Distribution.
The calculating process of the first covering indicator difference is illustrated below.
Specifically, continue by taking 900MHz frequency range as an example, the existing net of 900MHz frequency range (this implementations is referred to as U900) and
Narrowband Internet of Things (the present embodiment is referred to as N900) total RRU of 900MHz frequency range mixes mould mode networking using radio frequency, and the two uses
Frequency range is identical, estimates narrowband Internet of Things coverage condition with the MR of the existing net of co-sited.Since two each networks have different applied fields
Scape, different standards, different terminal types etc., terminal mobility are different, and when estimation needs to consider propagation loss model and connects
By every influence factor in field strength model.
For propagation loss model, electromagnetic wave free-space propagation path loss model are as follows: Los=32.44+20lg d
(Km)+20lg f (MHz), wherein Los is propagation loss, unit dB；D is distance, and unit is Km；F is working frequency, single
Position is MHz.As f=900MHz, Los=91.48+20lgd (Km).
For receiving field strength model, RSS=Pt+Gr+Gt-Lc-Los specifically may is that, wherein RSS is that reception signal is strong
Degree；Pt is transmission power；Gr is receiving antenna gain；Gt is transmitter antenna gain (dBi)；Lc is the attenuation of cable and cable end；Los is
Free space loss.
Known to analysis:
(1) the same frequency range of N900 and U900, same paths loss.Actual path loss by atmosphere, block, penetration loss etc. because
Element influences, it is believed that the two is equivalent.
(2) the test signal configuration different transmission power influence of N900 and U900 receives field strength, it can be understood as receives function
Rate.Wherein, test signal (the can be understood as pilot signal) power configuration of U900 is 33dbm=2W, broadband system, pilot tone function
Rate is full frequency band；Test signal (the can be understood as reference signal) power configuration of N900 is 32.2dbm=1.66W, narrowband system
System, the power of each RE symbol.
(3) terminal receiving sensitivity with chip, receive the correlations such as antenna gain, antenna packages mode.
Based on above-mentioned analysis it is believed that: receive power=transmission power-path loss.Since N900 and U900 share a set of antenna
Feed system, and frequency range is identical, coupling loss is identical, and therefore, for the same covering position, there are following relationships: N receives function
Rate-U receives power=N transmission power-U transmission power-N path loss-U path loss.Again because two network path losses are identical, above-mentioned relation can be with
Be directly equivalent to: N receives power=U and receives power+N transmission power-U transmission power, wherein it is narrowband Internet of Things that N, which receives power,
The reception power of net, such as can be the reception power RSRP of downlink reference signal；It is the reception power now netted that U, which receives power,
Such as it can be received signal code power RSCP；N transmission power is the transmission power of narrowband Internet of Things, such as can be with reference to letter
Number RS transmission power；U transmission power is the transmission power now netted, such as can be Primary Common Control Physical Channel PCPICH transmitting function
Rate.U900RSCP covering can be obtained by U900MR as a result, the practical covering index situation of N900 is assessed with this coverage condition.
If the PCPICH transmission power of U900 is consistent with N900RS transmission power, the RSCP and N900 of U900 are tested respectively in same place
The available existing net of RSRP and narrowband internet-of-things terminal signal reception difference, estimate in final narrowband Internet of Things covering index
The effect plus the difference is needed in meter.
