Oh gosh, you mean they can actually boost networks?

Why don't do mobile operators do it all the time!

  Should do right sizing instead of over-sizing (this is the beauty of precise engineering) - so that price plan will be reasonable and not costly.
  
  Backend infrastructure with the advent of Ethernet – for Telcos which is called MetroEthernet – have no issue of boosting their bandwidth. From 10Mbps to 100Mbps to 1Gigabit to 10Gigabit – now with 40Gbps even to 100Gbps
  in the pipeline, the Ethernet technology bandwidth keep increasing exponentially.

  Even if one pipe of such high bandwidth is deem not sufficient, bandwidth can be aggregated by combining 2 or more port-channels and bundle into 1 thick pipe such as bundle 2 GE links from 1 GE to 2 GE bandwidth):-

  Interface port-channel 1
  Description etherchannel port 14
  Switchport mode trunk
  Switchport trunk encapsulation dot1q
  Switchport trunk allowed vlan 1,2,3,1002-1005

  Interface port-channel 2
  Description etherchannel port 15
  Switchport mode trunk
  Switchport trunk encapsulation dot1q
  Switchport trunk allowed vlan 1,2,3,1002-1005

  Vtp mode transparent

  Vlan2
  Name Vlan2-Etherchannel
  Mtu 1500

  Vlan3
  Name vlan3-etherchannel
  Mtu 1500

  Interface ge1/14
  Channel-group 1 mode active
  Switchport mode trunk
  Switchport trunk encapsulation dot1q
  Switchport trunk allowed vlan 1,2,3,1002-1005

  Interface ge1/15
  Channel-group 2 mode active
  Switchport mode trunk
  Switchport trunk encapsulation dot1q
  Switchport trunk allowed vlan 1,2,3,1002-1005

  The issue is the access point bandwidth – which can burst up – if there are too many human traffic appear at one place – that will cause congestion to the nearest access point base-station.

  For eg. If 1 base-station can handle concurrent 500 connection from 500 human mobile access, a surge of 1000 human at one location by connecting to the same access point base-station – will overload the base-station and cause congestion.

  If QoS (Quality of Service) are configured in the ingress port
  at the backend with rate-limit to discard congested packet, then many connections will be discarded. For eg.:-

  Rate-limit input qos-group 1 80000 1510 80000 conform-action transmit exceed-action drop

  Mobile base-station will help the surge of mobile access to be connected to it without overloading the standing base-station – only for this special event.

  After the event, the traffic load will drop back to normal and the mobile base-station will no longer be required.

  More practise make perfect – otherwise become rusty ………………

  does boost = uncap bandwidth?

    Bandwidth is not unlimited. There is always a cap
    to bandwidth.

    For eg. at the backend, bandwidth can be throttle
    based on monitored average bandwidth and spike bandwidth - so that spare bandwidth can be virtually provisioned for other used - this will not result in
    wastage.
    For eg. 1 GE is the maximum bandwidth. But if only
    5Mbps is used for the mobile phone, then the
    bandwidth will be throttle as below for used by mobile phone. :-

    access-list 1 permit 10.10.10.0
    access-list 2 permit 20.20.20.0
    traffic-shape group 1 5000000
    traffic-shape group 2 15000000

    The rest of the bandwidth can be virtually provision
    for other used.

    Virtual provision can be as follow :-

    ip vrf VRF-mobilephone
    rd 100:1

    ip vrf VRF-Internet
    rd 100:2

    int ge0/1.10
    description provision 5Mbps for mobilephone
    ip encapsulation dot1q 10
    ip vrf forwarding VRF-mobilephone
    ip address 10.10.10.10 255.255.255.0
    traffic-shape group 1 5000000

    int ge0/1.20
    description provision 15Mbps for Internet, and the
    rest of bandwidth reserved
    ip encapsulation dot1q 20
    ip vrf forwarding VRF-Internet
    ip address 20.20.20.20 255.255.255.0
    traffic-shape group 2 15000000

    However, if more bandwidth are required more than 1GE eg. 1.5GE, free GE ports can be provisioned by channelising eg. the free GE port to aggregate
    ports to together to thicken the pipe by
    Etherchannel or by Link Aggregation 802.1ad for
    layer 2 and load-balancing such as glbp for ingress
    port and bgp for egress port for layer 3.

    At the front end, if additional bandwidth are required, additional base-station such as the mobile
    base-station - can be used to the join wireless
    network to increase the connection caps.
