System and method for creating cheap efficient high-speed home networks.
First Claim
1. A system of improved computer networking comprising at least one of:
- a. An Ethernet over coax system, comprising at least one Coax cable, at least two Ethernet sockets, Filters coupled to each Ethernet socket for shifting up the normal Ethernet frequency in order to send it as data over the Coax and shifting down data received over the coax back into the normal Ethernet frequency, and at least one of;
1. Means for using more than one frequency channel for carrying frequency-shifted Ethernet communications over the Coax, and 2. A home computer network based on Ethernet over Coax, wherein more than one computer shares a modem or optical end unit other internet connection device which is in the apartment though said network;
b. A computer network wherein the normally unused 2 wires in phone cables within houses and/or offices are used for creating cheap home computer networks in existing houses and/or offices;
c. A system of networking wherein at least in installations in new buildings and/or new installations in existing buildings a street switchboard is connected to buildings and/or to the apartments or houses with one or more coax cables and/or one or more Ethernet cables instead of normal phone line cables, and/or phone cables and/or coax cables and/or Ethernet cables are used which come with an additional one or more optic fibers combined in the same cable, and/or through wireless communication which is transferred on existing coax cable, and/or by HPNA or similar technologies over phone line.

Abstract
Broadband connections of end users to the Internet are becoming more and more common today, and the most common types of these fast connections are ADSL and Cable modems. These connections are typically still very slow compared to the speeds that are expected in the next few years and typically also highly asymmetric and allow typically 750-2000 Kbit per second (most typically 1500 Kbit) for the downlink and typically for example 96 Kbit or 128 Kbit per second for the uplink (although standard ADSL can in principle support up to 8 Mbit per second download speed and up to 800 Kbit per second upload speed), based on the assumption that most users download much more data than they upload. However, for many users these limitations are highly undesirable, and these are for example home users or small businesses or organizations who want to use the connection also for example for VOIP (voice over IP) communications and/or Video-over IP communications and/or conferences and/or for example running web servers and/or for example various p2p applications, and in fact the low uplink also many times slows down the downlink due to the overhead needed for dealing with relatively small packets, so that any additional uplink by the user can severely limit the real downlink that can be achieved below the downlink bandwidth which the user is paying for. Actually ADSL is beginning to be replaced in some places by VDSL where the distance to the nearest street switchboard is about 1.2 Kilometers or less, which in principle allows up to 52 Mbit per second Download speed and up to 16 Mbit per Second Upload speed. However, these modems are expensive and are only slowly entering the market and only in a few countries. On the other hand there is no need to upgrade typical cable modems for enabling faster speeds, such as for example 20 Mbit downlink and 2 Mbit uplink, as is offered for example in France, when the ISPs start offering such speeds—since the typical common cable modem is already capable of such speeds. The present invention enables an improved Ethernet-over-coax solution which enables using one or a few very high speed modems, each for multiple users or apartments, preferably in combination with very cheap and very fast home networks (offering preferably at least up to 100 Mbit per second for each computer, preferably at full duplex), preferably based on the Cable TV coax cables, so that multiple computers can share the same internet connection for example in the same apartment and/or communicate between themselves. This preferably includes using a different frequency for the Ethernet-over coax channel for each computer in the apartment. Also shown are for example improved home networks using the second set of normally unused 2 phone wires and for example some improvement in HPNA networks, such as for example using HPNA also to connect between the street switchboard and the home or office instead of having to use also for example an ADSL or VDSL modem.

12. A system of accessing the Internet through cable modems with download bandwidth per computer of more than 50 Mbps wherein the ISP supplies individual apartments with a Cable modem which uses a bandwidth channel of at least 10 MHz instead of the normal 6 MHz, and in addition this modem can be remotely configured by the ISP for various frequency bands over the 860 MHz and/or in other frequencies, so that as more bandwidth is needed the ISP can divide the typical 150-250 users who share the same line into subgroups, so that the modems in each sub-group use a different band.

18. A system of networking wherein at least when the street switchboard is close enough to the house or office, at least when the Internet connection is supplied by the phone company, HPNA connection is used also between the house and the street switchboard instead of having to use also an ADSL or VDSL modem.
