Expanded Coverage

We’ve developed the world’s first mobile multi-hop mesh network. With the Anyfi SDK, that power is brought to your enterprise’s WiFi.


As the number of users on the Anyfi network rises, so does the coverage area of each traditional Access Point. Each user device connected to the internet through the Anyfi network effectively becomes a dynamic, mobile Access Point available to others. If an Anyfi user is not in connection range of a traditional Access Point, they automatically connect to another user in range. We call each of these range extending user connections a “hop”.

With the Anyfi SDK, the coverage area of the traditional Access Point grows exponentially depending on the number of “hops” away Anyfi users are connected. Simple geometry* shows just how massively coverage expands with Anyfi’s multi-hop technology.

With a zero-hop network, or a connection of a device to a traditional Access Point with an average range of 40m**, the coverage area is ~5,000². With a one-hop network, or two steps away from a traditional access point, the coverage area expands to ~20,000m². With a two-hop network, three steps away from a traditional access point, the coverage area expands to ~45,000m².  

With just two “hops” on the Anyfi network, the coverage range of an existing, traditional Access Point increases almost tenfold. The magic of this expanded coverage is that it does not require the complex, costly installation of new Access Points-- it happens simply with the Anyfi SDK.

Another important benefit to note is that Anyfi’s mesh technology overcomes typical topology challenges as it continually adjusts and reconstructs itself. Anyfi’s dynamic network allows for connections to take place without a direct line-of-sight with an Access Point.

Congestion Control

 

Traditional WiFi networks suffer greatly from network congestion. Anyfi networks can handle a high number of users and huge amount of traffic with three main technological advantages:

 

Dual band support (2.4GHz / 5GHz)

Many Wi-Fi systems only support the 2.4GHz band, which is overcrowded by a myriad of devices running the gamut from microwaves to Bluetooth beacons. Ordinary smartphones and computers ships with state-of-the-art networking hardware, with dual band support and a network monitoring system to detect network congestion. It has all the requirements to be a top-of-the line Access Point - so why not let it be one?

Anyfi networks support both the 2.4GHz and 5GHz bands -- minimizing crowding and wireless interference while providing greater signal reach and additional network bandwidth. With a total of 26 non-overlapping channels for transmission, dual band support is much cleaner with less interference, making it suitable for applications like video streaming which are sensitive to packet loss and delays.

 

Packet synchronization

Furthermore to combat congestion, Anyfi networks have built in packet synchronization. A major reason for congestion issues is the increasing number of packet collisions with more user connections. In Anyfi networks, instead of having users fight over time in different transmission channels, time is efficiently allocated to users via synchronized permission tickets to prevent packet loss and collisions - minimizing local congestion.

 

Dynamic bandwidth

Our software gives you complete control and flexibility to manage your bandwidth. Depending on the needs of your network, a limit can be set on the upload or download speed of each user. A limit to the usage bandwidth can also be set depending on your network configuration and needs. This dynamic bandwidth, in tandem with dual band support  and packet synchronization, ensures a manageable amount of network traffic from your users no matter the number of connections.

Automatic Upgrades

 

Traditional networks require a prohibitively costly and complex overhaul of hardware every 2-5 years to enhance performance, reliability, and security. Upgrade efforts have exponentially increasing complexity and cost with a greater number of Access Points. They usually include: site surveys; conduit and network design; installation of new conduit, wiring, switch, and access points; network equipment activation and configuration; and post installation testing. Also to be taken into account are the disruption and costs associated with the construction necessary to complete these upgrades.

Anyfi networks will significantly lessen the upgrade demand and associated upgrade costs as users organically upgrade their devices. With new releases every year, smartphone wireless capabilities grow. As users periodically replace their smartphones, the Anyfi network strengthens with even better range, speed, and security. This organic enhancing of network capability through users fundamentally decreases the enterprise’s burden of upgrades.  

State-of-the-art Security

 

Security should be of paramount importance in distributed, peer-to-peer networks. That’s why Anyfi’s mesh network has been designed for security from the beginning, not as an afterthought. Anyfi’s network guarantees the following security features:

 

Bilateral Authentication

By using a time-based OTP to encrypt the WPA2 passphrase as it is being shared, both connecting devices are required to know the same OTP, and the shared key and the algorithm that generates it. As discovering both the shared key and the precise password generation algorithm is improbably difficult, the OTP process ensures bilateral authentication in device connections.  

        

End-to-end Encryption

By requiring all network traffic to be asymmetrically encrypted between each pair of devices,  end-to-end encryption is achieved. Traffic cannot be tampered by the devices in the network.

    

Robust Layer-1 Encryption

All network traffic is encrypted via WPA2/PSK over the wireless link layer, making it virtually impossible for the attacker to access the network traffic from outside of the network.

    

System Isolation & Integrity

    Anyfi’s software bricks whenever it detects:

  • The device is rooted
  • The software has been tampered (Cyclic redundancy check fails)

  • An unidentified application is installed on the device

The above checks guarantee the software integrity of every device connected to the Anyfi network, and can act as an extra safeguard against attacks.
