GSM and 5G data
We often take for granted the access we have to data & VOIP networks, esp. when we have 'unlimited access'
Unlimited data access is a farce
- My ISP still delivers ancient xDSL connections maxed a 10MBit/s (1MBit = 1024kBit!)
- The connection is capped at speed meaning 30days per bandwidth pool
- * 10MBit/s = 36000Mbit/hr
- * 36000Mbit/hr = 36864000 MBit/day (x24)
- * 36864000MBit/day = 1105920000 MBit/month (x 30 days)
- * 1105920000MBit /1024 = 1080000 MByte/month
- * 1080000MByte /1024 = 1054.6875 GByte/month
- * 1054.6875 /1024 = 1.02996826172 TByte theoretical bandwidth.
You get only 1.0299 TByte/month at max!
Subtract from that number 10% for protocol overhead ping delays retries and what not.
- * 1.0299 TByte - 0.10299TByte = 0.9269TByte
- * 0.9269 TByte = 949.1456 GByte max in practice
The practical cap is at 949.15GB per month
Similar calculations can be made for unlimited post paid POTS phone connections
- The cap is at time. No one talks 24hrs and can pay the phone bill, so the cap is also economical
- No unlimited services exist. All are capped by time*
- Subscriptions can be a way out to good deals
- One of my GSM providers gives 100 minute prepaid subsciptions for 6 months a year and two years
- The difference is startling in comparision with the regular price
- 100min = 4.5 USD per month subscribed prepaid 6 months
- 100min = 25 USD month prepaid!
Don't take your connections for granted.
- Many people (me included) drop permanent services due to economical & technical reasons
- * I dropped my xDSL connection because I need fibre connections to work. My ISP has the fibre optic cables & FAT terminals (fibre acces terminals) in the first part of the street.
- * * My ISP even made the power company change the poles in the whole street
- * * The EBS changed the poles in 40% of the project time, a record for them.
- * * My ISP betrayed us by still giving us FTTC instead of FTTH as promised in the whole street.
- * * My ISP has massive corruption problems, since they abused the grand for FTTH to give us obsolete FTTC equipment with xDSL
- * * Only areas without POTS cables got FTTH first, the rest was shoved on obsolete ancient FTTC equipment you cant buy new anymore globally
- * * The ISP makes double money since they cant charge more for FTTC minimal, but have to give 50MBit/s minimal because there are no lower caps allowed in the contract grand
- * * The FTTH connection als0 gets your POTS phone connected to it
- * * when a pole is ripped off due to a car hitting it, you are SOL without a seperate GSM / smart phone, because your POTS phone is now on a SPF (single point of failure).
- * On xDSL the lines are buried so POTS lines are safer
- I also dropped the xDSL service because the ammount of data I can download is pitiful on xDSL
- I can use the cash literally for food since they charge a massive USD 20/month for the ancient connection
