. RJIL will implement the Indoor Small Cells to provide dedicated Indoor Coverage inside all the important categories of buildings across PAN India.

Purpose

The purpose of this document is to illustrate End to End Indoor deployment Process, Planning & Design criteria, Indoor Installation scenarios, backhaul requirements & OSP requirements for providing indoor coverage across all the R4G Circles. This document illustrates the following:1. End to End Deployment Process flow with tools involved. 2. Different coverage solutions with installation scenarios with OSP Details. 3. Connectivity diagrams for all the Indoor Solution Deployment Scenarios. Following is building selection criteria for circle teams when selecting the building to provide dedicated Coverage using Indoor Small Cells. 1. 2. 3. 4. 5. 6. 7.

Buildings which attract mass movement/high footfall of people. These are unique buildings across PAN India in different circles. Providing adequate coverage would not be possible through outdoor sites. These buildings would have either poor coverage or partial coverage. These buildings are good revenue source from business perspectives. Presence of any top 2 Operators on these buildings. Buildings as selected & directed by Our Business team where we expect assured revenue.

The Indoor Small Cells have many advantages as compared to old traditional DAS system, those points are listed below:      

Very Cost Effective solution MIMO solution to have better throughputs Easy to install Less integration time (Plug & Play) Easily scalable (Capacity) Real time monitoring & Easy for operations

Each solutions illustrated in this document further will differ widely for different types of site specific requirements depending on actual site conditions. User teams to evaluate, adapt & evolve the specific site solutions suiting their requirements.

LTE & Wi-Fi Implementation Strategy for Indoor

LTE being the prime service to ensure the coverage & quality, RJIL will provide LTE coverage in 100% carpet area inside each building. Indoor coverage should be available in all public & commercial buildings, malls, airports, railway stations, offices, hotels and any other potential places of human habitation and movement. Wi-Fi coverage will be provided in HOT SPOT locations inside the building to ensure the traffic offload of LTE network & to offer other JIO applications & services. On an average 2530 % of the area will be covered. The AirVelocity product for indoor Small cell supports both LTE & Wi-Fi in the same form factor. The Small Cell with combined platform will be installed in the Hot Spot locations where the Wi-Fi coverage is required along with the LTE services. The combined product will be available by April, 2015. The LTE only product is expected by mid of Feb, 2015, has the additional PoE port functionality by which the separate Wi-Fi AP can be powered up & backhauled. This will be a time gap arrangement till the time the combined AirVelocity product is available commercially. There will be some buildings where the permission will not be available for separate Small Cell network implementation since the existing DAS wiring has been already done by other operators. In such buildings the LTE coverage will be provided through the DAS sharing. Initially only 841 RCOM sites are considered for the DAS sharing across PAN India. It is preferred & decided to have Small Cell 2T2R network to ensure the throughput, quality inside the building as compared to traditional 1T1R DAS network.

10 Indoor Planning and Design Considerations o Design Philosophy The objective is to develop a set of inputs that will be used to plan an in-building coverage solution to provide reliable and ubiquitous service at all potential areas of the venue that have been mutually agreed upon among all associated parties. The following three key design goals are to ensure the following:o Indoor solution shall be sufficiently dominant within 100% of the venue area thus improving coverage, quality and realizable air-interface capacity. o The overlap percentages shall remain within specified targets under all circumstances so that planned capacity numbers can be realized. Excessive overlap may significantly degrade achievable RF quality (SINR). o The indoor solution shall be seamlessly integrated into the existing macro network in a coordinated manner without causing excessive interference or otherwise impacting the macro network KPIs. The planning design shall ensure that the following design targets: o Core Sectors (Very High Indoor Coverage Dominance) o RSRP (best venue server) > RSRP (best macro server) + 15dB for 100% area. This will ensure that core sectors will not have any handover relationship with macro sectors. o Minimum Best Server RSRP Requirements – The RSRP Target should correspond to >-98dBm. o Minimum RSRQ Target - RSRQ (best venue server) >= -19dB for 100% of the venue area at 100% load at all surrounding sectors. o PDSCH SINR Target - PDSCH SINR (best venue server) >= -4dB for 95% of the venue area at 100% load at all surrounding sectors where 95% of the venue area includes the major areas of the venue where traffic is expected as well as all stairs and elevators. In addition, PDSCH SINR (best venue server) >= -6dB for remaining 5% of the venue area. o Best Server PCI – The entire Indoor Venue shall be served by the Indoor deployment. o PCI Re-use – This is not recommended. In unavoidable cases, Co-PCI signal strength difference shall be > 25db. o Transition Sectors (Good Indoor Coverage Dominance) o RSRP (best venue server) > RSRP (best macro server) + 6dB for 95% of the venue area where 95% of the venue area includes the major areas of the venue where traffic is expected as well as all stairs and elevators. o In addition, RSRP (best venue server) > RSRP (best macro server) for the remaining 5% venue area. These will ensure that indoor sectors become best servers in 100% of the indoor area. o Minimum Best Server RSRP Requirements – The RSRP Target should correspond to >-105dBm. o However, it is expected that on the higher floors of high rise buildings, the RSRP from the Macro sectors could be very high. In such cases, maintaining the Minimum Best Server RSRP Requirements as specified above may not be sufficient. In all such cases, the dominance criteria specified above will always take precedence over the RSRP Target. o The maximum number of Servers (within 5dB of best server) shall be <=3.

14 Indoor Coverage Solutions The growing demand for affordable mobile broadband connectivity is driving the development of Heterogeneous Networks (HetNets). A range of different cellular Radio Access Technologies (RATs) and Wi-Fi will all co-exist, and macro cells will be complemented by a multitude of smaller cells, such as micro and pico cells and Distributed Antenna Systems (DAS). The deployment strategies for HetNets are described in following sections. The evolution of macro base stations and outdoor small cells will ensure mobile broadband coverage and capacity for the next few years. However, as around 80% of all mobile broadband traffic is consumed by users located indoors, the challenge is to deliver fast and seamless connectivity to indoor users. There are various deployment options based on indoor coverage and capacity and these Indoor Coverage Solutions can be divided into three scenarios:1. Indoor Coverage Solution through Small Cell – Integrated LTE + Wi-Fi. 2. LTE DAS (Distributed Antennae System) Solution; 3. LTE Small Cell & Wi-Fi as separate Solution.

14.1 Small Cells Solution (Integrated LTE + Wi-Fi) To overcome the path loss from walls, windows and other obstacles, indoor deployment provides an efficient way to provide indoor coverage and capacity. This section outlines Small Cell Solution that can provide both coverage and capacity enhancement for indoor deployment. Typical Indoor Small Cell Solution Architecture Diagram can be shown as below:-

Illustration 1: Design Example – Enterprise Building (TC23)  The cluster of small cells are formed to connect the power & fiber remotely.  The Junction box will have power & fiber distribution mechanism.  It will house ACDB and fiber distribution unit. L2 switch can support up to 8 Small cells.  All small cells will be connected through AC power cable & CPRI fiber from Junction box.  This way no splicing & power connectorization required at Small cell end.

14.2 LTE Small Cell & Separate Wi-Fi Solution Typical Indoor Coverage solution with Small Cell & Separate Wi-Fi installation is shown as follows:

Illustration 2: Design Example – Shopping Mall (In-Orbit Mall, Vashi)  As shown below, very building will have multiple small cell clusters connected through junction box.  The cluster of small cells are formed to connect the power & fiber remotely.  The Junction box will have power (PDU) & L2 Switch.  L2 switch can support up to 8 Small cells.  All small cells will be connected through AC power cable & CPRI fiber from Junction box.  Saves lot of installation time on site.

14.3 DAS Solution (Distributed Antennae System) A DAS is the distribution of cellular RF to a network of antennas within a building to provide cellular coverage. The DAS distributes RF from a centralized radio source throughout the building using a network of RF cabling, splitters, couplers and antennas, fibre optic cabling and RF repeaters. The benefit of DAS comes from its ability to support multiple operators using the same system. DAS solutions can be classified as passive, active, or hybrid systems.  Passive DAS: In passive systems, the wireless signal from the RF source is distributed to the antennas for transmission, without any amplification, through a series of passive components.  Active DAS: In active DAS, the RF signal from a source is converted to a digital signal for transmission over fibre optics or cable.  Hybrid DAS: A hybrid DAS system is a combination of passive and active systems. In a hybrid DAS system, fibre optic or CAT5 cable is still used to connect the head end (master unit) to the remote units. However, passive DAS is used for distributing the RF to the antennas from the remote units.

Indoor DAS Connection Line Diagram The typical line diagram of DAS connection can be shown as follows.

The DAS system can be deployed in two different scenarios based to floor rise. For high rise floor building, power distribution becomes difficult from central place & hence the additional racks are required for power distribution.

DAS – Typical Connectivity diagram  The DAS system will be shared with other operators to provide LTE coverage.  Equipment rack will be installed next to other operators BTS in same equipment room.  Diplexers/ RF combiners will be used to inject LTE coverage through Samsung eNodeB.  A separate SMPS might require at each RRH location if distance between RACK & RRH exceeds 80 mtrs.
