An 8K video stream requires at least 150 Mbps of bandwidth, which is four times more than 4K. Applications such as live streaming, online classes, and live streaming require very low latency, typically 50 milliseconds or less. In addition, home broadband connections need to be capable of supporting multi-service concurrent scenarios. High-quality Internet has become an indispensable part of people's lives, work, and entertainment. Fiber optic cable is the most preferred transmission medium in networks for its superior bandwidth, faster speed, and enhanced reliability. Fiber to the room (FTTR), which extends fiber connectivity from the "last mile" to the "last meter", offers customers a premium full fiber connection, enabling to meet network requirements of various home applications.

Gigabit broadband connection has become to a broad consensus.  Home Broadband is moving from the entertainment center to the multifunctional center

Since the outbreak of pandemic, operators face increasing demands for the high speed of connections. Many operators around the world has released gigabit broadband services, which promise to deliver download speeds above 1 Gbps. At the same time, there is a broad consensus among global policymakers that high-speed broadband is essential to booster economic growth. EU and Asian countries governments have sets super-fast broadband targets.

The experience quality of broadband networks has become more critical than ever. High quality of entertainment contents such as such as 4K/8K, online gaming and VR/AR are gaining popularity in home. The outbreak of pandemic accelerate adoption of remote work. Smart homes devices are also gaining traction globally.  Home Broadband is moving from the entertainment center to the multifunctional center. High speed broadband is a major prerequisite for enjoyment of high quality of entertainment content, access to companies’ resources through clouds and supports a variety of smart home devices.

Fiber is a key enabler to deliver fast speed internet connections. According to IDATE, as of December 2021, there were 773 million FTTx subscribers worldwide. According to our forecasts, there should be 973 million in 2025. FTTH promises connection speeds of up to 1000 Mbps, 20 to 100 times faster than a typical cable modem or DSL connection.

Wi-Fi technology remain the preferred technology for in-door usage. Wi-Fi 6 , 802.11ax, the latest standard of Wi-Fi network, promises faster throughput speeds, better battery life, and  increased support for several high-bandwidth devices, like smart home devices.

Enhanced digital Service drive the home broadband requirements, traditional Wi-Fi Solution face 3 challenges:  Poor experience, High OAM cost, Inconsistent W-Fi coverage

As home broadband become to a multi-service center and need to support various smart home devices. Traditional Wi-Fi technology is beginning to show its age and is no longer able to meet the requirements of new digital service network. Data-heavy applications and smart devices put a strain on traditional Wi-Fi technology, and it is no longer able to handle the load. This results in poor connections, slow speeds and frequent dropouts.

Home Broadband is moving from the entertainment center to the multifunctional center, stimulating explosive growth of data traffic in operator networks and posing great challenges to existing home networks. Key problems include insufficient network bandwidth causing poor user experience, high OAM cost: and Inconsistent W-Fi coverage,

  • Poor experience: Since traditional Wi-Fi technology has not enough bandwidth to hand a number of devices, most Wi-Fi networks do not exceed 100 Mbps, compared to FTTH speeds of more than 500 Mbps and cable/Wi-Fi speeds of 100 Mbps. Many Wi-Fi users experience poor connectivity and slow speeds during peak hours. In fact, poor Wireless poor experience complaints made up 60% of Issues.
  • High OAM cost: Wi-Fi network status mainly relies on displays to passively indicate the network status. Wi-Fi networks are difficult to manage, which makes resolving connectivity issues with Wi-Fi networks difficult. Certain Wi-Fi connectivity issues may difficult to be localized and fixed. In some cases, it is necessary to contact the service provider to fix issues on-site. However, relying on on-site repairing service is usually very time-consuming and expensive.
  • Inconsistent W-Fi coverage: Most home networks function with a single Wi-Fi access point, each access point with limits coverage from dozens of meters. However, various obstacles (walls, ceilings, furniture, glasses, etc.) located between Wi-Fi devices may partially or significantly attenuate Wi-Fi signal, leading inconsistent Wi-Fi coverage in home. 55% of complaints is related to insufficient Wi-Fi coverage.

What is FTTR ?
FTTR, fiber to the room, extend fiber connection to every room to provide ubiquitous gigabit wireless access. FTTR is the next step of FTTH solution. In FTTR architecture, a FTTR main modem is connected by optical fiber to multiple edge FTTR devices placed in different locations. Both Master and slave FTTR units can provide Wi-Fi 6 access so that each corner of house can reach gigabit speed access. Mobile apps is used to facilitate the monitoring, maintenance, and management of the entire network.

FTTR for Home solution

Compared to traditional FTTH technologies, FTTR show various advantages:

  • Enhanced network speed and guaranteed in-door network coverage: : by leveraging fiber and Wi-Fi 6 connectivity, FTTR promise to delivery up to more than 1 Gbps internet speeds with roaming latency of less than 20ms. The technology also can provide sufficient bandwidth to connect up to support 16 Wi-Fi access points and 128 smart devices terminals online. Compared to traditional FTTH based Wi-Fi network with average internet speed around 100 mbps, FTTR can increase the connection speed by 90%, achieving full house Gigabit Wi-Fi coverage.
  • Intelligent planning, acceptance & maintenance: Implementation, acceptance, and maintenance of FTTR solutions can be entirely managed through a mobile application, which can be used to simulate the deployment of master and slave FTTR equipment, as well as support network topology and speed acceptance tests. Furthermore, operators can use the mobile application to get alerts, and to locate and troubleshoot abnormal problems remotely, making maintenance visits less frequent.
  • Easy installation and greener solution: fiber is easy to deploy in house because of the lightweight and small diameter of optical fiber cable. On average, it takes only 30 minutes to complete a hotspot deployment. Additionally, FTTR is also a “greener” solution, reducing energy consumption by 30% compare to cable connection, enabled by the low loss of optical fiber

FTTR redefining High Quality of Digital Home Life

FTTR technologies, combining with latest Wi-Fi 6, redefine high quality of digital home Life and enable to support multi-service concurrency scenario, paving the way for next-generation immersive life experiences.
