A Guide on Disaggregated Cell Site Gateways

A cell site gateway is a device that aggregates mobile data traffic from the cellular access network and transports it back to the service provider’s core networks. This essentially makes the cell site route a component of the telecommunication backhaul network. Cell site refers to the cellular access network.

Aggregating data from cell sites means that a modern-day cell site router would be able to accommodate 2G, 3G and 4G cellular technologies. The 5G cell site gateway supports 5G technologies with various features to support QoE including time synchronization, connectivity as well as routing protocols.

Who Uses Cell Site Gateways?

Cell site routers are mainly used by telecommunications service providers although they do have some applications in 5G gateways in an IoT setting. The physical placement of the cell site router is typically in an outdoor cabinet or in a room at the cell site base station owned by the service provider. 

The cell site has to be within reach of the base band unit.

Data centers and cloud will play a big role in the digital transformation of 5G and 5G gateways. Service delivery will depend heavily on edge cloud processing and cloud interconnect services.

Now that you have working knowledge on cell site gateways, let’s get into disaggregated cell site gateways. 

DCSG

The disaggregated cell site gateway is a solution many service providers are deploying at their cell sites to perform multi-function backhauling. The DCSG combines the benefits from a versatile white box platform with an open networking ecosystem of developers to create its service features.

In other terms, it is an open network cell site router that has decoupled its software features from its hardware components. The cell site router is built as a white box platform using merchant silicon. It also has the capabilities to integrate network operating systems from different solution providers using standardized APIs.

DCSG opens the door for any developer to build their solution on top of the platform and enter the backhaul market. This spurs rapid innovation and introduces more vendors who have the potential to provide new and improved solutions for service providers.

What DCSG Can Do for Telecommunications

Aside from having a hand in IoT routers, DCSG is a solution that allows telecommunication service providers to deploy 5G networks efficiently and economically by removing barriers that are sometimes encountered. 

IoT routers are basically gateways that allow IoT devices and sensors to get out to the internet by leveraging the cellular WAN connections on the gateway router. Barriers like these are tackled by DCSG:

  • Limited availability of choice from proprietary solutions

  • Unreasonable licensing practices for multi-vendor integration

  • Limited interoperability to enable multi-vendor environments

  • Lack of hardware and software selection available to foster innovation

All these were problems faced by service providers when they were deploying cell site routers in their mobile networks during 2G, 3G and 3G deployments. You can use the 5G cell site gateway to tackle all these issues.

Should You Start From DCSG?

There are many parts of the network to deploy disaggregated and open network solutions but many service providers are starting with the DCSG. The reason why they are doing this is simple: 

Cell site is the simplest and fastest way to realize return on investment.

If you need more reasons to start with DCSG, stay with me:

  • Easy to start and with minimal investment

  • Traffic pattern is simpler than other parts of network

  • They can upgrade piecemeal and minimize disruption to other parts of carrier’s network

  • Prepare backhaul capacity for the surge of future traffic volumes

  • Enable access network to meet the demanding timing requirements of 5G RAN.

If you are a service provider and you are not well versed with disaggregated and open networking solutions, you can utilize DCSG as a way to better understand the implementation and maintenance processes.

Getting the Most Out of Your B2B Referral Program

Referral marketing is when you get your customers to tell their friends about you, it’s that simple. Before you even get any qualified referrals , you of course need to satisfy your current customer base to a certain extent.  Only then will they be confident enough to recommend you to their associates. As we are dealing with B2B businesses, the fact becomes a tad trickier because B2B is a lot less personal vis a vis B2C businesses.  How do you encourage your customers to recommend you? First stay in touch with them and have great products and customer service - of course. Why B2B Referral Marketing Works Any B2B referral marketing blog you read heaps praise upon praise on just how effective B2B referral management is and here is why: Referrals are Cheap Granted, it takes some time to get an effective B2B referral marketing program running. But once it's off the ground, it's basically having someone advertise you for free. After it’s up and running, the only thing it costs you

5 Amazing AI Video Generators

As AI technology continues to develop, we are seeing more and more amazing applications for it. One area that has seen a lot of development in recent years is video generation. Several AI video generators are now available to create realistic and stunning videos. This blog post will explore five of the best AI video generators available. AI-Generated Videos There are many AI video generators that can create stunning videos. However, the best AI video generators can create realistic and lifelike videos. Some of the best AI video generators use GANs or Generative Adversarial Networks. These networks can generate realistic images by learning from real data. The generator creates real images while the discriminator tries to determine if the image is real or fake. One of the advantages of using a GAN is that it can create videos that are indistinguishable from reality. This is why many people believe that GANs will eventually be used to generate realistic movies and TV shows. So far, the b

Understanding Safety in Industry 4.0

Industry 4.0 has brought about a level of automation never seen before in manufacturing. With the entire picture still developing, industry 4.0 safety demands constant upgrades of safeguards and safety procedures.  The technological advances have no limit and the same translates to the required safety procedures. When you hear industry 4.0, you think automation. As such, it is plausible to think safety is not that big an issue, which certainly isn’t the case. Safety in an industry 4.0 platform is usually geared towards facilitating safe interaction between humans and machines.   Why Industry 4.0 Safety Is a Tricky Affair To be fair, most of these machines come pre-equipped with an array of safeguards in their control systems.  The challenge comes in the sheer amount of education that these systems require. The owners and employees need to take in a lot of information about these machines and how to use them.  The rule is that all users should be well informed, trained, and continuousl
