AN Insights: The Basics of Wireless Networking (FAQ)

Anywhere Networks Mesh is a patented technology of P2 Mobile Technologies Ltd. The developed technology allows for Anywhere Networks nodes to sustainable multi-hop connectivity with insignificant bandwidth degradation. It employs a simple network topology and channel allocation scheme to overcome the multi-hop throughput degradation problems.

Our wireless network based on the mesh architecture is very scalable. You can easily expand your network coverage with additional nodes to any existing Anywhere Networks mesh node to the network. While conventional mesh networks can only support a few hops before dropping to unusable throughput, our patented products support clusters of up to 64 nodes per configured network for easy maintenance and management.

resultsThe mesh architecture intrinsically provides a network with fail-over protection by forming a mesh loop likes FDDI in fibre architecture. When several Access Points (APs) are connected in a loop, every mesh node in the loop can be routed to another node by at least two different paths. When one path fails, it can route through the other path.

The resilient self-healing mechanism allows automatic switch over in seconds to an alternative path in case the normal path fails, and it supports auto-recovery.

The mesh architecture provides a high-cost saving in network redundancy as compared to conventional 1+1 redundancy, where the quantity of AP hardware and configuration complexity needs to be doubled.

The mesh architecture provides extra redundancy to the network, whilst the protocol handles the looping. Our protocol provides a seamless Layer 2 environment for network connectivity to enable the Layer 3 routing protocol for packet routing to be used within the individual mesh cluster to eliminate Layer 2 loops within the mesh.

To prevent the possibility of switches from blocking the port in the case of identifying the mesh network as a loop due to having more than one port connected with our AN nodes, a BPDU filter feature can be enabled to filter their loop detection packet and prevent the blocking to resolve this issue.

The wireless link is encrypted by WPA2 by default. And we provide AES 256 end-to-end encryption for extra security.

Roaming is a kind of client device function. A client device can choose by itself to roam from one Anywhere Access Point (AP) to another in the area covered by multiple Anywhere branded Access Points provided the configuration of APs are consistent.

Remark: Access Point functions are only available with the PTOS firmware.

As far as network planning required, coverage and throughput requirements must be considered when doing network planning including several factors, such as:

We can provide a range calculator to assist in evaluating an achievable range and throughput for a given set of environmental conditions.

The distance varies inversely with the throughput requirement and the antenna gain as with all wireless products.

Our Anywhere Networks X10, X20, and X30 Series can operate at their respective maximum throughput of 600 and 1,200 Mbps over a range of 1 km or more using their built-in antennas. When such a high throughput is not required, the range can go up to more than 24 km per linked node.

The Z100 supports around 200 meters with a Line-of-Sight access radius for both 2.4 and 5 GHz clients.

The Z500 supports a longer access range of about 400 m LOS (75° beamwidth) for 2.4 GHz clients and 500 m LOS (120° beamwidth) for 5 GHz clients.

  Anywhere Networks provides a single platform management software called the Anywhere Node Manager (A-NM). It is a user-friendly GUI software that allows for all Anywhere equipment to be configured and managed easily.

No. Anywhere Networks equipment mainly utilizes the unlicensed 5.1-5.8GHz spectrum and therefore does not require additional license fees to be used.

Anywhere Networks products use 802.11 (Wi-Fi) as our wireless protocol, it is a half-duplex protocol based on CSMA/CA (Carrier-sense multiple access with collision avoidance).

In the duplexing type, it is TDD because both uplink and downlink operate in the same frequency but there would not be any pre-defined allocation or fixed ratio in between.

As CSMA/CA is a contention-based multiple access protocol with random access which is not conflict-free like the TDMA, FDMA and CDMA, etc.

Reference of CSMA is a kind of TDD: https://en.wikipedia.org/wiki/Duplex_(telecommunications)#Time-division_duplexing

Duplex (telecommunications) – Wikipedia

But it is not the "TDD" that is generally used in the cellular network industry which also means the uplink and downlink frames have been scheduled (Superframe and subframe..) and have synchronization between the AP and clients.

The definite answer to this question is NO. The influence of a standard AP that complies with FCC regulations on public’s health is much lower than that of mobile phones and much lower than the maximum permissible exposure value as set by the ICNIRP, a non-governmental organization formally recognized by the World Health Organization (WHO).

The following are some facts about the Wi-Fi signals:
