Can we get wifi without Ethernet? Can we make it faster?

Thanks for asking this question.

Wifi and Ethernet are two separate things.

Wifi is a physical connectivity layer. It’s like fiber optic and LAN cable. Only it’s wireless.

Ethernet is a protocol that can be implemented on wide variety of physical mediums. RJ 45 LAN cable is the most popular type of Ethernet physical layer although fiber optic Ethernet also exist.

Now one of the most common use of Ethernet is to provide internet from a router to a connected device, via a cable.

Similarly wifi provides internet connectivity with the help of a wireless channel. No cables involved.

With that cleared. Yes you can use wifi without internet. But if the wifi device has no internet from the modem, then you’ll only be able to browse services that are local to that device.

[An example of this is the wifi admin web app you are able to access even without internet. You can try this. Take out the internet cable from your WiFi device and try connecting to the admin panel. It should work without any problems. ]

Infact this is one of the basic principles of offline physical internet technology that allows you to connect to WiFi devices without needing internet. Enabling all sorts of new interactive technologies from payments to advertisement.

Can it be faster? Well wired communication is always going to be faster than wireless communication because of a dedicated physical communication channel that never has to deal with interference. Ethernet speeds for example have already reched 100 gbps. Some manufacturers also report 400gbps speed.

Where as wifi is at about 11 Gbps mark. But I think that is fast enough for practical purposes. Considering that 4k streaming requires a tiny 25 Mbps of speed.

Add to that the convenience of setting up and maintaining wireless networks and you’ve got very compelling reasons for using wifi.

What is wifi passpoint?

Vizcaíno island,Uruguay

Wifi passpoint is codified by IEEE in the standard 802.11u. This standard would make a wifi capable device interoperable among various service providers. Some of the features of 802.11 u include

1. Network discovery. Allows the client devices to discover varoius types of networks through access point advertisement. These networks can be free, public, private or paid.
2. Network discovery will be enabled by Generic Advertisement services that will allow the client devices to query for more information on an access point **before** they are connected. Today access point information is available only after device connects.
3. Generic advertisement services will be powered by Access network query protocol or AQNP which defines the mode of communication between a client and access point to discover information like roaming partners, authentication methods etc

In addition to this 802.11 provides a better quality of service on a per device basis as well as an inproved selection interface un- authenticated users to enable them to choose a wifi service of their preference.

The key strategy behind 802.11u is network data offloading. Mobile networks like 3g ,4g and 5g are good for voice and messaging services like traditional mobile networks have been. And while they have improved data access they are too costly compared to broadband and wifi.

A single network for both voice and data connectivity has also put an undue burden on cellular networks therefore nations are now embracing wifi as the universal and standard medium for data communication. For example check out Bharat wifi plan

Simple wave, an inexpensive last mile communication technology

378 fiber optic cables covering an estimated 800000 KMs around the earth transmit data at Terabit speeds. How fast is a terabit? One tera bit is 1000 gigabits. A network with a speed of one terabit per second will transfer 1000 gigabits of data in 1 second. 1 gigabit in a millisecond. A 2 hour long high definition video of 32 giga bits can be downloaded in 32 milliseconds. We take 100 milliseconds to blink an eye.

And yet fiber optic cables together with all the satellites, copper wires and other transmission mediums are only able to provide internet to less than half of the worlds population.

More than 3B people have no or marginal access to the internet. The benefits of technology, global knowledge sharing, digital financial services are all unknown in these parts of the world.

Data is costliest at the last mile. Terabit speeds resolve to a few mega bits at the level of consumer.

All of our internet achievements have been the result of decades of work. While, no doubt, it is commendable, it raises an uncomfortable question. How many more will be needed to connect the rest of the world? How many roads will need to be dug up before more homes can be connected, if that is indeed, as it appears to be, the big plan?

Perhaps more importantly what can we do with the infrastructure that is already in place? Surely these must be an alternative to this all or nothing, black and white outlook towards connectivity.

It is true that digital technology is the driver of innovation in the world today. Such has been its impact that many companies prefer to call themselves digital even when they offer a physical product. Digital banks, digital airlines, digital shops, cloud kitchen? Digital has become a symbol of high performance. On merits? Perhaps? Perhaps not? For now we are not going to argue on this point. But I hope we can all agree that it certainly seems to be the perception.

While the trend is going towards increasing the speeds, with the idea that high speed data will increase the rate of innovation, it is easy to agree that the impact of communication technology will be highest in places with no/limited connectivity.

Simple wave is a collaborative project that looks to provide alternative means of connectivity to the unconnected places in the world. Make the last mile inexpensive.

Wavelength

All Simple Wave stations must confirm to the following 3 principles

1. Technology based on open standards. Open source software for operation. Open cellular frequencies for communication. Standards which can be used by all. To minimize the setup, distribution and working costs.
2. All stations must operate in online and offline modes. Even when the network is unavailable the stations must provide core services as a part of its operation. Network independent services will be accessed by the users wirelessly in the same way they access network services.
3. Single point of access managed via a secure identity program. All Simple Wave stations will be compatible with each other. A user with access to one Simple Wave station will be able to access any Simple Wave station anywhere in the world.

Please note that the access here means access to the network. Application services may employ their own identity management and restrictions. So while a user will always be able to access Simple Wave station, the services may/may not be accessible depending upon the situation.

Waveforms

As long as simple wave collaborators and partners agree to the principles above they can use simple wave stations in any way they want.

Want to charge for internet access? Sure. Simple Wave allows you to run accounting on identities.

Want to give away free service? Simple Wave lets you do that too.

Want to deploy business specific applications? Go right ahead.

Simple Wave can be a wireless internet gateway, a voice calling service, a messaging platform. CRM, e-commerce, news feed, social network. Video game server or a movie streaming station. Simple wave can be anything you want. And maybe even more.

Phase

Simple wave is flexible enough to serve different geographical requirements.In coastal areas with direct access to fiber optic connectivity Simple Wave may be used as a feeder/backhaul for inland connectivity. Simple Wave coastal distributors may also be used offer cheaper data plans to encourage tourism.

In inlands Simple Wave is capable of dense deployments to handle peak demands. Further Simple Wave stations may also allow access to specific technologies that encourage effective administration and development of smart cities.

Simple Wave may be attached to an antenna on ground or mounted on a satellite and sent into orbit. Once more Simple Wave does not make any assumptions on how to best use it. It leaves it to the operators. As long as an operator confirms to Simple Wave guiding principles they are free to do what they want.

Amplitude

Simple wave is a collaborative project. It recognizes the importance of partners in execution of ideas. As such Simple Wave is eager to partner with

* Infrastructure Providers: Organizations that work with network equipment, Hardware manufacturers etc
* Service providers: Infrastructure is for nothing if applications don’t work on it. Simple Wave is a secure but open platform that is compatible with the services of key economic sectors such as education , retail, transport, banking and entertainment. Simple Wave partners may chose to deploy their branded services on their Simple Wave wireless machines.
* Operators. Post deployment Simple Wave will need skilled professionals for up keep and maintenance of the system. Simple Wave will create 100s of jobs and demand for skilled workers. To fulfill this requirement Simple Wave is eager to partner with premier educational institutions around the world to help inculcate this skill among future professionals.

Frequency

Simple wave is a convergent telecommunication technology that aims to promote open cellular infrastructure to decrease the associated costs in setting up of telecommunication technology and increase the rate of innovation in the world.

It is our belief that Simple Wave will multiply the effect of other service industries rapidly by giving them a wider reach to an audience that would otherwise not be able to have access to their products.

Simple wave is a cross functional collaborative project. We are eager to work with people in different industries. Technology, manufacturing, hospitality, education, finance, retail , arts,science,government etc.

Do different wifi devices have slower/faster WiFi receivers?

Thank you for asking this question.

Yes it is true. Different devices may have different speeds according to the kind of their wifi receivers.

Wifi speeds have evolved in generations. This is why when you see the wifi specifications on the device it will be listed something like this

802.11 a/b/g/n/ac/ax

The letters a,b,g,n,ac,ax denote different wifi standards that the device can work with.

So if this hypothetical device connects to a router with 802.11n capability it will get speeds according to 802.11n standard and so on.

The good thing here is that most wifi devices ,both base station and client, are backwards compatible so they work across a variety of standards. In this respect the members of wifi alliance and it’s partners have done a terrific job! Otherwise industry is rife with examples of backward incompatibility. Thankully wifi avoided this route.

Finally as an example take a look at Qualcomm snap dragon 855 mobile platform that powers the recent one plus 7 mobile among many others phones.

Snapdragon™ 855 Plus | Best Mobile Processor for Gaming

Now if you go to the wifi section you’ll see that it has support for following standards

802.11ad, 802.11ay, 802.11ax-ready, 802.11ac Wave 2, 802.11a/b/g, 802.11n

Which means that it can be used with a wifi router supporting any one of these standards. Accodingly it will get speed that corresponds to that standard.

So when you upgrade your router to new standard all your client devices automatically benefit.

Workrock wireless’ wifi beacons help in digitizing key economic sectors of banking, transportation, tourism, retail and education.

ASUS XG-C100C 10 Gigabit PCIe Network adapter

#ethernet #fiber #internet

XG-C100C is a low cost 10 Gigabit network interface card by Asus. The card is based Aquatia AQC107 chip [1]. While the highest speeds (10 Gigabit)are attainable with CAT 6a cables the card is also compatible with 5/2.5/1Gbps and 100Mbps standards on Cat 5. It is flexible enough to be used in a variety of service categories.

XG-C100C comes built in with 802.1 p support that provides Quality of service on the hardware level with implementation of 8 traffic classes. Quality of service controls mean that the user can prioritize traffic speed going through each physical/virtual port.

QOS support is provided by the operating system. eg vconfig [2] in linux helps you create VLANs on which you can assign traffic speed classes.

While the application of QOS is specific to use case it is good to know that XG-C100C helps you create scenarios in which you can prioritize certain kinds of traffic, like applications that consume high bandwitdh due to streaming games, movies etc running on their own virtual interface.

Aquantia supports linux natively and they have contributed their drivers to the linux source code [3]. So using an Aquantia card and hence by extension XG-C100C should be a plug and play experience for most linux users. This makes them especially attractive from a service deployment point of view. Using linux based system for internet access means no associated licencing cost as compared to proprietary platforms.

Besides that, the chip supports a wide variety of protocols most of which are to be expected from an ethernet card but some features like Wake on LAN are good addition to the standard stack. You can check out the full list on their product brief [1].

*Gadget Blues’ review of XG C100C on youtube is quite thorough so do check it out*

XG-C100C chips can be used to create wireless internet distribution hubs for a small offices with about 100 employees or a 6 floor multifamily residence housing 50 apartments.

The chip is powerful enough to serve multiple concurrent users while maintaining an appreciable quality of service at hardware and application level.

For redundancy and better bandwidth provision multiple systems embedding these chips may be used. Although on motherboards with multiple PCIe slots several of these chips may be combined to build a single access point for multiple users.

[A system designer should take note of the bandwidth requirements and provision adequate main memory for DMA access by the cards. ]

Whether you go for a consolidated access point or a distributed access point architecture depends upon the service requirements. In a dense location where people using the network would be close to each other, like in an office, it would make more sense to go with a consolidated architecture and save costs. In a sparse environment distributed architecture becomes a necessity.

A middle ground may be chosen for keeping the costs low while at the same time providing a redundant network access by setting up two access points in tandem on different devices and using cheap range extenders to increase the network coverage.

Since XG-C100C works on an electrical Rj45 ethernet port it can also be used as a part of a high capacity Optical Network Unit. A small form factor plug transceiver would convert optical connections into electrical and the ethernet port could be used to distribute the network either over wired RJ45 cables to the end users or wirelessly over a high speed external wifi network. This comes in handy at locations where fiber optic connectivity is available. The fact that the card is more than capable of handling high speed fiber optic connection makes it an obvious choice in these scenarios.

**Final thoughts**
XG C100C is a low cost, high performance feature rich network card that makes it a good fit for both home and enterprise usage. A good driver support in Linux means that XG C100C machines can be used in service deployments. Although a single RJ45 port is a bit of a letdown XG C1OOC is still an impressive piece of equipment for providing high speed LAN or internet connection.

Workrock Wireless builds gigabit wireless distribution systems for internet service providers. Our technology can help you serve customers in residential and commercial buildings as well create open wifi access points at airports restaurants and railway stations. Our devices are compatible with both fiber optic and well as traditional copper lines.*

Workstations for support industries

Wokrock’s portable workstations transform a plain desk like the one shown in this photo into a cornerstone of enterprise.

Digital technologies have allowed enterprises around the world to outsource their business operations. To their own benefit, of reduced operational cost, and to the benefit of developing nations, of increasing the employment opportunity for their citizens. Business Process Outsourcing has been one of the big wins of globalization.

Offshore IT development, customer support, marketing, sales, accounting all sorts of activities are being performed outside of headquarters. Big industries need support not only to grow but also to simply keep moving. Take any industry as example.

In travel and hospitality managers are inundated with requests for reservations, cancellations, changes in schedule, organizing meetings managing staff. With so many moving parts and so many people to handle here in lies an opportunity for a customer support specialist to act as an intermediary between the staff and the customer. Clear the backlog of pending support tickets and leave the office staff only with the issues that require their specific knowledge.

In ecommerce as the volume of sales increases customers need before and after sale services. Its unlikely that the entire stack of issues can be cleared by in house staff. Once more a talented customer service representative can ease the support burden on the office by handling common, recurring issues. And maybe even advise clients to optimize their process after gaining sufficient experience.

Telecommunications and Banking are other industries where customer education and support is severely lacking. A well trained customer support operative can guide a prospect in making best financial decisions, choosing the best data plan for their requirement and represent their partners online.

These examples just skim the surface of industries that need support. There are a whole lot of business who are unable to communicate effectively with prospects due to lack of skill in managing technology.

How to start?

To start a customer support business today what you need is domain knowledge. Have you no knowledge in any specific business domain? Worry not. Knowledge can be gained not only by first hand experience but also developed with research. For most businesses have a website these days. And while the information may be presented in a somewhat dense and obtuse manner, a dedicated professional can meticulously dig out the relevant bits of data regarding product and services on offer within a few hours of research. With distilled knowledge all that remains to be done is to help other prospects understand offerings so that they can make the best decision.

Customer support industries are the easiest way for you to export your services globally. If not to a large enterprise then maybe to an understaffed mid sized business. If not to a multinational financial institution then to a small community bank. If not to a global telecommunications giant then quite possibly to a small wireless internet service provider. The opportunities are endless for people who want to work.

And with the social media the opportunities have only multiplied. No longer you have to sit back and wait for mails to arrive in your inbox. You can be proactive in disbursing the information. Building a marketing channel for your partners so that not only do you help existing customers by creating a knowledge base, but bring in more revenue for your clients.

In travel and hospitality this may mean more bookings, in retail this may mean more product sales, in services this may mean more contracts. But all businesses work the same way. Learn one industry well and you learn all of them.

All you need to start your own customer support business then, besides domain knowledge, is an internet connection at home or in a public place like library and a computer. Even a mobile phone would do if you’re always on the move.

Internet is cheap knowledge is free. So what are you waiting for?

Workrock’s portable workstations provide the digital technology foundation needed to set up a modern customer support center.

Effective network bandwidth and streams

In wireless communication spatial streams are meant for single devices. Wifi client devices receive from and transmit to multiple antennas but they can still only do it one at a time.

That is the parlellism that spatial streams introduce is a single device parlellism

The transmitter will break up one large data stream into multiple smaller streams which the device will assemble into a single stream once more.

This kind multiple input multiple output technology is called SU-MIMO where SU stands for single user.

In practical world, all available bandwidth is rarely distributed by a single device. Consider how many telephone towers we have to distribute the mobile signal.We have multiple devices servicing different parts of area.

So that a single network with its collection of access points is able to serve multiple users simultaneously.

Now, and this is the important part, while the devices still use channel sequentially multiple access points mean that there are multiple queues of devices.

This technique is the foundation for MU-MIMO which makes a single network capable of serving multiple users at once using streams.

MU-MIMO may also be applied to a single device which turns a half duplex wireless communication into full duplex. In simple words this means multiple devices can communicate with a single station at the same time without having to wait in a queue.

Improvements in Wireless services not only mean a greater throughput to a single device but also total in crease in network capacity.

It is better to have 4 devices at 300mbps than a single device with 1.2gbps.

The wireless speeds available at the moment are capable of exhausting the most demanding data applications like 4k streaming. Where we lack is in distribution of this speed equally among devices.

Workrock wireless provides wifi nano networks that can be used for immediate hassle free connectivity. Our wireless beacons can be used at airports, shopping malls and banks for network defined software services like marketing, e-commerce, social networking etc

What is wifi direct?

Wifi direct is a wireless communication standard that allows you to establish a P2P connection over wifi. Just like you do over Bluetooth.

The advantage of wifi direct is reduced setup time. So the client devices can get on with consuming the wireless services immediately without having to go through the ritual of establishing connectivity.

For wifi direct to work only one device needs to be compatible with the standard. Behind the scenes a technology known as soft access point handles the setup. For the user, connectivity is as simple as a tap on the screen.

Workrock wireless provides wifi beacons that allow for immediate, hassle free connectivity with client devices. Our beacons with their gigabit wireless speeds can be used in ecommerce, marketing, internet access and network defined software services like messaging, social networks, education,travel portals and digital banking. Our technology is compatible with all smart phones and allows multiple client devices to be connected simultaneously as long as they are in the range of the network.

What is the difference between wps and wpa in wifi?

WPS stands for wifi protected setup. wifi devices usually require a bit of tweaking before they can be set up. You need to configure an SSID, take care of the security of the network by assigning it a password and then you need to connect it with your client, where the steps are repeated. Although this method is usually required only once still it was considered to be a bit of a hassle.

Comparatively in Bluetooth, for example, you simply turn on the BT device and it can be paired in a quite straightforward manner with other BT compatible devices.

WPS was wifi’s attempt to make setup of a new network easy and secure. With a WPS device you can connect to a network by simply pushing a WPS button or by entering a PIN code. All the hassle of setting up an SSID and passphrase is taken care of for you automatically by the device itself. Note that while as a user you don’t have to create an SSID/password they are still generated. Only its all automatic.

It is also considered insecure by most security researchers [1] . While the PIN method of accessing the network is considered to be susceptible to brute force attacks the security of push button depends upon whether the device is itself secure.

One of the greatest disadvantages of WPS is that all of the devices, both client and AP must be WPS compatible. In other words before you set up a WPS you have to check whether your AP supports it. Then you have to check whether you client devices like mobile phone supports it. And then you have to figure out a plan for all the unsupported devices. Frankly this is even more of a hassle than the one WPS seeks to eliminate.

Nevertheless WPS still offers some significant advantages. Considering that WIFI is a short range radio device, it means the range of the network is limited to a very small area. Meaning having access to a network is not trivial for an outsider . As such the convenience of a quick set up might in some cases be useful. Especially where no sensitive data is exchanged on the network. Or when the network has to provide access to public read only content but wants to limit its access to people who have the PIN.

WPA stands for wireless protected access. WPA had many vulnerabilities, and it was supposed to only be an interim standard, so it was superseded for good by WPA 2. WPA 2 itself has many variants.

WPA 2 psk is a variant of WPA where the key is shared between connected devices. PSK here stands for pre shared key. WPA 2 psk is designed for a small office and home network where all the people who’ll be connecting to wifi can be trusted. Although WPA 2 is secure sharing the password with other people means that any one who has access to it can snoop on the network. For a home use case a WPA-2 psk is secure enough. And you can always change the password if you have any doubts that some one else is using it.

That is why for environments where security is essential WPA2 Enterprise protocol is used, in which each participant has a different password and can’t have any access to the network as a whole. It effectively isolates the network per user.

What are google messages and how do they fit into RCS?

SMS based texting is simple and reliable but its out of date. These days messaging apps are expected to be able to send photos videos and even voice messages. This is what RCS or Rich communication services aim to do for SMS technology by upgrading it at the carrier level. Essentially transforming a simple text based service into a full blown multimedia sharing application and social network.

Google messages are a part of Google’s Rich Communication Services platform. Google messages can use Wifi and data services, if chat is enabled.

However chat feature is only available in countries where carriers support RCS. Meanwhile in UK and France Google has launched it’s own RCS.

And therefore only the users in those countries will be able to opt in to RCS chat services on google messaging app, using wifi and data plan to send messages,presence data, photos and files.

One of the big challenges faced by RCS is inadequate encryption of data. The messages are only encrypted in transit rather than end to end as they should be in any application that values privacy.

While RCS is yet to make an impact on the world of messaging , mobile carriers and network operators have succeed in agreeing on a standard that can help evolve core messaging services.

Workrock Wireless provides XMPP based messaging service equipment to network operators. Our devices are wireless , operate on gigabit speed and can be deployed without any disruption to existing services.

In addition to supporting all of RCS specs including presence, contact lists, voice and video, multiparty chat, machine to machine communication, content syndication we also provide support for PCI DSS requirements 4.1,4.2,4.3.

Our wireless messaging equipment can be used in online game streaming, financial transactions, automated notifications and general communication. Being platform independant our technology works everywhere. On desktop, mobile, kiosks. In a browser or in an app.
