OldSpottingThread (Ericsson Style) [Abandoned]
lilotimz replied to digiblur's topic in Network, Network Vision/LTE Deployment
Nope. Not a Sprint cabinet at all. -

Nope. NV uses 2 cabinets. -
It's actually in the range of 250k -> 1 million dollar per new cell site once you take into the cost of building it (easily $120-150k for physical work) then you gotta get the backhaul (another $50-100k depending on availability and ease to get it) and negotiating lease with the owner of the location you put the cell site on ($$$$). There's a reason T-mobile will not touch the rural sites before the urban sites.

This is and is not true. Latency is a big part when the page is comprised of lots of simple elements. Some of these modern pages, however, have +1MB data to load per page. Once the size per item begins to overshadow the number of items, the relevant statistic becomes bandwidth and not latency. 200ms to establish connections, which conclude 200ms later after carrying 150K each, would be rather fast. Think of if you had 80ms latency but to load each 150K item took 400ms. Overall, you are still feeling slower, despite the lower latency connection. That is why I say 5 mbps. I've done another post elsewhere as well that explains this. There is a certain limit (around 6 mbps) where connection speeds become mostly irrelevant for most things to do on a cell phone.

Your message states that the other vendors do not care about upgrading 3g and only focus on 4g which is incorrect. All cell sites in every city and rural area is getting 3g/4g upgrades. Vendors just do it in different orders.

That is incorrect. All three vendors are doing 4g and 3g upgrades but in a different manner. Ericsson and Samsung tends to bring 4G up first (if possible) due to the fact they do not have to care much for interference issues as LTE 1900 has never been deployed and they don't have to go trouble shooting for coverage issues such as working on EVDO 3g. Thus Ericsson and Samsung launches 4g predominately first or 4g/3g at the same time in areas where they do not have to launch in clusters. In high density areas, they'll have to launch 3g in clusters in order to minimize impact to customers. On the other hand, Alcatel-Lucent does 3g upgrades first and then 4g upgrades. Doing so gets the physical work done at a tower quickly regardless of the backhaul situation as they can and will utilize legacy backhaul for 3g whereas 4g can only be accepted with upgraded backhaul. Alcatel-Lucent also does 3g launches in clusters iirc.

It won't be long. Typically takes 2-3 weeks to get building permits if everything is done correctly and the fees are paid. Keep having the same mistakes on applications and I envision the contractors will get fired and new ones hired that know how to do things around these parts. Note ** This is for Sacramento, the city, itself. The surrounding localities to the east, northeast may be separated into their own little municipalities with its own rules and departments. Work may or may not be undergoing deployment in those areas as we speak but I do not have knowledge of it. Most of them are too lazy to post building permits online or requires fees to see said building permits...

How many antennas Per tower for?
lilotimz replied to Rukin1's topic in Network, Network Vision/LTE Deployment
The panels house the antennas. There are multiple antennas housed within the new Network Vision panels. Increase in efficiency and advancements in design allows for multiple antennas to be configured via a RRU and remotely adjusted. No longer do they need multiple panels / antennas on a rack to be pointed in a certain way to get specific coverage or alleviating load. Everything can be configured in one panel which saves money from tower leases and assorted other misc costs. -

I'll assume antennas = a network vision panel which contains the antennas. The majority of cell sites have 3 sectors with one new network vision panel per sector. In very high capacity cell sites or sectors, the Sprint may choose to utilize a second network vision panel in order to utilize more carriers. I know for a fact that Samsung will use two panels for a high capacity sector and the other vendors likely does the same. So the answer is multiple antennas per sector usually indicates a high capacity sector which requires additional carriers. -
You win the award of probably getting the first LTE signal in the market in the coming weeks! I've already marked it on my progress map. We have the exact locations of every Sprint cell site in the entire nation in every market and it's not that hard for any of us to easily determine where cell sites are given an approximate location. If the backhaul is ready at that site, I'll say it'll be up and running in 2-3 weeks. In your video, the contractors were removing the old PCS antennas. The coaxial cables to the base stations were rolled up in second rack so all they need to do is to install the new panels and RRU's and hook it up. That should take about a working week. -- Some crews are just unfriendly when they're in the middle of something and someone comes up and yells at them so they probably just wanted you to leave. It's always best to play dumb and ask them what they're doing so they can feel like a superior and "teach" you about their work.
