Optical network for fast internet and smart HD TV in your community with a total cost below the $ 4000? It’s coming!
Services: Internet-222Mbps symmetrically and clever internet HD TV with recording and reflux by watching
Typical of the agglomeration with the new housing is the ideal solution for choosing G EPON technology. The density and the number of connected end-customers choose this cheaper uploaded wodaplug technology (due to the capabilities of the services provided and obtained speeds) with a shared optical cable.The great advantage is also a simple implementation and configuration of the Ethernet standard. And input costs? “Overall, including a 1 GB connection and distribution nepřesáhli when using wodaplug optical technology lines 100 USD”, says co-owner of the company that provides complete services in the field of data transmission and Patrik Prešl RETE applications.
And how to do it, then?
As an input for the municipality article was established in-band microwave link 80 GHz 1 Gb full duplex, for whose location was voted the highest building in the village school. Network and service management with the old router preconfigured ISP services (HD TV, internet, etc. According to local requirements) and then followed by the EPON OLT Wodaplug WDS1U4PGE control unit, which has a dimension of 1U rack placement. 4 Gigabit EPON ports wodaplug WDS5441H-C (H) 3AL with range up to 20 km (in real terms) are more than adequate to cover all potential customers, in case of increase can be used 8-i port license unit. On each port can connect up to 64 end units, but in order to ensure sufficient speed for the final user to connect up to 32 is optimal the units on a single port.
For the OLT unit therefore follows the optical tub with PLC spliters that divide a shared optical fiber into each of the branches toward the end customers. As appropriate, we chose the first 4:1 PLC spliterem, and then the next PLC spliter 8:1 (that is, 4 * 8 = 32 end ONU for end-customers). The school, therefore, are based on 4 optical lines which are then further divided towards the houses of customers.
For the distribution network after the village we chose a combination of outdoor optical cable (16 threads in one) with the use of curtains on public lighting (non-standard, but cheap and perfect solutions for wiring in the already finished zones without having to interfere with the structures of communities) and in the new buildings then save the optical cable to the sidewalks. Optical fiber that we used for outdoor divorce, has 16 fibers in a single cable, there is also provision for a further increase in the number of trailing units. After adding an additional SFP module into the port PON OLT unit, simply use the same cable and its not yet unused thread come to life and will bring the signal to other stores. It will therefore be possible realistically without further significant cost to connect a total of 4 * 32 = 128 users (4 PON ports and 32 ONU on each).
Similar to how we have chosen and for the realization of all-optical networks in the other, a larger satellite town, where we already had customers connected over Wi-Fi. The transition from Wi-Fi to the optical network with elements of wodaplug was due to previous experience very simple, unpretentious, the costs outweighed the disappearance having paid reliably (e.g. outreach), and customers appreciate noticeable improvement services and stability. For a denser buildings, we chose the distribution of splitery in the 8:1 ratio running two in succession, the signal to us that once again came out optimally.
In General
Optical network behaves transparently as a smart switch, you can configure the VLANs are for individual ports end the. The configuration is simple thanks to the front of the programmed cutter path diameter of templates such as. previous installations. clone installation (when the 4 and 8 port OLT unit wodaplug offers template management!), so the newly connected the downloaded configuration according to the preset templates (provisioning ). Configuration of the OLT unit via the included configuration software EMS – central management (based on SNMP and mySQL and other needs to install SW on PC), or by using telnet and the CLI (command line interface). They also support protocol SNMP (mibs).
The competitive advantages of hardware
EPON OLT unit WDS1U4PGE are fitted with branded chipset Cortina CS8032, their performance and signal level is thus at a very high level and ensure wide coverage for your network stable signal and a varied range of deployable technology already proven services in practical deployments. For example, heat resistance was also tested in real conditions at temperatures much over 40C.
The great advantage is also DUAL POWER supply, that is, the units have two redundant sources!

Atention – not use VLAN 1 and 3, VLAN 3 is used for internal communication of Cortina chipset and is prohibited! VLAN1 use for management only!
Example of CLI configuration of an OLT unit Wodaplug for this scenario using templates – provisioning
1. Config the OLT uplink port vlan:
epon# swport ge1
epon(GE-1)# vlan
epon(GE-1)# vlan add 7 tag
epon(GE-1)# vlan add 33 tag
2. Config the OLT pon port vlan:
epon# swport ge5
epon(GE-5)# vlan add 7 tag
epon(GE-5)# vlan add 33 tag
3. Config OLT manage ip address:
epon# system ipconfig inband 192.168.1.119 255.255.255.0
epon# system ipconfig gateway 192.168.1.1
4. Enable the vlan function:
epon# swmode vlan enable
5. Config the ONU template and apply to all onu,the template config will apply to the ONU.
This template is for the 4port ONU (FD104GH or FD104HC), FD104HW is just 2port(eth1 and eth2) for the ONU and another 2port(lan1 and lan2) is for the wifi port – this ONU needs local web configuratio.
epon# system onu-template-config-user 2
epon(onu-template-2)# config capacity 0 4 0 test
epon(onu-template-2)# config uni 1 ctc vlan-mode tag 0x8100 0 7
epon(onu-template-2)# config uni 2 ctc vlan-mode tag 0x8100 0 7
epon(onu-template-2)# config uni 3 ctc vlan-mode tag 0x8100 0 33
epon(onu-template-2)# config uni 4 ctc vlan-mode tag 0x8100 0 33
epon(onu-template-2)# apply-to-all-onu 2
epon# system save all
Done …this is all …easy, right? Connected ONUs will lease configuration based on this template.
The word for the end:
1. Your network stands and fall on quality of products you used to build up your network.
2. Precision and doublechecks saves days of work.

IPQ6010 and IPQ8072:OFDMA support in Wifi6 Solution
Introduction:
In the dynamic landscape of wireless communication, the techniques employed play a crucial role in optimizing data transmission and overcoming challenges. Two key technologies, FDMA (Frequency Division Multiple Access) and OFDMA (Orthogonal Frequency Division Multiple Access), are pivotal in this context. This blog aims to unravel the disparities between FDMA and OFDMA, shedding light on their applications and significance in mitigating multipath interference, particularly in the realm of Wi-Fi.
The Need for Multiple Carrier Technologies:
To comprehend the essence of OFDMA, it’s imperative to first delve into the concept of OFDM (Orthogonal Frequency Division Multiplexing). OFDM is a multicarrier modulation technique designed to combat multipath interference encountered in wireless communication. Multipath interference occurs when radio waves encounter obstacles, causing reflections and refractions. This phenomenon results in multiple versions of the same signal reaching the receiver, leading to what is known as multipath interference.
The Challenge of Inter-Symbol Interference:
Multipath interference directly contributes to intersymbol interference (ISI). In the realm of wireless communication, ISI poses a challenge where, for a given set of serial signals, the receiver encounters difficulty distinguishing between them. This challenge arises when the time delay between two identical signals is less than the signal’s transmission interval. The outcome is known as inter-symbol interference, making it arduous for the receiver to accurately decipher the intended signals.
OFDM as a Solution:
OFDM addresses this issue by transforming high-speed serial data into parallel low-speed data streams, thereby reducing inter-symbol interference. However, OFDM comes with its own set of drawbacks. In Wi-Fi 4/5, where communication is single-user-centric, each data transmission occupies all available subcarriers. This results in inefficiencies when small data packets, such as instant messages or web browsing, are transmitted, as the entire bandwidth is underutilized.
Introduction of OFDMA:
In response to this inefficiency, Wi-Fi 6 introduced OFDMA, borrowing a page from 5G’s playbook. OFDMA, despite its name’s resemblance to OFDM, is fundamentally a multiple access technique. Multiple access techniques distinguish different users, and common methods include FDMA, TDMA, and CDMA.
FDMA vs. OFDMA:
FDMA relies on allocating different frequency channels to different users. In the analogy of a gathering, it’s akin to separating rooms for distinct conversations. On the other hand, OFDMA divides the channel into Resource Units (RUs), each orthogonal to the others. In our gathering analogy, OFDMA creates individual compartments within a room, facilitating multiple conversations simultaneously.
Enhancing Efficiency with OFDMA:
OFDMA optimizes spectral efficiency by scheduling users in specific resource units instead of utilizing the entire channel for a single user, as seen in traditional OFDM. It introduces a more flexible approach, akin to efficiently utilizing a delivery vehicle by allocating designated compartments for different recipients.
Conclusion:
In summary, while OFDM successfully addresses multipath interference by transforming data streams, OFDMA takes a step further by introducing an innovative multiple access technique. By adopting OFDMA, Wi-Fi 6 has elevated efficiency in point-to-multipoint communication, ensuring that a single cycle completes communication with multiple users. This evolution underscores the dynamic nature of wireless communication technologies, continually adapting to enhance performance and meet the demands of evolving applications.

PQ6010 AND IPQ8072:OFDMA SUPPORT IN WIFI6 SOLUTION
Introduction:
In the dynamic landscape of wireless communication, the techniques employed play a crucial role in optimizing data transmission and overcoming challenges. Two key technologies, FDMA (Frequency Division Multiple Access) and OFDMA (Orthogonal Frequency Division Multiple Access), are pivotal in this context. This blog aims to unravel the disparities between FDMA and OFDMA, shedding light on their applications and significance in mitigating multipath interference, particularly in the realm of Wi-Fi.
The Need for Multiple Carrier Technologies:
To comprehend the essence of OFDMA, it’s imperative to first delve into the concept of OFDM (Orthogonal Frequency Division Multiplexing). OFDM is a multicarrier modulation technique designed to combat multipath interference encountered in wireless communication. Multipath interference occurs when radio waves encounter obstacles, causing reflections and refractions. This phenomenon results in multiple versions of the same signal reaching the receiver, leading to what is known as multipath interference.
The Challenge of Inter-Symbol Interference:
Multipath interference directly contributes to intersymbol interference (ISI). In the realm of wireless communication, ISI poses a challenge where, for a given set of serial signals, the receiver encounters difficulty distinguishing between them. This challenge arises when the time delay between two identical signals is less than the signal’s transmission interval. The outcome is known as inter-symbol interference, making it arduous for the receiver to accurately decipher the intended signals.
OFDM as a Solution:
OFDM addresses this issue by transforming high-speed serial data into parallel low-speed data streams, thereby reducing inter-symbol interference. However, OFDM comes with its own set of drawbacks. In Wi-Fi 4/5, where communication is single-user-centric, each data transmission occupies all available subcarriers. This results in inefficiencies when small data packets, such as instant messages or web browsing, are transmitted, as the entire bandwidth is underutilized.
Introduction of OFDMA:
In response to this inefficiency, Wi-Fi 6 introduced OFDMA, borrowing a page from 5G’s playbook. OFDMA, despite its name’s resemblance to OFDM, is fundamentally a multiple access technique. Multiple access techniques distinguish different users, and common methods include FDMA, TDMA, and CDMA.
FDMA vs. OFDMA:
FDMA relies on allocating different frequency channels to different users. In the analogy of a gathering, it’s akin to separating rooms for distinct conversations. On the other hand, OFDMA divides the channel into Resource Units (RUs), each orthogonal to the others. In our gathering analogy, OFDMA creates individual compartments within a room, facilitating multiple conversations simultaneously.
Enhancing Efficiency with OFDMA:
OFDMA optimizes spectral efficiency by scheduling users in specific resource units instead of utilizing the entire channel for a single user, as seen in traditional OFDM. It introduces a more flexible approach, akin to efficiently utilizing a delivery vehicle by allocating designated compartments for different recipients.
Conclusion:
In summary, while OFDM successfully addresses multipath interference by transforming data streams, OFDMA takes a step further by introducing an innovative multiple access technique. By adopting OFDMA, Wi-Fi 6 has elevated efficiency in point-to-multipoint communication, ensuring that a single cycle completes communication with multiple users. This evolution underscores the dynamic nature of wireless communication technologies, continually adapting to enhance performance and meet the demands of evolving applications.
