RF system for distribution of over the air content for in-building applications

Abstract

A system is described for distributing over the air (OTA) channels within buildings and homes. The system can implement one or more active multi-mode antennas for improved performance and reliability. The system can be configured as a mesh network where multiple nodes are distributed to improve the probability of channel capture across the VHF and UHF frequencies used for over the air TV distribution. A node consists of a beam steering antenna that operates at the VHF and UHF frequencies for TV signal reception, a receiver and demodulation circuit, a transcoder to convert the received information for re-distribution, and a transceiver capable of operation at a secondary frequency band for use in re-distributing the information to communication devices in proximity of the node. The secondary frequency band can be the common WLAN (Wireless Local Area Network) system such as Wi-Fi, with the Wi-Fi transceiver also containing beam steering antennas for improved in-building propagation of the re-distributed information.

Description

BACKGROUND

Field of the Invention

This invention relates to the field of wireless communication; and more particularly, to a radio frequency distribution system employing a reconfigurable mesh network to distribute over the air channels within buildings and homes.

Description of the Related Art

Television (TV) signals transmitted at very high frequency (VHF) and ultra-high frequency (UHF) have been available for reception by the general public for many years. These VHF and UHF signals are generally transmitted over the air by way of local transmitters and antennas in cities and communities. Historically, over the air transmission was the only method for delivery of channel information to homes. The typical over the air TV reception for homes and offices in a city typically consisted of a television antenna, often placed on a rooftop of a home or building and further connected to a television using a transmission line such as a coaxial cable. These conventional type antennas were capable of receiving VHF and UHF signals, with an efficient antenna for this application being on the order of 1 or 2 meter in length or extent. More recently, the TV channels can be delivered via cable distribution systems and satellite based systems. There are two main differences between the over the air transmission method and the cable and satellite systems: cost of service and quality of service.

The over the air TV signals can be received by users in the vicinity of the TV transmission tower, with the transmission tower containing a high power transmitter and antenna. As the users are located further from the transmission tower a lower strength signal will be received resulting in a lower quality video and audio content. Hills, buildings, and other obstructions between the transmission tower and the homes trying to receive the TV signals will also degrade the strength of the TV signals, resulting in a lower quality channel after reception, or in the extreme case, the inability to receive the channel. Antennas used to receive the TV signals at homes perform better when positioned outdoors and high above the home, typically 20 to 30 feet above ground level. Unfortunately many customers cannot use outdoor antennas, with a large number of the customers living in apartment buildings where there is no access to the roof for antenna installation. Single family home owners who do have access to the roof are sometimes not allowed to place antennas on the roof due to home owner association restrictions.

An antenna can be placed inside the home, but the ability to receive the signals is degraded due to the reduced height of the antenna and the obstruction created by the walls of the home. The signal inside rooms in the home will also have significant variation in amplitude due to reflections off of walls, furniture, and even the people living in the home. The problems described here with reliably receiving TV signals over the air is due to the fact that these are radiated signals which can be disturbed and degraded by the propagation channel.

The cable distribution method is a more reliable method of delivering TV channels to consumers since the channel information is brought into the home on a shielded coaxial cable which provides steady, undisturbed signal strength. The satellite based distribution system tends to be more reliable than over the air method even though the satellite system also relies on radiated signals. The satellite system is a more reliable communication link because the transmitted signal is radiating down from a satellite, with this signal less affected by hills, buildings, and other features. As long as the receive antenna for satellite reception has line of sight to the satellite the signal will be received at a near constant signal strength.

There are also cost differences between these TV channel delivery methods. Over the air TV reception of local television channels is free to the public in most countries except for the cost of the receive antenna used for reception of the signals. Both cable distribution systems and satellite based systems charge a monthly fee for delivery of the content, and this monthly fee can be over $50 or $100 depending on the number of channels requested by the consumer. The cable distribution companies and satellite providers need to financially compensate the local TV stations for the right to re-distribute the channels on their respective systems, with this cost increase typically passed on to the consumer. The consumer has an alternative to paying for cable or satellite TV service in that they can use the internet to stream TV shows and other content that is currently being distributed by the cable and satellite providers. As long as the consumer has an internet connection in the home, then content available on the internet can be streamed to the TV for viewing. Unfortunately the local TV channels which contain local news, sports, and other content are generally not available for viewing through online streaming. A reliable method of receiving over the air TV channels in parallel with streaming content over the internet would be desirable for both the consumers and cable and satellite distribution companies.

Complicating over the air television further is the need to provide TV to several devices spread throughout the home. A typical family might have one to three TVs in the home and as well as several smartphones and tablet or laptops which can be used for viewing content. A good TV distribution plan will provide a method for enabling multiple devices throughout a home, with several of these devices being mobile, to access TV channels.

DESCRIPTION OF THE INVENTION

A wireless local area network (WLAN) can be used to assist in the delivery of the TV channels throughout the home. WLAN has been adopted across homes and businesses in most regions of the world, with a large number of client devices such as smartphones, laptops, and Tablets capable of WLAN reception. More recently WLAN has been adopted for high throughput applications such as video streaming for in-building applications. These types of systems also require good performance from the RF radio and antenna system to ensure quality operation, and these systems increase the number of WLAN systems and RF signaling encountered in businesses, apartment buildings, and neighborhoods. The requirement for increased data rates to support a larger number of users and video applications has been met by a move toward higher orders of modulation in the transmitted signal as well as higher orders of multiple input multiple output (MIMO). These improvements in modulation technique place a requirement on improved signal to noise ratio (SNR) or signal to interference plus noise ratio (SINR) levels. Additionally, better control of the radiated field from the antenna system associated with the access point will be required to provide better communication link quality for an antenna system tasked to provide higher throughput and a more reliable link.

Another technique that can be used to improve streaming of TV content throughout the home is mesh networks. Implementation of mesh network techniques provides a method for improving communication link performance and reliability for networks. A mesh network is a network topology in which each node relays data for the network. All mesh nodes or a subset of nodes cooperate in the distribution of data in the network. A mesh network can provide improved reliability and offers redundant links for the portions comprising the network. When one node can no longer operate, the rest of the nodes can still communicate with each other, directly or through one or more intermediate nodes. Wireless mesh networks can self-form and self-heal, with the self-healing feature providing a dynamic method of compensating for faulty devices in a network. Mesh networks can relay messages using either a flooding technique or a routing technique, depending on the protocol and intended application of the communication network. A mesh network can be used to provide more reliable communication links between nodes in a network, but like a non-mesh network, the communication links are dependent on the performance of the antenna systems on each side of the communication link. Passive antennas, which are typically used in commercial communication systems have fixed radiation patterns and fixed polarization states. What is needed is a method of dynamically adjusting the radiation characteristics of the antennas used at the nodes to provide the capability of compensating for movement of one or both nodes as well as compensate for changes in the propagation channel such as obstructions caused by objects or personnel.

Commonly owned U.S. Pat. Nos. 9,240,634; 8,648,755; 8,362,962; and 7,911,402 each describe a multi-mode antenna and beam steering technique wherein a single antenna is capable of generating multiple radiation pattern modes. This is effectuated with the use of offset parasitic elements that alter the current distribution on the driven antenna as the reactive load on the parasitic is varied. This beam steering technique where multiple modes are generated is a modal antenna technique, and an antenna configured to alter radiating modes in this fashion will be referred to here as a “modal antenna” or “multi-mode antenna”. This antenna architecture solves the problem associated with a lack of volume in mobile devices and small commercial communication devices to accommodate antenna arrays needed to implement more traditional beam steering hardware.

Now, described herein is an RF distribution system where VHF and UHF TV channels are received using a beam steering antenna. The channels (signals) are then demodulated, transcoded, and re-broadcast throughout a region such as a home at Wi-Fi frequencies, with the Wi-Fi antenna system also configured as a beam steering system for improved communication link performance.

The entire system may configured as a single packaged assembly for easy installation; however, in the alternative one or more portions of the system can be separated out into modular sub components.

Additional VHF/UHF beam steering antennas can be positioned throughout the region and used in a mesh network to improve signal reception performance, receiving VHF/UHF signals and re-transmitting to other antennas using Wi-Fi frequencies.

System metrics such as signal to noise ratio (SNR), signal to interference and noise ratio (SINR), and receive signal sensitivity indicator (RSSI) are used at both VHF/UHF frequencies and Wi-Fi frequencies to monitor and to adjust adaptive antenna system characteristics to optimize mesh performance.

In one embodiment of the present invention, as shown in FIG. 7, an RF distribution system is comprised of a beam steering antenna system designed for VHF/UHF reception, a receiver/tuner circuit, a demodulation circuit, a transcoding circuit alter the data format, a Wi-Fi radio, and a beam steering antenna system designed for Wi-Fi frequencies. TV channels broadcast at VHF/UHF frequencies are received by the VHF/UHF beam steering antenna and receiver, demodulated, then transcoded to alter the format of the data, and transmitted by the Wi-Fi radio using the Wi-Fi beam steering antenna system. The beam steering antenna systems used at VHF/UHF and Wi-Fi can be adaptive antenna systems with these adaptive antenna systems defined as an antenna capable of generating multiple radiation modes. Each radiation mode of the adaptive antenna system has a radiation pattern associated with it, with these radiation patterns varying between the modes in terms of radiation pattern shape and/or polarization properties. A candidate antenna for the adaptive antenna is a Modal antenna, with the Modal antenna being capable of generating multiple radiation patterns from a single port antenna. An algorithm is resident in a computer in the RF distribution system with this algorithm tasked to control the radiation modes of the adaptive antenna systems used at VHF/UHF and Wi-Fi frequencies. The algorithm implemented with each adaptive antenna provides the capability of surveying a channel quality indicator (CQI) metric such as SINR (Signal to Interference and Noise Ratio), RSSI (Receive Signal Sensitivity Indicator), MCS (Modulation Coding Scheme), or similar metric obtained from the baseband processor of the communication system to provide the capability to sample radiation patterns and make a decision in regards to operating on the optimal radiation pattern or mode based on the CQI for the communication link. The use of this RF distribution system will result in improved received signal quality of the VHF/UHF frequencies and improved received signal quality of the Wi-Fi signals throughout the region defined for signal distribution. An additional performance benefit is derived from the ability to place this RF distribution system at an optimal location within the home or region to service to receive VHF/UHF over the air signals. The Wi-Fi link provides the ability to optimize placement of the RF distribution system as well as a means to distribute the TV channel information over Wi-Fi frequencies to a wide variety of mobile and fixed devices and TVs within the desired service region.

In another embodiment of the present invention a second RF distribution system as previously described is placed within the home or region to service and this second system is used in a similar manner to receive VHF/UHF TV channels and transmit this information throughout the service area using Wi-Fi frequencies. This second RF distribution system is used with the first RF distribution system to form a mesh network, with these two systems working in conjunction to receive as many VHF/UHF channels as possible and to improve Wi-Fi transmission coverage in the desired service region. The first RF distribution system takes the role of “Master” node in a “Master/Slave” configuration and serves as a network controller for the two RF distribution systems. The second RF distribution system receives VHF/UHF channels and transmit the channel information via Wi-Fi to the first RF distribution system. The first RF distribution system determines which VHF/UHF channels are required from the second RF distribution system for Wi-Fi transmission. The first RF distribution system transmits all channel information over Wi-Fi to the devices in the service region.

In another embodiment of the present invention the second distribution system transmits TV channel information at Wi-Fi to the service region, with these Wi-Fi transmissions coordinated with the first RF distribution system in terms of VHF/UHF channels to transmit and which Wi-Fi channel to use for transmission.

In another embodiment of the present invention three or more RF distribution systems can be used in a mesh configuration in the home or service region to improve VHF/UHF signal reception and/or Wi-Fi transmission quality. The first RF distribution system takes the role of “Master node” and controls the other nodes in the mesh. The RF distribution system that receives the best VHF/UHF signal at a specific channel is designated to receive that channel and to transmit this channel via Wi-Fi to the Master node. The master node transmits all TV channel information via Wi-Fi throughout the home or service area.

In another embodiment of the present invention the additional multiple nodes formed by RF distribution systems transmit TV channel information at Wi-Fi to the service region, with these Wi-Fi transmissions coordinated with the Master node in terms of VHF/UHF channels to transmit and which Wi-Fi channel to use for transmission. The Wi-Fi radios in the additional nodes act as repeaters at Wi-Fi to improve quality of reception of the Wi-Fi signals throughout the service area.

In another embodiment of the present invention a software application is used to assess information from an RF distribution system to determine if the system is positioned or placed at an optimal location for VHF/UHF signal reception. The software application can be loaded and used on a computer, the processor in a mobile device such as a cellphone, smartphone, or Tablet, or fixed processor. The quality of reception of VHF/UHF signals by the RF distribution system under assessment is sent to the computer or device that contains the software application via Wi-Fi signals. The RF distribution system can be moved to various locations and positioned in various orientations and the number and quality of channels can be tracked and compared to determine optimal RF distribution system placement. When multiple RF distribution systems are used as nodes in a mesh network the application software can obtain VHF/UHF channel number and quality from the Master node and the various nodes can be optimized in terms of orientation and placement.

In another embodiment of the present invention one or multiple nodes in a mesh network configured with RF distribution systems can contain fixed beam or passive antennas on either the VHF/UHF portion, the Wi-Fi portion, or both portions of the overall system. The fixed radiation pattern antenna allows for a reduced system cost at the expense of performance.

In another embodiment of the present invention, a communication protocol other than Wi-Fi can be used to transmit the VHF/UHF channel information throughout the home or service area.

In another embodiment of the present invention, a communication protocol other than VHF/UHF TV channel information can be received and then transmitted using Wi-Fi frequencies throughout the home or service area.

In another embodiment of the present invention, a communication protocol other than VHF/UHF TV channel information can be received and then transmitted using a protocol other than Wi-Fi throughout the home or service area.
