1. Overview

A community is the bond connecting a city with its residents. With the rapid development of multimedia technology, modern communication technology, and computer network technology, the proliferation of IPTV, and the "triple play" integration of telecommunications networks, computer networks, and cable television networks, there is a growing demand for communication systems that provide integrated digital community services. A digital community is built with the goal of serving residents and centered on their needs. Compared with traditional communities, a digital community provides more effective management, richer culture, and more comprehensive services.

2 Analysis of Operation and Profit Models

2.1 Analysis of Traditional Property Management Company Operation and Profit Models

Traditional property management companies have two ways to generate profit: first, by charging property management fees to owners for providing basic services; second, by charging labor fees to owners for providing value-added services.

Basic services include: repair, maintenance, and upkeep of buildings and equipment; management of environmental sanitation, safety and fire protection, cleaning, and greening. Given China's current level of economic development and owners' income levels, the state generally sets a pricing or guidance price for this fee, which limits the profit margin (for example, the maximum profit margin for general residential community property management is stipulated at around 10%). Therefore, property management companies cannot obtain high profits from basic services. Their profit model also has significant limitations: narrow business thinking, few profit channels, and small profit space.

Value-added services include: milk and newspaper delivery, child pick-up and drop-off, interior decoration, electrical appliance repair, and business services. The value created by value-added services for owners lies in: providing convenience for owners, providing information to owners, and saving owners' time. Although most property management companies in China currently offer value-added service items to compensate for insufficient profits, due to limitations in their own resources, capabilities, and personnel quality, low service levels (mainly labor-intensive), and few service items, the profit space of value-added services has not yet been fully exploited by property management companies.

2.2 Profitability Analysis of the Digital Community Fiber Optic Communication Network Operation Model

Digital community construction effectively builds a communication, exchange, and business bridge between property services and neighborhood life. It makes the relationship between property service organizations and community residents, and between residents themselves, closer, making life more fulfilling and colorful. At the same time, through brand-new digital community services, it innovates the property service profit model, adheres to the principle of combining welfare services with operational services, and makes property management services more "profitable." The main profit models include the following aspects:

1. Sharing fixed telephone fees with operators

2. Sharing internet bandwidth fees with ISPs (including operators)

3. Sharing program traffic fees with IPTV providers

4. Charging channel service fees to water, electricity, and gas meter departments

5. Providing channels for elevator management departments and fire protection departments

6. Providing network windows for advertising companies (displaying advertisements on the video doorbell in users' homes; those willing to accept advertisements can be exempted from video doorbell usage fees, etc.)

7. Collection of heating fees and property management fees (via third-party payment, etc.)

8. Community e-commerce.

Virtual operators can also provide services to other departments, such as five-party intercom transmission for elevator management units, fire protection data transmission, etc. These enterprise-oriented services are all paid services, but they save a lot compared with direct investment by these enterprises.

The recent national implementation of tiered electricity pricing has adopted multiple approaches (time-of-use metering, remote real-time meter reading). Time-of-use meters still require personnel to conduct on-site spot checks, and the investment by power utilities in remote real-time meter reading is substantial. The main methods employed include power line carrier communication, GSM uplink transmission, and dual-PON structure meter reading — all of which are costly and serve a single purpose. Since fiber connectivity to households is already established, adding an electricity meter reading service as an additional user is very simple. This not only eliminates the need for meter readers to visit premises, but also enables real-time transmission of user data to the power utility operator.

Not only can electricity meters be read remotely, but water meter and gas meter data can also be transmitted over the same fiber, eliminating meter readers for these utilities as well, while adding an extra layer of security for the community. Community virtual operators can also earn three additional meter-reading service fees. There are also other services that can leverage community public construction funds, interfacing through the home media gateway to improve community management quality, supported by property management fees, and providing more household services:

1. Electronic patrol systems for security companies
2. Electronic fencing and video intrusion alarms
3. Video surveillance and audio/video intercom
4. Community streetlight control
5. Community emergency broadcasting (background music)
6. Community video bulletin boards
7. Public parking space monitoring and vacancy display signs
8. Video care for elderly residents in the community
9. Remote video care for community clinics
10. Pet monitoring for residents
